What's the function besides extracting tea oil? 1, oil tea cake, as a natural fertilizer, can increase fertilizer, loosen soil and kill insects.
Mash the oil tea cake with a sledgehammer and scatter it in the paddy field. In this way, crops grow well in one year, which is a high-quality fertilizer for planting pollution-free vegetables and flowers and fruits.
2. Wash farm tools with dry tea.
Mash the tea cake, filter out the dead residue, and wash it with the remaining tea leaves.
3. Extract camellia polysaccharides, polyphenols, peptides, flavonoids and other components, and develop a series of high value-added products such as green health food and green biological feed.
4. As feed, the protein content of fermented Camellia oleifera meal is as high as 20%, which is an excellent feed source for livestock and poultry.
However, it can not be directly used as feed, and can only be used for raising livestock and poultry or aquaculture after removing saponins and toxins.
Extended data
Camellia oleifera likes warmth and is afraid of cold. The annual average temperature 16 ~ 18℃ and the flowering average temperature 12 ~ 13℃ are required.
Sudden low temperature or late frost will cause falling flowers and fruits.
Sufficient sunshine is needed, otherwise only branches and leaves will grow, resulting in less results and low oil content.
Sufficient moisture is needed, and the annual precipitation is generally above 1000 mm, but continuous rainfall at flowering stage affects pollination.
It is required to plant in a place with gentle slope and weak erosion, and the requirements for soil are not strict. Generally, it is suitable for acid soil with deep soil layer, not for places with many stones and hard soil.
The unsaturated fatty acid content of tea oil is as high as 90%, which is much higher than that of vegetable oil, peanut oil and soybean oil, twice as much as that of olive oil with vitamin E, and contains certain physiological active substances such as camellia glycoside, which has extremely high nutritional value.
Tea shell is also a good culture medium for edible fungi.
Studies have shown that tea saponin also has antibacterial and antioxidant effects.
In addition, Camellia oleifera is an excellent nectar and pollen source plant in winter, and its flowering period is in the season with few flowers. In the first ten days of 10 ~ 12, honey powder was extremely rich.
Camellia oleifera also has high application value in biomass energy.
At the same time, Camellia oleifera is a tree species with strong anti-pollution ability, which has strong anti-sulfur dioxide, anti-fluorine and chlorine absorption ability.
Therefore, scientific management of Camellia oleifera forest has ecological benefits of soil and water conservation, water conservation and climate regulation.

What method can be used to get rid of leeches in rice fields? In the 1950s and 1960s, there were leeches where there was water. At that time, leeches were everywhere.
If the foot of a paddy field is covered with bite marks, people who have never planted the land will cry when they see it.
It is not terrible to get used to it in the countryside. Leeches mainly suck the blood of animals and reproduce quite quickly in water.
There are leeches in wet woodlands, and leeches in woodlands are particularly painful and itchy.
Leeches are rarely seen in the fields now, and they are mainly killed by pesticides and fertilizers.
Leeches are most afraid of lime pesticides and fertilizers, which are the bane of leeches and the most effective.
Speaking of leeches, it's awesome and terrible. If you have bitten on your feet and sucked blood, you are fearless. It would be even more terrible to see leeches leaping from the side.
In the 1960s, leeches in rice fields were all killed by lime.
Lime can also control rice diseases and pests.
Now, there is no lime in rice fields.
Leech is an amphibious invertebrate, which mainly swims in water and crawls on land. They usually feed on animal blood. Speaking of leeches in rice fields, the fifties and sixties were the most abundant in rice fields. They mainly like to live in cold water fields, ponds and reservoirs deep in mountain villages, and bite people and animals when they see them.
In the past, there was a saying in our countryside that "grasshoppers listen to the sound of water, and beggars call drums", which means that as long as grasshoppers in the field hear someone moving, cows harrowing the fields, loaches and eels crawling, frogs and snakes making water circles, grasshoppers in the fields will plunge into the crowd and chase after them. Bend down to the ground, and accidentally your feet are covered with bloodsucking grasshoppers.
Leeches also have a special function. There is a substance in their body fluids. When they suck the blood of animals, it is painless and easy to paralyze people.
From the above analysis, we can all see that leeches are really harmful amphibians and need to be eliminated. So what can be done to eliminate leeches in rice fields?
From the point of view of environmental protection, we can usually use 150-200 kg of fresh raw stone per mu of rice field during the first rice rotation or during transplanting and intertillage, and use the high temperature and alkalization of quicklime when it meets water to kill locusts in the field. Quicklime can also change the soil quality, which has two functions.
The second method is to hammer the rapeseed cake, put it in a bucket, add some spicy herbs, soak it in boiling water for 2 hours according to the ratio of 1: 10, and then pour the oil tea cake and spicy herbs into the field water with a ladle at noon on a sunny day. In less than two hours, all the grasshoppers in the field will die and the tea cakes will wither.
The third method is to use ammonium bicarbonate as rice base fertilizer after ploughing, and poison leeches with ammonia gas volatilized from ammonium bicarbonate.
In addition, when we grow rice, other chemical pesticides are leeches' killers, which can kill leeches in rice fields.
what do you think? Welcome to comment!
[Love life, like communication, please collect more answers from Qixing farmers, thank you very much! ]
Leeches are also called grasshoppers, and they are also called grasshoppers here.
I also have a lingering fear of leeches. I remember when I was a child, I was often stuck to my feet by leeches when I was transplanting rice with my parents.
Leech mainly sucks blood, and soon it will unconsciously climb to the root of your feet when you enter the water.
It will let go and swim slowly when it is full of blood.
What should I do if I meet leeches when transplanting rice? You can find something to hit it, or rub it with river sand, and you can drive the leeches away.
Now there are few leeches in rice fields, and many leeches have been killed because of using pesticides. Not only leeches, but also other small animals, such as loach and eel, are rarely seen.
I remember that in the past, besides grasshoppers, there were many loaches and ricefield eels in the fields, but now more drugs are used, which leads to less and less.
Therefore, the use of pesticides is also one of the ways to eliminate leeches.
Because when rice is planted, it will be sprayed with pesticides. These pesticides can help you get rid of leeches.
Besides using pesticides to remove leeches, other methods can be used.
For example, use quicklime.
Sprinkle quicklime evenly in the rice field, stop the water from entering, and dry for a few days.
It won't be long before leeches are wiped out.
Another method is to use oil tea cakes to get rid of grasshoppers. Camellia oleifera cake is the oil residue squeezed from Camellia oleifera seeds.
Our countryside is also the main area where camellia oleifera seeds are planted.
The output of tea oil is also relatively high.
I remember some villagers used oil tea cakes to get rid of leeches.
Oil tea cake has the function of killing insects. When it spreads in rice fields, it can not only repel leeches, but also repel other pests.
But everyone should also pay attention to the fact that you should not sprinkle oil cakes in the fish pond, which may be given by the fish in the fish pond.
These are some methods commonly used by our farmers to get rid of grasshoppers. There are other good ways to share messages. Thank you.
Cai Xiaoshan's hometown has rice fields. Rice is planted twice a year, and there are leeches in the rice fields. There were many leeches in the early years, but now there are fewer. Then what method can be used to get rid of leeches in rice fields? Let's say:
1, ploughing and drying rice fields in autumn and winter
Leeches live in water, so they can't live without water. Therefore, to get rid of leeches in rice fields is to drain the water in rice fields; This practice is usually difficult to do, usually after the autumn harvest. After the autumn harvest, there is less water in the rice fields. In addition, it is windy and dry in autumn and winter, and it seldom rains. The plowed rice fields are exposed to the sun, which makes leeches hidden in the mud have no hiding place and the living environment is destroyed. Paddy fields with higher terrain are more prone to drought in autumn and winter. People in rural areas generally like to do this, and the operation is simple. After several months in autumn and winter, leeches rarely appear in paddy fields during spring ploughing.
Step 2 use quicklime
Leeches are fleshy, have no protective shell, and are vulnerable to some irritating things. Quicklime is alkaline, and it will produce a high fever when it reacts with water, which leeches can't stand, but quicklime is not difficult to obtain. Among rural farmers, leeches in rice fields are usually killed by spreading quicklime after ploughing and before transplanting, and waiting for 3-5 days.
Of course, if the paddy field is large and the amount of quicklime is large, farmers are generally reluctant to use quicklime. Generally, they choose to plough in autumn and winter to expose paddy fields.
Step 3 use peanut cakes
The peanut cake here refers to the residue left after the peanuts in rural areas are squeezed out of the soil. The local dialect in my hometown is Mahuo. Peanuts of rural people used to be used after oil extraction. Some are used to feed pigs, and some are used to fertilize in Abel Tamata, saying that it can kill insects and fertilize in Abel Tamata.
4. Control pests and indirectly remove leeches.
Of course, there will be pests when rice is planted in rice fields. People spray pesticides to control pests, and those pests are the food of leeches, which will indirectly remove leeches. This is one of the reasons why people do not deliberately remove leeches, but leeches in rice fields are becoming less and less.
What method can be used to get rid of leeches in rice fields?
When it comes to leeches, some people will be scared and have a lingering fear.
Especially the girls who grew up in the countryside, or the educated youth who were sent from the city to the countryside, were once afraid of being bitten by grasshoppers.
Leech is an amphibious reptile, which often lives in fresh water or on the leaves of vegetables on the shore.
Leeches are not easy to attack people and animals on the shore, but when people and animals go down to paddy fields, they become their sacrifices. There is always a lot of bright red blood on the feet and legs bitten by leeches.
Sometimes it's hard to get rid of it, scaring many girls to call their parents in tears.
I remember catching earthworms in the fields when I was a child. I was bitten by a grasshopper. I can't get rid of the bleeding. I ran home crying and told my father that I was bitten by a grasshopper and couldn't get off.
Dad comforted me not to cry and not to be afraid, so he slapped my calf twice with his big palm and the grasshopper fell down.
Later, my father brought cooking salt from home and sprinkled it on the leeches.
Soon, the leeches tossed and turned on the ground, and a large amount of greasy liquid penetrated from their bodies. Finally, the leech became smaller and smaller and died.
From this point, it can be proved that what leeches fear most is salt.
But there are many and deep waters in the paddy field, so how much edible salt should be given to kill leeches at a time! This seems unrealistic.
I remember that when the production team transplanted rice, the team would sprinkle quicklime before transplanting rice, and then rake it, and the leeches would be released.
Later, all kinds of highly toxic pesticides were used more and leeches were less and less.
Now working in paddy fields, I am no longer afraid of being bitten by grasshoppers. With the invention, production and popularization of rice socks, farmers put on rice socks when working in rice fields.
Are there any leeches in rural paddy fields?
Catch it, dry it, sell it to a drugstore,
The best choice of quicklime
Spraying dry lime powder in rice fields is the most effective and pollution-free method to kill leeches.
Although killing with highly toxic pesticides is very effective, there will be pesticide residues, which will also have an impact on farmers and future agricultural plants.
The effect of using dichlorvos with low toxicity and residue is not ideal.
Leech will fester and die after being polluted by lime powder, and it will also die of physiological acid-base imbalance in alkaline water with lime.
However, the strong alkalinity of lime can only be maintained for a short time, and it can be diffused and desalinated after pest control, which is also beneficial to the improvement of strongly acidic old swamp soil.
When leeches bite you, don't pull them out with your hands.
Because leeches have two suckers, it may make them suck more tightly.
At the same time, hard pulling will cause its mouthparts to rupture under the skin, causing infection.
After being sucked by leeches, you can pat your arms, thighs or other bitten places. This electric shock will make leeches fall off.
Or coat the leeches with concentrated brine, or with soapy water, tobacco oil, wine, vinegar, etc.
Soon, leeches will fall to the ground.
Why do people bleed when bitten by leeches?
The saliva it secretes when it bites people contains an anticoagulant, also called hirudin, which can make the blood of the wound not coagulate. So after a person is bitten by a leech, the wound will bleed.
This is a wonderful way for leeches to be greedy. There are suction cups at the front and back ends of their bodies, which can be used to adsorb their bodies on human skin and continue to suck.
If you are bitten by a leech, you can squeeze some blood from the wound by hand, so that you can stop the bleeding.
There are not as many leeches in the farmland as before! Not only leeches, but also loach, eel, blue crab and small crucian carp.
Leech, also known as leech, is a mollusk that feeds on animal blood and lives.
Many people are a little scared when they see this soft thing, and rural people rarely take it seriously.
There are many ways to eliminate leeches, so I'll tell you a few today:
1, Lime: Lime can be used not only for building renovation, but also in many rural areas.
Sprinkling on soil can neutralize the soil, sprinkling on vegetables can remove snails, and can also be used to make rice tofu at home and disinfect fish ponds.
If you want to eliminate leeches, you should fill the plowed farmland with water, sprinkle 30 kg of quicklime powder on each mu, and turn off the water to bask in the sun for a few days, not to mention leeches. As long as you swim in the field, you can't run away (except frogs).
People must wear water boots when spreading quicklime to avoid being scalded by quicklime.
The second kind, tea withered: many people may not know what this is. This is the tea cake left over from southern tea seed oil.
In the south, when there is no washing powder and soap, it is used to wash clothes where the tea leaves are withered.
The dead leaves of tea contain a special substance called tea saponin, which can enter the blood through the gills of fish and make the fish hemolyze and die. Many people in rural areas use tea leaves to poison fish.
Tea blight can not only poison fish, but also easily deal with leeches, loaches and eels without much effort.
Now it's all mechanized operations, and there are not many times to go to the fields. Farmers seldom use this method to poison leeches, eels and loaches.
The third kind, ammonium bicarbonate: Speaking of this kind, people who know and use this kind of fertilizer are no longer young.
This is what we rural people often call ammonium bicarbonate. Now compound fertilizer is used, and few people use ammonium bicarbonate.
Turn off the water and sprinkle ammonia on the ploughed fields. When it comes to water, it's especially cold and choking. If you don't get it, your tears will suffocate you.
After turning off the water for three days, the bigger the sun, the faster the leeches die, and other loaches, eels and small miscellaneous fish can't escape.
How is the bathing effect of oil tea cake? You'd better not take a bath with oil tea cake directly, because oil tea cake has not been processed, and there are many chemical components in it, which have certain influence on scalp.
Can you eat tea oil often? Can tea seed oil be eaten every day?
Tea oil is tea seed oil.
It can be eaten for a long time, but no matter what kind of edible oil, it is not good for a long time, which will lead to unbalanced nutrition and partial overnutrition, so it is better to replace it.
Tea oil is rich in vitamin E, fatty acids and camellia glycosides, and the content of monounsaturated fatty acids is over 78%, ranking first among all kinds of vegetable oils. It is beneficial to prevent and treat cardiovascular and cerebrovascular diseases, obesity and other rich diseases, improve human immunity, improve gastrointestinal function, have obvious effects on lowering cholesterol and resisting cancer, and play an important role in enhancing the intelligence and memory of fetuses and infants, promoting brain development and improving IQ.
Healthy and low in fat, as a high-end oil in the market, tea oil is suitable for almost all people, especially those who need to prevent' three highs', pregnant women and infants with intellectual development.

How to choose good tea seed oil
Look at the name and classification
According to the standard vegetable oil theory, tea oil can be divided into tea seed oil crude oil and refined tea oil according to its grade.
The latest edible oil standard solution clearly stipulates that crude oil (crude oil) cannot be directly used as edible oil.
Look at the processing technology
At present, processing technology is divided into pressing method and leaching method.
Squeezed tea oil is the oil obtained by physical squeezing of camellia oleifera seeds, which is essentially different from the method of extracting oil from camellia oleifera cake by chemical solvent.
According to China's new "Edible Oil Management Measures", the processing method of edible oil must be named "squeezing method" or "leaching method" on the label.
Look at the place of origin
The origin also has a certain influence on the quality.
The quality of tea oil is related to geographical conditions such as tree species, climate, latitude and longitude.
At present, tea oil in some parts of China has obtained geographical indications.
Zhi product certification, tea oil industry has become a local characteristic industry.
Look at the packaging
Tea oil is sensitive to light. If the light is continuous or strong, tea oil is easily oxidized. Therefore, it is recommended to buy a PET bottle or gift box that is not easy to transmit light.
After such a long time, the nutrition in tea oil is not easy to be destroyed.
In addition, it depends on the shelf life on the packaging label and whether there is QS certification.
Look at the quality
The quality of tea oil, on the one hand, requires the internal physical and chemical indicators to meet the standards, on the other hand, it needs sensory judgment.
Pour the tea oil to be evaluated into a small glass, hold the palm close to the bottom of the glass, gently shake it, and slowly heat the tea oil with the temperature of the palm. High-quality tea oil has the following characteristics:
(1) The oil body is bright and golden.
(2) It has a strong aroma of tea oil.
(3) The taste is smooth, and there is obvious tea oil fragrance behind the throat.

Camellia oil is very expensive to make cakes. Camellia oil contains many functional components. Long-term consumption has obvious effects on preventing cardiovascular sclerosis, lowering blood pressure, lowering blood lipid and preventing cancer. It can also moisten intestines, clear stomach, detoxify and sterilize.
Is the oil tea cake sterilized? Oil tea cake can sterilize.
Camellia oleifera is a hemolytic toxin, which can hemolyze bacterial cells and achieve disinfection and sterilization.
Oil tea cake, also known as tea cake, is rich in nutrition, and its value is equivalent to that of rice bran. It is a kind of feed worth developing and utilizing in protein.
However, the oil tea cake contains toxic saponin and tannin which affect the palatability of livestock, and it must be properly treated before it can be used as feed.
This is the end of the introduction about the efficacy and function of tea oil cake and what the efficacy of tea oil cake is. I wonder if you have found the information you need? If you want to know more about this, remember to collect this website.
