Why is farmyard manure more delicious than chemical fertilizer? Air-dried chicken manure improves the quality of agricultural products and reduces the accumulation of harmful substances, which is why vegetables and fruits using farmyard manure, especially leafy vegetables, are always sweeter than those using chemical fertilizers. For example, watermelon with more dried chicken manure or farmyard manure is sweeter than watermelon with only chemical fertilizer. The application of dried chicken manure can further improve agricultural products or realize green food.
There are so many pests in rice that it will be delicious. Pesticides can be divided into contact killing type (contact death), stomach poisoning type (feeding death), fumigation type (volatilization into the body through stomata to die), trapping type (attracting pests to die or stick through color, smell and taste) and so on. Some people have two or more types.
Why the application of organic fertilizer to improve the quality of agricultural products is a relatively single nutrient, generally only nitrogen, phosphorus, potassium, boron, zinc, molybdenum and other nutrients, these nutrients can only play a major role in growth, and plants need many other elements besides these main elements, and organic fertilizer contains other trace elements besides the main elements. When plants absorb complete nutrition, they will grow healthily, and the fruits will have comprehensive nutrition and good quality. For example, the watermelon we often eat is not sweet with chemical fertilizer, but obviously sweet with organic fertilizer.
Are agricultural products that only use chemical fertilizers without using pesticides green and pollution-free products? number
Green products and pollution-free products are two concepts.
Pollution-free products refer to pollution-free products that are produced according to the corresponding production technical standards, meet the general hygiene standards and are recognized by relevant departments.
Green products refer to:
It is required that chemical synthetic fertilizers, pesticides, veterinary drugs and feed additives shall not be used in the production process.
Additives, food additives and other substances harmful to the environment and health.
Only those who meet the above requirements can become green and pollution-free, but they generally meet the standards of green products and meet the requirements of pollution-free, because pollution-free is the basic requirement.
Do pesticides and fertilizers pollute the environment? Pesticides and fertilizers contain chemical elements. Especially in pesticides, volatilization into the air will pollute the air. Water-soluble fertilizer will be better, because the nutrients in it make the land more fertile and the pollution is not so serious. The production technology of water-soluble fertilizer in Dehua, Henan Province will be better. Just use less residual impurities. I hope I can help you.
You can increase production without applying chemical fertilizer. China Agrochemical Network "Farming without chemical fertilizer can increase production without increasing costs." In the vegetable greenhouse in Wen Chun Town, Xi District, Mudanjiang City, Sun Zhicai, chairman of Zhongshan Straw Biological Planting Cooperative, said with great interest.
"How to increase production without chemical fertilizer?" Sun Zhicai said: "Our vegetable greenhouse does not need any chemical fertilizer, but relies on straw corruption to return to the field." Lao Sun said that under the action of microbial strains and purifying agents, straw is transformed into carbon dioxide, heat and organic nutrients needed for plant growth, achieving high yield and high quality of crops.
Lao Sun said: "It costs more than 2,000 yuan to plant an acre of cantaloupe in a conventional way. Using this straw bioreactor technology, one acre of land in 50 yuan needs 10 bag of strain mixture, and two bags of wheat bran in 500 yuan and 80 yuan, totaling 160 yuan. In addition, labor costs such as laying straw and spreading strains need 800 yuan, and the cost per mu is 1500 yuan. Old sun picked up a thermometer from the ground to check the ground temperature, which showed that it was MINUS 20 degrees. He said, "The straw under the soil releases heat during fermentation, and the ground temperature is 5-6 degrees Celsius higher than that of conventional planting, so the time to market can be advanced. Vegetables in greenhouses cost one price a day, and may be sold for one yuan a catty a day earlier. "
When it comes to specific operations, Lao Sun said that it is more troublesome than normal use of chemical fertilizers. After ditching and leveling, spread the straw evenly, sprinkle with specific strains, and then seal the soil. At each ridge head, you can also see straw that is not completely covered. In addition to the straw under the soil, these "built-in reactors" also have a carbon dioxide release device across the greenhouse, which is connected with the external reactor for fermenting the straw, and the carbon dioxide generated by straw fermentation is continuously released into the greenhouse. Lao Sun said that the cantaloupe he planted in March will be almost on the market in a month. Because it is a green and organic fruit and vegetable food, it is estimated that cantaloupe can sell 15 yuan per catty, which is several times higher than that of ordinary cantaloupe.
Green melon seedlings are already more than half a foot high, and some have already blossomed small yellow flowers. In addition to fruits and vegetables, Lao Sun will try to popularize this technology in dry and paddy fields this year. In his strain mixing room, several farmers are stepping up the crushing of straw to prepare for the spring ploughing production that began in early May. (China Agricultural News Network)
He does not use pesticides and fertilizers, and is a pure natural farm green and healthy food. His own vegetables are pure natural farm green and healthy food without pesticides and fertilizers. His father ate his own vegetables and fruits, and our brothers took them away, and many of them were returned to his neighbors.
Hello, are there any agricultural products without pesticides and fertilizers? The agricultural products you mentioned are basically close to organic food. Because at present, the environment in most parts of China is not absolutely organic. This kind of organic products are few, the output is not high and the price is high. Generally there are some in the western region. Such as tartary buckwheat.
hope this helps
