The maturity of jujube varieties is from the middle and late September to the early October of 10, and jujube has a jujube flavor. Before that, the dates listed were firewood and wood, so they could not be eaten at all.
Round dates are picked from trees, how to cook them?
Mainly moisturizing, ventilation is just wrong. We use controlled atmosphere storage here to keep the temperature at 8-10 degrees and the humidity constant, which can be insured for 2-3 months. It is impossible for us to have such conditions at home. However, you can take refrigerator insurance: carefully select the dates, there must be no traces of insect bites and bumps, and all dates should be carried with handles, otherwise they will start to deteriorate from these places, and then put the dates into plastic belts, exhaust the air, and put them in the refrigerator for refrigeration, which can be stored for 1 month. Personally, I think that the above method is only applicable to Zhanhua Dongzao, which has high value, delicious fresh fruit and high water content. Other small dates, zero dates and pear dates are not very delicious and valuable, so it is unnecessary to make drunken dates by drying them in the sun. If the jujube is refrigerated at a proper temperature to control the respiration, the change of jujube quality can be slowed down. Take Taiwan Province candied dates as an example. Put the dates in plastic bags, seal them and store them in the lower layer of the refrigerator < about 5 degrees C >. They will be preserved for about 20 days, and the color and flavor will remain unchanged. Pack winter jujube in a plastic bag, leave a little air in the bag, seal it, and put it on the refrigerator door. It is best to pack it in small bags, and eat it one at a time, so that it can be preserved for a long time.
How to preserve round dates?
1, put it in the sun for a few days. In order to prevent the jujube skin from blackening, spray a new high-fat film on the jujube, dry it and cool it, then put it in a jar, or spread it in a cool and ventilated place for a few days, then put it in the jar after drying, and then cover it with a wooden cover. You can also mix plant ash with dates and cover them in a barrel. 2, with 30 ~ 40 grams of salt, stir-fry and grind into powder. Sprinkle 500 grams of red dates with salt in layers, sprinkle them with new high-fat film and put them in a jar to seal them, so that the red dates will not be bad or salty. If there are more dates, increase the salt according to the above ratio. Other fruits can also be stored by the above methods.

nutritive value
Jujube, also known as wild kiwifruit, has the effects of anti-cancer and slowing down skin aging. At present, it has not been planted artificially and belongs to wild green fruit. The fruit is oval, about 3 cm long and about 1.5 cm in diameter. It is a rare wild green fruit with delicate pulp and sweet fruit flavor. Fruit has strong, antipyretic and astringent effects. But it is not suitable to eat more, which is easy to cause diarrhea.

Soil quality requirements of jujube growing environment
Jujube likes areas with sufficient sunlight, moderate rainfall and slightly high humidity, loose and well-ventilated sandy soil or sandy soil, or hilly and mountainous areas rich in decayed loose soil as gardens.
How many round dates are planted on an acre of land?
If it is afforestation, it is suggested that the plant spacing 1.5 meters square. If it is cultivated in nursery, it mainly depends on what specifications you plan to cultivate and sell. If it is sold in five years, the plant spacing can be 80 cm square, that is, 800- 1000 plants can be cultivated in one acre. ..
It is suggested to ask local agricultural experts.
How much is a round jujube seedling, more than a year?
1. Good seedlings. Try to avoid damage to the root system when raising seedlings. In order to facilitate planting, the main roots can be trimmed slightly after seedling emergence, which is beneficial to the seedlings to absorb water and improve the survival rate. 2. Fertilize. Dig a tree pit, apply high-quality organic fertilizer at the bottom, and fill it in when planting seedlings. 3. soak the roots. Before planting seedlings, the roots of seedlings are immersed in phosphate fertilizer and rooting powder solution for 20 minutes or dipped in phosphate fertilizer solution and planted immediately. The injured roots of seedlings not only heal quickly, but also are prone to rooting. 4. plant seedlings. The saplings should be planted in the center of the tree pit. When filling the soil, the fertile topsoil should be filled in the rhizosphere and the heart soil should be cultivated in the upper layer. When planting, the seedlings should be shaken while filling the soil, so that the roots can be fully extended and closely connected with the soil. Step 5 water it. After the seedling roots are fixed, they should be watered with water, and then the tree tray should be adjusted and cultivated into a round pile, which is beneficial to wind protection and moisture conservation. 6. film mulching. Covering the planted jujube tree tray with plastic film can not only preserve moisture, but also make the seedlings overwinter safely, and the survival rate of jujube seedlings is high. 7. Cold protection. Jujube seedlings have thin cortex, low water content and easy evaporation, so methods such as covering with plastic film, wrapping and protecting trees can be adopted to prevent cold.
Can wild Zizyphus jujuba bear fruit and yield high after several years of planting?
It is mainly wild and bears fruit in about three years.
Jujube is mainly produced in the first vein of Changbai Mountain, belonging to perennial woody plants, mainly growing in the depths of deep forests. Because of its long growth period and the need for tall carriers to grow around it, there is no artificial planting at present.
Wild kiwifruit is the king of precious wild fruits and is known as "the precious fruit of the world". Wild kiwifruit grows in virgin forests with fertile soil, and its fresh fruit ripens from August to September every year. It is a berry vine fruit tree, and its fruit name is Kiwi, commonly known as "Jujube".
The underground root system of jujube tree is huge. Some people cut open the adult tree and found the juice flowing out. According to the local explanation, this juice has a certain medicinal effect among the people. Smell it with a faint taste, but taste it slightly sour. Occasionally, in the mountains, the destructive harvesting or juice collection in the previous year led to the unhealed incision and continuous loss of sap in the next year, and a shallow puddle was formed under the tree, surrounded by fungi. The loss of nutrients in the following year proved that jujube trees could not bear fruit for several years at a time.
