Jujube management: how to increase the yield of jujube?

How to increase the yield of jujube? How to improve the quality of jujube? Please introduce the methods of planting jujube trees. If you want to improve the yield and quality of jujube trees, you can refer to the following methods for management: 1. Apply enough organic fertilizer and phosphorus and potassium fertilizer. Years of practice has proved that pure nitrogen, phosphorus pentoxide and potassium are needed for every 100 kilograms of fresh jujube. Organic fertilizer and phosphorus and potassium fertilizer should be fully applied to produce pollution-free, high-quality and high-yield jujube. Organic fertilizer was applied to a soil layer of 30cm in 20ml twice before flowering in early spring and fruit harvest in autumn, with 30kg of organic fertilizer and 1kg of compound fertilizer applied to each plant. When the jujube trees enter the full fruit stage, they only need topdressing 3 times a year, that is, budding fertilizer, flowering fertilizer and fruit fertilizer, combined with watering. 2. Spraying growth regulators and micro-fertilizers to protect flowers and fruits. Jujube trees were sprayed with the mixture of 10-15ppm gibberellin, 0.1% boric acid, 0.2% potassium dihydrogen phosphate and 0.5% urea for 3 times during full flowering and fruit expansion. 3. Opening armour at flowering stage. Nail opening can control the growth of root system and aboveground branches and leaves of jujube, so that flowers and fruits can get more nutrition and improve fruit setting rate. Nail opening method: the first nail opening shall be carried out at a height of 20m / 30cm from the ground when it blossoms at 30%. The nail-opening part moves up about 5 cm a year, and when it moves to the trunk branch, it starts to return to the nail from the lower part. After nail opening, 300 times high efficiency imidacloprid insecticide was applied to protect the nail mouth. 4. Release bees at flowering stage. Using insect pollination to improve fruit setting rate. 5. Spray water at flowering stage. The suitable air relative humidity for pollination at flowering stage is 70% Mur80%. When the humidity is less than 40%-50%, the pollen is stunted. Therefore, in the case of high temperature and drought during the flowering period, water should be sprayed at 3-5 p. M., once every 3 days, and 3 times in a row to promote pollination and flower bud germination. 6. Prevent fruit from cracking. Spraying 3000ppm calcium chloride solution or 0.1% zinc sulfate solution every semimonthly since late July can effectively reduce fruit cracking. 7. timely prevention and control of diseases and insect pests. Many kinds of fungicides such as Bordeaux liquid, green milk copper, streptomycin and so on can be used to control diseases and insect pests. Insect pests such as shell insects, heart-eating insects, red spiders and bug bugs can be sprayed once every 10 days with biological pesticides or cypermethrin pesticides with high efficiency and low toxicity. 8. Speed up fruit harvest. The ethylene solution of 200-300ppm was sprayed one week before harvest to promote fruit ripening and increase sugar content.
