In recent years, with the rising price of winter jujube, farmers who grow winter jujube seedlings can be said to be more and more. Some farmers blindly follow the wind and blindly plant winter jujube without knowing the management techniques of winter jujube seedlings, resulting in low yield and quality decline of winter jujube. . What are the fertilizer management techniques for winter jujube seedlings?

     The growth of winter jujube seedlings is fast. When the plants are planted in the same year, even if they are planted in July and August, they can still bear fruit. According to the test, planted in 2-3 months, each plant can be hung about 20 kg in the same year; planted in April-May, each plant can bear fruit 10-15 kg; planted in July-August, 2-3 kg per fruit in the same year; Planted in September-October, there are still a few results in the year. In the second year, the plant can produce more than 50 kilograms. After three or four years, the plant can produce more than 200 kilograms, the yield per mu can reach more than 6,000 kilograms, and it can produce high yields every year. There are almost no large and small years, and the high yield period can reach 20 years. the above. Jujube seedlings mature in winter, the harvest period is up to 3-4 months, avoiding competition with other fruits, storage and transportation is also convenient, can be kept fresh at room temperature for more than 10 days, can be kept fresh for more than 30 days at low temperature, can be easily Shipped to all parts of the country for sales, not only sales, but also high prices.

    1. Winter jujube seedling foliar spray: After the fruit is harvested, spray 0.3-0.5% potassium dihydrogen phosphate as soon as possible to increase the nutrient accumulation of the tree, promote leaf assimilation and branching, and enhance the tree potential to facilitate wintering.

    2, winter jujube seed application base fertilizer: the base fertilizer was applied at the beginning of October. In the initial fruiting period, each plant is applied with 20-30 kg of decomposed farmyard manure; in the fruiting period, 30-50 kg is applied per plant, and with 0.5-1.0 kg of urea, compound fertilizer (nitrogen: phosphorus: potassium = 15:12:15) ) 1.5 kg. It is applied by radial ditch application. It is the starting point at 1/2 of the tree plate, and the outer end is aligned with the outer edge of the canopy. Dig 7-9 radial grooves, 30-40 cm deep and 40 cm wide, will be mixed well. The fertilizer is scattered into the ditch and then covered with a layer of soil.

    3, winter jujube seedling irrigation: the first water after the fruit is harvested, the amount of irrigation depends on the soil moisture, so that the soil moisture is most conducive to the growth and development of plum trees. When filling the water, the ditch is 20-25 cm deep between the Liyuan line. The ditch is preferably perpendicular to the water channel. After filling the water, fill the ditch in time.
