Management measures after jujube harvesting fruit
After jujube harvesting, in order to ensure more results in the coming year, the management of the jujube garden must be strengthened so as to restore the tree potential as soon as possible. The main management measures are: 1, Shi good fruit fertilizer. The harvested fruit fertilizer was taken by combining organic fertilizer applied on the root ditch and foliar spraying of quick-acting fertilizer. The foliar fertilizer was applied immediately after the fruit was picked, and the nutrient deficiency caused by the significant decrease in the absorption of the nutrient by the jujube tree due to the roots was significantly reduced, premature defoliation was avoided, and the photosynthetic efficiency in the later period was increased, so that the jujube tree accumulated more photosynthetic products. Use 0.3%-0.4% urea and 0.2%-0.3% potassium dihydrogen phosphate mixed solution, spray once every 7 days or so, even spray 2 times -3 times. Organic fertilizer is applied 4 to 5 days after fruit harvesting. Generally, 50 to 60 kg of pig manure or 100 kg of waste compost is used for each plant. After the ditch is applied near the base of the jujube tree, the soil is applied immediately after application. 2, deep to earth. To cultivate the jujube tree in winter can deepen the soil layer and enhance the ability to dry, keep the soil and keep fertilizer. The method of soil cultivation is to cultivate soil 17 centimeters to 30 centimeters thick within one meter of the radius of the jujube tree trunk. For a date garden with poor soil, lack of organic matter, and shallow cultivation, measures can be taken to deepen the soil and reduce soil pressure, so as to deepen the tillage layer, increase soil porosity, loosen the soil, and increase fertility. When the soil is changed, it is 100 centimeters wide and 80 centimeters deep. It uses organic fertilizer 500 kilograms per mu. 3, winter pruning. After the jujube deciduous, it must be pruned in winter. The focus is to remove dry and dead branches, diseased shoots, overlapping branches, delicate pendulous branches, and branches that affect the tree shape and aging. By pruning, keep the branches evenly distributed and the crowns are airy and transparent. When cutting in winter, the extension branches of all kinds of backbone sticks should be preserved, and attention should be paid to the smoothness of cuts and not to hurt the trees. 4, apply enough winter fertilizer. Before wintering, the winter jujube should be applied once to the jujube trees to lay a solid foundation for the growth and high yield of jujube trees in the coming year. Winter fertilizer is generally applied by opening a ring ditch. A vertical dripping line along the edge of the canopy was used to dig a circular groove of 20 cm to 30 cm in depth and 30 cm in width. Each tree was used to produce 40 kg to 50 kg of decomposed pig dung, 3 kg of superphosphate, and 1 kg of potassium chloride. To mix evenly, cover the soil immediately after application.
