How to manage jujube trees?

(1) Plastic film mulching can increase temperature and conserve moisture, and promote hair root growth. In the year of jujube planting, due to poor management, there is often a "suspended animation phenomenon" that delays germination. The masses call it "jujube trees will not germinate and die in those days". This phenomenon is mainly due to the drought and windy spring in the arid areas of northern China, which is easy to cause a lot of water loss of jujube trees. The solution is to fill enough water in time after planting, loosen the soil in time after water seeps into the soil, and then cover the tree tray with plastic film. This can not only effectively protect soil moisture, but also improve ground temperature and promote early rooting and rapid growth. Generally, each newly planted jujube tree is covered with a layer of plastic film 1 meter square.

(2) Making tree boundaries and creating protection lines. After planting, the border of the tree should be done in time, that is, ridging should be done from both sides along the jujube line. The width inside the border is 1 m, and the ridge is 30 cm wide and 20 cm high, which requires practicality. Doing a good job of ridging can not only facilitate the management of jujube trees, such as intertillage, watering, weeding, pest control and other field operations, but also protect young trees and effectively avoid the damage of agricultural machinery to young trees when working in the field. The tree bed is widened year by year with the increase of crown.

(3) Timely fertilizer and water management. In order to accelerate the growth of newly planted jujube trees, when the new shoots grow to 10 ~ 15 cm, combined with watering after rain or furrowing and topdressing, urea is generally applied to each plant at 0. 1 kg to ensure the nutrient requirements of the newly planted jujube trees. At the same time, attention should be paid to the prevention and control of pests and diseases of newly planted young trees, especially the prevention and control of jujube gall midge, yellow thorn moth, red spider and other pests. Combined with pest control, fertilizers such as urea or diammonium phosphate diluted by 300-500 times can be added for foliar spraying to promote the growth of young trees, generally for 3-4 times.

(4) Rational intercropping. Both jujube orchards planted in the form of jujube intercropping and pure jujube orchards can be planted in intercropping crops in the first year. In order to ensure the growth of young trees, intercropping plants must be short, preferably leguminous plants such as peanuts, soybeans and mung beans, and some melons and vegetables can also be intercropped to improve economic benefits. In this way, the fertilizer and water input in intercropping crops will also promote the growth of jujube trees. After planting, watering or raining, intertillage weeding should be carried out in time to ensure that young trees have a good growth environment.
