(1) before germination, trim, cultivate and adjust the skeleton structure to make the layout reasonable and ventilated. 1-4-year-old young trees are generally not sparse; More than 5 years old, treated with dense branches and long branches; In 7-8 years, the fruiting branches were updated in time, and the trees were not pulled out to open branches.

(2) Spraying 0.3-0.5 times of sulfur mixture to control red spiders and scale insects at the initial stage of seed germination.

(3) Trapping and killing adult jujube armyworm with black light.

(4) After germination, the inappropriate or redundant jujube heads should be erased in time.

⑤ Spraying 5% carbendazim EC 1000 times or 10% imidacloprid 4000-6000 times or chlorpyrifos 1500 times and mirex No.3 2000 times in the middle and late April to control jujube inchworm, red spider, jujube armyworm, jujube weevil and green.

⑥ In late April, phoxim particles were scattered in the tree tray within the range of 1m, and the unearthed date gall midge and date weevil were killed by shallow hoeing.

Planting management of winter jujube in different periods (branch-pulling and leaf-spreading period) in the first half of May

(1) In early May, spray 0% Caltex Diclofenac EC 99.65438+200-300 times (or 1000 times) to control jujube gall midge, red spider, gypsy moth, green blind stinkbug, jujube inchworm, etc.

② In the middle of May in the dry year, the jujube orchard was watered 1 time before flowering, diammonium phosphate 150-300g for young trees and 500- 1000g for fruit trees. For the vertically growing jujube tree head, the branch opening angle should be extended to improve the ventilation and light transmission conditions of the tree body, alleviate the growth potential and promote fruit setting.
