1. Watering fertilizer. Due to the early deciduous deciduous trees and fruiting late last year, the tree vigor was generally weak this year, and some of the jujube trees were seriously defoliated. Therefore, fertilizer and water must be added to supplement fertilizer. Fertilizer should be applied underground and fertilizer sprayed on the trees. Underground fertilization can be carried out in combination with watering. Generally, the results of each tree are 0.4-0.5 kg of diammonium phosphate and 1 kg of potassium sulfate. Foliar spray fertilizer can use urea solution, potassium dihydrogen phosphate solution, gold date solution. In the control of pests and diseases, the spraying of the fertilizer solution and the liquid mixture can not only save labor, but also have a synergistic effect on the pesticide.
2. Prevent fruit drop. Due to the weak tree vigor, the fruit has fallen due to inadequate nutrient supply. In order to reduce fruit drop, 20 ppm naphthylacetic acid can be sprayed on the canopy, sprayed once every 7 to 10 days, and sprayed for 2 to 3 times.
3. Pest control. In this period, pests are mostly green-lipped fox bugs, peach borer bugs, and red spiders. Special attention should be paid to prevention and control. If they are not controlled in time, they will cause fallen leaves and fruit drop. Can choose 25% Chlorocyanin Chlorpyrifos (Good Moroccan) EC 800 to 1000 times or 4.5% Betacypermethrin (Tianlongbao) Emulsion or water emulsion 1500 to 2000 times liquid, 1.8% Abamectin (rich farm) Emulsion 3000 to 4000 Times of liquid, 15% Dai Ling EC 1500 ~ 2000 times, spraying once every 5 to 7 days. The main diseases in this period include anthrax, date rust, fruit shrinking disease, brown spot disease, and rotenone disease. It can be used as follows: 30% dragon's lamp Fulian suspension agent 1000-1200 times solution, 50% thiophanate-methyl suspension agent 1000- 1200 times liquid, 800 times triazole copper, 77% donin 600 to 800 times, 1:2:200 times Bordeaux spray control. Afterwards, depending on the rainfall conditions, the rain will be more and more rainy, and the rain will be less and less. Generally, it will be sprayed every 7 to 10 days. Donin or Bordeaux blends work better with other fungicides. At the same time, spraying the fungicide should pay attention to the quality of the spray, to be crowned up and down, inside and outside, especially the back of the leaf to be sprayed, in order to improve the control effect of disease. In addition, jujube trees with severe iron deficiency are supplemented with iron, and 1,500 times more iron is added when spraying.
