Spraying Boron during the flowering period and spraying borax solution during flowering period can promote pollen germination and pollen tube elongation, which can facilitate the completion of the fertilization process and achieve the purpose of improving the fruit setting rate. When spraying, sunny and windless weather should be selected. The quantity of spray applied is the degree of leaf dripping, spraying 2~3 times, separated by 5~7 days. Can also be combined with foliar spray fertilizer. Jujube hanging picking heart in early June, the second branch to stay 3 to 7 sections for picking the heart; jujube hanging picking heart in late June. The earlier the picking, the better the effect of flower protection and fruit preservation. The main stem and branches are cut into rings of 3 to 8 for each date, and girdling or ring cutting is performed. Generally, the girdling width is 1/10 of the dry diameter, and the width should not exceed 1 cm in the widest range. Large trees and strong trees can be appropriately widened, and small trees and weak trees should be narrowly girdled. In general, jujube trees can only be girded once a year, and individual trees can be peeled off twice. The jujube garden puts the bee under normal circumstances, the jujube flower needs to pollinate the result. During the flowering period, the bees are placed in the jujube garden to increase the pollen transmission medium and improve the pollination probability of jujube flowers, thereby increasing the fruit setting rate. Drought water spray in general jujube flower season is a dry season, so take artificial water spray method to increase air humidity. The water spray time is better after 5 pm, as long as possible to delay the water evaporation time of the canopy. When the flower is open nearly 50%, spray water or add 0.3% urea in the evening to facilitate flower protection. Rational fertilization From late June to early July, the young tree plants were treated with diammonium phosphate and 500 g of potassium sulfate. The resulting tree was doubled, combined with fertilization and pouring water to promote fruit and water. After watering, the jujube garden spreads 20 to 25 cm thick wheat straw or weeds. The grass is covered with soil to prevent wind blows. Prevention of Pests and Diseases Spraying Streptomycin for agricultural use or avermectin for control of fruit nectar, bacterial scab, anthrax, jujube leaf spot, borer, red spider, etc. In late June, artificially caught scarabs, macular mites, jujube buds and other pests. Jujube anthracnose is generally heavier from mid-July to mid-August. The germs are transmitted by dew and wind and rain. If the rain is more diligent in June, the disease usually starts from late June, and organic fertilizer, flowering time and young fruit can be added. Fertilizer can be sprayed on the leaves. From late June to early July, the seeds were sprayed to prevent and control juvenile armyworm, peach, cotton bollworm, beet armyworm, red spider, macular mite, ring rot disease, rust, and jujube leaf spot disease.
