Thinning. Before flowering, the dense branches and erect long branches in the bore should be removed in time to improve the spatial distribution of the fruiting branches and the ventilation and light transmission conditions of the tree body, and improve the photosynthetic efficiency. During the ring stripping period, the weak and empty hanging on the jujube tree should be removed to reduce the invalid consumption, concentrate the tree nutrition, increase the number of effective fruit-bearing units, and thus increase the fruit-setting rate. Strip lightly." Watering. The jujube tree needs sufficient water in the early stage of growth, especially in the flowering stage and the young fruit stage, it should not be short of water. It should be poured twice according to the weather. Watering during flowering can increase air humidity, which is beneficial to pollination and insemination and improve fruit setting rate; watering during young fruit can prevent fruit shedding and promote the growth of young fruit. Foliar spray fertilizer. Foliar spraying can make up for the nutritional deficiencies of jujube trees in time and meet the nutrient requirements of jujube trees for flowering and fruit setting. It is a cost-effective fertilizer application method. Fertilizer spraying time is generally selected in the bud period of jujube trees in early May, the final flowering period in mid-June and the rapid growth period of pulp in mid-July. Spraying the mixture with 0.5% urea and 0.1% potassium dihydrogen phosphate has the best effect. Topping out. From late May to mid-June, depending on the strength of the growing new jujube head and the size of the space, leave 3 to 5 secondary branches for topping, except for the backbone extension branches, remove the top edge of the jujube head growth, and control nutrition Growth, direct the distribution of nutrients to reproductive growth, so that flowering and young fruit growth get relatively more nutrients and reduce falling flowers and fruits. Pest control. At the flowering stage to the fruit expansion stage, attention should be paid to the prevention of diseases and insect pests. It can be used to prevent and control jujube rust disease with 15% of powder rust rather than 1000 times of wettable powder, and mixed spraying with 80% of dichlorvos 1000 times and 40% of phoxim 1000 times to prevent and control jujube inchworm, slimy worm, peach borer, etc. Disclaimer: Some articles of this website are transferred from the Internet.
