Jujube garden is the key to high-yield summer tube
Jujube trees are affected by the nutrient environment of the tree, and the flowers and fruits are very serious. Strengthening the summer management of the jujube garden is the key to increasing the yield of the jujube garden. Before blooming, the loose dense branches and erect long branches 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 stocks should be removed to reduce ineffective consumption, concentrate tree nutrients, increase the number of effective fruit-bearing stocks, and thus increase the fruit-setting rate. At the time of ring stripping, pay attention to "strengthening heavy trees, weak weak trees peel".
Watering jujube trees need sufficient water in the early stage of growth, especially in the flowering period and young fruit period, there is no shortage of water, and water should be poured twice according to weather conditions. 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 spraying 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. 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 from late May to mid-June, according to 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 advantage of jujube head growth, control Vegetative growth leads to 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 should pay attention to pest control from the flowering stage to the fruit expansion stage. 15% powder rust rather wettable powder 1000 times liquid can be used to prevent and control jujube rust, and 80% dichlorvos 1000 times liquid and 40% phoxim 1000 times liquid can be mixed and sprayed to prevent jujube inchworm, armyworm, peach worm.
