How to manage pomegranate trees?

How to manage pomegranate trees? How to manage pomegranate trees to achieve high yield? Also ask experienced netizens to introduce in detail that pomegranate is a kind of berry, which is rich in nutrition and vitamin C is one to two times higher than apples and pears. And pomegranate contains a lot of organic acids, sugars, proteins, fats, vitamins and minerals such as calcium, phosphorus, potassium and so on. Thus widely planted in China, so the planting network sorted out the pomegranate tree fertilizer and water, pruning, diseases and insect pests and flowering management methods, listed below in detail for netizens' reference. 1. The methods of fertilizer and water management of pomegranate trees: 1. The principle of fertilization for pomegranate trees is mainly organic fertilizer, supplemented by chemical fertilizer, and the fertilizer should not have adverse effects on orchard environment and fruit quality. Fertilization method and quantity of pomegranate trees: the basic fertilizer of pomegranate trees is generally applied after fruit harvest in autumn to before defoliation, mainly farm manure, mixed with a small amount of nitrogen fertilizer. The topdressing of pomegranate trees needs to be carried out three times a year, the first time from budding to budding stage, the second time in the young fruit expansion stage, the third time in the fruit color conversion period, and the last topdressing amount is very small, but it can be ignored; foliar fertilizer spraying is carried out 4 times a year, generally 2 times in the early growth stage and 3 times in the later stage, which can supplement the trace elements needed for the growth and development of fruit trees. In addition, spraying Zhuangtiling once before flowering, young fruit stage and fruit expansion stage of pomegranate can supplement the nutrient consumption of trees, protect flowers and fruits, and improve the rate of fruit setting. 2. Moisture management of pomegranate trees: pay attention to drainage in the rainy season, irrigation is needed in the dry season, and the winter water supply with off-season fruit is especially important, usually irrigating once every 10 to 15 days. Frozen water is irrigated in winter, and the back border can be covered with plastic film to keep warm and moisturizing. Second, the pruning method of the pomegranate tree: because the pomegranate tree is a light-loving tree species, the branches in the crown should be sparse and dense, so that both inside and outside can achieve ventilation and transparent results. 1. Pomegranate tree pruning method in summer: ring peeling method: it is mainly used for strong branches on young and prosperous pomegranate trees. 0.3cm girdling of smooth parts of strong branches according to width in the middle and first ten days of June can obviously promote flower bud differentiation and formation and improve fruit setting rate. Coring method: when the top shoot of pomegranate tree is 5cm or when the new shoot grows to 30~40cm, it can promote flower bud differentiation and fruit development, and increase the fruit setting rate. De-germination method: the new branches germinated below the 50cm of the trunk were generally cut off from July to August to facilitate the growth of the upper part of the trunk and reduce the loss of nutrients. 2. Pomegranate tree pruning method in autumn: thinning branches: continue to cut off dense, overgrown, diseased and insect sprouting branches and tillers. After branch thinning, the light spot under the crown is required to be evenly distributed on the ground, accounting for 10% to 15% of the projected area of the total crown. Ensure that the fruit can see the light directly, so that the inner chamber leaf branches and short branches can see enough light, and the flower bud can be formed quickly. The cut fruit branches of diseases and insects should be deeply buried or burned. 3. Pomegranate tree pruning methods in winter: pomegranate trees are generally not pruned in winter, but only withered branches, disease and insect branches are cut off. Third, the management methods of pomegranate tree flowering and fruiting stage: 1. Control shoot and promote flower: generally, cut and smear Huawangwang No. 2 on the trunk or main branch and large auxiliary branches of pomegranate tree before flowering (early May) to improve the fruit setting rate. The vigorous shoots on the back were wiped off many times in the flowering and young fruit stage to increase the fruit setting rate and reduce the drop of flowers and fruits. 2. The method of flower thinning and fruit thinning of pomegranate trees: the pomegranate has a large number of flowers, so it should be thinned in time, the earlier the better, and the complete flowers of the third stubble are generally thinned. Thinning every 10 days from identifiable flowers. Fruit thinning method: fruit thinning adopts the method of keeping more flowers and fruits, leaving fruit twice and thinning fruit three times, so that the pomegranate tree can be planted in a reasonable way. Fourth, pomegranate disease control methods: the main diseases of pomegranate are scab, dry rot, early deciduous disease, pomegranate pests include aphids, scales, peach bark borer, leaf mites, etc., using natural enemies or spraying imidacloprid, aldicarb, carbendazuron 3, avermectin, boll urea, Taoxiaoling and other insecticides to remove the branches and fruits of diseases and pests at any time. Then spray tree protection general disinfection and sterilization to prevent the spread of germs and spray appropriate amounts of insecticides for prevention and control. The new high fat film microfilm bagging can automatically spread and wrap the fruit by evenly spraying the fruit surface, which not only has a good control effect on a variety of fungal diseases, but also isolates high pesticide residues, increases coloring beauty, and produces pollution-free fruit.
