How to manage pomegranate trees before picking?
How to manage pomegranate trees before picking? What should I pay attention to before picking pomegranate? Also ask experienced netizens to help introduce that general pomegranate growers often do not manage pomegranate trees before picking, so the quality of some pomegranate fruits is poor, so the planting network has sorted out some key points of management of pomegranate trees before picking. The following detailed list is for netizens' reference. Point 1. Remove the overgrown branches, erect branches, dense branches and slender branches from the inner chamber of the crown. Keep the inside of the crown ventilated and transparent. The exuberant shoots that have not stopped growing but need to be preserved for the purpose of cultivating tree shape are gently plucked to reduce nutrient consumption, make branches grow fully and healthily, and ensure safe overwintering. Point 2. Bagging fruits should be bagged in time from late August to early September, and the bagging time is 20-25 days before harvest. Bagging is most beneficial to fruit coloring and sugar content improvement. Bag removal should be carried out after 4 pm on cloudy or sunny days. If you are covering a double bag, remove the outer bag first and go to the inner bag after an interval of 3 to 5 days. To remove the bag, you should pay attention to the weather and beware of pericarp burns caused by high temperature and strong sunlight, reducing the value of the fruit. After removing the bag, the fruit colorant should be sprayed in time to promote fruit coloring. Picking leaves and turning fruits is an auxiliary measure to promote pomegranate coloring. When picking leaves, remove the bag, remove the leaves that block the direct sunlight of the fruit, and remove the twigs that block the fruit. Turn the fruit so that the shady side of the fruit can be seen to ensure that the whole fruit is colored evenly. The pedicels in some parts of the fruit are short and thick and cannot be rotated. By means of pulling, distinguishing and hanging, the position of the fruit mother branch can be turned so that the back of the fruit can be seen and colored. Laying reflective film is also an important measure to promote pomegranate coloring. From early September to before fruit harvest, applying silver reflective film under the pomegranate tree or in the tree row can obviously improve the light intensity of the inner chamber and middle and lower part of the crown, and increase the coloring area and quality of the fruit. Third, 10-15 days before pomegranate harvest, watering should be strictly controlled, especially irregularly irrigated orchards in dry mountains, hills and plains, and should be harvested in time after prolonged drought and rain. Spraying 25 mg / L gibberellin in late August and early September can reduce fruit cracking by more than 30%. Point 4. Generally, pomegranate bears a large amount of fruit, or the soil does not supply enough fertilizer, and the harm of diseases and insect pests is serious, which can easily lead to premature senescence, while the middle and late September is the second peak of flower bud differentiation of pomegranate trees in the same year, and flower bud differentiation in this period directly affects the yield of the second year. Therefore, it is important to take measures to promote the healthy growth of the tree. It is necessary to apply quick-acting fertilizer in time, pay attention to the combination of nitrogen and phosphorus, apply potassium appropriately, apply 0.25 kg of urea and calcium superphosphate each, and spray 0.2%-0.35% organic potassium fertilizer or multi-element micro-fertilizer on the leaf. Point 5. Pomegranate trees should be "promoted before and after control" in fertilizer and water management, which should not only ensure the normal growth of pomegranate trees, but also prevent them from growing in the later stage. Therefore, nitrogen fertilizer is the main fertilizer in the early stage, with phosphorus and potassium fertilizer, timely and appropriate irrigation, while in the later stage, phosphorus and potassium fertilizer is the main fertilizer to reduce the number of irrigation. For prosperous pomegranate trees, 40% ethephon 2000-3000 times can be sprayed after fruit harvest to regulate tree growth. During this period, pomegranate trees mainly control diseases and insect pests such as peach borer, peach heart borer, stem window moth, diamondback moth, Chinese golden belt moth, golden caterpillar, dry rot, fruit rot, brown spot and other diseases. The control methods are as follows: cut the insect tip, pick the insect fruit, bury or burn it deeply, and kill the pupated larvae on the trunk; spray 40% mancozeb 500x solution or 40% methyl thiophanate 800x solution or 40% carbendazim gum suspension 500x solution plus 50% crystal trichlorfon 1000 times solution to prevent and control pests. The use of toxic pesticides should be reduced as much as possible in the later stage.
