What to pay attention to before and after apple bagging
Apple bagging can significantly improve the quality of the fruit's appearance and commodities, and promote the bright color of the fruit. It is an advanced and practical technology for producing high-end commodity fruits and increasing the income of fruit farmers. Bagging in high-quality orchards can significantly promote fruit coloring, increase fruit surface finish, reduce pest damage, reduce hail and other mechanical damage, reduce pesticide pollution and residues, and increase the commodity value of fruits. However, according to what we have learned through many years of investigation, there are still many problems. Therefore, combined with the actual production, the fruit farmers are reminded of the “ten attentions†before and after bagging apples. What should I pay attention to before and after apple bagging? 1. Pay attention to spraying medicine before bagging and protect the blades. Bagging has the effect of preventing diseases and insects, but some diseases and insects have already infested the fruit before bagging. If they are not eliminated, the infested diseases and insects will continue to harm the fruit in the bag and lose the significance of bagging. During this period, regular spraying and fertilizer spraying must be carried out, which has a great effect on preventing and controlling diseases and insects, increasing fruit setting rate, increasing single fruit weight, and preventing deficiency. Second, pay attention to reasonable load. Strictly thin the fruit, leaving one fruit at 20-25 cm when setting the fruit, leaving the central fruit, the fruit with long fruit stalk, and thin the small fruit, apricot fruit, saki-shaped fruit, sky fruit, pest fruit, and wounded fruit. Third, pay attention to scientific supplementation. It is necessary to increase the amount of organic fertilizer applied. At the same time, pay attention to balanced fertilization, control nitrogen and increase phosphorus and potassium, especially in the middle and late stages of adding potassium and phosphate fertilizers, combined with spraying foliar fertilizer on the tree, which is beneficial to fruit coloring and anti-sunburn . Fourth, pay attention to standard technology. When the fruit is bagged, the operation technique is not standardized, which will result in a low rate of bagged fruit. The sealing should be strict when bagging, to prevent pests from entering the bag to propagate the harmful fruits, and to prevent the liquid medicine and rain from entering the bag to contaminate the fruit surface. When bagging, do not make the fruit bag close to the young fruit, so as to avoid rough fruit surface, fruit rust and sunburn. Fifth, pay attention to the damage caused by Kang's mealybug. Pseudococcidae gathers in the calyx recess to suck the fruit juice, causing small black spots, and it is mostly covered with white wax powder. It can also be penetrated into the bag through the air hole and the gap of the bag mouth. It occurs lightly within 1-2 years of the initial bagging of the orchard, but the insect fruit rate can reach more than 40% after bagging in successive years. Kang's mealybug. The mid-to-late May and mid-to-July are the peak periods of the first and second generation of nymphs respectively. In this case, timely prevention and control should be taken, and the bag mouth should be tightened when bagging. Sixth, pay attention to supplement calcium. In recent years, many nutrition experts have concluded that the effect of calcium on the quality of apples is far more important than that of elements such as nitrogen, phosphorus, potassium, and magnesium. Therefore, calcium plays a decisive role in the quality of bagged apples. Before and after bagging, the fruit trees should be sprayed with calcium fertilizer multiple times in combination with spraying to reduce the occurrence of bitter pox, water heart disease and other physiological diseases. Seven, pay attention to choose a fruit bag. The quality of the fruit bag depends on the quality of the bag and the manufacturing process. Choosing the correct bag and choosing the right bag are another key to the success of bagging. 8. Pay attention to the overall level of the orchard. The apples produced in high-end double-layer paper bags are brightly colored and the skin is delicate and the price is high. But not all orchards are suitable for high-end paper bags, which has a lot to do with site conditions and management level. An orchard with an altitude above 600 meters, high soil organic matter content, well-managed and robust trees should be selected, with high-end double-layer paper bags. For sub-optimal areas of apples, especially orchards where management cannot keep up and the pests are more harmful, in addition to strengthening management, it is suitable to set good quality single-layer bags or plastic film bags, which has low cost, large effect, and can also effectively improve The fruit commodity rate increases the economic benefits of the orchard. Nine, pay attention to supporting technology. Check the condition of the diseases and insect pests in the bag at any time; check the bandage of the bag in time; remove the yellow and squeezed leaves. Spray high-efficiency fungicide 1-2 days before bag picking to prevent the infection of fruits after bag picking by germs. After picking the bag, lay a silver reflective film in time to pick the leaves and turn the fruits in time. 10. Pay attention to timely and scientific harvesting. The order of fruit picking is up first, then down, then out. The skin of the bagged fruit is relatively thin and tender. During the process of harvesting and handling, it should be handled with care as much as possible to reduce bumps, pressure, thorns, scratches, etc. To be harvested and graded.
