At present, the Red Fuji apple bagging is a key measure for producing high-grade pollution-free green food, but a considerable number of fruit farmers have mastered the supporting management techniques of bad bagging, and the product production rate is very low, which affects the economic income. Since 1993, our town has promoted the application of new technologies for apple bagging. Since then, the majority of fruit growers have gradually explored the complementary management and technical measures to improve the quality of red Fuji apple bagging products. The results have been very good, and higher economic benefits have been achieved. Are introduced as follows: First, a reasonable plastic trim, improve lighting. In pruning, it is necessary to focus on solving problems such as too many backbone branches, large amount of invalid branches, excessive peripheral branches, and insufficient illumination. The auxiliary branches in the layers must be removed in the year to control the lateral growth, enhance longitudinal growth, extend branches of the lateral branches to cut the same age branches, control the back, remove the back, take the two sides as the main, and train the leaf-like and uniaxial extension results. Branches, to branch to see the light, leaves see the light. The amount of Muzhi after cutting is strictly controlled at 8-10 thousand pieces. Second, scientific fertilization and watering. High input can be highly effective, and the fertilization of the bagged Red Fuji apple orchard should be conducted according to the principle of “early basal fertilizer, good for topdressing, and timely application of foliar sprayingâ€. The basal application time is mid-to-late September. The basal fertilizer is preferably a pig manure, fermented chicken manure and cake fertilizer, and is mixed with an appropriate amount of N, P, and K fertilizers. In order to prevent the occurrence of physiological diseases of the fruit, appropriate amounts of trace element fertilizer such as calcium, magnesium, phosphorus, etc. should be added to the base fertilizer; the top dressing should focus on the cell division and fruit enlargement after flowering and fruit setting. In the early stage, N fertilizer was dominant, and 0.1-0.2 kg of urea was applied to each plant. P and K fertilizer were the main fertilizers in the later stage. Before bagging combined with insecticide bactericide spray 2-3 times ammoniacal calcium treasure 800 times liquid, single-spray 2 times active bio-organic fertilizer, in order to facilitate the increase of leaf photosynthesis, promote young fruit growth and development. On the water, focus on the three times before bagging, before bagging, and after bag removal to prevent sunburn and help with coloration and increase production. Third, choose a good quality fruit bag. The quality of the fruit bag directly affects the quality of the bagged fruit. Now that the fruit bag market is in disorder, fruit growers cannot blindly purchase. It must be based on whether they have national registered trademarks. The best fruit bags used in the region are Japan Kobayashi bags, Qingdao Ai Nong bags, and Longkou Kaixiang bags. Fourth, bagging management and bagging time. Red Fuji apples are best bagged for about 40 days after the flowers are cut. The best local time is June 15-30, and the best bagging time is 8-11 am and 2-5 pm in the day. 1. Strict fruit thinning. It is required that each fruit stand should be left alone, and those who are not correct, fruitful, and fruitful should all be neglected. The amount of fruit left per acre should be 1.2-1.4 million. 2. Conduct pest control 2-3 times. The bactericide is mainly composed of internal absorption, and it is preferred that 70% of imported thiophanate-methyl besides 800 times and that of 50% carbendazim be 600-fold; insecticides should be powder-based, and the preferred lingulin powder is 1200 times, and Wanling 1500-2000 times. Injection of domestic mancozeb, tetrobacter, Bordeaux fluid and other fungicides and EC insecticides to avoid causing hidden phytotoxicity, resulting in enlarged fruit spots, rough skin, chapped skin, fruit rust, dermal black spots Wait. The last drug before bagging should end 3 days before bagging. After the bagging, pest and disease control is mainly to protect the leaves. Fifth, the correct application of bagging technology. When the bag is bagged, the paper bag must be opened so that the paper bag is fully inflated and the corner bottom vent opens so that the fruit can be suspended in the center of the paper bag and the bag can be tightly closed. Be careful when handling. Six, coloring management and bagging and harvesting. 1. Go bag time. This area is generally around October 5, after a bag of 1-3 days should be sprayed again 10% Polaroid 1500 times or 1.5% multi-resistant 400 times 400 times antimycin, to prevent Alternaria solani infestation bagging fruit . Harvesting should be about 20 days after bag removal. Early fruit collection is easy to decolorize, and when it is too late, the peel appears rough and the color is dark. 2. Pick leaf and transfer fruit. The picking leaves of the bagged apple should be carried out 3-5 days after the bag is removed. The leaves that affect the light near the fruit should be removed and the amount of leaves taken should be 20%-30%. The transfer of fruit should be carried out about 7 days after bag removal. It is to transfer the fruit with the fruits on the fruit surface and the fruits that are supported by it. Turn fruit and gently turn the positive side of the fruit to the shade side. 3. Strengthen ground management. After bag removal, if the surface humidity is high, the water will affect the coloring of the fruit, and more strokes should be made to keep the surface soil dry. Then, those ineffective branches that are close to the ground and the back of the main branch should be removed to remove light. The condition of the orchard can be retroreflective film under the tree to increase the degree of fruit coloration.
