Recently, some farmers asked the Fuji Apple what bag is better for the apple. Now we introduce a new bagging technology.
Red Fuji apples on the basis of the first cover film bag, the interval of 10 to 15 days, and then set the outer layer of gray or color paper, the inner layer of black paper double Apple special paper bag (ie double bag), the production of double sets The red Fuji apple bag is bright, clean, large, and has an excellent fruit rate of more than 90%. It not only overcomes the shortcomings of the rough surface of the single-layer membrane bag and the dullness of coloration, but also overcomes the problems of small bags of single-paper bags and easy removal of the bags. The shortcomings of red spotting and wrinkle skinning combine the advantages of a single set of membrane bags to increase fruit size and a single set of paper bags to promote coloration, which can improve fruit quality and efficiency. The key technologies of Red Fuji Apple's double set are as follows:
1. Do a good job of "five elections."
1 Choose a good garden. Choose orchards with neat gardens and high management levels, orchards with a light transmittance of about 30% during the growing season.
2 Choose a tree. Choose trees that are younger, grow stronger, and have better structures.
3 choose a good bit. Select the middle part of the crown, good light transmission, easy to grow large fruit, and good fruit.
4 choose good results. Select the fruit on the side and middle and long fruit branches that are straight and fruity, with a flat width on the fruit shoulder, a flat top on the fruit, a tight sepal, and sagging. Set of large fruit is not small fruit, set high pile fruit is not flat fruit, set end fruit is not set fruit pod oblique fruit, sets of no pests and diseases do not set the pest and disease fruit, set the central flower long handle fruit does not set short handle fruit and so on.
5 choose a good bag. Plastic bags use good-quality, high-reputation brand bags; paper bags are double-layer bags; outer bags are rain-resistant grey or white wax-colored paper bags; inner bags are high density, good light-blocking, and not black Paper bag.
2. Safe medication during bagging.
1 bagging 2 to 3 days before careful play a high-quality sterilization insecticide (supplemented calcium fertilizer) with fruit as the focus, the degree of atomization should be high.
2 During the period of bagging, spray the medicine once every 7 days. After spraying, spray heavy rain.
3 All germicides should be sprayed once after they are completely set.
4 before bagging insecticide fungicides should use microemulsions, soluble liquids, suspension agents, as far as possible not to use EC formulations, so as not to damage the fruit surface wax layer, induce fruit rust.
3. Early film bags, timely paper bags, timely removal bags.
General control of the Fuji Apples 15 to 20 days after the start of the film bag cover, before the end of June to complete the film bag, interval 10 to 15 days to start the paper bag, paper bag work completed by the end of June, in early October to remove the paper bag, and Timely picking leaves, fruit transfer, shop reflective film and other fruit coloration techniques.
4. Cultivate a good tree structure and robust tree vigor.
1 promote the application of quality tree, such as high light efficiency tree. To adjust the tree structure in a timely and scientific manner, as the age of the tree grows, the number of main branches should be gradually reduced, and the main trunk should be gradually improved; as a result, the branches and the result branches should be kept robust, droop naturally, and young.
2 Re-apply organic fertilizer to improve the orchard soil fertility, and apply high-quality chicken manure to 6 cubic meters per mu per year.
3 Focus on the prevention and control of “three diseases and two insectsâ€. Three diseases are rot, ring rot and brown spot; two insects are leaf miners, red and white spiders. We must use low-toxicity, pollution-free, and high-efficiency pesticides on the basis of forecasting and forecasting, and actively promote the use of uniform sprays throughout the park or village to increase the quality and effectiveness of sprays and ensure robust growth of branches, leaves, and roots for production. High-quality fruit creates a good tree condition. Http://Content/9f0306db-d64b-4cd6-a3da-b95ce4e3a104?cType=2
