The new bagging technology of peach trees, bagging after the first month of flowering, late management is very important.

First of all, the bagging method of peach trees is best to choose a paper bag, which requires good permeability, adequate shading and water absorption, and should be evenly smeared with low toxicity and low residual fungicides that are harmless to the fruit. When bagging, the bottom of the paper bag should be stretched out first. Then carefully put in from the bottom of the young peach, the peach body can not be hurt, the fruit handle can not be broken, the young peach can be put into the center of the paper bag, and the young peach can not touch the paper bag. Note that each fruit should be bagged to prevent leakage.

First, bagging time

Peach trees are generally bagged after the first month after flowering, and the best bagging time is when peach trees enter the hard core stage when the second physiological fruit drop. The orchard needs to be thoroughly disinfected before bagging, and can be bagged when all the solution is air-dried. We can use methyl topiramate and other agents to disinfect, pay attention to foggy days can not be bagged, this is to prevent Rain Water erosion to make the liquid lose its effect.

Second, the benefits of bagging

Bagging helps to expand the fruit, increase the fruit yield, reasonable bagging helps to enhance the quality, make the pulp more fresh and delicious, and the fruit surface smooth and shiny. It is helpful to reduce the occurrence of fruit cracking in some easily cracked fruit varieties. Bagging also helps to reduce the incidence of various diseases and insect pests, such as peach borer, scab and so on.

Third, bagging method

1. Bagging choice

The choice of bagging is very important, and there are certain requirements for its materials. The permeability of plastic is very poor and can not be drained, so as to increase the rate of rotten fruit and the incidence of diseases. It is best to use a paper bag, which requires good permeability, low toxicity that is harmless to the fruit, sufficient light absorption and low residual fungicides.

2. How to cover the bag

When bagging, first stretch the bottom of the paper bag, and then carefully insert it from the bottom of the young peach, be careful not to hurt the young peach, otherwise the young peach can not continue to grow if it has a wound. Also need to pay attention to the handle can not be broken, the young peach carefully into the center of the paper bag, to prevent the young peach touching the paper bag, each fruit should be properly bagged to prevent leakage.

3. Take off the bag at the right time

Picking the bag at the right time can effectively improve the quality of the fruit, generally pick the bag twice, remove the outer bag of the paper bag about three weeks before the normal development of the fruit, and then remove the inner bag in a week or so. Be careful not to pick the bag on a sunny day, in case the fruit does not adapt to the sun and cause burns. After picking the bag, it is necessary to remove the shade leaves around the fruit, which is conducive to the coloring of the fruit tree and ensure the uniform color of the fruit.
