What are the antifreeze on the peach tree?

Spray with stone-sulfur mixture, or dilute the spray with oil emulsion mixed with dichlorvos and dimethoate EC. Spray paraffin 5 times emulsion, or 150 times carboxymethyl cellulose solution and other protective antifreeze. The plant can also be evenly sprayed 500-800 times with Happy Forest antifreeze.

1. Spray with stone-sulfur mixture, or dilute the spray with oil emulsion mixed with dichlorvos and dimethoate EC, so that the agent is uniformly attached to the leaves, which can not only prevent freezing, but also control insects.

2. Spraying protective antifreeze such as paraffin 5-fold emulsion or 150-fold carboxymethyl cellulose for 2 or 3 times before low temperature freezing injury can seal branch stomata, reduce water loss, prevent striping, delay fruit tree florescence and increase tree sap concentration. so as to enhance the cold resistance.

How to protect peach trees from freezing

Peach trees are easy to grow and flow gum, which affects the growth of fruit trees and the rate of fruit in the coming year. Huazhuawang No. 3 can completely eradicate the gummy disease, control the vigorous growth of strips, and improve the fruit setting rate. The measures such as bandaging the trunk and main branches of young trees and cultivating soil on root neck and white trunk and root neck of adult trees can prevent sunburn, freezing injury, diseases and insect pests. The trunk is bandaged and the root neck is cultivated. It is mostly used for young trees. The local period ends from the first and middle of October to the end of October. The material can be made of straw, waste agricultural film, straw rope, etc., to wrap the trunk and big branches tightly, with emphasis on the south side of the trunk and big branches, and then cultivate a small mound at the base of the trunk to protect the root neck and strengthen the binding. Remove the cold shield in the middle and late April of the following year. The trunk is painted white. It is mostly used in adult fruit trees. Trunk whitening can slow down the temperature upheaval caused by direct sunlight, prevent peach bark from freezing and xylem separation, kill some eggs and germs, and prevent livestock from eating tree trunks. The method is to use a brush dipped in whitening agent along the trunk, the main branch from top to bottom, from the inside to the outside in turn smear evenly. Whitening agent formula, 10 kg of quicklime plus 60 kg of water, plus an appropriate amount of stone sulfur mixture and a small amount of soybean powder or soybean oil. Clear orchards, no matter what kind of orchards, should be thoroughly cleaned after the beginning of winter, burning dead branches, fallen leaves, weeds or composting fertilizer, combined with winter pruning, removing dead buds, stiff fruits, paper bags, etc., thoroughly remove the habitat of overwintering diseases and insect pests. Skinning, preferably at the beginning of winter, should be mastered by light scraping of small and weak trees, only withered and warped skin; the principle of heavy scraping of big and prosperous trees to the slightly yellowish green of the cortex, and then smear the general lotion on the diseased spot to make the diseased spot dry and fall off quickly and remove the source of bacteria. Heat preservation and anti-freezing, in winter, we should pay attention to reduce frost damage and eliminate overwintering diseases and insects under the bark and cracks. After clearing the garden, the whole garden is sprayed to protect trees, disinfect and sterilize, keep warm and prevent frost, and protect the trees safely through the winter. For chemical control, peach trees had better spray targeted chemicals and new high-fat film twice after pruning and before and after sprouting.
