First, the main white In the early spring, the main white coating can slow down the temperature of the tree body, reduce the freezing damage, delay the germination and flowering of the fruit trees, effectively avoid the early spring frost damage, and also cure the tree diseases and insect pests. Second, irrigation In the case of drought, the watering of the fruit trees before germination can delay the flowering period of 2-3 days; after germination, the watering can be postponed for 3-5 days; before the low temperature frost, take the intermittent spraying of the fruit trees for two minutes and stop for two minutes. The water method can delay the flowering period by more than 10 days. Third, fumigation When the nighttime temperature drops to 0 °C, igniting smoke in the orchard can effectively reduce the freezing damage. 4-6 smoke piles should be placed in each acre orchard. Fourth, spraying 2-3 days before the flowering and germination of the fruit trees, spraying the plant cold-resistant agent on the tree body can prevent freezing damage, that is, spraying low-concentration aqueous solutions such as ethephon or naphthaleneacetic acid and chlorophyll can inhibit flower bud germination and improve cold resistance. For flowering fruit trees, phosphorus or potassium fertilizer or 0.3-0.6% potassium dihydrogen phosphate aqueous solution may be sprayed on the fruit trees before the occurrence of low temperature freezing damage to enhance the cold resistance of the fruit trees and reduce the freezing and freezing of flowers. Fifth, the application of antifreeze Sunshine brand fruit tree flower bud antifreeze can effectively solve the freezing damage caused by the constant low temperature of vegetables, fruit tree flower buds and various crops in the late autumn and early spring. The agent also has the effect of promoting growth and increasing the fruit setting rate, and is a green medicine which is non-toxic, non-polluting to the human and animal, and has no phytotoxicity. The agent contains substances, long-termening agents and various nutrients for improving the cold resistance of crops. After being absorbed by the crops, the agent not only improves the cold-resistant and anti-freezing ability of the crops, but also promotes growth. Anti-freezing agent for fruit tree flower buds is suitable for all kinds of fruit trees, tea, mulberry, strawberry and various flower and fruit seedlings, and has anti-freezing effect on flower buds, buds, leaves and young fruits of fruit trees. In the early spring, the flower buds of the fruit trees can be sprayed after they start to expand, and the antifreeze effect can be exerted about 4 hours after spraying. Spraying once will prevent the fruit tree flower buds from freezing damage at minus 3-4 °C and lasting for 7-10 days. The antifreeze for vegetables is 5-10 kg per 100 g of water, and the antifreeze for fruit trees is 15-25 kg per 100 g of water.
