How to prevent freezing when pear trees bloom?

In flowering period, substances prepared with quicklime can be coated on the trunk of pear trees, with the height of1.5m. The trunk above the grafting site can be wrapped with thermal insulation materials under sufficient conditions, and can be smoked to prevent cold in low temperature environment. In addition, spraying 800 times new high-fat film at flowering stage can increase the cold resistance of stamens and increase the probability of fruit setting.

Anti-freezing method of pear flower 1, white trunk painting

How to prevent pear trees from freezing when they bloom during propagation? You can paint pear trees at warm noon. Take quicklime 10 kg, sulfur 1 kg, salt 0.2 cm, animal and vegetable oil 0. 1 kg, add clean water 30-40 kg, fully mix until it becomes a paste, and smear it along the center of the trunk to a height of/kloc-0.5 m from the bottom.

2, warm material package

In the case of sufficient conditions, the trunk above the grafting site and the three main branches at the base can be wrapped with warm materials, and in the case of insufficient materials, only the diseased plants can be wrapped to avoid freezing at flowering stage and affecting the quality of fruits.

Step 3 smoke

The snow around pear trees should be cleared in time. When the weather is cold, smoke can be generated in the pear garden, which has a great effect on freezing and keeping warm. Scraping old bark can be postponed until after the Spring Festival. When flowering, it can spray Zhuangguodiling to increase the resistance of flowers.

4. 800 times solution of new high-fat film

Spraying 800 times of new high-fat film solution during pear blossom. This solution can increase the cold resistance of stamens, reduce the harm of spring cold and improve the probability of fruit setting. You can also choose S- inducer, dilute 1500 ~ 2000 times with water, and spray 1 ~ 2 times evenly, which can alleviate frostbite.
