What are the hazards of preventing late frost and its remedial measures during the flowering period of cherry blossoms?

Early cherry blossoms are very vulnerable to spring frost attacks and cause frost damage during flowering. It has been observed that weak trees are weighed heavily, and strong trees are lightly frozen; natural open heart is frozen and spindles are lighter; young age The pods and the lower young fruits in the tree are frozen and the young fruit in the upper part of the tree is lightly frozen. Frost is the most widely used method when frost comes. High-quality orchards can increase the temperature by about 2°C. Smoke method: smoke at least 5-6 piles per acre, evenly distributed in all directions. The grass pile is 1.5m high and the bottom diameter is 1.5-1.7m. When the grass is piled in, a few thick wooden sticks are inserted obliquely. After the raft is pulled out, it is used as a vent hole. The flammable material is placed inside the haystack by the hole. The outside is covered with a layer of wet grass or wet mud, so that the amount of smoke is sufficient and lasts for a long time; ammonium nitrate can also be ground and refined with 2.5 parts of ammonium nitrate, 1 part of waste diesel oil and 6.5 parts of sawdust homemade smoke. Sawdust is evenly mixed and lighted in a drum. Strengthening the management of the tree, watering the flowering stage, laying the grass on the ground, spraying the antifreeze twice 800-1000 times before the flowering on the tree also have a certain effect.

After being frozen, the orchard should promptly rake loose soil to prevent soil compaction and increase the ventilation of the soil so as to facilitate the growth of the root system. 1000 to 2000 times of the transplanting spirit can be used for irrigation. Foliar spray 1 or 2 times (5 to 7 days apart) 200 times sucrose + 600 to 800 times antifreeze + 30 to 40 mg/liter gibberellin + fungicide to restore the tree vigor. The growth of the new shoots is controlled by spraying 100 to 300 times of PBOs on the growing season.
