How to prevent freezing injury of tea garden in cold weather in late spring?

The cold weather in late spring will cause freezing damage to tea trees. The main defensive measures are:

(1) Black sunshade net for the shed cover. Shading net covering can prevent snow and ice from entering the tea tree in late spring, thus increasing the temperature in the tea tree crown and preventing the sprouted shoots from freezing.

(2) Smoke anti-freezing method can also be used where the terrain is suitable. Listen to the weather forecast in time, master the anti-freezing time, detonate combustible materials when cold air comes, and smoke to prevent freezing.

(3) Tea buds that meet the tea picking standards should be picked quickly to reduce the loss caused by freezing injury.
