Abstract:

Mulching treatments on the tea plantation in the plastic green house could decrease the maximum temperature and increase the minimum temperature. And they reduced the D-value of the maximum and minimum temperature obviously. They were effective on protecting the tea shoots out of the frostbite. Non-woven fabric mulching was the best among all the treatments, which tea trees grew fast after freezing, not only the yield was the highest, but also the production value and economic benefit.
