对塑料大棚覆盖茶园的应用研究结果表明 ,覆盖期间≥ 1 0℃有效积温增加 45 0 .9℃ ,从而使茶叶开采期较露天茶园提早 2 0～ 2 5天 ,6 6 7m2 春茶总产值达 70 1 8.5元 ,纯收益达3840 .75元 ,分别高出露天茶园 4.7和 4.8倍 ,经济效益十分显著
The results of the application of plastic greenhouses covering tea plantations show that during the period of covering, the effective accumulated temperature of ≥10 ℃ increased by 45.9 ℃, so that the tea production period was 20 ~ 25 days earlier than the open tea plantation, and the total output value of 667m2 spring tea reached 70 1 8.5 yuan, net income of 3840.75 yuan, respectively, higher than open-air tea garden 4.7 and 4.8 times, the economic efficiency is very significant
