摘要：

研究不同遮荫条件下半夏的生长及增产效果。设SZW-8型、SZW-12型遮阳网遮荫及不遮荫3个处理，采用塑料钵进行试验，考察半夏鲜品产量、粒数、粒重和植株性状。SZW-8型、SZW-12型遮荫的半夏产量分别比不遮荫的降低0.73倍和1.82倍，其块茎粒数、粒重均低于不遮荫处理；随着遮荫率的增加，半夏株高、茎高增加，但叶长、叶宽与遮荫无关。在喀斯特温和气候区，半夏栽培以不遮荫为好。

Abstract:

The effects of different shading conditions on the growth and yield of Pinellia ternata were studied. The three treatments were the SZW-8 type shade net, the SZW-12-type shade net and the non-shading. The yield, grain number, weight and plant traits were investigated. The yield of SZB-8 type and HZW-12 type was 0.73 times, 1.82 times respectively lower than that of the non-shading. The grain number and weight were lower than that of non-shading. Plant height, stem height with the shade rate increased, but the leaf length, leaf width had nothing to do with shade rate. In the cool-temperate region of karst, no shading was the best condition for Pinellia ternata.
