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0.63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。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 0.63 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.
