不同遮荫处理对林下半夏生长及光合特性的影响
Effects of Different Shading Treatments on Growth and Photosynthetic Characteristics of Pinellia ternata under Forest
摘要
Abstract
The effects of different canopy density on the growth and photosynthetic characteristics of Pinellia ternata were studied under three shading treatments.The results showed that under the shading treatment of plant row spacing as 1.0 m × 1.5 m with the canopy density of 57.4％,the Pinellia ternata plants grew faster,the leaves were larger and the number of leaves increased more.The photosynthetic rate of plants decreased with the increase of shading degree,and they were all lower than that of full light treatment.Comprehensive analysis showed that moderate shading could improve the growth rate of Pinellia ternata and improve the sprout tumble situation.The shading treatment with canopy density of 57.4％ could provide suitable environmental conditions for the growth and development of Pinellia ternata,which had important significance to improve Pinellia ternata total output.关键词
