Study on the Effects of Different Shading Treatments on Growth and Photosynthetic Characteristics of Young Tea Plants of Yellowing Variety Zhonghuang 3
摘要
Abstract
Taking young tea plants of the yellowing variety Zhonghuang 3 as the test subject,this study exploresd the effects of different shading treatments on their growth and photosynthetic characteristics,aiming to provide technical support for the cultivation of yellowing tea varieties.The results showed that shading treatment could significantly improve the survival rate of young yellowing tea plants and reduce the cost of seedling replacement in the later stage.Meanwhile,under shading treatment,the leaf area,new shoot diameter,new shoot length,branch number,new shoot weight,and new shoot moisture content of young tea plants all increased,and the new shoot length,new shoot weight,and new shoot moisture content under different shading treatments were significantly higher than those of the control group;Under shading treatment,the photosynthesis and transpiration of young tea plants of yellowing tea varieties were inhibited,and the water use efficiency was significantly improved,with a significant increase in stomatal conductance.Among them,young tea plants of yellowing tea varieties under 30%sunshade net shading treatment performed better in growth,with a survival rate increased by 41.74%compared to the non-shading treatment,the cost of seedling replacement per 667 m2 was reduced by 71.44%,and the new shoots grew most vigorously.This indicates that young tea plants of Zhonghuang 3 after transplanting,shading treatment with 30%sunshade net can significantly improve their survival rate,change their photosynthetic characteristics,and increase water use efficiency.关键词
