选用碧香早和福大612个茶树品种作为试验对象,采用遮光率为(50±3)%的黑色、绿色和银白色遮阳网为遮光材料,以不遮光为对照,研究不同颜色遮阳网遮光对丘陵地区茶树产量指标和主要生化成分的影响。结果表明,春季不同茶树品种经遮光后可增加百芽重,但与对照间差异不显著;夏季碧香早和福大61经黑色遮光处理后百芽重均显著高于对照。 Sixty-two tea varieties of Bixiang early and Fu Tai were selected as test objects. Black, green and silver shades with shading rate of (50 ± 3)% were used as shading materials to study shading with different shading colors Effect on Yield Index and Main Biochemical Components of Tea Tree in Hilly Region. The results showed that in the spring, the photosynthetic rate of different tea varieties increased after shading, but the difference was not significant with the control. In summer, the photosynthetic rate of buds of Bixiang early and Fuda 61 were significantly higher than those of the control after being shaded by black shading.
