Abstract
[ Objective ] To study the effect of winter LED supplementary illumination on growing development of Taxus chinensis var. mairei Cheng et L. K. [ Method] The effect of winter LED supplementary illumination on growing development of T. chinensis in winter was studied by setting different intensity of supplementary illumination, including 1 000,3 000,5 000, and 7 000 lx ). [ Result ] The condition of 3 000 - 7 000 lx LED supplementary illumination could promote the growth of T. chinensis while the condition of below 1000 lx had little effects on its growth. And once the supplementary illumination was more than 5 000 lx,the effects got smaller. What' s more,only about 126 lx under LED plant growing lamp,the T. chinensis could bring the same net photosynthetic rale that under the condition of natural light (1 257 lx). [Conclusion] LED plant growth light is a kind of new light source that can bring higher net photosynthetic rate for plants at lower transpiration rate.关键词
