不同光质配比的LED光源补光对水稻机插秧苗生长发育的影响
Effects of LED Light Supplementation with Different Light Quality Ratios on Growth and Development of the Machine-transplanted Rice Seedlings
摘要
Abstract
An experiment was conducted to evaluate the effects of LED light supplementation with varying red-blue light quality ratios on the growth and development of machine-transplanted rice seedlings,using Yongyou 12 and Yangliangyou 6 as experimental variety.During the seedling raising stage,blue LED light,red LED light,and red-blue LED light with a 50％ratio was used for light supplementation,with natural light was as the control.The results showed that LED light supplementation with different light quality ratios significantly influenced the growth of rice seedlings.Seedlings height was inhibited in blue LED light treatment,compactness and root-crown ratio of seedlings increased.Red light treatment led to a substantial elongation of the stems and leaf sheaths of rice seedlings,while promoting leaf senescence and hastening the growth process of seedlings.Furthermore,the leaf age of the two varieties of seedlings subjected to red-blue light treatment also exhibited a significant increase.The experimental results elucidated the effects of LED light supplementation on the morphology of rice seedlings,providing a scientific theoretical foundation and guidance for the regulation of the light environment in rice factory seedling cultivation.关键词
