摘要:

以甬优12和扬两优6号作为试验材料,育秧期间采用纯蓝LED光源、纯红LED光源及红蓝光质各50%配比光源补光,以自然光下育秧为对照,研究不同红蓝光质配比LED光源补光对水稻机插秧苗生长发育的影响。结果表明,不同光质配比的LED光源补光对水稻秧苗生长有显著影响。蓝光能够抑制幼苗株高,提高充实度和根冠比,在培育壮苗方面发挥重要作用。红光处理下的水稻幼苗茎和叶鞘显著伸长,秧苗生长进程加快。此外,参试2个品种经红蓝光处理后的幼苗叶龄显著提高。试验结果探明了使用LED补光处理对水稻幼苗形态的影响,为调控水稻工厂化育秧的光环境提供了科学依据。

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.
