摘　　要：通过分析水稻开花灌浆期模拟阴天条件下，不同品种与不同栽培措施的水稻群体吸收光谱辐射能的差异，以及它们同水稻产量形成的关系，从而阐明在水稻生产实践中，结合当地水稻开花灌浆期的气候特点，选择受光条件好的水稻品种，实施合理的栽插密度与行株距，使用有效植物生长调节剂，是改善开花灌浆期阴天水稻群体内光质环境的重要途径。By analysis of the differences in the absorption radiant energies of different rice varieties with different cultural management under simulated cloudy conditions during flowering filling period, the relationship between light quality and yield formation were illustrated. The results indicate that the most important ways to improve the light quality within rice colonies in flowering filling period when the solar radiation is lack were as follows: combining the local climatic characteristics with practice in rice praduction, selection of suitable rice varieties with a good plant type, transplanting rice with a reasonable density and row space and properly using the effective plant growth regulators.
