摘要
运用水稻叶龄模式群体基本苗计算公式 ,对黄淮地区优质水稻圣稻 30 1的群体密度与产量形成及品质关系进行的分析表明 :依照公式计算的标准密度群体不仅在产量形成、个群体生产力、生长动态及抗倒伏性能等方面均表现了较好的综合优势 ,同时在米质性状上也保持较好的协调关系 ,由此初步明确与公式运用相关的参数 。
By applying the formula of basic-seedling quantities in Leaf-age Model,the relationship between population density and yield formation and grain qualities in the good-quality japonica,Shendao 301,was studied.Results showed that the expected-density population according to formula took on general advantages in yield formation,productivity of individuality and population,growth grocess,lodging resistance,and grain quality.As a result of these,the parameters in relation to applying formula were defined.Moreover,the technique of applying basic-seedling of rice aiming at good-quality and high-yield cultivation in Huang-Huai region was put forward.
