摘要： 分析了不同产量水平下，中浙优1号作单季晚稻栽培的穗、粒、重结构，利用相关、回归及通径分析的方法，研究提出了单季杂交晚稻中浙优1号高产高效栽培的技术途径：在一定的有效穗数的基础上，主攻每穗实粒数与千粒重。

Abstract: In different yield levels, the constitutions of panicle, grain and grain weight of Zhongzheyou 1, a single cropping late paddy, were analyzed. Methods of correlation analysis, regression analysis and path analysis were used to promote high-yielding and effective cultivation techniques as follows: besides necessary panicle amount, the direction is grain number per panicle and grain weight of one thousand grains.
