通过对早稻抛秧产量诸因子进行生统分析，结果表明：构成早稻抛秧产量的四个主要因子中，除结实率呈微弱的负相关外，其余三因子均有正向作用。四个产量因子是相互制约、相互统一的整体。其中亩有效穗数对产量的贡献最大，每穗粒数次之，结实率居第三，千粒重最小。栽培上，首先应保证有足够的亩有效穗数的基础上，力争增加每穗粒数，提高结实率和千粒重。 Through the analysis of the conventional factors of the yield of early rice throwing, the results showed that among the four main factors that constitute the output of early rice throwing, all the three factors have a positive effect, except that the seed setting rate is a weak negative correlation. The four production factors are mutually constrained and mutually unified. Among them, the effective panicles per acre had the greatest contribution to the yield. The number of panicle per panicle was the third, the grain weight was the smallest. Cultivation, the first should ensure that there are enough acres of effective panicles on the basis of, and strive to increase grain number per spike, improve seed setting and grain weight.
