中稻再生稻与其它水稻一样,其亩产量也是由亩有效穗数、每穗实粒数和千粒重共同决定的,但在不同条件下,这三个产量构成因素对亩产量的贡献是不同的,其它农艺性状对这三个因素的影响也不一样。通过对它们进行相关分析和通径分析,可以了解它们对中稻再生稻亩产量的影响密切程度,为提出有效增产措施提供理论依据.作者于1987年下半年在环江县各乡镇对14块中稻再生稻田进行调查,将所得数据进行简单相关分
As for other rice varieties, the yield per mu is also determined by the number of effective panicles per panicle, the number of solid grains per panicle and the grain weight per thousand. However, under different conditions, the contribution of these three yield components to the production of mu is different, The effects of other agronomic traits on these three factors are also different. Through the correlation analysis and the path analysis of them, we can know their close influence on the yield per mu of middle-season rice and provide a theoretical basis for putting forward the effective measures to increase the yield .In the second half of 1987, Regeneration of rice fields to conduct a survey, the resulting data for a simple correlation points
