对 2 1块新香优 80早稻示范田随机取样 ,进行产量及构成因子统计分析 ,结果表明 :构成产量的 4个因子与产量均呈正相关 ,有效穗、穗粒数、结实率与产量之间呈极显著相关 ,粒重与产量之间为显著相关。各因子之间又相互制约 ,千粒重分别与有效穗、穗粒数、结实率之间呈显著负相关 ,其余都达极显著负相关。田间栽培管理必须促进产量构成各因素协调发展 ,才能获得高产。

The results showed that there was a positive correlation between the four factors that make up the yield and the yield, and there was a significant positive correlation between the yield and the effective spikes, grains per spike, seed setting rate and yield There was a significant correlation between grain weight and grain yield. There was a significant negative correlation between each factor and the other factors. There was a significant negative correlation between 1000-grain weight and effective panicle, grains per spike and seed setting rate. Field cultivation and management must promote the coordinated development of the various factors that make up the output and achieve high yield.
