常规水稻品种黄华占栽培密度与产量的相关性研究

本试验研究了栽培密度对水稻黄华占产量及产量构成因素的影响,结果表明:栽培密度与有效穗呈显著正相关(r=0.932);与穗总粒数、穗实粒数、穗长、结实率均呈极显著负相关(r总=-0.996,r实=-0.997,r穗=-0.991,r结=-0.991);与千粒重呈显著负相关(r=-0.929);产量构成各因素间,穗总粒数与穗实粒数、穗长均呈极显著正相关(r实=0.997,r穗=0.998)。为夺得水稻黄华占高产水平,其适宜栽培密度处在Ⅲ与Ⅳ之间。

Relativity Research on Culture Density and Yield of Conventional Rice Variety Huanghuazhan

This experiment looks into the relativity of Rice Huanghuazhan culture density to its yield and yield components. The result shows that the culture density is significantly positively related to effective panicles(r=0.932), extremely significantly negatively related to total panicle amounts, effective seed amount, panicle length, and bearing percentage( respectively r=0.996,r=0.997,r=0.991, r=0.991), and significantly negatively related to the onethousandseed weight r=0.929). Among the yield component, the ...
