栽培密度对大豆产量和品质性状影响的研究结果表明 ,生物重和籽粒重在不同密度间均存在显著差异 ,蛋白质和脂肪含量在不同的栽培密度下有一定程度的差异 ,但未达到显著水平。籽粒重随密度 (在供试的密度范围内 )的增加而提高。在 14 .5万株 /hm2 栽培时 ,生物重达最高 ,籽粒重和脂肪含量在 15 .75万株 /hm2 时达最高 ,蛋白质含量在 12 .2 5万株 /hm2 栽培时达最高
The results of the study on the effects of planting density on soybean yield and quality traits showed that there were significant differences in biomass and grain weight among different densities. The protein and fat contents differed to some extent under different planting densities but did not reach significant levels. Grain weight increased with increasing density (within tested density range). The biomass was the highest at 145,000 plants / hm2 cultivation, with the highest grain weight and fat content at 157500 plants / hm2. The protein content reached the highest at 12500 plants / hm2 cultivation
