| 摘 要： | 通过不同密度试验,得到合玉21密度与产量的回归方程,通过方程得出合玉21最高产量密度为6.42万株.hm-2,同时分析了不同密度对合玉21玉米商品品质的影响。结果表明:种植密度与收获时籽粒含水量呈正相关,与百粒重和籽粒容重呈负相关。

| Abstract: | Through the different density experiments,the mathematical model of yield and density of Heyu 21 was obtained,the maximum yield density was 64 200 plant·hm-2.At the same time,the effect on the commercial quality of Heyu 21 was analyzed,through the analysis,the water content of harvest kernel was showed positive correlation to planting density,and the weight of 100 kernels and volume weight were showed negative correlation to planting density. |
