| 摘 要： | 以8个不同株型玉米品种为试验材料,进行不同密度与玉米生长发育及品质相关性研究。结果表明,不同密度影响玉米最高叶面积指数,同时,由于密度不同,各性状也发生变化,密度与玉米株高、穗位呈正相关,与茎粗呈负相关;与蛋白质、脂肪含量呈负相关,与淀粉含量呈正相关。平展型密度为4.5万株/hm2、中间型为5.5万株/hm2、紧凑型为6万株/hm2的情况下比较适宜。

| Abstract: | The correlation between plant density and growth and quality was studied using 8 different plant-type varieties of maize.The results showed that plant density influenced the maximum LAI maize.The plant height and ear height was positively correlated with plant density,while the stem girth was negatively correlated with plant density.The protein and fat content was negatively correlated with plant density,while starch content was positively correlated with plant density.The results suggested that proper plant density was 45 000,50 000 and 60 000 plants per hectare for plane leaf-type varieties,middle leaf-type varieties and tight leaf-type varieties respectively. |
