为研究先玉335的栽培种植技术,进行了种植密度试验。密度为4000株/667m~2,产量最高,风干粒质量为1075.01kg/667m~2。产量排在第2～4位的处理分别是密度为5000、3000和6000株/667m~2的处理。并且4个处理之间经过方差分析,处理2、3与处理1、4间差异达到极显著水平;随着密度的增加,株高和穗位增高,空秆率、茎折率和根倒率增加。综上所述,先玉米335的最佳种植密度应为4000～5000株/667m~2为宜。
In order to study the cultivation and cultivation techniques of Xian Yu 335, the planting density test was carried out. The density was 4000 / 667m ~ 2, the yield was the highest, and the dry weight was 1075.01kg / 667m ~ 2. The treatments ranked No. 2 to No. 4 were the treatments with densities of 5000, 3000 and 6000 plants / 667 m 2, respectively. And the variance of the four treatments was analyzed. The difference between the treatments 2 and 3 and the treatments 1 and 4 reached the extremely significant level. With the increase of the density, the plant height and ear position were increased, and the ratio of empty stalk, stem stalk, increase. In summary, the best planting density of corn 335 should be 4000 ~ 5000 / 667m ~ 2 is appropriate.
