| 摘 要： | 为研究中农大甜413的栽培种植技术,进行了种植密度试验。结果表明:种植密度为4500株/667m2的产量最高,其商品穗质量为749.5kg/667m2,鲜穗质量为830.5kg/667m2,鲜籽粒质量为538.1kg/667m2,产量居第2～3位的分别是密度为5000、5500株/667m2的处理,3个处理之间方差分析差异不显著;产量居第4～6位的分别是密度为4000、3500、3000株/667m2,3个处理之间方差分析差异均达显著水平;产量居第4～6位的3个处理与第2～3位的3个处理之间差异达到极显著水平。同时,随着密度的增加秃尖长度加长、倒伏率提高。综合考虑,中农大甜413的种植密度以4000～4500株/667m2为宜。 |

| Abstract: | In order to study cultural practice of Zhongnongdatian 413, this paper was focused on test of different planting density. The results were showed that the highest yield was in density of 4 500 plant per 667 m2, commodity ear weight was 749.5 kg per 667 m2, fresh ear weight was 830.5 kg per 667 m2, fresh grain weight was 538.1 kg per 667 m2, the second and three yield of the density was respectively 5 000、5 500 plan per 667 m2, 3 dealing with differences between the party’s analysis had no significant differences. The fourth and sixth yield of the density was respectively 4 000、 3 500、 3 000 plan per 667 m2, 3 dealing with differences between the party’s analysis had significant differences. The first 3 processing and afer 3 processing had significant differences level. Meanwhile, with the sharp increase in density of length, longer lodging rate had increased. Comprehensive consideration, the optimum density of Zhongnongdatian 413 was from 4 000 to 4 500 per 667 m2. |
