采用不同地号,相同种植条件的绥玉7进行抽样调查分析,探讨绥玉7在不同的栽培密度下,各产量性状的变化情况。结果表明,密度对绥玉7玉米株高、百粒重等产量性状的影响均比较明显。密度增加株高先增加后下降。密度4669株/亩时,亩产最高,与密度4335时的亩产差异不显著,但显著高于其它种植密度的亩产。
Suiyu 7 with different ground number and same planting conditions was sampled and analyzed to investigate the changes of yield traits of Suiyu 7 at different planting densities. The results showed that the density of Suiyu 7 maize plant height, 100-weight and other yield traits are more obvious. Increased density increased first and then decreased. When the density is 4669 trees / mu, the highest yield per mu is, but no significant difference with the density of 4335 mu, but significantly higher than that of other planting density.
