摘要
以矮秆玉米嫩单8号为材料,研究不同群体密度对玉米各性状指标的影响。结果表明,群体密度对嫩单8号玉米株高、秃尖、百粒重等产量性状的影响均比较明显;群体密度6.6万株/hm2时产量最高,显著高于群体密度6.0万株/hm2的处理,其他处理间产量差异不显著;同时,对LAI和CGR也有一定的影响。
The relation between colonial density and character index of dwarf maize NENDAN No.8 was studied. The results showed that colonial density can affect yield properties of maize, such as height, bald point, 100-weight notably. The yield of maize was the maximal when the colonial density was 66 000(plant/hm^2). At the same time, colonial density also can affect LAI and CGR a certain extent.
