皋兰县特用玉米密度试验

Density Experiments of Special Maize in Gaolan County

为了解特用玉米的种植密度与产量及产量构成因素之间的关系,筛选出合理的种植密度,进行了6组密度试验。结果表明:密度为90 000株·hm^(-2)的产量最高,为12.24t·hm^(-2),其次82 500株·h m^(-2),产量为12.16t·hm^(-2),对照密度60 000株·hm^(-2)的产量最低,为10.05t·hm^(-2),且90 000株·hm^(-2)与60 000株·h m^(-2)产量具有极显著差异。

To investigate the relationships among the planting density,yield and its component factors of special maize,density experiments were conducted for selecting the reasonable planting density.The results showed that the yield of90000plants·hm2was the highest,reached12.24t·hm2,followed by82500plants·hm2,yield was12.16t·hm2.The yield of CK(60000plants·hm2)was the lowest,reached10.05t·hm2.And there was highly significant difference between90000plants·hm2and60000plants·hm2.
