- 摘要:
- 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12.24 t?hm -2,其次82 500株?h m -2,产量为12.16 t?hm -2, 对照密度60 000株?hm -2的产量最低,为10.05 t?hm -2,且90 000株?hm -2与60 000株?h m -2产量具有极显著差异。
- Abstract:
- 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 of 90 000 plants?hm -2 was the highest,reached 12.24 t?hm -2,followed by 82 500 plants?hm -2,yield was 12.16 t?hm -2.The yield of CK(60 000 plants?hm -2)was the lowest,reached 10.05 t?hm -2.And there was highly significant difference between 90 000 plants?hm -2and 60 000 plants?hm -2.
