| 摘 要： | 研究了不同纯度条件下沈农87品种玉米群体的田间性状及产量。结果表明:纯度与群体株高呈极显著正相关,处理间差异显著;随着纯度降低,株高整齐度下降,同一冠层高度透光率增加。产量与纯度为极显著正相关关系,纯度每降低1%,产量下降0.6%～0.7%。

| Abstract: | Plant height, light distributing and yield of different purity populations of maize were studied .The results showed that for Shennong 87, there was a significant positive correlation between plant height and purity, and the differences among the treatments were also significant. As the seed purity lowing, the degree of plant height regularity decreased, and the light transmittance increased at a given height in the canopy. There was a significant positive correlation between seed purity and yield, with seed purity descended by 1%, the yield loss of 0.6% - 0.7%, which was equivalent to about 70 kg/ha. |
