摘要
研究了不同纯度条件下郑单958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%。
The field properties and output of Zhengdan 958 in different purity conditions were studied.The results showed that correlation between purity and height was highly significant positive;with purity decreasing,height uniformity declined and transmittance of the same high degree increased.The correlation between output and purity was very significant positive,with the purity decreasing by 1%,the output decreased from 0.6% to 0.7%.
