摘要：

为了探讨‘衡星401’在江西稻田的生态适应性，2011年通过设置不同播期来观测玉米的产量和植株特性。试验结果表明：玉米品种‘衡星401’在7月25日播种其产量、株高和单株干物重表现最好，并且与其他处理之间差异显著，其中单株干物重与其他播期处理之间存在极显著差异(P<0.01)；而叶绿素含量却是7月15日播种时最高，除了与8月5日播种的处理无差异性显著以外，与其他2个处理之间差异性显著；另外不同播期对于叶片数的影响并不大。因此在江西及南方各地区‘衡星401’适合在7月15至25日之间播种。

Abstract:

This experiment is setted different sowing periods to observe the maize yield and plant characteristics in order to explore the ecological adaptability of ‘Hengxing 401’ on Paddy Field in Jiangxi. The results of this test showed that, when the seed of ‘Hengxing 401’ was sown in July 25th its yield, plant height and dry matter weight was the best performance, and significantly different with other treatments. In addition the dry matter weight had extremely significant difference with the others. The content of chlorophyll was the highest sown in July 15th, except had not significant difference with sown in August 5th, but had extremely significant difference with the other two. In addition the blade number of different sowing periods was little impact. Therefore, the breed of ‘Hengxing 401’ was properly cultivated during July 15th-25th in Jiangxi or the other southern regions.
