玉米新品种“衡星401”在红壤旱地种植的播期试验

The Experiment of Different Sowing Date for New Maize Variety of “Hengxing 401” in Red Upland

为了进一步明确播期在实际农业生产中对作物的影响,该文研究了4个不同播期对玉米新品种衡星401和江西省当地玉米品种科诺986株高、叶片长、叶片宽、单株干物重及产量的影响。结果表明:采取合理的播期不仅有利于改善玉米植株性状,而且有利于增加玉米叶绿素含量、单株干物重及产量,其中8月1日播种的衡星401和ck的产量分别比其它播期的增加了54.1%、3.9%、29.5%和51.2%、5.1%、28.4%。该研究得出,在实际农业生产中为保证产量,不仅要考虑播期,而且要考虑播期的天气状况。

In order to understand the eitects of sowing date on crops in actual agricultural production, the paper studied the effects of four different sowing dates on maize plant height, leaf length and width, dry matter weight per plant and yield of new maize variety Hengxing 401 and local maize variety Kenuo 986. The result indicated that reasonable sowing date can not only help to improve maize plant characters,but also help to enhance maize chlorophyll content, dry matter weight per plant and yield, when compared to other sowing dates, the yield of Hengxing 401 and local maize variety Kenuo 986 were increased by 54.1%, 3.9%, 29.5% and 51.2% ,5.1%, 28.4%. This study concluded that in order to achieve high yield, we not only need to consider sowing date in the actual agricuhural production ,but also need to consider weather conditions of sowing date.
