| 摘 要： | 为了研究玉米倒伏时产量影响的时期,从而提高气象服务的针对性,以嫩单12为试材,研究不同时期玉米倒伏对产量的影响。结果表明:玉米倒伏对玉米的产量有较为明显的影响,其中,倒伏与未倒伏的玉米相比,果实的穗粗、穗长、百粒重均有明显的影响,玉米果穗较短、较细,百粒重偏少。同时不同时期发生倒伏的玉米,对产量的影响也不相同,其中抽雄期倒伏对产量的影响最为明显。

| Abstract: | In order to study the influence period of lodging on the yield and improve the pertinence of the weath- er service, taking Nendan 12 as material, the effects of lodging on maize yield in different stages were investiga- ted. The results showed that the maize lodging had conspicuous effect on yield. Compared with the un-lodging maize,the lodging maize had obvious differences in the diameter and length of the spike and 100-grain weight, the lodging maize had a shorter and thinner spike and a lighter 100-grain weight. Moreover,the lodging in dif- ferent period had different effects on maize yield and had the greatest effect on yield in the tasseling stage. |
