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 weather service,taking Nendan 12 as material,the effects of lodging on maize yield in different stages were investigated.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 different period had different effects on maize yield and had the greatest effect on yield in the tasseling stage.
