- 摘要:
- 以倒伏后的郑单958为材料,对不同地块籽粒的灌浆特性和病虫害发生情况进行了比较分析。结果表明:倒伏下部的灌浆速率低于倒伏上部植株,倒伏上部植株的灌浆速率低于短期积水地块的植株,短期积水地块的灌浆速率低于正常植株;倒伏下部植株的霉变率、虫蛀率和蟋蟀危害率均明显高于倒伏上部的植株。
- Abstract:
- Taking the lodging maize Zhengdan 958 as the materials,the grain filling feature and the diseases and insects pests of the different places were compared and analyzed.The results indicated:the grain filling speed of lodging bottom below that of lodging top,the grain filling speed of lodging top below that of the maize with flood shortdated,the grain filling speed of the maize with flood shortdated below that of the normal maize.The moldy percentages,infested rate,the destroyed rate by crickets of lodging bottom were significantly exceeded the maize of lodging top.
