浅谈2013年度濮阳冬小麦的田间管理

通过遥感监测的2013年9月～2014年3月冬小麦出苗率和土壤墒情的分析,对冬小麦的田间管理作出合理性建议.结果表明,2013年9月～2014年3月濮阳市降水量偏少,且分布不均,天气较为干燥,对冬小麦的生长影响较大.特别是进入4月份以后小麦生理上进入孕穗期,先后开花、授粉、灌浆;小麦的需水量增大,另外随着气温的升高,病虫害会大量发生,因此加强对冬小麦的田间管理工作、做好冬小麦田地土壤墒情监测、抓住有利天气条件实施人工降雨作业至关重要,这对缓解旱情、降低自然灾害对作物的影响意义重大.

Winter Wheat Field Management in Puyang in 2013
