2011年冬前气温偏高,进入越冬期比常年晚,早播麦田群体偏大。据北京市气象局、气候中心预测,今春降水量将比常年偏多,平均气温略偏高,有利于小麦群体增加和病虫草害的发生,所以要高度重视病虫草害的防治,及早采取以下措施。 The temperature in winter before 2011 is high, entering winter is later than usual, and the population of early-sown wheat fields is larger. According to Beijing Meteorological Administration and Climate Center, precipitation will be more than normal this year and the average temperature is slightly higher, which is conducive to the increase of wheat populations and the occurrence of pests, diseases and weeds. Therefore, we should attach great importance to the prevention and control of pests and weeds as soon as possible Measures.
