摘要
对截至2022年6月25日中国农药信息网登记的春玉米田除草剂相关登记数据进行了统计、整理、分析,包括除草剂的登记数量、登记企业分布、剂型、品种、作用方式。东北地区广泛种植玉米,然而东北地区包括黑龙江省、东北中西部地区、辽宁省因干旱和农户知识匮乏等原因,除草剂超量使用;因施药设备不正规、施药设备落后等问题除草剂药效减弱、土壤受到影响。根据不同地区存在的问题,提出了除草剂使用相关意见、建议。
The collation,statistics and analysis to the registration data of herbicides in spring corn fields on the China Pesticide Information Network before June 25,2022,including the registered number of herbicides,the distribution of registered enterprises,formulations,varieties,and modes of action are conducted.The corn is widely planted in the northeastern region.The current situation and existing problems of herbicide use in the northeastern region,including Heilongjiang Province,the central and western regions of Northeast China,and Liaoning Province,are summarized and analyzed.Due to the drought and farmer lacking of knowledge of herbicide use,excessive herbicides are used,and irregular spraying equipment,backward spraying equipment and other problems have weakened the efficacy of the herbicides and destroyed the land.Different regions have different problems.According to the existing problems of different areas of northeast China,opinions and suggestions on herbicide use are put forward.
