摘要
针对大豆田缺苗断条现象,进行调查研究分析,总结造成此现象的原因是在选种、整地、施肥、用药、播种五个关键环节存在问题:种子质量差,整地达不到标准;种肥同层施或施劣质肥;种衣剂成分、用量种类及使用方法不当;封闭除草用药不当;播种质量及时期不当等。
This article aims at investigating the phenomenon of missing seedlings in the soybean farmland. The reason of this phenomenon lies in five key aspects： seed selection, soil preparation, fertilization, pesticides application and sowing. Bad seed quality and not carefully selected before sowing, poor soil preparation, simultaneous sowing with fertili- zers, inferior quality fertilizers, inappropriate use of seed coating and herbicide all contribute to the uneven emergence of seedlings.
