摘要:
于2020年进行不同封闭除草剂与施用方式防除机插稻田杂草效果及安全性的田间试验。结果表明,苄嘧·丙草胺复配剂、丙草胺与丙嗪嘧磺隆混配机插同步喷施对水稻安全,但丙草胺与双唑草腈混配机插同步喷施能降低水稻分蘖。随灌溉水施用双唑草腈对水稻安全,但杂草防效受田块平整性限制,均一性差。插秧后15 d,各处理杂草株防效均大于95%。插秧后30 d,30%苄嘧·丙草胺同步喷施,阔叶杂草株防效虽下降,但禾本科杂草及阔叶杂草鲜质量防效均高于94%;9.5%丙嗪嘧磺隆+30%丙草胺同步喷施,禾本科杂草、阔叶杂草株防效均显著下降,且对千金子和水苋菜株防效为100%。与常规2次封闭除草比较,机插同步喷施除草剂方式杂草防效较高,虽施药成本相当,但除草剂用量低,且操作简便、施药均匀。
