摘要: 为了筛选燕麦田高效安全的除草剂,在山西北部地区开展了田间试验,选取田普除草剂(主要成分为二甲戊灵)为试验药剂,8种不同生态型的燕麦品种为供试品种,检验该除草剂对不同品种产量和安全性的影响。研究结果表明:田普除草剂对藜科、蓼科、禾本科、苋科杂草效果较明显,尤其是对藜科杂草的防治效果最好,最高的达到了100%,而对马齿苋科、菊科、旋花科杂草效果不好;使用田普除草剂处理对燕麦品种的穗长、轮层数、小穗数等性状有一定的抑制作用,对籽实千粒重的有促进作用;本研究中喷施除草剂的处理的平均籽实产量比不喷施除草剂的处理和人工除草处理分别增产70.5%和4.3%。此外,该除草剂未对后茬作物(油菜)产生明显药害作用,可对燕麦-油菜倒茬安全使用。

Abstract: In order to choose high efficient and safe herbicide, field experiments were carried out in north Shanxi.‘Tianpu’herbicide (dominant ingredient was pendimethalin) was used as the test agent and 8 different types of oat varieties were used. The results showed that control effect of ‘Tianpu’ herbicide on Chenopodiaceae, Polygonaceae, Gramineae and Amaranthaceae weed was obvious, especially on Chenopodiaceae weed, the control effect reached the highest of 100%, and the control effect on Portulacaceae, Compositae and Convolvulaceae weed was not good;‘Tianpu’herbicide had certain inhibiting effect on ear length, round number and spikelet number, and had promoting effect on 1000 seed weight; the average grain yield of herbicide treatment increased by 70.5% and 4.3% respectively compared with that of no-herbicide treatment and artificial weeding treatment. This herbicide did not have obvious phytotoxicity effect on the after reap crop (rape), which could be used safely in oat-rape rotation.
