摘要：

本文应用“二封一补”的策略完成黑龙江省水直播田杂草的药剂系统防控试验,结果表明,在16个有效处理中,处理5（25%噁草酮EC+25%丙炔噁草酮OD+10%吡嘧磺隆WP,50%丙草胺EC+33%嗪吡嘧磺隆WG,5%五氟磺草胺OD+30%氰氟草酯OD）防控效果最好,对总杂草的株数相对防效和鲜质量相对防效均为100%,产量也最高,达到7.77 t/hm2;处理6（25%噁草酮EC+25%丙炔噁草酮OD+10%吡嘧磺隆WP,50%丙草胺EC+33%嗪吡嘧磺隆WG,5%五氟磺草胺OD+48%灭草松AS）防控效果次之,对总杂草的株相对防效和鲜质量相对防效分别为99.92%和99.74%,产量也较高,达到7.65 t/hm2。此外,从首次出苗率、分蘖动态、株高动态、千粒重和结实率等指标来看,各处理间差别很小,无药害问题。

Abstract:

The test of herbicide system control to weeds of water direct seeding rice was carried out in Heilongjiang province. The main results indicated as follow: among the 16 treatments, the treatment 5 （25% oxadiazon EC+25% oxadiargyl OD+10% pyrazosulfuron WP, 50% pretilachlor EC+33% metazosulfuron WG, 5% penoxsulam OD+30% cyhalofop-butyl OD） had the best control effects with 100% relative control effects on weed number and weed fresh weight, and the highest yield reaching 7.77 t/hm2. The control effects of treatment 6 （25% oxadiazon EC+25% oxadiargyl OD+10% pyrazosulfuron WP, 50% pretilachlor EC+33% metazosulfuron WG, 5% penoxsulam OD+48% bentazon AS） was the second, the relative control effects of weed number and weed fresh weight were 99.92% and 99.74%, respectively, and the rice yield was the second, reaching 7.65 t/hm2. In addition, judging from the results of first emergence rate, tiller dynamics, plant height, 1000-grain weight and seed setting rate, the differences between all treatments are small and there were no herbicide damage problem.
