摘要
为明确拜田净对水田杂草的防治效果,在田间采用大区对比法进行药效试验。结果表明,拜田净50%可湿性粉剂300g/hm2+草克星10%可湿性粉剂225g/hm2,在水稻移栽田一次性施用,对禾本科杂草防效100%,对阔叶杂草防效93%,对水稻不但安全,而且使水稻分蘖多、无效分蘖少、生长快,增产显著。比禾大壮+草克星或丁草胺+草克星效果好。
In order to clean out the effect of weed control by using Baitia ni jing,made an experiment adopting the means of comparing between the great area s.The result shows 50%Baitianjing SP(soluble power)combining with10%NC-311225g/hm 2 onetime sprayed on transplanted rice control Gramineae weeds by100%,an d control broadleaf weeds by93%adding to safety and more tillerings,less una vailable tillerings,growing faster and increasing yield.Comparing with Ordram adds NC-311or butachlor add NC-311,the former is better.
