为提高氮肥利用率,吉林省化肥试验网在研究西呲(三氯甲基吡啶)效果的同时,研究了除草剂五氯酚钠与氮肥在水田混用的效果。试验结果表明,五氯酚钠具有抑制土壤硝化作用、稳定氨态氮的能力,两者混用,既能除草又能提高肥效。一、混用的方法与效果试验在七种类型土壤的稻田进行。供试氮肥为尿素与碳酸氢铵;五氯酚钠(65%)为沈阳化工厂产品。混合方式分机械混合(7%五氯酚尿素与15%五氯酚尿素,由沈阳化工研究院加工制造)与人工混合。
In order to improve the utilization of nitrogen fertilizer, Jilin Province Fertilizer Experimental Network in the study of the West Briz (trichloromethyl pyridine) effect at the same time, we studied the effect of the herbicide sodium pentachlorophenate and nitrogen in paddy fields. The test results showed that sodium pentachlorophenol has the ability of inhibiting soil nitrification and stabilizing ammonia nitrogen, and the two can be mixed to both weed control and fertilizer efficiency. First, the method and effect of mixed experiments in seven types of paddy soil. Nitrogen for the test urea and ammonium bicarbonate; pentachlorophenol sodium (65%) for the Shenyang Chemical Plant products. Mixed means of mechanical mixing (7% pentachlorophenol urea and 15% pentachlorophenol, manufactured by the Shenyang Chemical Research Institute) and artificial mixing.
