在近年试验的基础上,通过重大病虫监测,运用高效、低毒农药和“一喷多防”、“一药多用”技术措施,在单季稻大田开展了重大病虫害农药减量控害技术的全程示范,实现了对单季稻重大病虫害有效控制。示范结果表明,高效、低毒农药减量控害技术示范田比当地农户常规用药区平均减少病虫害防治3次,防治效果高3.0~17.7个百分点,农药使用量(折100%纯量)下降65.97%,减少了农药对环境的污染,增加稻谷单产1 144.5 kg/hm~2,按本地晚粳谷3.26元/kg计,增加产值3 731元/hm~2,加上节省防治成本60元/hm~2,试验示范区合计增加效益3 791元/hm~2。
On the basis of the recent experiments, the major pests and diseases pest monitoring, the use of high efficiency, low toxicity pesticides and “a spray more prevention ”, “a drug multipurpose ” technical measures, Demonstration of the full impact of technology, to achieve a single crop of pests and diseases of rice effective control. Demonstration results showed that the demonstration plots of high efficiency and low toxicity pesticide reduction and control technology reduced pest and disease control by 3 times on average compared with the routine drug use area of local farmers and the control effect was 3.0 to 17.7 percentage points higher and the pesticide usage (off 100% pure) decreased by 65.97 %, Reducing the pollution of pesticides to the environment, increasing paddy yield of 1 144.5 kg / hm ~ 2, according to the local late japonica valley 3.26 yuan / kg dollars, increasing the output value of 3 731 yuan / hm 2, plus saving the prevention and treatment costs 60 yuan / hm ~ 2, Experimental demonstration zone total increase benefit 3 791 yuan / hm ~ 2.
