摘  要：
试验研究了55%吡嘧磺隆·二甲四氯钠·氯氟吡氧乙酸异辛酯WP防除水稻移栽田主要阔叶杂草和莎草科杂草的效果,以及对田间水肥的影响。结果表明,施用55%吡嘧磺隆·二甲四氯钠·氯氟吡氧乙酸异辛酯WP对移栽稻田空心莲子草(Alternanthera philoxeroides)、异型莎草(Cyperus difformis)、鸭舌草(Monochoria vaginalis)的综合防效可达92.88%~99.71%,有效改善了田间的水肥条件,比CK未施药增产27.62%~33.31%,增产效果显著。

摘  要：
Effects of pyrazosulfuron-ethyl·mcpa-na·fluroxypyr-1-methylheptylester WP with 55% content on broadleaf and cyperaceae weeds, water and nutrition of soil were studied in rice field. The results showed that the control efficiency of Alternanthera philoxeroides, Cyperus difformis and Monochoria vaginalis could reach up to 92.88%~99.71%. Application of pyrazosulfuron-ethyl·mcpa-na·fluroxypyr-1-methylheptylester WP with 55% content significantly improved the light condition in the rice field and reduced the absorption of nutrition and water by broadleaf and cyperaceae weeds. And then, it resulted in a significant increase of rice yield with 27.62%~33.31% higher than CK.
