水稻“零天化除”机插秧技术应用效果及技术要点

Application Effects and Technical Points of the Zero-day Chemical Weeding Technology in Machine Transplanting Rice

为研究"零天化除"机插秧技术在水稻实际生产中的适用性,开展了"零天化除"高速插秧机和常规高速插秧机田间实际生产对比试验,并在田间测产和生产成本核算的基础上分析了该技术的经济效益。经核算,在其他生产条件相同的情况下,该技术可增产5.8%、增加收益84.69元/667 m^2。结果表明,"零天化除"机插秧技术在促进水稻生产机械化的同时,亦减少了用药次数,提高了生产效益,是一项高效省工节本的生产技术。

In order to study the applicability of the zero-day chemical weeding technology in machine-transplanted rice, a compara-tive experiment was carried out between the high-speed rice transplanter with zero-day chemical weeding technology and the conven-tional rice transplanter. On the basis of grain production estimate and production cost accounting, the economic benefits of the tech-nology were analyzed. After accounting, under the same production conditions, the zero-day chemical weeding technology increased the grain yield by 5.8% and the income by 84.69 yuan/667 m^2. The test results showed that the zero-day chemical weeding technology reduced the frequency of employing pesticide, improved the weeding efficiency meanwhile promoting the mechanization of rice produc-tion. It was an efficiency, labor-saving and cost-saving production technology.
