Study on Impacts of Several Agents Defending and Removing the Weed in Rice Field and Effects of Their on Rice Yield

[目的]研究几种药剂防除稻田杂草的效果及对产量的影响。[方法]选用随机区组设计,观察水稻生育期,目测株高、分孽、叶片颜色及其他形态指数,调查除草效果,测定产量。[结果]结果表明,利用32%肥药颗粒剂防除稻田杂草,其防效均在90%以上,对水稻安全,无二次药害现象,对下茬无影响。[结论]施用32%肥药颗粒剂防除杂草可以达到省工、省时、增产的目的。

[ Objective] The research aimed to study the impacts of several agents defending and removing the weed in rice field and effects of their on rice yield. [ Method] The experiment took randomized block design,observed thegrowth period, plant height, leaf color of rice and so on, investigated the impacts of removing weed,and determined the rice yield. [Result] The results showed that the control effect of 32% Feiyao granules on the weed in rice field was over 90%, was safety to rice,and had no influence on the next crops. [ Conclusion] Appling the 32% Feiyao granules to defend and remove the weed in rice field can obtain the aim of saving labor,saving time and improving yield.
