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

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 the growth 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.
