| Abstract: | The results of rape field experiment showed that the synthetic control effects of applying 50% Metazachlor·Clomazone EC 525~1125 g(ai)/hm2 against the density of Aolpecurus aequalis,Beckmannia erucaeformis and Malachium aquaticum were 92.32%~100%,91.07%~99.68% and 92.07%~99.83% respectively on the 30th,60th and 90th day after spraying,and its synthetic control effect against the fresh weight of above three weeds reached to over 93% on the 90th day after spraying.The application of 50% Metazachlor·Clomazone EC could significantly improve the light condition in rapeseed field,reduce the absorption of weeds to nutrition and water,and enhance rapeseed yield by 29.01%~29.48%. |
