Abstract: | The efficacy of rice bran and film mulching cultivation to control main weeds in rice was evaluated.Film mulching cultivation was more effective than rice bran at 2 000 kg/hm2 in controlling Echinochloa crusgalli (L.) Beauv.,Cyperus rotundus L.,Monochoria vaginalis (Burm.f.) Presl.,and Heleocharis plantagineiformis Tang et Wang with 129%,64%,90%,57.1% higher plant individual efficacy,and 123%,38%,98%,42% fresh weight control effect repectively.It increased the economic benefit up to 9784 yuan/hm2. |
