摘要
采用田间小区试验研究了几种防控方式下不同杂草的防效,结果表明,试验设计的5种(处理1～5)杂草有机防除方法单独使用,都不能有效控制移栽稻田全季杂草危害,并且持效期短。处理20d后,随着烤田等田间管理,杂草开始大量萌发,最终造成水稻减产。但是,水控+秸秆覆盖、水控+米糠、水控+白醋3个处理对稗草的发生有一定抑制作用。
The effect of different weeds under different control methods was studied by repeated experiments in the field plot.The results showed that five organic weed control methods designed in the experiment(treatment1~5)alone could not effectively control the weed damage in the whole season of the transplanted rice field,and the duration was short.After20d treatment,with field management such as roast field,weeds began to germinate in large quantities,resulting in rice yield reduction.However,water control+straw mulch,water control+rice bran,and water control+white vinegar had a certain inhibitory effect on the occurrence of barnyard grass.
