为防除水直播稻田阔叶杂草,我们进行了百草敌及百草敌与2甲4氯混用试验。一、48％百草敌单用水稻品种为双城糯。百草敌用量分每亩15毫升、20毫升、25毫升及空白对照4个处理,小区面积4米~2,重复2次,一次保水施药,一次排水施药,药后一天复水。用药时间为6月14日,即水稻6叶期,鳢肠2～4对叶。试验结果:保水施药区,药后2天,鳢肠叶片失水,4天逐渐恢复;排水施药区,鳢肠叶片严重失水,心叶迟出,叶缘下卷,生长停滞,10天后恢复正常。亩用15毫升处理对3对叶片以上的鳢肠无明显作用。各处理对水稻均安全。
In order to control the direct seeding of broad-leaved weeds in paddy fields, we conducted a mixed trial of paraquat and paraquat against 2-MCPD. First, 48% Herbivorous single rice varieties for the city waxy. Paraquat enemies amount of 15 acres per acre, 20 ml, 25 ml and blank control 4 treatment, the plot area of 4 m ~ 2, repeated 2 times, a water application, a drainage application, rehydration one day after treatment. Drug treatment time is June 14, that is, 6-leaf stage of rice, 2 ~ 4 pairs of leaves. Test results: water application area, 2 days after drug, water loss of the follicles, gradually recovered 4 days; drainage application area, intestinal follicles severe dehydration, delayed leaf edge, leaf margin, growth stagnation, 10 Days back to normal. Acre with 15 ml of treatment on the three follicles above the intestine no significant effect. All treatments are safe for rice.
