阿荣旗大豆播种面积占总播种面积的15%,大豆田的草荒直接影响了大豆的稳产高产。根据有关资料介绍,我们进行了大豆田喷氟乐灵的试验,杀草效果显著。实验是在旗实验站的田里进行的苗带喷雾。按1:100的比例将氟乐灵用水稀释,土质为黑土,墒情好,大豆长出一对单叶时进行,每亩用药0.3斤。六天后观察,发现施药的有萎蔫和干枯死亡的草芽,有少量杂草的胚芽鞘肿大,幼苗颜色深绿,比对照约矮一厘米。13天后观察,幼苗的颜色、高矮与对照无明显差别,每米苗带(宽20厘米)中的杂草株
Arong Soybean sown area of ?? 15% of the total sown area, the grassland of soybean fields directly affect the soybean yield and stable yield. According to the information, we conducted a trial of trifloxacin in soybean field, killing grass significantly. The experiment is a seedling spray in the field of the flag laboratory. According to the ratio of 1: 100 trifluralin diluted with water, soil is black soil, good soil moisture, when the leaves grow a pair of leaves, 0.3 kg per mu medication. After six days of observation, found that the application of wilted and withered dead buds, a small amount of weed coral sheath swelling, dark green seedlings, about one centimeter shorter than the control. After 13 days of observation, the color and height of the seedlings were not significantly different from those of the control. The weed strains (20 cm wide) per meter
