赛克津具有杀草谱广、用药量低的特点,是防除豆田阔叶杂草较好的土壤处理剂,但因其水溶性较高也易造成药害。为摸索赛克津与外界条件的关系,我场在12个生产队使用,总施用面积716公顷,总结出以下几点规律。一、土壤有机质含量和土壤质地对赛克津的影响土壤有机质含量高,对药剂吸附能力强,因此在药量相同条件下,灭草效果相对 Saikaijin has broad spectrum to kill grass and low dosage, which is a better soil treatment agent for controlling broadleaf weeds in soybean field, but it is also easy to cause phytotoxicity because of its high water solubility. In order to explore the relationship between Saikjin and external conditions, I used the field in 12 production teams with a total area of ​​716 hectares and summed up the following rules. First, the impact of soil organic matter content and soil texture of metribuzin Soil organic matter content, adsorption capacity of the drug, so the same dosage, the weed effect relative
