哌草津又叫排草净是哌草磷和戍草嗪的混合物,用于防除稻田杂草的一种选择性内吸传导型除草剂,杀草原理是从杂草根部和茎叶部吸收后,抑制核酸和蛋白质的合成,并抑制光合作用。哌草津在土壤中移动性小,受气象条件及土质条件影响也小。我们从1981年开始小区试验,1982年进行多点大区对比试验。 Piperazine is also known as Paeoniflorin, a compound of penteretin and garbuteride. It is a selective systemic sorbent that is used to control weeds in paddy fields. The principle of herbicide is that it is absorbed from roots and stems of weeds , Inhibit nucleic acid and protein synthesis, and inhibit photosynthesis. Piperzine in the soil mobility is small, by the weather conditions and soil conditions are also small.
