一、前言氟乐灵(Trifluralin)化学成分为2.6-二硝基-N,N-二丙基-4-三氟对甲苯胺,是一种适用于大豆、棉花、花生等多种作物的优良除草剂,用于作物播种前或播种后出苗前,进行土壤处理。据报导,该除草剂施于土壤表面后极易挥发和光解,在施药后最初一段时间消失较快,以后逐渐减慢。氟乐灵在不同气候和土壤条件下,土壤中的残效期差别很大,从3个月到18个月不等。为了明确氟乐灵在我省条件下,对主要杂草种类的
I. Preface Trifluralin has a chemical composition of 2.6-dinitro-N, N-dipropyl-4-trifluoro-p-toluidine, which is an excellent compound for many crops such as soybean, cotton and peanut Herbicides for soil treatment before sowing or sowing after emergence. It is reported that the herbicide applied to the soil surface is very volatile and photolysis, the first period of time disappeared quickly after application, then gradually slow down. Trifluralin varies greatly in soil residuals from 3 months to 18 months under different climates and soil conditions. In order to clarify trifluralin in the province under the conditions of the main types of weeds
