我省农田化学除草中,麦田化除一直占有很大比例。近几年,麦田实行免耕,既省工又高产,正迅速被广大农户采用。1985年冬,我们分别在临安县西墅村陈朝荣户和余杭县长乐村陈文贤户的稻茬麦田,利用草甘膦和百草枯具有灭生性和遇土易纯化的原理,进行了对播前早期草害的防除试验,并取得了良好效果。临安等地今冬已打算较大面积应用推广。现将试验情况整理如下。材料与方法陈朝荣户和陈文贤户麦田的试验处理及材料分别如表1、表2所述。陈朝荣户麦田前作
In our province farmland chemical weeding, in addition to wheat field has always accounted for a large proportion. In recent years, no tillage has been implemented in the fields of wheat, which not only saves labor but also produces high-yield crops, which are rapidly being adopted by farmers. In the winter of 1985, we used the principle that glyphosate and paraquat were both biocidally degradable and easy to be purified in the fields of Chenzhao Rong, Xishu Village, Lin’an County, and Chen Wenxian, Changle Village, Yuhang County, respectively. Grass control and prevention and control, and achieved good results. Lin’an and other places in winter has intended to promote the application of a larger area. The test situation is now organized as follows. Materials and methods Chen Chaorong households and Chen Wenxian wheat field trial treatment and materials as shown in Table 1, Table 2 described.
