温州地区危害麦类的主要杂草有1O余种之多,其中以看麦娘和繁缕两杂草最为猖獗。经调查一般田块每平方尺的杂草在100株左右,严重田块可达400株以上,局部点、片甚至出现“草荒”,严重地影响麦苗的生长。随着科学种田水平的提高,根除麦田杂草,已成为广大贫下中农的迫切要求和希望,特别是撒播麦田的面积不断扩大,麦田除草更为当前急待解决的问题。为此,我们在1972年对50％除草剂一号可湿性粉剂(天津农药实验厂)50％扑草净可湿性粉剂(上海红卫农药厂产品)和25％绿麦隆可湿性粉剂(上海农药厂产品)等药剂,开展田间小区试验和较大面积示范,现将试验结果整理如下:
The main weeds that threaten wheat germplasm in Wenzhou are more than 10 species, of which the weeds are the most rampant. After the investigation of general field plots of weeds in about 100 per square foot, severe plots up to 400 or more, local spots, tablets or even “grass shortage” seriously affect the growth of wheat seedlings. With the improvement of scientific farming, the eradication of weeds in wheat fields has become an urgent demand and hope for the majority of poor and middle-income peasants. In particular, the area of sowing wheat fields is constantly expanding and weeding on the wheat fields is a more urgent issue to be solved urgently. To this end, we in 1972 on 50% Herbicide No. 1 wettable powder (Tianjin Pesticide Experimental Factory) 50% prometryne WP (Shanghai Hongwei Pesticide Products) and 25% Chlorotoluron wettable powder (Shanghai Pesticide products) and other pharmaceutical agents to carry out field trials and large area demonstration, the test results are summarized as follows:
