丽水地区撒播麦田杂草为害比较普遍。主要杂草有看麦娘、碎米荠、雀舌草、繁缕等,在草害严重的田块,每平方尺有看麦娘等杂草1000多株,严重影响麦苗生长,妨碍麦子高产。贫下中农说:“撒播好是好,就是难除草,杂草除不了,产量也不高。”他们迫切要求解决撒播麦田的除草问题。1971年起我组与贫下中农和场所职工一起进行撒播麦田化学除草试验,1972～1973年全区试验应用面积约800亩。现将应用的几种药剂介绍如下:
Weeds spread in wheat fields in Lishui are more common. The main weeds have to see Amanita, chestnut chestnut, quebracho, chickweed and so on, in the grass-serious plots, each square foot to see Anemarrhena and other weeds more than 1000 strains of wheat seedlings seriously affect the growth, hinder the wheat yield . Poor middle peasants said: “Spreading good is good, it is difficult to weed, weeds can not be removed, the yield is not high.” They are urgently required to solve the weeding in sowing wheat fields. Since 1971, our group has carried out chemical wheat weeding tests together with poor middle peasants and workers in the fields. From 1972 to 1973, the test area of the whole region was about 800 mu. Now the application of several agents described below:
