我省稻后种植蚕豆,由于田间湿度大,气温较高,按豆后杂草发生快,密度大。蚕豆田一般以看麦娘、棒头草、繁缕、苦草等杂草为主。为探索蚕豆田化学除草的应用技术,今年我们在玉溪县城关公社中卫四队,对各种除草剂在蚕豆播后苗前施用,观察对蚕豆的安全性和除草效果的初步试验,现将结果简报如下。试验田土质胶泥,中等肥力,前作水稻9月中旬收割。下旬开沟作墒,将沟泥提在 After planting rice in Hunan province, due to high humidity in the field, the temperature is higher, the bean weeds occur faster and the density is higher. Fava bean field generally see Maiang, head grass, chickweed, bitter grass and other weeds-based. In order to explore the application of broad bean weeding technology, this year we are in Yuxi County Chengguan commune Zhongwei four teams of all kinds of herbicides in broad bean sowing after the application of seedlings to observe the safety of beans and herbicides preliminary test results now results Briefing is as follows. Experimental soil clay, medium fertility, pre-harvest rice in mid-September harvest. In late trenches for soil moisture, ditch mud mention in
