Studies on the Weed Developing Regularity and Controlling Technique for Agri-Grazing-Ecotone under Conservation Tillage in Maize Field
There were 30 species weed in wheat field from agri- grazing-ecotone for conservation tillage, their developing density and frequency were higher in conservation tillage than traditional tillage method about 31.8～42.6％ and 13.3～31.6％. Accordingly, their expanding condition was serious increasingly. Weed damage and its control in the maize field with conservation tillage planting method was investigated and experimented. Some measure were made mainly of Chemical herbicide、 mechanical method and the rotate farm. The result showed that the weed control could be treated in soil by莠去津、乙草胺、乙草胺+莠去津after seeding. It had good results for chemical herbicide in the seedling stage with玉农乐、玉农乐+2,4-D丁酯and after harvest make use of草甘膦In autumn. In addition, weed control of mechanical method had a good effect on fleet-furrow +scarification deeply+ cultivation. The compositive measure had a better outcome such as fleet-furrow + chemical herbicide, scarification deeply+ chemical herbicide, cultivation+ chemical ways.
