扩大三熟制种植面积是提高全年粮食产量的重要途径。但是,由于春粮面积的扩大,特别是推广撒播麦后,麦田草荒成为春粮高产的严重障碍。为了解决这个问题,前几年我们曾采用过以土压草、以苗压草和扑草净除草等措施,但都没有解决草荒问题。我们从稻田化学除草获得较好效果的启发,试用绿麦隆防治麦田杂草,现初报如下: The expansion of the area planted with three crops is an important way to increase the annual grain output. However, due to the expansion of the area of ​​spring grain, especially after the spread of sowing wheat, the grassland wasteland has become a serious obstacle to the high yield of spring grain. In order to solve this problem, a few years ago we used soil pressure grass, moth pressure grass and prometryne net weeding measures, but they did not solve the problem of grass wasteland. We inspired from the chemical weed in paddy field to obtain better results, try green wheat weed control weeds, are reported as follows:
