摘要
论述了大豆大垅窄行密植与垄三栽培田杂草发生动态及作物对杂草的抑制能力,表明大垅窄行密植田杂草发生的数量偏多,生长后期具有明显的控草作用.控草时间在大豆播种后50～60d,即7月中下旬.大垅窄行密植对阔叶杂草抑制较明显.表明大垅窄行密植田杂草发生的数量偏多,生长后期具有明显的控草作用.控草时间在大豆播种后50～60d,即7月中下旬.大垅窄行密植对阔叶杂草抑制较明显.同时进行了大面积化学除草示范,形成杂草生态及化学调控的新体系.
This paper has discussed the developments of weeds and the restraining power of soybean plants on weeds between the serried row planting on broad platform and the three rows planting on per ridge. The demonstration experiment of chemical weeding in large area has been finished and the new system of weeds ecology and chemical regulation has been established.
