Field studies were conducted to evaluate the effects of agronomic practices such as rice straw mulches, planting density and ditch depth on control of rape weeds. The results showed that the overall weed control effects of rice straw coverage were above 85% and significantly increased the light intensity in rape fields. Denser rape transplantation could enhance crop competitive ability and increase the weed control effects accordingly. Ditches changed the water conditions in rape fields, and greatly reduced the infestation of Malachium aquaticum, Alopecurus aequalis, Beckmannia syzigachne and other worst weeds. Besides the weed control effects, the agronomic practices increased the yield of rape and had marked economic and ecological benefits.

研究了稻草覆盖、增加作物种植密度及开沟深度等农作措施对油菜田杂草的控制作用。结果表明,稻草覆盖总体控草效果可达85%以上,使油菜株间光照强度显著上升。增加油菜种植密度,可以增强植株整体竞争能力,对田间杂草的控制效果也逐步提高。油菜田开沟改变了田间的水湿条件,能显著降低田间恶性杂草牛繁缕、看麦娘及菵草的发生数量。农作措施在有效控制田间杂草危害的同时,使油菜产量显著提高。
