采用玉米/豆科植物间作技术,通过在玉米行间撒播和条播豆类植物,研究玉米/豆科植物间作对抑制杂草生长的作用,防治玉米田杂草危害。结果表明,豆科植物通过与杂草的空间竞争,对玉米田中经常发生的杂草马唐、牛筋草、反枝苋、马齿苋等具有明显的控制效果,并对玉米有一定的增产作用。综合比较,绿豆撒播的种植方式对杂草的防控效果和对玉米的增产作用最好。
Maize / legume intercropping techniques were used to study the effect of intercropping corn / leguminous plants on weed suppression and the weed control in corn fields by sowing and sowing legumes between corn rows. The results showed that the leguminous plants had obvious control effects on the weeds Crabgrass, the tendon grass, the Amaranthus retroflexus, purslane and so on in the maize field through the space competition with the weeds, and had certain yield increase to the maize effect. Comprehensive comparison, mung bean planting methods of weed control and weed control effect of corn yield the best.
