为防治玉米田杂草危害,本研究采用玉米/豆科植物间作技术,通过在玉米行间撒播和条播豆类植物,从而达到抑制杂草生长的作用。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。
英文摘要:
In order to control the harm of weeds in maize field, the technology of intercropping leguminous plant in corn field was used in this study. The results showed that the growth of Digitaria sanguinalisS(L.) Scop., Eleusine indicaSS(L.) Gaertn., Amaranthus retroflexus L., Portulaca oleraceaSL.was obviously inhibited and the production of corn was increased because of the competition for space between the weeds and leguminous plant. In a word, the method of sowing green bean had the best effect on controlling the weeds and increasing the corn production.
