在作物行间保持纯豆科覆盖是许多种植园的常规管理措施。影响保持纯覆盖的关键性问题之一是杂草的竞争。为了保证成功地建立起豆科覆盖,适当防除杂草是非常重要的。在应用化学药品防除覆盖作物中的杂草之前,多用手工除草,特别在杂草茂密的情况下,这项作业不仅麻烦而且花费大。因此,化学除草将取代手工除草或作为辅助的手段。 Maintaining pure legume coverage among crop lines is a routine management practice for many plantations. One of the key issues affecting the maintenance of pure coverage is weed competition. In order to ensure the successful establishment of leguminous cover, proper weeding control is very important. Before applying chemicals to control weeds in crops, weed-free weeds, especially in weeds, are troublesome and costly. As a result, chemical weeding will replace manual weeding or as an adjunct to it.
