棉花,蚕豆皆为本市重要的经济作物。受地理环境及耕作制度的影响,这两类作物田的草相也多种多样,而且种类多,密度大。由于缺乏理想的选择性除草剂,棉田特别是蚕豆田杂草的防除一直是个困扰当地群众的难题,因而多采用人工除草的方法,不仅花工量大而且也难以除尽。为此,我们试验探讨了用灭生性除草剂克芜踪在作物行间进行定向喷雾防除杂草的方法,取得了明显的效果。现介绍如下。 Cotton, fava beans are important economic crops in the city. Affected by the geographical environment and farming system, the grass fields of these two types of crop fields are also diverse and varied in variety and density. Due to the lack of ideal selective herbicides, the prevention and control of weeds in cotton fields, especially the broad bean fields, has always been a problem that plagues the local people. Therefore, the method of artificial weeding is often used, which is not only labor-intensive but also difficult to eliminate. To this end, we have explored the use of biocidal herbicides Wu Wu trace directional crop spraying between rows of weeds control method, and achieved significant results. Now introduced as follows.
