柳州地区是柑桔生产最适宜区之一。1986年种植面积已达10.7万亩,按“七五”规划。到1990年将发展到51.7万亩。随着种植而积的扩大,防除果园杂草危害成了柑桔生产中的突出问题。为了战胜草害,提高劳动效率,发展柑桔生产,我们于1986年使用化学除草剂克芜踪对柑桔园杂草进行了大田防治示范,效果显著。供示范用的克芜踪(Paraguat)20%水溶液为英国卜内门化学工业有限公司的产品。它又名百草枯、对草快。化学名称为1,1—二甲基—4,4—联吡啶阳离子盐。示范地选择在忻城县农科所四
Liuzhou is one of the most suitable areas for citrus production. 1986 planting area has reached 10.7 hectares, according to “seven five” plan. By 1990 it will develop to 51.7 million mu. With the expansion of cultivation and plot, the control of weed orchard hazards has become a prominent problem in citrus production. In order to defeat grass damage, improve labor efficiency, and develop citrus production, we conducted a field-based demonstration of prevention and control of weeds in citrus orchard with a chemical herbicide Ke Wuqi in 1986, with remarkable results. An exemplary 20% aqueous solution of Paraguat is a product of BP Chemical Industries Limited. It is also known as paraquat, fast to grass. The chemical name is 1,1-dimethyl-4,4-bipyridinium cation salt. Demonstrated to choose four in Xincheng County Agricultural Institute
