利用除草地膜(黑膜、绿膜),覆盖圆葱防治杂草。圆葱是辽宁省葫芦岛市主要蔬菜作物之一,除供应本地市民食用外,还大量出口俄、日和韩等国。在过去圆葱生产中,由于使用普通透明膜覆盖,不仅极易造成圆葱的徒长、倒伏、早衰等,而且还会使膜下杂草丛生,形成草棚,降低圆葱产量。为清除杂草而使用除草剂,不但会造成圆葱污染、土壤污染、地下水污染,而且还会降低圆葱质量,减少农民的收入。为了解决清除杂草、提高圆葱质量和保护环境之间的矛盾,2006年采用了除草黑膜和绿膜覆盖圆葱防治杂草的技术,取得了很好的效果。经黑膜、绿膜与普通透明膜进行对比试验,不仅避免了应用除草剂除草污染圆葱和环境的问题,而且还有效地解决了因覆盖普通透明膜造成圆葱地中杂草丛生的难题,获得了经济效益和生态效益双丰收。 Use of weeding film (black film, green film), covered with onions to control weeds. Onion is one of the main vegetable crops in Huludao City, Liaoning Province. Apart from supplying food to local residents, it is also exported to Russia, Japan, South Korea and other countries in large quantities. In the past onion production, due to the use of ordinary transparent film covered, not only can easily cause Onion leggy, lodging, premature aging, etc., but also make the film covered with weeds, the formation of sheds, reduce onion production. The use of herbicides to remove weeds not only causes onions, soil pollution and groundwater pollution, but also reduces the quality of onions and reduces the income of farmers. In order to solve the problem of clearing weeds, improving the quality of green onion and protecting the environment, we used the technology of weeding with black film and green film to cover weeds in weeds in 2006 and achieved good results. The contrast test of the black film, the green film and the ordinary transparent film not only avoids the problem of applying the herbicide to weed polluting the onion and the environment, but also effectively solves the problem of overgrown weeds in the onion due to covering the common transparent film , Access to a double harvest of economic and ecological benefits.
