甜菜应用地膜覆盖栽培技术,由于改善了土壤的水、肥、气、热状况,有利于甜菜的生长发育,增产显著。然而,地膜甜菜在生产中往往由于破洞放苗后封土不及时或压膜不严等原因常造成杂草疯长或形成草荒,不仅增加了人工除草的劳动强度,费时、费工、费力,也影响到地膜效应的充分发挥。为此,石河子甜菜研究所在科委的大力支持下,经过两年的试验示范,筛选出了适合地膜甜菜播前土壤处理的除草剂——杜尔，该研究已通过石河子可科委成果鉴定可以大面积推广应用。
Sugar beet mulching cultivation techniques, due to improved soil water, fertilizer, gas and heat conditions, is conducive to the growth and development of sugar beet, yield significant. However, in the production of mulberry beet, the weed often grows up or forms a wasteland due to the improper sealing of the mulched beetle after planting or the lamination of the mulch film, which not only increases the labor intensity of artificial weeding, but also takes time, effort and effort. Affect the full play of the film effect. To this end, Shihezi beet Institute with the strong support of the Science and Technology Commission, after two years of pilot demonstration, screening for the film mulched sugar beet herbicide - Dour, the study has been identified through the results of Shihezi Science and Technology Commission Can promote the application of a large area.
