一、试验目的红花是察布查尔县重要经济作物之一,近几年,由于种植结构调整、栽培技术更新,红花种植面积稳步上升,目前已达到1万公顷左右。但是,由于连作、大面积秸秆还田和未腐熟有机肥的使用,以及农民对红花田杂草使用除草剂品种不当和防除时间的不适等原因,造成红花田杂草危害连年加重,严重影响红花产量和质量。为有效控制草害,筛选出经济效益高、使用方便、低毒、低残留的有效药剂,特进行以下几种化学除草剂田间药效对比试验。二、供试材料
First, the purpose of the test Saffron is one of Chabuchar County, one of the important economic crops, in recent years, due to the adjustment of planting structure, cultivation techniques, safflower planting area increased steadily, has now reached 10,000 hectares. However, due to continuous cropping, the use of large-area straw returning and non-decomposing organic fertilizer, improper varieties of herbicide for weed in red field and the discomfort of control time, the weeds in red flower field have been aggravated year by year. Affect safflower production and quality. In order to effectively control the grass-roots damage, select the effective pharmaceuticals with high economic benefits, easy to use, low toxicity and low residue, and conduct the following comparative tests on the field efficacy of the following chemical herbicides. Second, the test materials
