我市是甜菜栽培老产区,随着科学种田水平的提高,单位面积产量不断增加,经济效益愈加明显。历年栽培面积约9.5万亩,占经济作物面积的15.4％,效益占总经济作物的21.1％,是当地主要经济作物。农田杂草的危害是夺取甜菜丰收的主要障碍之一,为解放农村劳动力、降低劳动强度,大幅度提高经济效益,曾用拿扑净等药剂除草,但只能防除禾本科杂草,致使阔叶草数量大增,危害较重,因此采用凯米丰和甜安宁单用防除阔叶草,并分别与拿扑净合用防除各种杂草进行试验研究,取得明显效果,总结如下。
The city is an old growing area of beet cultivation. With the improvement of scientific farming, the output per unit area is constantly increasing, and the economic benefits are even more obvious. Over the years cultivated area of about 95,000 mu, accounting for 15.4% of the area of cash crops, the benefit of the total economic crop 21.1%, is the main cash crop. Harms of weeds in farmland are one of the main obstacles to the success of sugar beet harvest. In order to liberate rural labor force, reduce labor intensity and greatly improve economic efficiency, weeding herbicide such as weed net, but weeding only can prevent grass weeds, Therefore, the use of KemFeng and sweet peace alone with broadleaf control, respectively, and take the net flutter with a variety of weed control study and achieved significant results are summarized below.
