我区国营农场现有耕地面积1350万亩,播种面积约1100万亩,每个农业职工担负耕地面积约20～30亩。种植的主要作物有小麦、玉米、水稻、棉花、甜菜等。由于农田杂草的种类多、数量大、适应性强,生长时期的不一致。虽然采用深耕地、播前整地、播后苗前耙地、苗期人工和机械中耕松土灭草等综合措施,但往往也难以彻底消灭杂草为害。同时增加耕作层次,耗费大批劳力,增大农业成本,很不适应农业生产的要求。近几年来,大面积推广化学除草,效果良好,深受广大群众欢迎。
The existing state-owned farms in our zone have an area of 1350 mu of arable land and sown area of about 11 million mu. Each agricultural worker owns arable land of about 20-30 mu. The main crops planted are wheat, corn, rice, cotton, sugar beet and so on. Due to the variety of farmland weeds, the number of large, adaptable, inconsistent growth period. Although the use of deep plowing, sowing before planting, sowing before sowing seedlings, seedling artificial and mechanized cultivation of soil weeding and other comprehensive measures, but often difficult to completely eliminate the weeds. At the same time increase the level of farming, consuming a lot of labor, increasing agricultural costs, it is not suited to the requirements of agricultural production. In recent years, large-scale promotion of chemical weeding, the effect is good, welcomed by the general public.
