北哈萨克斯坦粗饲料生产主要来自割草场(达70—80%),且以种植鹅冠草为主,其高产可达10年。但经4—5年,由于土壤紧实,致使土壤水分、空气和营养状况变劣,导致草群退化,产草量降低。为了改善土壤水分的物理性质和营养状况,达到维持高产,延长使用期的目的,库斯坦奈农业试验站与“荒地农业机械化”科学生产联合公司共同进行了老龄多年生草地划破效果的研究。
North Kazakhstan roughage production mainly from the pasture (up to 70-80%), and the planting of crown grass-based, high-yield up to 10 years. However, after 4-5 years, soil moisture, air and nutrients deteriorate due to soil compaction, leading to the deterioration of grass groups and the reduction of grass production. In order to improve the physical properties and nutritional status of soil moisture and achieve the purpose of maintaining high yield and prolonging the service life, CST conducted a research on the effect of perennial grass scribing by cooperating with “Wild Land Agricultural Mechanization” Scientific Production Joint Venture.
