摘要
为了进一步了解国内外天然草地机械化改良技术,为今后的相关研究提供借鉴与参考,同时探索我国天然草地机械化改良技术的发展方向,对国内外近几年天然草地机械化改良技术进行了总结分析。分析认为,土壤与机具是改良退化天然草地的两大重要因素。国内外草地机械化改良技术主要包括机械化松土、施肥、补播等技术,改良机械有所不同;与国外草地机械化改良技术相比,我国草地机械化改良技术有一定限制,改良机具规格与作业范围有限,专用改良机具研究较少,退化草地土壤与作业机具作用关系的研究较少。我国天然草地机械化改良技术研究的方向是:以退化天然草地土壤为基础元素,进行退化草地土壤与改良机具作用关系研究;针对不同牧草品种与不同作业地形,研究有针对性的改良机具;进行天然草地打孔透气机械研究;探索性研究草地液态肥施肥机械。
To learn more about the mechanical restoration technology of the natural grassland, provide a reference for the following research and explore the development direction of our country natural grassland mechanization restoration technologies, the foreign and domestic progress in the mechanical restoration technology of the natural grassland in recent years was summed up and analyzed. It was thought that soil and equipment are two important keys in restoring degraded grasslands , mechanical restoration technology included mechanical ripper, fertilization and reseeding, but the machinery differ. , compared with the foreign mechanical restoration technology, the restoration mechanization of grassland in our country has certain limitation, research of Special improvement tools was less, so was function relationship research between the grassland soil and equipment. Study the function relationship research between the grassland soil and equipment based on the grassland soil , operation and restoration equipment adapt to different geography and forage species the liquid fertilizer fertilizing machinery and aerator, will be the future directions of the natural grassland mechanical restoration technology.
