摘要
振动深松技术是在原有的深松技术的基础上和引进日本的先进设备,通过消化、吸收、创新,成功地创造和形成适合我国国情的振动深松技术。在解决土壤板结、建立“土壤水库”、草原改良、低产田改造、根茎收获等方面得到了广泛的应用,取得了巨大的经济效益。通过土壤水动力学的方法就其“土壤水库”能够调节土壤水分的机理进行了试验研究和探讨,初步揭示了振动深松蓄水保墒的机理,为该技术提供了理论依据。
Deeply vibrating-loosen technology is an introduced advanced equipment from Japan. Upon already existed foundation of loosen technology in our country, through digesting, absorbing, innovating, it succeeds in creating and forming the new type deeply vibrating-loosen technology which suit our country＇s national conditions, and is widely used in solving the soil hardening, setting up “soil reservoir”, improving grassland, transforming low-yield land, reaping rhizome etc. This paper studies and discusses their mechanism through a mass of experiments with methods in water dynamics on “soil reservoir”, and announces tentatively mechanism in deeply vibrating-loosen and storage and preservation of soil moisture, and offers the theoretical foundation for this technology.
