土壤耕作是农业生产上的重要增产技术措施,它起着调节土壤水、肥、气、热状况、促进土壤养分转化的重要作用。随着农业生产的发展,土壤耕作技术也在逐步得以改进和创新,山西省水土保持科学研究所高级工程师史观义等创造的旱农蓄水聚肥改土耕作法就是其中之一。 Soil cultivation is an important technical measure to increase production in agricultural production. It plays an important role in regulating soil water, fertilizer, gas and heat conditions and promoting the conversion of soil nutrients. With the development of agricultural production, soil tillage technology is also gradually being improved and innovated. One of them is the dry farming, water diversification and fertilizer reform, which was created by Shi Guanyi, a senior engineer of Shanxi Provincial Institute of Soil and Water Conservation.
