蓄水聚肥改土耕作法(也叫抗旱丰产沟耕作法),是山西省水土保持科研所发明的一种适于干旱地区和丘陵坡地的耕作新技术。蓄水聚肥改土耕作法,就是沿等高线将宽65厘米、深165厘米条带上的土壤,重新组成“种植沟”和“生土垄”(二者统称抗旱丰产沟)。种植沟深50厘米,把熟化的表土都集中在种植沟里,填满肥料,从而为作物提供了深扎根系,蓄纳雨水的条件。“生土垄”种植豆科绿肥,可拦蓄径流,挡风积雪,并使土壤熟化。抗旱丰产沟垄高沟低,作物高矮搭配,行距加大,通风透光好。地表沟垄相间,粗糙度加大,地面接受太阳光辐射面积增大,较好地解决了土、水、肥、气、热的矛盾,为作物的生长发育创造了良好条件。 Soil rehydration farming fertilizer farming practices (also known as drought-yielding tillage farming practices), is the Shanxi Provincial Institute of Soil and Water Conservation invented a suitable for arid areas and hilly slopes of tillage new technology. The method of changing water from fertilizer to fertilizer is to reorganize the soils along 65 cm and 165 cm along the contour line into “planting ditch” and “raw mound ridge” (both collectively referred to as drought-resistant ditches). Planting grooves 50 cm deep, the maturity of the topsoil are concentrated in the planting ditch, filled with fertilizer, thus providing a deep roots for crops, storage conditions of rainwater. “Raw soil ridge” planting legume green manure, can intercept runoff, wind and snow, and the soil maturation. Drought drought yield furrow ditch low, crop height collocation, spacing increases, good ventilation and light. Surface ditch and ridge, the roughness increases, the ground receives more solar radiation area, better solve the contradiction between soil, water, fertilizer, gas and heat, creating good conditions for crop growth and development.
