“丰产沟”技术乃是对旱薄地土体构型实行后就改造,以便改良土壤理化生物特性、提高土壤肥力及物能循环方向的旱集优技术.经实践,十年左右既开设旱薄地生土熟化,又能改熟地耕层增厚近一倍.从而改变了农田生态,提高地力. “Harvesting ditch” technology is a technology that improves the physical and chemical characteristics of soil and improves the soil fertility and the circulation direction of material and energy after it is implemented on the dry land. After practice, Soil aging, but also to change nearly twice as thicker plow layer, thus changing the farmland ecology, improve soil fertility.
