梯田田面采用微集流聚肥改土耕作法，经济效益明显高于常规耕作法。大旱之年作物基本不减产，一般年份可使作物增产１５９％～２２０％，集流效率达到７０％；对于不同的粮食作物，土壤水分利用率提高１７０％～２２４％，肥料利用率提高２７．９％。同时，在梯田上采用微集流聚肥改土耕作法枣、经、菜立体间作套种模式，使得种植蔬菜的纯收益比种植粮食作物增加 ２．２６万元／ｈｍ２，其经济效益比种植一般作物提高 ３３５％，每元投资产值相应提高 １５７％。 Terraced fields using micro-stream enrichment fertilizer and tillage farming method, the economic efficiency was significantly higher than the conventional tillage method. In the dry year, the crop basically does not reduce production, the general year can increase the yield by 159% ~ 220% and the current collection efficiency by 70%. The soil water use efficiency increases by 170% ~ 224% and the fertilizer utilization rate by 27% for different crops .9%. At the same time, the use of micro-flow in the terraced fields gather jujube jujube, intercropping, intercropping intercropping mode, making the net income of vegetable cultivation than the planting of food crops increased 22,600 yuan / hm2, the economic benefits than the general planted The crop increased by 335% and the investment value per unit increased by 157% accordingly.
