一、落实水土保持措施1、高标准修建梯田、围山转、鱼鳞坑,充分发挥自然生态条件下的保水保土潜能。具体方法是:25度以下的山地或丘陵地修成梯田或围山转(水平沟)。梯田面宽度随坡度增大而减小,范围在3-25m,外沿坎壁一般不超过1.5m,其上部向内倾斜,高出地面20cm。梯田可栽2行以上栗树,行间作埂,利于蓄水保墒,又防止冲垮坎壁。挖水平沟(沟深、宽各1m)时将底土放在外沿,并培
First, the implementation of soil and water conservation measures 1, high standards to build terraced fields, hills around the scale pit, give full play to the natural ecological conditions of water and soil conservation potential. The specific method is: 25 degrees below the mountain or hilly built terraced or Wai Hill turn (horizontal groove). The width of the terraces decreases with increasing slope, ranging from 3-25m. The outer ridgeline is no more than 1.5m. The top of the terraced slope slopes inwardly and is 20cm above the ground. Terraced plants can be planted more than 2 rows of chestnut trees, intercropping 埂, conducive to water and soil conservation, but also to prevent the crushing of Khan wall. Ditch horizontal trench (ditch deep, wide 1m) when the soil on the outer edge, and training
