九三农管局所属各农场地处黑土带地区,地形为丘陵慢岗,加上以往沿袭传统顺坡耕种方法,造成水土超限量流失,黑土层厚度由原来的60～100厘米减至30～60厘米。冲刷沟已有1649条,总长度为63.8万米,损坏耕地面积2.9万亩。为了防止冲刷,九三农管局基建水利处,采用回填—砌垡—插柳一次性快速治理冲刷沟法,经过1984～1988年5年的试验结果证明,此法是成功的,它为 Ninety-three of the farmhouse owned farms are located in the black soil zone, the terrain for the hilly slow Kong, coupled with the traditional inherited the traditional slope farming methods, resulting in excess soil and water loss, black soil thickness from the original 60 to 100 cm to 30 ~ 60 cm. Scouring ditch has 1649, the total length of 638000 meters, 29000 acres of damaged farmland. In order to prevent scouring, the infrastructure construction water conservancy department in 1993, using backfill - brickwork - plugging Liu rapid one-time erosion scour control method, after 1984 to 1988 five years of test results show that this method is successful, it is
