坡改梯与聚土垄作一步到位法,即在紫色页岩发育的坡度为5—25度的坡耕地上,按坡度大小确定出梯地宽窄,然后在将坡地降为梯地的同时,把肥土与底岩各聚一垄,再在垄上种植适宜作物的办法。它把坡改梯、聚土垄作、增厚土层、减少水土流失等多道工序在一次作业中完成,是建设稳产高产农田的好办法。具体作法是: 1、确定梯地宽度。根据坡度大小沿水平线放,坡度小的梯地可放到5米左右宽。坡度大的梯地可按3.3米左右宽进行。
Pitch to change the ladder and the soil ridge for a one-step law, that is purple shale slope of 5-25 degrees of cultivated sloping land, according to the size of the slope to determine the width of the staircase, and then the slope down to the ladder at the same time, Fertile soil and rock each gather a ridge, and then planted suitable crops in the ridge approach. It is a good way to build a stable and high-yield farmland in a single operation, which consists of multi-channel operations such as changing slopes to slopes, gathering soil and ridge, thickening soil layers and reducing soil and water loss. Specific practices are: 1, to determine the width of the ladder. According to the size of the slope along the horizontal line, a small gradient can be put on the ladder about 5 meters wide. Large slope of the ladder can be about 3.3 meters wide.
