在干旱半干旱地区,选择坡度缓、土层厚的荒坡、荒地,挖抗旱丰产坑,具有蓄水抗旱、增温保摘,加深耕层,集中施肥,防止水土流失等综合功能,是在干旱荒坡地上建设高产稳产农田的一个途径,具体做法是:丰产坑行距、坑距均为1米,坑直径为70厘米,坑深50厘米。挖坑时先撤掉熟土,用生土筑埂,坑挖好后将熟土还回坑里。每
In the arid and semi-arid regions, the comprehensive functions of waterlogging, warming preservation, deepening of tillage, intensive fertilization and prevention of water and soil loss are selected Arid wasteland on the ground to build high and stable yield of farmland a way, the specific approach is: high yield pit spacing, pit distance is 1 m, pit diameter of 70 cm, pit depth of 50 cm. When digging first remove the cooked soil, with raw soil building 埂, digging well will be back to the pit after the cooked soil. each
