在黄土丘陵区修筑梯田可以起到拦蓄降水、减少水土流失、改善生态环境、发展农业生产的目的。但新修梯田往往生土裸露、土壤养分含量低且易板结,水、肥、气、热不协调,导致作物生长发育状况差, The construction of terraced fields in the loess hilly areas can serve the purpose of intercepting precipitation, reducing soil and water loss, improving the ecological environment and developing agricultural production. However, newly-repaired terraces are often exposed to bare soil, soil nutrient content is low and easy to knot, water, fertilizer, gas and heat are not coordinated, resulting in poor crop growth and development,
