中国西部的很多地区因一种民众普用的砂田种植技术培育出甘甜可口的瓜果,并使黄河蜜等瓜果成为甘肃的特色优质产品砂田是我国一种古老的抗旱栽培方式。近年来随气候干旱化趋势的加重和水资源短缺的影响,该项技术受到越来越多的重视。研究表明砂石和覆盖能有效的减少土壤的蒸发,提高土壤水分,增加砂田作物产量和水分生产率。
Many areas in western China have cultivated sweet and savory fruits and melons as a result of a popular planting technique in the field of saplings and made the Yellow River honey and other fruits become the featured high-quality products in Gansu. The sands are an ancient drought-resistant cultivation method in China. In recent years, with the aggravating trend of climate aridification and the impact of water shortage, the technology is receiving more and more attention. Studies have shown that gravel and cover can effectively reduce soil evaporation, increase soil moisture and increase crop yield and water productivity in the field.
