摘要
本文通过大区对比法对浅翻深松改良低湿耕地的效果进行研究。结果表明:浅翻深松降低土壤容重.增加土壤孔隙度.提高地温.增加土壤渗透性.增强了低湿耕地的抗涝保墒能力,提高了作物产量,是低湿耕地改良的有效措施。
The improving effect of shallow ploughing and deep digging to low-wet soil was studied in this paper. The result showed that shallow ploughing and deep digging could decrease soil volume weight, increase soil porosity , raise soil temperature, enlarge soil permeability, enhance the ability of waterlogging resistance and moisture preservation of low-wet soil and increase crop yield and is a effective method to improve low-wet soil.
