| 摘要: |
| 河套灌区由于气候及多年来的灌排条件等因素,造成土壤盐碱化及次生盐碱化严重,不同程度的盐碱地在灌区内大面积呈补丁状分布,严重影响和制约着灌区农业的高效和可持续发展。本文根据灌区内盐碱地的一些特点,经过试验研究,提出了磷石膏混合法改良盐碱地的方法,并在实地经过实施验证,收到了良好的效果。 |

| Abstract: |
| Because of climate and irrigation and drainage conditions, soil salinization and secondary salinization are serious problems in the Hetao Irrigation District. Saline-alkali land of different degrees distributes patchy in a large area of the irrigation area, which seriously affects and restricts the high efficiency and sustainable development of agriculture. According to the characteristics of saline-alkali land in irrigation area, this paper puts forward a type of saline-alkali land modification by phosphogypsum mixing method through experimental study, which has been validated in the field and achieved good results. |
