Abstract

The invention relates to a soil improver and an improvement technology, and specifically discloses a saline-alkali soil improver. The saline-alkali soil improver is prepared from the following components of an alkalinity reducing agent, a structural agent and a synergist. The invention also discloses a saline-alkali soil improver applying technology. The saline-alkali soil improver applying technology comprises the following steps of spraying the alkalinity reducing agent, the structural agent and the synergist along with water irrigation. The invention also discloses a saline-alkali soil comprehensive improvement technology. The saline-alkali soil comprehensive improvement technology comprises the following steps: an underground water control measure, a desalting measure, an improver dosage determination measure and a technological process. The saline-alkali soil improver disclosed by the invention is rich in source of raw materials and simple in applying technology. After saline-alkali soil is improved by utilizing the saline-alkali soil improver and the saline-alkali soil comprehensive improvement technology, which are disclosed by the invention, a soil pH (Potential of Hydrogen) value, the alkalization degree and the total salt content are all obviously reduced, the soil physical and chemical properties are obviously improved, and the land productivity after 1 to 2 years can reach the level of local middle-yield fields.

Description

technical field [0001] The invention relates to a soil improver and an improvement process, in particular to a saline-alkali soil improver and a saline-alkali comprehensive improvement process. Background technique [0002] Domestic improvement methods for saline-alkali soil are roughly summarized as follows: (1) chemical improvement: application of desulfurized gypsum, phosphogypsum, superphosphate, various organic acids, etc.; (2) physical improvement: leveling the land, raising the terrain, deep plowing (3) Biological improvement: planting salt-tolerant and salt-absorbing plants, such as rice, etc. [0003] The above method has a certain application value for the improvement of saline-alkali land. For example, in the improvement of saline-alkali land in the Hetao area, leveling the land, raising the terrain, deep plowing, irrigation and washing of saline-alkali, and planting saline-alkali-tolerant plants all have some effects. In addition, the use of desulfurized gypsum ...
