Disclosure of Invention
The invention aims to provide a method for improving coastal saline soil, which solves the problem of planting greening plants in coastal beach saline land by using a soil dressing method at present.
The idea of the invention is that. The method for improving the coastal beach salt land is provided by utilizing industrial solid wastes such as steel slag, desulfurized gypsum, waste dust bags and the like in a steel mill and combining with organic wastes in agriculture, forestry waste branches, cattle and sheep manure and other agriculture, forestry and animal husbandry systems. The key technology is as follows: 1) digging a pit: the depth of the soil profile is determined according to the requirements of the planted plant root system, and is generally controlled to be 50-100 cm. 2) Blocking soil capillaries: coarse steel slag with the grain size of about 3mm is paved in a soil pit with the grain size of about 100cm, or a shallow underground water level is directly paved at a critical layer of the underground water level, and the effect of the coarse steel slag is to block soil capillaries so as to prevent salt in the underground water from being transported to the ground surface along with water. 3) Soil separation cloth: waste dedusting cloth or geotextile is laid on the coarse steel slag, so that the improved soil laid on the upper layer is prevented from leaking downwards and blocking gaps of the steel slag, salt in the underground saline water is moved upwards to the ground surface after the soil capillary is communicated, and fresh water in irrigation of greening plants is not prevented from being sprayed to the underground water. 4) Fermenting the organic material and the desulfurized gypsum: organic materials and desulfurized gypsum are fermented together, so that organic acid substances generated during decomposition of the organic materials are combined with calcium ions to form organic calcium salts, the solubility of calcium is increased, and after the organic compounds of calcium are mixed with saline soil, the sodium ions in the saline soil are replaced by the calcium ions, so that the aggregate structure of the soil is improved. 5) Improving the air permeability of soil: the mud flat saline soil texture is sticky, clay particles smaller than 0.01mm are mainly used in the soil mechanical composition, and the soil permeability is poor. Therefore, the fermented organic matter, the saline soil and part of the fine steel slag with the grain diameter of about 1-3mm are mixed to increase the permeability of the soil, thereby achieving the purpose of improving the physical properties of the soil. When organic materials are fermented, the enzyme bacteria are added to mainly contribute to mineralization and degradation of the organic materials and organic matters applied to soil, and the bacillus is added to mainly contribute to building a good soil microbial area system to facilitate plant growth.

(4) blocking soil capillary, preventing underground salt from moving upwards and upper soil from moving downwards
① the coarse steel slag with a grain size larger than 3mm is laid at a position 100-150cm away from the ground surface, the specific laying thickness is determined according to the soil thickness required by the growth of the root system of the planted plant, the laying thickness is 30-50cm, or in the region with shallow underground water level, the coarse steel slag is laid at the critical position of underground water to block the capillary of the soil and prevent the salt of the underground water from moving to the ground surface along with the water.
② waste dedusting cloth or geotextile is placed on the coarse steel slag, and the joints need to be lapped with each other to prevent the fine soil of the improved soil laid on the cloth from moving downwards and blocking the gap between the steel slag, and then the capillary tube of the soil is communicated;
(5) reconstructed improved soil body
And C materials are laid on the waste dust removing cloth, wherein the laying thickness is 40-100cm, and the laying thickness is 5-10cm higher than the ground surface, so that the soil is prevented from sinking to a height lower than the ground surface.
