Embodiment 1

[0031] The formula of embodiment 1 saline soil improving agent

[0032] Said saline-alkali land improving agent includes powder and water,

[0033] The powder comprises the following components by weight: 10 parts of organic bentonite, 3 parts of modified rectorite, 15 parts of organic fertilizer, 12 parts of humus, 18 parts of compound fertilizer, 7 parts of amino acid, 0.8 part of polyacrylamide, biological flora 0.5 copies;

[0034] The rectorite is ground into a fine powder with a ball mill and calcined, then organically modified with cetyltrimethylammonium bromide as an intercalation agent, and finally the modified organic rectorite is melted with polypropylene Mixed on a twin-screw screw machine to prepare modified rectorite.

[0035] The organic fertilizer is animal manure and plant straw; the compound fertilizer is a mixture of potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer in parts by weight of 2:6:8, and the biological flora includes Bacillus s...

Embodiment 2

[0038] Choose a piece of Weifang coastal saline-alkali land to plant mulberry.

[0039] Terrain finishing: finishing the saline-alkali land to be improved, and leveling the ground with high excavation and low filling, and the maximum slope is less than 12°;

[0040] Laying of hidden salt drainage pipes: Use trenching and embedding machines to lay salt drainage hidden pipes. The buried depth of the salt drainage hidden pipes is 1.5m, and the slope is 0.3‰. The effective water absorption area of ​​each meter of pipes should not be less than 31c㎡ / M, all the water inlet holes of the pipe body should be at the bottom of the trough, and the number of water inlet holes on the same circumference is 3, and there are multiple parallel underground salt discharge pipes, and the distance between the two adjacent salt discharge buried pipes is 30m , There is also a water collection pipe connected to each salt discharge hidden pipe. After the salt discharge concealed pipe and the water collec...

Embodiment 3

[0048] Choose a piece of Weifang coastal saline-alkali land and plant lawns, the species of which is Tall thatch.

[0049] Terrain adjustment: The saline-alkali land to be improved will be adjusted, and the flat land will be leveled by high excavation and low filling, and the maximum slope shall not exceed 8°.

[0050] Laying of hidden salt drainage pipes: laying hidden salt drainage pipes with a trenching pipe burying machine, the buried depth of the salt drainage hidden pipes is 0.6m, and the slope is 0.3‰. The distance between adjacent salt-discharging hidden pipes is 30m, and a water collecting pipe connected to each salt-discharging hidden pipe is also laid.

[0051] Desalinated water equipment installation: installation of brackish water purification system, said brackish water purification system includes sequentially connected raw water tanks, booster pumps, horizontal media filters, antiscalant dosing devices, security filters, high-pressure water pumps, Reverse osmo...

Abstract

The invention discloses a saline-alkali soil improving method. The method includes the steps of leveling the terrain of selected saline-alkali soil, laying salt disc elimination harge closed underground pipes, installing a bitter water desalting system to desalt crude water and collected salty water of the saline-alkali soil to provide fresh water for irrigation salt content restraining and irrigation, primarily conducting primary salt elimination on the saline-alkali soil through irrigation salt content restraining, adjusting the soil structure through a saline-alkali soil modifier, providing trace elements required by plants, planting salt-tolerant plants for further reducing salt content, conducting underground salt elimination through the combination of drip irrigation-micro jet devices and the salt-tolerant plants, and executing information maintenance management on the area of the saline-alkali soil. The method integrates biology, physics, chemistry and water conservancy methods, and is small in water resource consumption, rapid in effect, not prone to salt returning and more beneficial to plant growth.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a soil improvement method for saline-alkali land. Background technique [0002] Saline-alkali land is a kind of soil type widely distributed in the world, and it is an important land resource. The saline-alkali land area in the world is about 15 billion mu, and the saline-alkali land area in my country is about 540 million mu, accounting for one-thirtieth of the world; the saline-alkali land in my country is about 90 million mu, and the cultivated land in my country is only 1.5 billion mu, accounting for nearly one-tenth of the cultivated land area in my country. one fifth. At present, it has become the biggest obstacle restricting the construction of ecological environment and the sustainable development of agriculture in our country. At the same time, with the reclamation of large areas of land, soil salinization caused by unreasonable irrigation and wat...
