Problems solved by technology

[0002] Our country has a vast area of ​​saline-alkali land, among which the soil in the saline-alkali land in the coastal area is mainly weak saline soil and medium saline soil, because the saline soil contains more salt ions, most of the crops cannot survive normally

Embodiment 1

[0020] A kind of coastal saline-alkali land soil improvement technology, comprises the following steps:

[0021] Step 1: wash the salt with fresh water, dig ditches and ditches reasonably according to the terrain, use the accumulated fresh water to wash the salt in the saline-alkali land that needs to be improved, and remove most of the saline-alkali dissolved in water;

[0022] Step 2: Plow the land. In the spring and autumn, deep plow the coastal saline-alkali land, plow the soil with relatively high salt content in the subsurface to the surface, kill bacteria and insects, and clear and bury weeds;

[0023] Step 3: Irrigate the water-soluble compound fertilizer, wash the diluted concentrated sulfuric acid and potassium sulfate compound fertilizer into the saline-alkali land that needs to be improved, and soak for 30 days;

[0024] Step 4: Let it stand in the sun for 10 days, and detect the chloride ions in the soil. When the chloride ions in the soil are ≥ 300g / kg, repeat st...

Abstract

The invention relates to the technical field of saline-alkali soil improvement, and provides a coastal saline-alkali soil improvement technology. According to the method, fresh water is subjected to salt leaching, land is ploughed, the land is irrigated with a water-soluble compound fertilizer, the land is aired and stands still, an ammonium bicarbonate compound fertilizer and a potassium sulfatecompound fertilizer bacterial fertilizer are dissolved in water, and a composite microbial agent and human and animal manure are evenly mixed and applied to to-be-improved saline-alkali soil accordingto a certain weight, so that the aims of reducing the soil alkalinity, improving organic matter and being more beneficial to crop planting can be achieved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to a coastal saline-alkali soil improvement technology. Background technique [0002] The area of ​​saline-alkali land in my country is vast, and the soil in saline-alkali land in coastal areas is mainly weak saline soil and medium saline soil. Because saline soil contains more salt ions, most crops cannot survive normally. [0003] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote s...
