AI Technical Summary

Benefits of technology

This patented technology helps prevent or decrease acidification caused by salt water used for growing crops during rainwater irrigation systems that use sea water instead of freshly mined seawater (salt). By reducing these factors, this new system reduces harmful impact on plants' roots while still maintaining good quality vegetations at their best level.

Problems solved by technology

This patented technical solution involves improving the quality and quantity of salty ground by reducing its alkality with respectable levels of mineral elements like calcium chloride, magnesia, silica, silt lime clay, ammoniacal phosphorus, nitrogen, iron oxides, manganese, chromite, copper, zinc, etc., while also addressing issues related to soil salification caused by low pH values and strong negative ion content.

Embodiment 1

[0019] Embodiment 1: The soil conditioner, raw materials include 70 to 85 parts of desulfurized gypsum, 10 to 25 parts of humic acid, 0.5 to 5 parts of magnesium sulfate, 0.5 to 5 parts of water-soluble permanent high molecular polymer and 1.0 to 10 parts of solid acid, the soil conditioner is obtained by the following preparation method: the required amount of desulfurized gypsum, humic acid, magnesium sulfate, water-soluble high molecular polymer and solid acid are mixed A soil conditioner is obtained after uniformity. The use of desulfurized gypsum, humic acid, magnesium sulfate, water-soluble polymers and solid acids can reduce the cost of improving salinized soil.

Embodiment 2

[0020] Embodiment 2: this soil conditioner, raw material comprises 70 parts by weight or 85 parts of desulfurized gypsum, 10 parts or 25 parts of humic acid, 0.5 part or 5 parts of magnesium sulfate, 0.5 part or 5 parts of water-soluble permanent high molecular polymer and 1.0 part or 10 parts of solid acid, the soil conditioner is obtained by the following preparation method: the required amount of desulfurization gypsum, humic acid, magnesium sulfate, water-soluble high molecular polymer and solid acid are mixed A soil conditioner is obtained after uniformity.

Embodiment 3

[0021] Embodiment 3: As an optimization of the above embodiments, the water-soluble polymer is more than one of polyacrylamide, polyvinyl alcohol, and polymaleic anhydride.

Abstract

The invention relates to the technical field of salinized soil conditioners and in particular relates to a soil conditioner, a preparation method thereof and a method for conditioning salinized soil on afforestation lands. The soil conditioner is obtained by the following preparation method: uniformly mixing a required amount of desulphurization gypsum, humic acid, magnesium sulfate, water-soluble polymers and solid acid. By adopting the soil conditioner and an application method of the soil conditioner, the pH value, alkalinity and total salt content of the salinized soil can be reduced, the conditioning cost of the salinized soil is reduced and the conditioning effects of the salinized soil are effectively improved, thus improving the soil texture and fertility and then increasing the seedling survival rate. The soil conditioner and the method have the function of accelerating agricultural development and ecological shelter forest construction of salinized regions.
