High saline-alkali soil biological treatment method

Abstract

The invention provides a high saline-alkali soil biological treatment method and belongs to the technical field of agricultural production. The PH value of a rice saline-alkali farmland is detected before rice seedlings are transplanted, a moderate solodization fertilizer is applied to the farmland uniformly and then enters soil through rotary tillage if the pH value is between 8.5-9, and then the rice seedlings are transplanted; and a high solodization fertilizer is applied to the farmland uniformly and then enters soil through rotary tillage if the pH value is between 9-12.5, water in the farmland is drained, the moderate solodization fertilizer is applied to the farmland uniformly, and then the rice seedlings are transplanted, wherein the high solodization fertilizer is produced by mixing silicic acid minerals and bauxite, and the moderate solodization fertilizer is produced by mainly utilizing silicic acid minerals, microbe organic fertilizers, fulvic acid, furfural-residue and trace-element fertilizers. The method can be used for changing the clay structure of saline-alkali soil, forming a 40-cm plant growing layer on the surface of the saline-alkali soil, preventing the secondary alkali return of high-degree saline-alkali soil and preventing hydrogen sulfide poisoning of rice caused by using an organic fertilizer and a microbial fertilizer.

Description

technical field

[0001] The invention belongs to the technical field of agricultural production and relates to a method for improving farmland soil. Background technique

[0002] The current method of treating rice saline-alkali farmland generally adopts the traditional method of washing salt and pressing alkali with large water, which requires sufficient water source, and it will cause secondary alkali return for severe saline-alkali land, and the effect is not ideal. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a biological treatment method for highly saline-alkali land.

[0004] The scheme that the present invention solves technical problem adopts the following steps to realize:

[0005] 1. Detect the pH value of rice saline-alkali farmland before rice transplanting;

[0006] 2. If the pH value is between 8.5-9, evenly spread moderate alkali-controlling fertilizers on the farmland, with an amount of 50-75 ...

Examples

Embodiment Construction

[0024] Example 1. Before rice transplanting, the PH value of the rice saline-alkali farmland was detected to be 9, and the moderate alkali-controlling fertilizer was uniformly applied to the farmland, with an amount of 75 kg per mu, and then rotary tillage was inserted into the soil, and then transplanted, and the farmland was managed after transplanting The method is the same as the existing management method. The moderate alkali control fertilizer is made of silicate mineral soil, microbial organic fertilizer, fulvic acid, ferrous sulfate, zinc sulfate, amino acid, furfural slag and potassium sulfate. , the weight and number ratio of its raw materials is:

[0026]

[0027] Example 2. Before rice transplanting, the pH value of the rice saline-alkali farmland was detected to be 10, and the highly alkali-controlling fertilizer was evenly applied to the farmland, with an amount of 35 kilograms per mu, and then rotary tillage was inserted into the soil, and then the...
