Embodiment 1

[0030] Example 1: Comparison of the application of saline-alkali land biological improvement fertilizer in the demonstration field of Tianjin Nangang Industrial Zone

[0031] The formula of the improved fertilizer adopted is:

[0032]

[0033]

[0034] The above raw materials are pulverized, mixed and stirred uniformly according to the above ratio, and processed into fertilizer in powder form.

[0035] The application method is: flat application

[0036] After the saline-alkaline soil is washed with salt, the salt content will be less than 3‰, spread 10 cm on the surface, and use a rotary tiller to plow about 30 cm until the soil and fertilizer are evenly mixed.

[0037] The comparison of the results before and after application is shown in Table 1:

[0038] Comparison of application of bio-improved fertilizers for saline-alkali land in demonstration fields in Nangang Industrial Zone

[0039] (Table I)

[0040]

Embodiment 2

[0041] Example 2: Comparison of application of saline-alkali land biological improvement fertilizer in demonstration fields of Tianjin Lingang Industrial Zone

[0042] The formula of the improved fertilizer adopted is:

[0043]

[0044] The above raw materials are pulverized, mixed and stirred uniformly according to the above ratio, and processed into fertilizer in powder form.

[0045] The application method is: flat application

[0046] After the saline-alkali soil is washed with salt, the salt content is reduced to less than 3‰, spread 10 cm on the surface, and use a rotary tiller to plow about 30 cm until the soil and fertilizer are evenly mixed.

[0047] The comparison of the results before and after application is shown in Table 2:

[0048] Comparison of biological improvement fertilizers applied to saline-alkali soil in demonstration fields in Lingang Industrial Zone

[0049] (Table II)

Embodiment 3

[0051] Example 3: Comparison of application of saline-alkali soil bio-specific improved fertilizers in Jiangsu Dafeng Peninsula Hotel engineering soil

[0052] The formula of the improved fertilizer adopted is:

[0053]

[0054] The above raw materials are pulverized, mixed and stirred uniformly according to the above ratio, and processed into fertilizer in powder form.

[0055] The application method is: flat application

[0056] After the saline-alkali soil is washed with salt, the salt content is reduced to less than 3‰, spread 10 cm on the surface, and use a rotary tiller to plow about 30 cm until the soil and fertilizer are evenly mixed.

Abstract

The invention relates to a biological improving fertilizer special for saline-alkali soil and a preparation method thereof, wherein the improving fertilizer comprises the following components according to parts by weight: 30-50 parts of grass carbon, 10-30 parts of pine needle, 20-50 parts of cow dung, 10-35 parts of NovoGro, 5-10 parts of phosphate fertilizer, 5-10 parts of nitrogenous fertilizer and 10-30 parts of desulfurized slag or sulphur. The invention also provides a preparation method and application method of the improving fertilizer; the invention is mainly applied to soil improvement, fertilization and solodization of the saline-alkali soil after salt exclusion, and can activate soil and increase the total nutrient and organic matter content of soil. The improving fertilizer can promote the addition of a crumb structure of soil, improves the particle capillarity function of the soil, improves soil permeability, loosens the soil, enhances and rises earth temperature, and accelerates and promotes the infiltration capability and the drain function.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special bio-improvement fertilizer mainly used in the improvement and repair of various saline-alkali lands such as coastal saline-alkali land, inland saline-alkali land, and secondary salinization, and a preparation method thereof. Background technique [0002] At present, international and domestic saline-alkali soil improvement techniques can be summarized as follows: (1) physical improvement: leveling the land, deep plowing and sunning, loosening the soil in time, raising the terrain, and improving the soil in micro-area; (2) water conservancy improvement: supporting drainage and irrigation, (3) Chemical improvement: gypsum, phosphogypsum, superphosphate, humic acid, peat, vinegar residue, etc.; (4) Biological improvement: planting rice, planting salt-tolerant plants Wait. At present, the improvement of saline-alkali soil is mostly through replacing the soil and then planting plants. This i...
