Embodiment 1

[0033] A kind of saline-alkali resistant long-term stable fertilizer, the composition of the fertilizer raw materials is as follows in parts by weight: 30 parts of fermented cow dung, 30 parts of desulfurized gypsum, 4 parts of chitin, 3 parts of seaweed, 5 parts of natural woody peat, 20 parts of nitrogen fertilizer, 0.3 parts of urease inhibitor, 0.8 part of nitrification inhibitor, 3 parts of diatomaceous earth, 20 parts of phosphate fertilizer, 20 parts of potassium fertilizer, 0.6 part of zinc sulfate, and 0.6 part of borax.

[0034] The preparation method of the salt-alkali resistant long-acting stable fertilizer, the specific steps are as follows:

[0035] S1: raw material pretreatment

[0036] The fermented cow dung is obtained by adding 0.03% of the total weight of the starter bacteria to cow dung, straw or fungus residue at a ratio of 1:2, and finally air-dried, pulverized and sieved to 60 mesh.

[0037] The stalks are corn stalks with a particle size of ≤0.5cm.

Abstract

The invention relates to a saline-alkali-resistant long-effect stable fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 30 to 50 parts of fermented cow dung, 20 to 30 parts of desulphurization gypsum, 3 to 6 parts of chitin, 3 to 6 parts of algin, 1 to 5 parts of natural wood peat, 15 to 35 parts of nitrogen fertilizers, 0.1 to 0.6 part of urease inhibitors, 0.5 to 1.2 parts of nitrification inhibitors, 1 to 5 parts of kieselguhr, 15 to 25 parts of phosphatic fertilizers, 15 to 25 parts of potash fertilizers, 0.4 to 1 part of zinc sulfate and 0.4 to 1 part of borax. The saline-alkali-resistant long-effect stable fertilizer integrates the soil improvement and the fertilizer supply; the soil salt damage can be reduced; the soil structure can be improved; the soil fertility level can be improved; the problem that the continuable utilization is influenced due to serious saline damage and low fertility of the soil can be solved.

Description

technical field [0001] The invention relates to a saline-alkali resistant long-acting stable fertilizer and a preparation method thereof, belonging to the field of agricultural fertilizers. Background technique [0002] Saline-alkali land is a general term for various saline soils and alkaline soils, as well as other types of soils with different degrees of salinization and alkalization. When the accumulation of water-soluble salts in the soil surface or sub-surface layer exceeds 1-2g / kg or the alkalization degree of the soil alkalization layer exceeds 5%, the soil belongs to the range of saline-alkali land. According to statistics from the second national soil census, on the premise of excluding coastal beaches, the area of ​​saline soil in my country is 34.87 million hectares, about 520 million mu. With the decrease of cultivated land in our country, it is of great significance to rationally develop, transform, utilize saline-alkali land, and tap its production potential ...
