Problems solved by technology

[0002] Saline-alkali land refers to the general name of various types of soils that contain too much saline-alkali components in the soil, including saline soil and alkaline soil, and other types of soil that have undergone a certain degree of salinization or alkalization. Saline soil refers to a large amount of soluble salts that make most plants Soil that cannot grow. Alkaline soil refers to the soil where the percentage of substitutable sodium ions accounts for more than 20% of the cation replacement capacity and the pH value exceeds 8. In fact, because saline soil and alkaline soil are often interlaced, it is customary to collectively call them saline-alkali soil. , saline-alkali land is more harmful, mainly manifested in restricting agricultural production, destroying the ecological environment and affecting sustainable development; saline-alkali land improvement has always been one of the important topics of concern and research by workers in related fields. Ecological environment and the promotion of agricultural economic development; the use of existing saline-alkali land improvement fertilizers to avoid further deterioration of saline-alkali soil, use organic fertilizers to increase the fertility of saline-alkali land and improve the physical and chemical properties of saline-alkali soil, but the existing organic fertilizers are insufficiently fermented, resulting in microbial Insufficient decomposition of crude organic matter, sugars, protein cellulose and lignin in organic fertilizers results in small effective organic matter content, slow release of inorganic nutrients such as nitrogen, phosphorus and potassium in organic fertilizers, and residues of pathogenic bacteria and parasite eggs can easily make crops sick And other phenomena, eventually lead to the improvement effect of saline-alkali land is not obvious, need further improvement

Embodiment 1

[0017] 1) Chopped 28 parts of straw and 25 parts of rotten grass, with a length of 1 cm, and set aside;

[0018] 2) Mix and granulate 15 parts of urea, 13 parts of superphosphate, 7 parts of potassium sulfate and 2 parts of trace elements, and set aside;

[0019] 3) Mix 40 parts of sheep manure with the straw and rotten grass prepared in step 1), add distilled water to 0.1 part of microbial inoculum for dilution, the volume ratio of microbial inoculum to distilled water is 1:200, and dilute the diluted The microbial agent is evenly sprayed on the mixture, and then 6 parts of corn flour are added to the mixture for composting and fermentation. The fraction is 8%-20%, and the fermentation time is 8 days;

[0020] 4) Mix the fertilizer granules prepared in step 2) and the fermented fertilizer prepared in step 3) evenly, and apply them to saline-alkali soil.

Embodiment 2

[0022] 1) Chopped 31 parts of straw and 27 parts of rotten grass, the length is 2cm, set aside;

[0023] 2) Mix and granulate 17 parts of urea, 15 parts of superphosphate, 9 parts of potassium sulfate and 3 parts of trace elements, and set aside;

[0024] 3) Mix 43 parts of cow dung with the straw and rotten grass prepared in step 1), add distilled water to 0.2 parts of microbial inoculum for dilution, the volume ratio of microbial inoculum to distilled water is 1:200, and dilute the diluted The microbial agent is evenly sprayed on the mixture, and then 9 parts of corn flour are added to the mixture for composting and fermentation. The fraction is 8% to 20%, and the fermentation time is 10 days;

[0025] 4) Mix the fertilizer granules prepared in step 2) and the fermented fertilizer prepared in step 3) evenly, and apply them to saline-alkali soil.

Embodiment 3

[0027] 1) Chopped 34 parts of straw and 30 parts of rotten grass, the length is 2cm, set aside;

[0028] 2) 18 parts of urea, 16 parts of superphosphate, 12 parts of potassium sulfate and 4 parts of trace elements are mixed and granulated, and set aside;

[0029] 3) Mix 47 parts of pig manure with the straw and rotten grass prepared in step 1), add distilled water to 0.2 parts of microbial inoculum for dilution, the volume ratio of microbial inoculum to distilled water is 1:200, and dilute the diluted The microbial agent is evenly sprayed on the mixture, and then 12 parts of corn flour are added to the mixture for composting and fermentation. The fraction is 8% to 20%, and the fermentation time is 12 days;

Abstract

The invention relates to the technical field of saline-alkali soil improvement, in particular to a fertilizer for improving saline-alkali soil. The fertilizer comprises the following raw materials inparts by weight: 40-50 parts of manure, 28-37 parts of straw, 25-32 parts of gymnosiphon nana, 15-20 parts of urea, 13-18 parts of calcium superphosphate, 7-15 parts of potassium sulfate, 6-15 parts of corn flour, 2-5 parts of trace elements and 0.1-0.3 part of a microbial agent. Through the control of a fermentation condition and the addition of the microbial agent and the corn flour, microorganisms can sufficiently decompose crude organic matters, saccharides, protein cellulose and lignin in an organic fertilizer to ensure that the effective organic matter content is large, pathogenic bacteria and parasitic ovums are effectively killed, the soil fertility is improved by combining quick-acting nitrogen, phosphorus and potassium and trace elements, and the saline-alkali soil is effectivelyimproved.
