Problems solved by technology

In my country's agriculture, inorganic chemical fertilizers are mostly used to increase the yield of crops. Long-term large-scale application of chemical fertilizers solves the problem of food quantity and increases economic income, but at the same time destroys the structure of the soil, causing serious soil acidification and compaction. Especially in land degraded areas, the original soil fertility base is poor, which will lead to more compacted soil, lower fertilizer utilization rate, unbalanced soil nutrition and reduced fertility

preparation example Construction

[0028] A preparation method of an attapulgite-based organic soil conditioner, comprising the steps of:

[0029] A. Crushing

[0030] Break attapulgite into particles;

[0031] B. Mixed fermentation

[0032] Attapulgite, livestock manure and starter are mixed and stacked for fermentation;

[0033] C. Washing and drying

[0034] Introduce clean water into the fermented mixture and wash 3-5 times, then dry to constant weight;

[0035] D. Second crushing

[0036] Pulverize the mixture dried to constant weight;

[0037] E. Granulation

[0038] The mixture powder is granulated to produce finished products.

[0039] The fermentation time in the step B is 30 days, and the fermentation temperature is 55-60° C. for 7-15 days.

Embodiment 1

[0041] An attapulgite-based organic soil conditioner, comprising 2 parts of attapulgite, 5 parts of livestock manure, and 0.5 part of a starter, consisting of the following ingredients by weight: the starter is selected from bacillus, actinomycetes, saccharomyces and filamentous fungi mixed with microorganisms. The livestock manure is chicken manure, and the moisture content of the chicken manure is 20-30%.

Embodiment 2

[0043] An attapulgite-based organic soil conditioner, comprising 3 parts of attapulgite, 6 parts of livestock manure, and 1 part of a starter, consisting of the following ingredients by weight: the starter is selected from bacillus, actinomycetes, saccharomyces and filamentous fungi mixed with microorganisms. The livestock manure is chicken manure, and the moisture content of the chicken manure is 20-30%.

Abstract

The invention belongs to the technical field of soil fertilizers and particularly relates to an attapulgite based organic soil conditioner and a preparation method of the attapulgite based organic soil conditioner. The soil conditioner is used for improving the soil. The attapulgite based organic soil conditioner is prepared by mixing attapulgite, excrement of animals, and a leavening agent, and the leavening agent is mixed from the microorganisms of bacillus, actinomyces, saccharomycetes and filamentous fungi. The leavening agent adopts various beneficial microorganisms and various extracellular enzymes to achieve the effects of raising the temperature, deodorizing, eliminating plant diseases and insect pests and improving nutrients. The attapulgite has the characteristics of high specific surface area and high porosity, the activity and the adsorptive property are both greatly improved, the organic pollutants and the toxic harmful heavy metals are adsorbed, the biotoxicity and the mobility of the soil pollutants are reduced, and the bio-availability of the heavy metals is reduced.

Description

technical field [0001] The invention belongs to the technical field of soil fertilizers, and in particular relates to an attapulgite-based organic soil conditioner and a preparation method thereof. The soil conditioner is used for soil improvement. Background technique [0002] my country is a big agricultural country, owning 10% of the world's arable land and consuming 30% of the world's chemical fertilizers. In my country's agriculture, inorganic chemical fertilizers are mostly used to increase the yield of crops. Long-term large-scale application of chemical fertilizers solves the problem of food quantity and increases economic income, but at the same time destroys the structure of the soil, causing serious soil acidification and compaction. Especially for land degraded areas, the original soil fertility base is poor, which will lead to more compacted soil, lower fertilizer utilization rate, loss of soil nutrition balance, and decreased fertility. [0003] Attapulgite is ...
