Embodiment 1

[0021] The present invention provides a kind of preparation method of saline-alkali soil biological improver, comprising the following steps:

[0022] Step 1: Prepare a mixture according to the weight of the following raw materials: 200 parts of livestock and poultry manure, 150 parts of humus, 80 parts of pine wood sawdust, and 50 parts of high-protein insect powder. Rotate at 1000 rpm, and after the stirring is completed, squeeze and mash the agglomerates generated by the agitation, mash the agglomerates of the mixture, and lay it flat for 2 hours to remove the peculiar smell;

[0023] Step 2: After putting into the mixing tank for stirring and mixing in sequence, the mixing tank rotates 1000 rpm / use ultraviolet irradiation method to inactivate and disinfect the bacteria in coniferous forest humus and livestock manure in the mixture, and transfer the mixture into the ultraviolet disinfection room After spreading, irradiate the mixture with ultraviolet disinfection light for ...

Embodiment 2

[0030] The present invention also provides a preparation method of a saline-alkali soil bio-improvement agent, which differs from Example 1 in that it includes the following steps: Step 1: Prepare a mixture from the following raw materials in parts by weight: 300 parts of livestock and poultry manure, humus 200 parts, 100 parts of pine wood sawdust, and 80 parts of high-protein insect powder are put into the mixing tank in turn for stirring and mixing, and the mixing tank is rotated at 1000 rpm. After the agglomeration is mashed, spread it and let it stand for 2 hours to remove the peculiar smell;

[0031]Step 2: After putting into the mixing tank for stirring and mixing in sequence, the mixing tank rotates 1000 rpm / use ultraviolet irradiation method to inactivate and disinfect the bacteria in coniferous forest humus and livestock manure in the mixture, and transfer the mixture into the ultraviolet disinfection room After spreading, irradiate the mixture with ultraviolet disin...

Embodiment 3

[0038] The present invention also provides a preparation method of a saline-alkali soil bio-improvement agent, which is different from Examples 1 and 2: it includes the following steps: Step 1: Prepare a mixture from the following raw materials in parts by weight: 250 parts of livestock and poultry manure, rotten 175 parts of soil, 90 parts of pine wood sawdust, and 70 parts of high-protein insect powder are put into the mixing tank in turn for mixing and mixing, and the mixing tank is rotated at 1000 rpm. After the mixture is agglomerated and crushed, spread it and let it stand for 2 hours to remove the peculiar smell;

[0039] Step 2: After putting into the mixing tank for stirring and mixing in sequence, the mixing tank rotates 1000 rpm / use ultraviolet irradiation method to inactivate and disinfect the bacteria in coniferous forest humus and livestock manure in the mixture, and transfer the mixture into the ultraviolet disinfection room After spreading, irradiate the mixtur...

Abstract

The invention discloses a preparation method of a saline-alkali soil biological improver, and particularly relates to the technical field of saline-alkali soil improvements, which comprises the following steps: preparing a mixture from the following raw materials in parts by weight; performing ultraviolet inactivation and disinfection; adding an organic additive; fermenting and decomposing the mixture; adding silicate and a surfactant; and screening the finish product by means of a screening machine. According to the invention, excrement of herbivorous livestock is selected; fully mixing withhumus soil, pine sawdust and high-nutrition high-protein insect powder; oxalic acid in excrement and humus soil can be used for neutralizing composite humic acid of alkali in the saline-alkali soil through strain fermentation; the leavening can increase fluffy solidification degree after silicate and surfactant are added, the solidification effect in the saline-alkali soil is guaranteed, the physical and chemical properties of the soil are improved; meanwhile, due to the action of the surfactant and pine sawdust, soil nodules can be reduced after rotary tillage, and the overall improvement effect of the saline-alkali soil is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, and more specifically, the invention relates to a preparation method of a saline-alkali soil bio-improvement agent. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares, all kinds of saline-alkali soil are formed under certain natural conditions. The essence of its formation is mainly that various soluble salts are redistributed in the horizontal and vertical directions on the ground, so that the salt is distributed in the salt-collecting area. The soil surface layer gradually accumulates. Saline-alkali soil is divided into two types of saline-alkali soil according to the salt c...
