preparation example Construction

[0034] A technical method for preparing a saline-alkali soil biological amendment, the steps are as follows:

[0035] Step 1, crushing corn stalks and cotton stalks with a straw grinder.

[0036] Step 2, mixing peat fertilizer, cattle, horse and chicken animal fertilizer with bean dregs, distiller's grains, vinegar dregs and other organic fertilizers in a volume ratio of 1:1:1:1:1.

[0037] Step 3, the pulverized product of corn stalks and cotton stalks obtained in step 1, the organic waste and compound fertilizer obtained in step 2 according to the weight ratio of 65% to 78%: 20% to 30%: 2% to 10% Mix evenly; make the crushed materials of corn stalks and cotton stalks account for a large proportion of organic waste, thereby reducing the cost of modifiers, and at the same time fundamentally solve the problem of the treatment of these organic wastes, which can be reused and will not be wasted.

[0038] Step 3, adding water to the mixture in the above step 3, sealing it, fermen...

specific Embodiment 1

[0044] The site is located in Beihai Wetland Park, Binzhou, where the soil conditions before improvement are shown in the attached figure 1 , the improved soil condition after using the bio-improvement agent in the technical scheme of the present invention is shown in the appendix figure 2 .

[0045] 1. The general situation of water and soil in the place of embodiment is as follows:

[0046] Located in the northern part of Binzhou City, Shandong Province, facing the Bohai Sea in the north, it belongs to the impact plain of the Yellow River, with low terrain and high groundwater level; the soil is heavy and compacted, with a salt content between 0.5% and 1.7%. Higher; the mineralization of groundwater is high.

[0047] 2. The implementation steps are as follows:

[0048] (1) Grinding corn stalks and cotton stalks with a straw grinder; mixing peat fertilizer, ox horse chicken animal fertilizer with bean dregs, distiller's grains, vinegar dregs and other organic fertilizers in...

specific Embodiment 2

[0052] In the technical solution of the present invention, specific embodiment two is as follows:

[0053] The location is located in Xuxu New District, Lianyungang, Jiangsu.

[0054] 1. The general situation of water and soil in the place of embodiment is as follows:

[0055] Xuxu New District is located in the southeast of Lianyungang City, the soil type is mainly salinized fluvo-aquic soil, most of the land reserve resources soil salt content is between 0.4% and 2.0%, and the groundwater table is shallow, therefore, the secondary salinity of the soil The threat of waterlogging is great, and the engineering measures such as water conservancy infrastructure and water and soil conservation are not perfect. The existing drainage channels are silted up, and the drainage is not smooth, which intensifies the secondary salinization of the soil.

[0056] 2. The specific implementation steps are as follows:

[0057] (1) Grinding corn stalks and cotton stalks with a straw grinder; m...

Abstract

The present invention provides a preparation and use method of a saline-alkali soil biological improver, corn stalks and cotton stalks are crushed; a peat fertilizer, animal manure, bean dregs, lees, and vinegar residue are mixed in the volume ratio of 1:1:1:1:1 to obtain an organic fertilizer; the crushed corn stalks and cotton stalks prepared in the step 1, the organic fertilizer obtained by the step 2 and a compound fertilizer are uniformly mixed according to the weight ratio of 65-78% : 20-30% : 2-10 %; the mixture obtained in the step 3 is added with water and sealed for fermentation composting, and disinfection sterilization treatment is performed in the composting process; and when the mixture volume is reduced by 1/2, the composting is complete. The raw materials are organic manure and acidic organic waste, the saline-alkali soil biological improver can improve soil fertility, improve soil structure, reduce ground surface moisture evaporation, suppress returning salt when the saline-alkali soil biological improver is applied to a saline-alkali land, and the saline-alkali soil biological improver is conducive to the survival of microorganisms, and beneficial to living of ground cover plants, and improves the saline-alkali land ecological environment.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to a preparation method and a use method of a saline-alkali soil biological improver. Background technique [0002] my country's saline-alkali land area is nearly 100 million hectares and widely distributed, and it is increasing year by year. It is one of the world's largest saline-alkali land countries. In recent years, with the development of tidal flat reclamation and sea reclamation, an average of 285 square kilometers of sea reclamation has been newly added every year, and the continuous increase of saline-alkali land is threatening the cultivated land on which people live. Make full use of alkaline soil. The improvement of saline-alkali land in my country is mainly divided into guest soil and original soil improvement. At present, the commonly used guest soil and underground pipe drainage technology can improve the effect in a short period of time, but the project is h...
