Problems solved by technology

The common improvement methods are mostly to apply compound fertilizers added with humic acid (such as authorized announcement number: CN103224431 B, a Chinese invention patent named "a fertilizer for preventing soil compaction and its preparation method") or to apply microbial fertilizers (such as authorized announcement No.: CN 102503699 A, Chinese invention patent and authorized announcement No.: CN 102603430 B, titled "compost tea for improving soil compaction and its preparation method" "Chinese invention patent), the above inventions all have a significant effect on preventing soil compaction, but they can still introduce a large amount of inorganic nutrient ions during use, which is likely to cause secondary compaction or acidification of the soil, and the production cost is high. , which is not conducive to large-scale promotion and application to the improvement of regional planting soil

Embodiment 1

[0017] A kind of preparation method of the bio-organic fertilizer of loose soil, prepare through the following steps:

[0018] 1. Prepare decomposing agent: drop 2 parts of Bacillus coldolyticus, 4 parts of corn flour, 6 parts of plant ash, 8 parts of cottonseed meal, 12 parts of calcium dihydrogen phosphate, 18 parts of concentration of 2 parts by weight in No. 1 fermentation tank % molasses, mixed and stirred evenly to make a decomposed mixture of strains, adding water to adjust the water content of the decomposed mixture of strains to 75%, then adding 27 parts of wheat straw, and sealing it at 25°C for anaerobic fermentation for 3 days. The oxygen-fermented material is pulverized and filtered to obtain filter residue and filtrate, and the filter residue is used for later use. Take 18 parts of filtrate, add 3 parts of activated carbon and 2 parts of EM bacterial agent, stir and mix evenly, and obtain decomposing agent;

Embodiment 2

[0024] A kind of preparation method of the bio-organic fertilizer of loose soil, prepare through the following steps:

[0025] 1. Prepare decomposing agent: drop 4 parts of Bacillus coldolyticus, 6 parts of corn flour, 8 parts of plant ash, 10 parts of cottonseed meal, 14 parts of calcium dihydrogen phosphate, 22 parts of concentration of 2 parts by weight in No. 1 fermentation tank % molasses, mix and stir evenly to make a decomposed mixture of strains, add water to adjust the moisture content of the decomposed mixture of strains to 85%, then add 32 parts of wheat straw, and seal it at 30°C for anaerobic fermentation for 5 days. The oxygen-fermented material is pulverized and filtered to obtain filter residue and filtrate, and the filter residue is used for later use. Take 22 parts of filtrate, add 5 parts of activated carbon and 3 parts of EM bacterial agent, stir and mix evenly, and obtain the decomposing agent;

experiment example 1

[0031] The beneficial effects of the present invention that can loosen farmland soil are further illustrated by the following experimental examples.

[0032] From September 2014 to April 2016, in Xiaoyi Village, Songcun Town, Wendeng District, Weihai City, Shandong Province, the soil of the tomato planting field that had already appeared hardened was selected as the test object, and the soil improvement was carried out by using the present invention for 20 consecutive months (the same time for two years). Site test), observe the actual effect of loose soil of the present invention.

[0033] Test group (area 2 mu): conventional fertilization+bio-organic fertilizer of Example 1 of the present invention

[0034] Control group (area 2 mu): conventional fertilization (CK)

[0035] Test requirements: conventional fertilization is 5,000 kilograms of fully decomposed farmyard manure per mu, 50 kilograms of superphosphate, 15 kilograms of urea, and 25 kilograms of potassium sulfate fo...

Abstract

The invention discloses a preparation method of a biological organic fertilizer for loosening soil. The preparation method has the benefits that firstly, cheap organic materials are taken as main raw materials, and a microbial strain fermentation process is adopted for preparation, and a product has the characteristics of an organic fertilizer and the biological organic fertilizer and has better soil loosening and improving effects; secondly, bacillus psychrosaccharolyticus, nitrobacteria, EM bacteria and bacillus megatherium and other microorganism rotten strains are integrated step by step through a 'three-step fermentation method', so that the strain amplification and antagonism effects caused by simultaneous fermentation of multiple strains are avoided, the effective activities of the four strains are greatly retained, and the technical effects of the invention are obviously improved; thirdly, the production cost is low, the industrial production and the large-scale application are facilitated, and the defect of high cost existing in farmland soil compaction improved by the organic fertilizer and a soil conditioning agent product which are being sold in the current market is overcome.

Description

technical field [0001] The invention relates to a method for preparing bio-organic fertilizer, in particular to a method for preparing bio-organic fertilizer for loose soil, and belongs to the technical field of fertilizer production. Background technique [0002] In agricultural production, due to the lack of organic matter in the surface layer of the long-term cultivated soil, the structure is poor, and the aggregate structure is destroyed under the action of external factors such as irrigation or rainfall, and the soil material is dispersed. After drying, the soil surface is hardened by the cohesive force. In addition, long-term application of single chemical fertilizers will not replenish organic matter in time. Only cations or anions in chemical fertilizers are the elements needed by plants. Plants unilaterally choose to absorb useful ions, and the remaining ions react with calcium and magnesium ions in the soil to form Insoluble substances destroy the soil aggregate st...
