Problems solved by technology

The existing organic vegetable production mainly uses organic manure after aerobic composting of livestock and poultry manure and crop stalks. Although it meets the basic requirements for organic vegetable cultivation, it has low available nutrients, no biologically active substances, and low number of beneficial viable bacteria. and other problems, resulting in low yield and quality decline of organic vegetables, and organic vegetables are mostly planted continuously and densely, often accompanied by problems such as soil-borne diseases

specific Embodiment 1

[0024] (1) Mixing and composting

[0025] Mix 250Kg of cow dung (by dry weight), 40Kg of wheat straw (by dry weight), 150Kg of biogas residue (by dry weight), and 10Kg of soybean meal (by dry weight), and add 10 times biogas slurry dilution Adjust the moisture content of the compost to 55% for aerobic composting. The temperature monitoring showed that the pile rose to above 50°C after 16 hours and continued until the 7th day. On the 5th day, the pile was turned over and biogas slurry was added to make the moisture content of the pile equal to 50%.

[0026] (2) Inoculation of nitrogen-fixing, phosphorus-dissolving and potassium-dissolving functional bacteria

[0027] On the 9th day, the temperature of the pile dropped below 45°C, turned over and inoculated with 2.5L OD 600 =0.8 Pseudomonas fluorescens (CGMCC deposit number: 5631). On the 14th day, turn over and inoculate with 3L OD 600 =0.8 Pseudomonas chlororaphis (Pseudomonas chlororaphis, CGMCC deposit number: 5628), whi...

Abstract

A bioorganic fertilizer used for planting organic vegetables comprises, by mass, 25-30% of animal night soil, 4.0-6.5% of crop straws, 1.0-1.5% of soybean meal, 10-15% of biogas residues, and 55% of a 10-times biogas slurry dilution solution. The invention also provides a preparation method of the bioorganic fertilizer. The method comprises the following steps: mixing the animal night soil, the crop straws, the soybean meal and the biogas residues in proportion, adding the 10-times biogas slurry dilution solution to adjust the water content of the above obtained material to 55%, uniformly stirring to obtain a pile body, fermenting, cooling, inoculating a phosphorus decomposing bacterium in proportion, inoculating a potassium decomposing bacterium 4d later, and inoculating an azotobacterium 9d after inoculation of the phosphorus decomposing bacterium; respectively overturning 4d after composting and in the inoculation of bacterial strains, and adding tap water to adjust the water content of the pile body to 45-50%; and allowing composting to be carried out for 25d to obtain a decomposed compost which can be used to plant organic vegetables as a fertilizer. The bioorganic fertilizer can enhance the soil fertility, improves the output and the quality of the vegetables, and prevents soil borne diseases.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizers, in particular to a bio-organic fertilizer used for planting organic vegetables and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the market demand for green food and organic food is increasing. Organic vegetable cultivation has become a sunrise industry with great development potential. Since the use of artificially synthesized pesticides, fertilizers, herbicides, and growth regulators is not allowed in the cultivation of organic vegetables, the fertilizers used in organic vegetables are also different from conventional vegetables, and their requirements are higher than those of conventional vegetable production. The existing organic vegetable production mainly uses organic manure after aerobic composting of livestock and poultry manure and crop stalks. Although it meets the basic requirements for organic ...
