Problems solved by technology

Many research results have proved that the application of bio-organic fertilizer is a simple and effective method to solve soil degradation and continuous cropping obstacles, but there are currently two problems: ①Short shelf life: the shelf life of domestic bio-organic fertilizers is usually only 6 After storage, transportation, sales and other links, the shelf life is often past when used, and most of the strains have been inactivated before use, and the use effect is not good (that is, the effect is often good in research experiments, but the actual application effect in production is not good. bad phenomenon); ② Insufficient dosage: due to the high price of bio-organic fertilizers, the dosage is often insufficient (usually the dosage per mu will not exceed 50kg), and it is not easy to form dominant bacteria in the soil
[0004] 1. It can only play the role of ordinary organic fertilizer, such as improving soil and improving soil fertility. In addition to the effect of ordinary organic fertilizer, bio-organic fertilizer also has the functions of disease resistance, activation of soil nutrients, nitrogen fixation, and promotion of plant growth. , prevention and control of continuous cropping obstacles and other functions;
[0005] 2. Low value, the price of ordinary organic fertilizer is below 500 yuan / ton, while the price of bio-organic fertilizer per ton is more than several thousand yuan

Embodiment 1

[0025] Embodiment 1, a kind of utilization CO in the field 2 The method for directly composting bio-organic fertilizer from fertilization and fermentation residues involves the following steps in sequence:

[0026] 1) Adjust the water content in the fermentation waste residue to 60% (% by weight), and use the above-mentioned fermentation residue after adjusting the water content as the fermentation substrate; take 1000kg of fermentation substrate for use;

[0027] 2) Mix 5kg of disease-resistant strains (Jiangsu Xintiandi Biological Fertilizer Engineering Center Co., Ltd.) with 15kg of water to obtain a bacterial agent mixture;

[0028] 3) Spray the bacterial agent mixture obtained in step 2) evenly on the 1000kg fermentation substrate obtained in step 1), and stir and mix evenly while spraying;

[0029] 4) Stack the results of step 3) on the furrow surface in the shed that needs to be fertilized, and cover it with plastic film to maintain humidity; the stacking height is 40c...

Embodiment 2

[0038] Embodiment 2, change the disease-resistant bacteria in Example 1 into a phosphate-dissolving bacterium agent, and the phosphate-dissolving bacterium agent is prepared according to a conventional method by the preservation number of the China Agricultural Microorganism Strain Collection Management Center: Bacillus megaterium of ACCC11079. The number of viable bacteria in the phosphate solubilizing agent is ≥5×10 8 CFU / g.

[0039] The rest of the content is the same as in Example 1. After the secondary fermentation, a bio-organic fertilizer with functions such as phosphorus solubilization is obtained. As determined by the plate counting method, the number of effective viable bacteria in the bio-organic fertilizer is ≥1×10 8 CFU / g.

[0040] Comparative experiment 2, with Qingzi mud as the test soil, set up control (add 10g of fermentation residue per kilogram of soil) and bio-organic fertilizer (add 10g of the bio-organic fertilizer prepared in the above-mentioned embo...

Abstract

The invention discloses a method for directly composting CO2 fertilization fermentation residues into a bio-organic fertilizer in the field. The method includes regulating water content to 50%-70% in the fermentation residues serving as a fermentation substrate; mixing a microbial agent with the water to obtain agent mixed liquor, wherein the weight ratio of the microbial agent to the fermentation substrate is (4-6):1000, and the weight ratio of the water to the fermentation substrate is (10-20):1000; after the agent mixed liquor is mixed with the fermentation substrate, stacking on a bed surface needed to be fertilized in a greenhouse, and covering a plastic film to preserve moisture; and stacking with a height of 35-45cm for fermentation for 6-8 days under 15-40 DEG C to obtain the bio-organic fertilizer.

Description

technical field [0001] The invention relates to a method for directly composting bio-organic fertilizers in fields by using residues produced by fertilizing organic wastes to fertilize carbon dioxide. Background technique [0002] my country is the country with the fastest development of greenhouse cultivation in the world, and the current cultivation area is close to 3 million hectares. In order to pursue immediate economic benefits, it is very common to use super-high amounts of chemical fertilizers. The amount of nitrogen fertilizers used is several to dozens of times that of field crops. In addition, organic fertilizers are rarely used. Usually, soil degradation and damage will occur after 4-5 years of cultivation Problems such as continuous cropping obstacles have seriously restricted the sustainable development of the industry. Many research results have proved that the application of bio-organic fertilizer is a simple and effective method to solve soil degradation an...
