Problems solved by technology

However, after long-term use of chemical fertilizers and pesticides, people have discovered a problem: the physical and chemical properties of the soil have deteriorated sharply, soil compaction, salinization, nutrient imbalance, and soil fertility have declined. To ensure production, the only way to increase the use of chemical fertilizers year by year will not only greatly increase production costs, but also worsen the deterioration of the soil environment, falling into a vicious circle
With the development of more than ten years, the quality of bio-organic fertilizers has been improved to a certain extent, but the products currently on the market still have many shortcomings to a large extent, mainly in the following aspects: 1. Production Backward technology; 2. High production cost; 3. Unstable product quality, etc.
[0006] The main reasons for these shortcomings are: the current production of bio-organic fertilizers mainly adopts the method of separate cultivation of bacteria and step-by-step fermentation of organic fertilizers. The quality of the products is very unstable, and there is a considerable degree of straw resistance between the various strains in the finished product and between the environment. The microbial content of good products can be controlled at a relatively high level in a short period of time, but once the field is released or the environment changes, the semi-dormant strains will be activated and produce straw resistance to each other, plus the impact on the environment If it is not adapted, the number of microorganisms will drop sharply, so the effect on the sustainability of fertilizer efficiency and the restoration of the soil environment is limited
In addition, in the step-by-step fermentation process of many bio-organic fertilizers, anaerobic and aerobic fermentations are often carried out separately. The metabolites of the two fermentation processes cannot be well utilized by the microorganisms participating in the fermentation process of the other party. The composition content of the final product cannot reach a good level, so most of them are formulated by adding chemical fertilizers after fermentation to increase fertility or adding other chemicals to increase the content of trace elements in the product.
Strictly speaking, organic fertilizers produced in these ways can only be regarded as compound fertilizers, not biological organic fertilizers.

Embodiment 1

[0070] (1) Expansion and cultivation of microbial strains:

[0071] Bacillus subtilis, Bacillus stearothermophilus, and Nocardia tan were respectively adopted in the following component culture medium, cultivated on a slant, and in 1000ml of water, the content of each component was as follows:

[0072] 5 grams of yeast extract, 5 grams of peptone, 1 ml of Tween-80, 50 grams of sugar, 0.5 grams of NaCl, K 2 HPO 4 0.5 g, MgCl 2 0.5 g, CaCO 3 0.5 grams, 18 grams of agar, pH 7.3;

[0073] Streptomyces albicans adopts the following component medium, cultivated on a slant, and in 1000ml of water, the content of each component is as follows:

[0074] KNO 3 1 g, MgSO 4 0.5 g, NaCl 0.5 g, K 2 HPO 4 0.5 g, FeSO 4 0.01 grams, 20 grams of soluble starch, 18 grams of agar, the pH value is 7.3;

[0075] Culture time and temperature:

[0076] Cultivate Bacillus subtilis and Nocardia brownus at 30°C for 24 hours; Streptomyces albicans at 30°C for 48 hours; Bacillus stea...

Embodiment 2

[0100] Others are all the same as in Example 1, the difference is:

[0101] (1) The organic wastes used are:

[0102] 70 kg of fresh pig manure, 5 kg of soybean meal and 5 kg of peanut cake are mixed with 20 kg of straw powder;

[0103] (2) Inoculate the carrier of the adsorbed bacteria in the preparation method step (4) according to 0.8‰ of the total weight of the organic waste to be treated;

[0104] Test result is identical with embodiment 1.

Embodiment 3

[0106] From April to May in 2005, under the premise of the same price (the consumption is respectively: the product of this project-300 kg / mu, the contrast product-140 kg / mu), the product of the present invention and various fertilizer products The organic-inorganic compound fertilizer, which requires the highest total nutrient content except chemical fertilizers, has been applied in a comparative test on the planting of solanaceous vegetables, and the results are as follows:

[0107] 1. Effects on crop appearance and quantity (average):

[0108]

[0109]

[0110] 2. Preliminary production investigation and analysis (average): unit: kg

[0111]

[0112] The test shows that although the total nutrient content (≥300kg×6%) is not as high as the compound fertilizer (≥140kg×15%), the fertilizer effect is more significant because the nutrient structure contained in the product of this project is more easily absorbed by crops .

Abstract

This invention relates to a method to prepare a kind of bioorganic fertilizer and its application. The preparation method includes following steps: a) proliferation and cultivation of microorganism species; b) cultivation of microorganism species against stalk antibody; c) adsorption onto a carrier and drying into organic decomposers; d) preprocessing of organic waste; e) inoculation complex fermentation and f) continuous high-temperature fermentation and nontoxification. This invention has the advantages of advanced technique, low production cost, stable product quality and long fertility persistence and can be widely applied in the production of corns, vegetables, fruits and all kinds of economic crops. Besides, it is a green method makes considerable economic, social and environmental benefits.

Description

technical field [0001] The invention relates to a bio-organic fertilizer and a preparation method thereof, in particular to a method for simultaneously fermenting organic material decomposing agents mixed with organic waste materials by utilizing industrial, agricultural and domestic organic wastes through multi-bacteria. Background technique [0002] As a source of nutrients necessary for plant growth, fertilizer has always been one of the important factors affecting agricultural production. With the rapid increase of population, the shortcomings of poor fertility of traditional farmyard manure have emerged. In order to increase the fertility, the only way to increase the amount of fertilizer is to take it. [0003] Since the production of traditional farmyard manure is a natural fermentation method using compost, a large number of pathogenic bacteria and parasite eggs cannot be effectively killed. After increasing the dosage, the incidence of crop diseases and insect pests...
