Preparation method and application of biological organic-inorganic liquid fertilizer

Abstract

The invention relates to a preparation method and application of a biological organic-inorganic liquid fertilizer. The biological organic-inorganic liquid fertilizer mainly comprises the following components: a beneficial bacterium with the content of 0.5 to 2 hundred millions per milliliter, nitrogen phosphorus and potassium with the content of 150g / L to 350g / L, organic carbon with the content of 150g / L to 300g / L, and a medium trace element with the content of 1g / L to 20g / L. The preparation method of the biological organic-inorganic liquid fertilizer comprises the following steps of first, carrying out fermentation cultivation on a beneficial microorganism solution, so that the content of an effective bacterium in the beneficial microorganism solution is above 100 hundred millions per milliliter, adding a microbial inoculum vigor-sustaining agent into a bacterium solution, treating the bacterium solution for 2 hours, then adsorbing the bacterium solution which is well treated by using a carrier, and adding the bacterium solution of which the adsorption is completed into the organic-inorganic liquid fertilizer, wherein the organic-inorganic liquid fertilizer needs to be subjected to a reaction in advance, so that inorganic nutrients in the organic-inorganic liquid fertilizer are subjected to an organic reaction, so as to reduce the harm of a high salt to a live bacterium.

Description

technical field [0001] The present invention relates to a preparation method and application of a biological organic-inorganic liquid fertilizer, in particular to the survival of biological bacteria in a biological organic-inorganic liquid fertilizer under high salt and high osmotic pressure and the preparation method of the liquid fertilizer and its application. application. technical background [0002] There are several major problems in the current production and use of fertilizers. First, the utilization rate of fertilizers is low, with an average of about 30% in my country. Second, the use of chemical fertilizers and pesticides for many years has caused serious soil damage, low organic matter content, insufficient microbial populations, and more and more soil-borne diseases. The more serious it is; the third is that the research and development of fertilizers cannot keep up with the pace of modern agricultural development. Large-scale and modern agriculture emphasizes ...

Problems solved by technology

At present, some domestic bio-organic and inorganic fertilizers are basically solid. They use ordinary organic fertilizers as carriers and add biological bacteria and inorganic nutrients. Although they can solve some problems, they have major defects: first, solid Fertilizer can only be used as base fertilizer, and cannot be used as top dressing during crop growth; second, it cannot meet the requirements of current agricultural modernization, and cannot adapt to modern agricultural facilities such as drip irrigation and sprinkler irrigation; third, solid fertilizer cannot achieve beneficial bacteria, organic A reasonable ratio between carbon fertilizer and inorganic nutrients to meet the needs of crops

[0005] This product mainly solves two major problems in fertilizer production. One is to add beneficial microorganisms to high-content (NPK) liquid fertilizers and still maintain their activity; than the problem
