Silicic acid-containing microbe organic fertilizer and preparation method thereof

Abstract

The invention provides a microbial organic fertilizer containing silicic acid. The raw materials of the organic fertilizer include potassium fulvate, peat, palmitic acid, amino acids, chicken bones, silicic acid, organic nitrogen, phellandrene, alkyd resin powder, Water hyacinth plant, red jade soil, psyllium seed husk powder, pseudomonas hibiscus hibiscus, halococcus cod; the invention also provides a preparation method of the above fertilizer. In the fertilizer prepared by the present invention, the number of effective viable bacteria is 64-680 million cfu / g, the total nitrogen content is 3.3-3.5wt%, the total phosphorus content is 3.0-3.2wt%, the total potassium content is 2.2-2.3wt%, and the organic matter (on a dry basis) content is 47.2-47.5wt%, water content 21.0-21.3wt%, pH is 5.6-5.7; the fertilizer prepared by the present invention has the effect of improving saline-alkali soil, reducing sulfate content and soil pH in soil to increase the organic matter content in the soil.

Description

technical field [0001] The invention relates to a microbial organic fertilizer containing silicic acid and a preparation method thereof, belonging to the technical field of biological organic fertilizers. Background technique [0002] The beneficial microorganisms in the microbial organic fertilizer enter the soil and form a symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic role in the group. The beneficial bacteria grow and reproduce A large number of metabolites are produced during the process, which promotes the decomposition and transformation of organic matter, and can directly or indirectly provide crops with a variety of nutrients and stimulating substances to promote and regulate crop growth. [0003] Increase beneficial bacteria and soil microorganisms and populations. At the same time, the dominant ben...

AI Technical Summary

Problems solved by technology

[0008] (2) For the improvement of sulfate-type saline-alkali land, the improvement effect is single, and it cannot effectively reduce the sulfate content in the soil at the same time; reduce the soil pH, reduce the total salt content of the soil, increase the organic matter content in the soil, increase the total nitrogen content in the soil, 0-20cm soil available phosphorus content, available potassium content, improve soil water permeability, improve soil water retention capacity;

[0009] (3) For millet planting in saline-alkali land, the survival rate of millet is low, the yield is low, the plant is short, the ear length is less than 20cm, the weight of a single ear is less than 20g, the ear-grain weight and thousand-grain weight are small, and the yield of grain and rice is low;

[0011] (5) It is used for millet planting in saline-alkali land, and has no control effect on millet pests at the seedling stage
