Organic liquid fertilizer and preparation method thereof

Abstract

The invention discloses an organic liquid fertilizer and a preparation method thereof. The invention aims to solve the technical problems of environment-friendly and pollution-free components, rich selenium, favorable slow-release effect and long fertilizer efficiency. The preparation method comprises the following steps: (1) adding deionized water, fish meal and sodium selenite into a fermentation tank according to parts by weight, and stirring by introducing oxygen; (2) fermenting pulverized fresh algae and plant ash in a fermentation cask; (3) injecting deionized water into a conical flask, injecting microbes, adding mesoporous SiO2 into the conical flask, putting the conical flask filled with the microbes and mesoporous SiO2 on a constant-temperature culture shaking table, and culturing; (4) pouring the mixed solution obtained in the step (2) and step (3) into the solution in the step (1), and fermenting the obtained mixture; and (5) filtering the fermentation mixture in the step (4) to obtain the organic liquid fertilizer.

Description

technical field [0001] The invention relates to an organic liquid fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is a kind of substance that provides one or more essential mineral elements for plants, improves soil properties, and improves soil fertility. It is one of the material basis of agricultural production. With the continuous development of social life, people's demand for food production is increasing, resulting in the use of chemical fertilizers in agricultural production to achieve a significant increase in production and income. It is impossible for all kinds and forms of chemical fertilizers applied in farmland to be absorbed and utilized by plants. The utilization rate of nitrogen fertilizer is 30-60%, the utilization rate of phosphorus fertilizer is 2-25%, and the utilization rate of potassium fertilizer is 30-60%. Long-term and large-scale application of chemical fertilizers leads to a series of environmental pollution....

AI Technical Summary

Problems solved by technology

In agricultural production, organic fertilizers or chemical fertilizers are mixed with water and sprayed directly on the leaves or roots of plants, so that crops can absorb them quickly and reduce the impact of fertilizers on the soil; however, due to the limited adhesion of liquid fertilizers on plant leaves, As a result, the leaf surface has not fully absorbed the ingredients in the fertilizer and then slips from the leaf surface, which affects the use effect of the foliage fertilizer; with the development of science and social progress, people have higher and higher requirements for food, and the selenium content in food Low, difficult to meet people's needs
