A kind of double stage fermentation liquid fertilizer and preparation method thereof

Abstract

The invention discloses a double-stage fermented liquid fertilizer and a preparation method thereof, which comprises the steps of: cleaning, kneading and crushing fresh green plants, spraying mixed and awakened anaerobic composite bacterial liquid, compressing into blocks, and carrying out the first-stage fermentation Until the fiber of the material is softened; the material after the first stage of fermentation is subjected to high-consistency grinding and medium-consistency grinding and refining processes, and the straw pulp is washed out of the multi-fiber material, and the washing liquid and the low-fiber slurry are sent to the fermentation after the air is removed. Fermentation in the tank, jet agitation, after fermentation, the material is discharged for pressure filtration to form liquid fertilizer and solid fertilizer. The present invention can use bright green plants as raw materials for industrialized production of liquid fertilizers and solid fertilizers, as well as making grass pulp, which has strong environmental protection; in addition, green liquid fertilizers contain various plant natural enzymes and a large amount of small molecular organic matter, microorganisms and their metabolites , Since each plant contains thousands of natural enzymes, it is possible to ensure that the plant's natural enzymes are not lost during the fertilizer making process, thereby promoting the growth of crops, which is environmentally friendly and natural, and has high safety.

Description

technical field [0001] The invention relates to a double-stage fermentation liquid fertilizer and a preparation method thereof. Background technique [0002] Plant enzymes express the internal life functions of plants. Modern technology uses chemical methods to imitate plant enzymes, and amino acids are chelated with zinc, silicon, boron, potassium, iron, calcium, etc. to make plant cell revitalizers, growth promoters, rooting agents, Bacteriostatic factor, adding trace elements at the same time to make a chlorophyll synthesis agent, which can effectively prevent yellow leaves, small leaves, and rolled leaves, make diseased leaves become healthy leaves, prevent flower and fruit drop, and promote crops to go on the market in advance. The above-mentioned synthetic enzyme products belong to plants growth hormone category. Another fertilizer method in agriculture is to mix dual enzymes into urea, compound fertilizer, organic fertilizer, or make water-soluble fertilizer and so o...

Problems solved by technology

Plant natural enzymes have coexisted with humans for a long time, and their natural enzymes have complex structures, which are easy to decompose and metabolize;

[0007] Second, the number of synthetic enzymes is limited. Although they can promote the rapid growth and absorption of crops, their functions and nutrition are not comprehensive. Fruits and vegetables grow quickly but lose their natural flavor. This is a common phenomenon.

[0008] Third, synthetic enzymes are absorbed by crops and transferred to the human body. These chelate compounds of amino acids and metals have the catalytic properties of enzymes. If there is abnormal catalysis and metabolism in the body, its safety is worrying

[0009] Chinese patent CN103140456 discloses a method and a pulverizer for fresh grass fermented liquid fertilizer, which can only pulverize the fresh grass of the lawn in the golf course into fine particles before fermenting, because it needs to be crushed into fine particles with a diameter less than or equal to 0.1mm , the fresh grass raw materials that can be used are limited, and this process cannot be extended to some vegetation raw materials with long diameters in nature, and it does not involve the comprehensive development of multi-fiber green grass pulp and the preservation method of seasonal forage ; moreover, its equipment can only be used to crush the short grass of the golf course and the efficiency is not high. In the environment of rolling ball impact, ball mill impact and impact heating will inactivate the fermentation microorganisms and natural enzymes in the material, which will damage the natural activity of liquid fertilizer, and the ball mill movement and fermentation gas will increase the internal pressure of the ball mill, and there is a risk of bursting, so Its technology cannot be popularized for industrialized utilization

[0010] The fermentation of Chinese patent CN108863675 belongs to the fermentation method of ordinary organic fertilizer, which belongs to solid high-temperature fermentation. Due to the high temperature in the whole fermentation process, it can inactivate the natural enzymes in the plants, and it cannot make the final organic fertilizer contain rich types, Natural enzymes with high activity; and a large amount of gas is produced during the entire solid fermentation process, which does not meet environmental protection requirements. At the same time, the stretchability of the organic chain end groups of solid fermentation is different from that of liquid fermentation, the fertilizer efficiency is different, and the microbial efficiency is worse than liquid fermentation; , because it uses animal feces to participate in fermentation, so that the anorectal bacteria in the animal body also participate in the fermentation, resulting in unhygienic fertilizers, and there is a hidden danger of anorectal bacteria polluting farmland and even water quality
