Preparation method of active ferment liquid fertilizer

Abstract

The invention provides a preparation method of an active ferment liquid fertilizer. The method comprises the following steps: 1, crushing 30-50kg of Artemisia argyi, Artemisia stelleriana, Achnatherum splendens, Divaricate Saposhnikovia Root or Syzygium aromaticum to 40-60 mesh particles, and carrying out supercritical carbon dioxide extraction under an extraction pressure of 20-30Mpa at an extraction temperature of 25-30DEG C for 80-100min with methanol or chloroform as an entrainer to obtain a plant extract product for later use; 2, crushing 20-40kg of zeolite, Chinese medical stone, vermiculite or calcium carbide to 100-350[mu]m powder, adding the powder into a high pressure container, adding 100-120kg of water, heating to 250-350DEG C, maintaining the pressure in a range of 25-35Mpa for 20-30min, and cooling to room temperature; and 3, adding the plant extract product obtained in step 1, 80kg of an ore extract liquid obtained in step 2, 40-50kg of brown sugar and 30-35kg of composite ferment to a container provided with 1200-1500kg of clear water, and carrying out normal temperature fermentation for 25-30d.

Description

technical field [0001] The invention relates to a preparation method of active enzyme liquid fertilizer, belonging to the technical field of liquid fertilizer preparation methods. Background technique [0002] At present, there are few types of pure biological liquid fertilizers in foreign countries. Among the existing biological liquid fertilizer preparations, most of them are crop growth regulators, such as hormones, auxins, and microbial bacterial agents. The biological liquid fertilizers developed by South Korea, Japan and other countries have not been popularized and applied on a large scale due to their shortcomings such as strict extraction and purification process requirements, high production costs, expensive products, and single functions (only acting as hormones). Similarly, although there are many types of biological liquid fertilizers in China, there are still some deficiencies in the functions of bacterial agents, production processes, cost prices, application ...
