Example Embodiment

[0021] Example 1:

[0022] A humic acid microbial embedded fertilizer, characterized in that it is made of the following parts by weight (Kg) of raw materials: oyster shell powder 25, 2mol / L hydrochloric acid solution 80, chicken feathers 40, rotten straw 35, urea 12, hydrogen carbonate Ammonium 22, soil microbial agent 10, lotus pond sludge 40, ammonium calcium phosphate 22, potassium chloride 12, microbial embedding agent 10 and appropriate amount of water;

[0023] The microbial embedding agent is composed of liquid a and liquid b in a ratio of 3:1. Liquid a is a mixture of sodium alginate 8 and polyvinyl alcohol 10 and added to 40-50 times its weight in water, heated at 70-80°C It is made by stirring and dissolving, keeping it at 28℃ for later use; liquid b is anhydrous calcium chloride 6, peat 4, limestone powder 15, linseed oil 10, acrylate 20, ethanol 15 and appropriate amount of water; the preparation method is in the reactor Dilute ethanol 6-8 times with water, then add a...

Abstract

The invention discloses a humic acid microbial embedded fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials: oyster shell powder, a hydrochloric acid solution (2 mol/L), chicken feather, rotten straw, urea, ammonium bicarbonate, a soil microbial inoculant, lotus pool mud, calcium bicarbonate, potassium chloride, a microbial embedding agent, and a proper amount of water. According to the preparation method, a modified embedding agent is used to embed microbes, the embedding agent reacts with the material that produce humic acid at first, the embedding agent is decomposed and adsorbed and can co-exist with the material, thus the vitality of microbes can be guaranteed, and the fertilizer has a higher biological value.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a humic acid microorganism-embedded fertilizer and a preparation method thereof. Background technique [0002] Microbial fertilizers can partially replace chemical fertilizers, reduce the loss and waste caused by their extensive use, and even cause soil salinization and environmental pollution. The common dosage forms of microbial fertilizers are either bacterial liquids received after fermentation, or made with peat as a carrier The two formulations are more convenient in preparation, but both have many disadvantages, such as after the bacterial agent is applied to the soil, the bacteria are directly exposed to the open state, which is easy to cause the death of the bacteria. Proliferate to a certain level within a certain period of time, which is not easy to achieve. The embedding method is one of the cell immobilization technologies developed in recent years. ...
