Embodiment 1

[0057] A preparation method of compound microbial fertilizer, the steps are as follows:

[0058] (1) Inoculate Bacillus jelly-like bacillus CICC23640, Bacillus megaterium CICC21694, Bacillus cereus CICC21687 and Bacillus thuringiensis CICC20565 in liquid seed medium respectively, culture in liquid at 30°C for 24 hours, and then inoculum at 10wt% Inoculate in liquid fermentation medium, culture at 30°C for 3 days, absorb with peat, dry at 45°C, pulverize, and sieve;

[0059] 6×10 live bacteria containing jelly-like bacillus CICC23640 were prepared respectively 9 Bacteria agent A per g, containing 5×10 live bacteria of Bacillus megaterium CICC21694 9 Bacteria B, Bacillus cereus CICC21687 viable count 6×10 per g 9 Bacteria C and Bacillus thuringiensis CICC20565 live bacteria count 5×10 per g 9 Individual / g of bacterial agent D;

[0060] The liquid seed medium in the step (1) is prepared by mixing and sterilizing the following raw materials:

[0061] Yeast extract 5g, peptone...

Embodiment 2

[0083] The preparation method as described in Example 1, the difference is that in step (5), the prepared bacterial agent A, bacterial agent B, bacterial agent C, bacterial agent D, bacterial agent E, bacterial agent F and bacterial agent Agent G was mixed in a weight ratio of 1:1:2:3:1:1:1 to prepare a composite microbial agent with a total bacterial count of 4.5×10 9 pcs / g.

Embodiment 3

[0085] 340kg of yeast fermentation powder residue, 200kg of organic fertilizer, 200kg of urea, K 2 SO 4 100kg, NH 4 h 2 PO 4 110kg, 50kg of clay are mixed with 15kg of the compound microbial inoculum prepared in Example 2, and the mixed compound mixture is transported to a granulator by a conveyor for granulation, and dried at low temperature to obtain a compound microbial fertilizer.

[0086] The organic matter content of the obtained fertilizer is 25 wt%, the total content of N, P and K is greater than 25 wt%, and the number of effective viable bacteria is greater than 60 million / g.

Abstract

The invention relates to a compound microbial fertilizer and a preparation method thereof. The compound microbial fertilizer is prepared by mixing the following raw materials: yeast fermentation powder residues, an organic fertilizer, urea, K2SO4, NH4H2PO4, clay and a compound microbial agent; and the compound microbial agent is formed by fermentation of bacillus mucilaginosus, bacillus megaterium, bacillus cereus, bacillus thuringiensis, azotobacter chroococcum, pichia farinose and streptomyces microflavus. The compound microbial fertilizer disclosed by the invention has a variety of microbes with the effects of nitrogen fixation, phosphorus dissolution and potassium dissolution, can increase the nitrogen content in soil, improves the utilization rate of the chemical fertilizer, and is favorable for improving the structure of the soil and improving the yield and quality of crops; and simultaneously, the microbes in the fertilizer can produce a variety of metabolites, and the metabolites can effectively resist diseases and insect pests.

Description

technical field [0001] The invention relates to a compound microbial fertilizer and a preparation method thereof, belonging to the technical field of microbial fertilizers. technical background [0002] my country is a large agricultural country, and fertilizer plays a very important role in my country's grain production. However, there are some unreasonable factors in the use of fertilizers, which reduce soil fertility and fertilizer utilization rate; soil structure is destroyed, resulting in soil compaction, water and fertilizer retention capacity decline, seriously affecting the yield and quality of crops. [0003] With the development of my country's agriculture, the discharge of orange stalks, manure and other wastes has also increased. These wastes are not well utilized, and the phenomenon of straw burning continues unabated. A large number of livestock and poultry manures are discarded. Become a serious source of pollution, to solve the way out of these organic wastes...
