Description

Technical Field

[0001] The invention relates to the technical field of compound fertilizer preparation, and in particular to a compound microbial fertilizer and a preparation method thereof. Background Art

[0002] In recent years, the large-scale use of chemical fertilizers and pesticides has led to increasingly prominent soil problems, including acidification and compaction, reduced organic matter fertility, increasingly serious salinization and soil-borne diseases, and reduced yields and quality, resulting in a significant drop in profits for many growers. To increase yields, producers have increased their input of pesticides and fertilizers, leading to a vicious cycle.

[0003] Existing fertilizer technology basically uses nitrogen, phosphorus and potassium as the main raw materials of fertilizers, which leads to nutrient imbalance, soil acidification and compaction, many product diseases and pests, and reduced quality. Specifically:

[0004] 1) Compound fertilizers, which are other products on the market, have been sold in my country for decades and have made great contributions to Chinese agriculture. However, excessive use of compound fertilizers has caused soil problems and food health issues that are becoming increasingly prominent, and the government is paying more and more attention to them.

[0005] 2) Microbial fertilizer, which is made by fermenting organic matter (cow, sheep, chicken manure, straw, soybean meal, etc.). Although it plays a certain role in improving the soil, it lacks fertility, is costly, and can damage the roots if not fermented well.

[0006] 3) Organic-inorganic compound fertilizers, although they alleviated the soil problem, have gradually cooled down in the market due to the single strain of bacteria and lack of obvious results. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a composite microbial fertilizer and a preparation method thereof.

[0008] In order to achieve the above object, the present invention adopts the following technical scheme: a composite microbial fertilizer, comprising microbial fertilizer, organic fertilizer, composite fertilizer and trace elements;

[0009] The microbial fertilizer is composed of one or a mixture of two or more of Bacillus subtilis, Bacillus amyloliquefaciens and Trichoderma harzianum.

[0010] Organic fertilizer is made from organic materials such as animal and plant residues or excrement, which are fermented and decomposed.

[0011] Compound fertilizer consists of nitrogen, phosphorus, potassium, organic fertilizer, mineral powder and whole egg powder.

[0012] Trace elements include iron, boron, zinc, copper, calcium, magnesium and other elements.

[0013] A method for preparing a composite microbial fertilizer comprises at least the following steps:

[0014] S1 weighs a certain amount of microbial fertilizer, organic fertilizer, compound fertilizer and trace elements and puts them into a container with a stirrer;

[0015] S2: Add the components of step S1 into a blender and mix well;

[0016] S3 extrudes and granulates the mixture stirred evenly in S-2.

[0017] Extrusion granulation steps:

[0018] S3-1 drying the fermented mixture under sunlight, crushing it and sieving it to obtain a powder;

[0019] S3-2 The powder obtained in S3-1 is passed through a granulator to generate granular composite microbial fertilizer.

[0020] Among them, microbial fertilizer accounts for 50% to 60% of the total weight, compound fertilizer accounts for 30% to 40% of the total weight, organic fertilizer accounts for 30% to 40% of the total weight, and trace elements account for 5% to 10% of the total weight.

[0021] Preferably, the nitrogen content in the compound fertilizer is 8% to 15%, the phosphorus content is 5% to 8%, the potassium content is 8% to 15%, the mineral powder content is 20% and the whole egg powder content is 2% to 3%.

[0022] Preferably, the mesh size of the sieve is controlled at 5 to 10.

[0023] Preferably, the speed of the stirrer is 200 r / min.

[0024] The present invention has the following beneficial effects:

[0025] 1. Through the composite flora of microbial fertilizer, the flora environment of the soil is improved, and the reproduction of harmful bacteria is controlled through the dominant position of beneficial bacteria, so that soil-borne diseases are reduced. Beneficial bacteria greatly improve the efficiency of nitrogen, phosphorus and potassium through decomposition function, and the fertilizer efficiency is increased from 30% to 60%, thereby reducing the use of chemical fertilizers and improving economic benefits.

[0026] 2. Mineral powder is a special multi-element mineral composition, which has the functions of comprehensively supplementing various nutrients for plants, promoting rooting, overcoming repeated cropping and improving resistance.

[0027] 3. The combined use of organic fertilizer and compound fertilizer can increase soil organic matter and amino acids, which plays an important role in improving the taste and quality of crops. DETAILED DESCRIPTION
