Problems solved by technology

[0010] A large amount of urea is added to the current formula of humic acid compound fertilizer, which makes the organic matter in the soil decrease gradually, and the basic substances such as calcium and magnesium are deficient, so that the soil is acidified, the soil has no aggregate structure, and the conditions of water, fertilizer, gas and heat in the soil cannot be coordinated. , and high-concentration urea produces high-concentration ammonia poisoning in the process of hydrolysis, causing dangers such as yellowing of leaves and chlorosis symptoms of plants. At the same time, in the existing compound microbial fertilizers, the relationship between bacteria and bacteria They cannot interact and coordinate with each other, and they are antagonistic to each other. There are also microorganisms that are easily inactivated under high osmotic pressure after being mixed with high-c

Embodiment 1

[0051] Embodiment one: the production of granular humic acid biological compound fertilizer

[0052] Granular humic acid bio-composite fertilizer The method for producing granular humic acid bio-composite fertilizer using the following microbial compound bacteria is as follows:

[0053] 1. Preparation of activated humic acid:

[0054] The weathered coal with a humic acid content of 50-75% (dry basis) (water content between 25-37%) is evenly sprayed with 15-30% NaOH solution per ton before stacking, and the natural drying reaction, 7 The effect is better for more than 15 days, and then crushed through 40 mesh, 60 mesh is better, and the weathered coal powder is sieved; dissolve the weathered coal with water (tap water can be used) with 60-100% weathered coal weight 12-20% NH by weight 4 HCO 3 and weathered coal weight 11-19% K 2 CO 3 or 15-26% Na 2 CO 3 The prepared solution and the weathered coal powder are stirred evenly in a mixer, and then the temperature is raised t...

Embodiment 2

[0064] Embodiment two: the preparation of active humic acid raw material

[0065] Humic acid content is 50-75% (dry basis) weathered coal pulverized through 60 mesh effect is better, weathered coal powder is sieved; with weathered coal weight 60-100% water (using tap water can be used) to dissolve the weathered coal weight 12-20% ammonium bicarbonate and weathered coal weight 11-19% potassium chloride or 15-26% potassium nitrate to make a solution and weathered coal powder in a mixer and stir evenly, then heat up to 35 ° C under stirring -75°C insulation reaction for 5-10 hours is better), then dry below 100°C (in a desiccator) (storage and application effect are best when the water content is lower than 24%), and obtain potassium ammonium humate. Active weathered coal.

[0066] The particle size of the weathered coal is above 60 mesh, and the content of humic acid is 50%; the activator is NaOH, KOH, NaOH 2 CO 3 、K 2 CO 3 , NH 4 HCO 3 and / or NH 4 The catalytic oxidant ...

Embodiment 3

[0067] Embodiment 3: Granular humic acid biological compound fertilizer prevents and treats cotton fusarium wilt

[0068] By applying granular humic acid biological compound fertilizer, it can effectively prevent and control plant diseases and insect pests, treat yellow leaf disease caused by iron deficiency, promote the transportation of fertilizer in plants, and make the absorption of fertilizer more fully. According to Wang Shuqi of the Henan Institute of Chemistry, Shandong Agricultural College experimented with a new type of granular humic acid biological compound fertilizer for root irrigation, seed dressing, and spraying. It has no significant effect on the control of cotton yellow and yellow disease, and 500ml / mu (2000 times) is used for root irrigation. The control effect reaches 60-90%, the control effect reaches 43-75% with 25-150g / mu FA seed dressing, and the control effect reaches 23-27% with 1500 times application, and the root irrigation is the best.

Abstract

The invention discloses a particle-typed biological composite fertilizer and preparing method of humic acid, which is characterized by the following: adopting low-temperature graining and drying without breaking germ; dispensing solid particle typed fertilizer of humic acid, biological bacterial fertilizer and middle and trace element with weight rate at 2: (0. 1-0. 2): (0. 05-0. 1) through effective compatibility of microbe composite germ and humic acid and relative element; solving the coordinate action of each bacteria in the composite microbe fertilizer without mutual antagonism; making the bacteria display heat-proof property; blending the microbe and fitful quantity of azophoska fertilizer to act; fitting for increasing production and effectiveness in the agricultural domain.

Description

technical field [0001] The invention relates to the field of a humic acid microbial compound fertilizer, in particular to a granular humic acid biological compound fertilizer and a manufacturing method thereof. Background technique [0002] Humic acid is the remains of animals and plants, mainly the remains of plants. It is a kind of macromolecular organic weak acid mixture accumulated after the decomposition and transformation of microorganisms, as well as a series of changes in geochemistry and physics. Humic acid widely exists in soil, peat, lignite, weathered coal, oceans, lakes and swamps, and natural water also contains a small amount of humic acid. The total amount of humic acid contained in the soil is the largest, but the average content is less than 1%; the total amount contained in brackish water is also a lot, but the concentration is lower, and it is impossible to develop it as a resource. Among them, the most promising humic acid resources to be developed and ...
