preparation example Construction

[0030] Such as figure 1 Shown, a kind of highly active straw organic-inorganic fertilizer preparation method of the present invention comprises the following steps:

[0031] (1) Pretreatment of straw (standby)

[0032] A. Crush: Crush the straw to 40-50 mesh.

[0033] B. Alkali-ammonia compound treatment: make 20% alkali-ammonia solution from urea and calcium hydroxide each accounting for 4-6% of the mass percentage of straw, heat it to 70-80°C, mix it evenly, and spray wine after step A Put it on the treated straw, seal it, store it for 3-4 days, take it out and dry it, and collect the remaining alkaline ammonia solution for later use.

[0034] C. Acidification treatment: make 20% dilute sulfuric acid solution with concentrated sulfuric acid (concentration ≥ 93%) accounting for 4-6% of the straw mass percentage, spray wine evenly on the straw treated by step B, and store for 1-2 days Take it out and dry it, and collect the remaining dilute sulfuric acid solution for later ...

Embodiment 1

[0054] Prepare a product with 16% organic matter content and 30% nitrogen, phosphorus, and potassium nutrient content, taking the raw material consumption quota for 1 ton of product as an example:

[0055] Specific production process:

[0056] 1. Straw pretreatment:

[0057] (1) Crush 1 ton of wheat and rice straw to 50 mesh.

[0058] (2) Make 20% alkaline ammonia solution with 50 kg of urea and 50 kg of calcium hydroxide, heat it to 75°C, mix it evenly, spray wine on the crushed straw, seal it, store it for 3 days, take it out and dry it. The alkaline ammonia solution is collected into the storage tank.

[0059] (3) Make 50 kg of concentrated sulfuric acid (concentration 95%) into a dilute sulfuric acid solution with a concentration of 20%, spray wine evenly on the straw treated in the previous step, store it for 2 days, take it out and dry it, and collect the remaining dilute sulfuric acid solution into a storage tank middle.

[0060] (4) Dissolve 3.5 kg of crude fiber q...

Embodiment 2

[0066] Prepare a product with 18% organic matter content and 32% nitrogen, phosphorus, and potassium nutrient content, taking the raw material consumption quota for 1 ton of product as an example:

[0067] Specific production process:

[0068] 1. Straw pretreatment:

[0069] (1) Crush 1 ton of corn and rice straw to 50 mesh.

[0070] (2) 55 kg of urea and 55 kg of calcium hydroxide are made into 20% alkali ammonia solution, heated to 80°C, mixed evenly, sprayed wine on the crushed straw, sealed, stored for 2 days, taken out to dry, and the remaining The alkaline ammonia solution is collected into the storage tank.

[0071] (3) Make 55 kg of concentrated sulfuric acid (concentration 93%) into a dilute sulfuric acid solution with a concentration of 20%, evenly spray wine on the straw treated in the previous step, store it for 2 days, take it out and dry it, and collect the remaining dilute sulfuric acid solution into a storage tank middle.

Abstract

The invention discloses high-activity straw organic-inorganic fertilizer and a preparation method thereof. Straws, high-activity humic acid, inorganic fertilizer and kaolin are added into the materials. The preparation method comprises the following steps: treating the straws by various methods of alkali-ammonia composite treatment, acidification treatment and biological treatment; collecting and utilizing the residual solution; performing material pelleting by taking a calcium sulfate solution and a urea sulfate solution which are generated through the reaction of an alkali-ammonia solution and a dilute sulfuric acid solution as liquid phase required by material pelleting and taking urea sulfate and the kaolin with special viscosity as adhesive required by granulation; and preparing the granular products, wherein no waste water and no waste liquid are discharged in the production, so the environment-protecting problem that the solution is difficult to treat in the existing chemical treatment technology is solved. The product synthesizes the characteristics of organic fertilizer and inorganic fertilizer, and has the effects of improving and activating soil, improving reproduction activity of microorganism in the soil, improving the granular structure of the soil, improving the quality of crops and increasing the yield of the crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a highly active straw organic-inorganic fertilizer and a preparation method. Background technique [0002] my country is a large agricultural country, with an annual output of more than 800 million tons of agricultural straw. The resources are huge and cover a wide area, but they have not been fully utilized. At present, there are still a large number of straws that are piled up or burned casually, and the organic matter, nitrogen, phosphorus, potassium, and trace elements such as magnesium, calcium, and sulfur rich in straw are lost in large quantities, which leads to serious air pollution and wastes valuable resources. H. Straw lignocellulose and hemicellulose are high in content and difficult to decompose, resulting in slow decomposition and low degradation rate of straw during saccharification or fermentation. Therefore, lignocellulose and hemicellulose need to be pretre...
