Problems solved by technology

Humic acid is mentioned in a large number of patented technologies, and most of the patented technologies are made by mixing humic acid with conventional inorganic fertilizers. Although individual technologies have a fermentation process, they cannot provide many trace elements; and Only a few technologies activate humic acid in the process of fertilizer production, and most technologies do not consider the properties of activated humic acid

Embodiment 1

[0020] The present invention comprises the following steps:

[0021] (1) preparation of active humic acid

[0022] Take peat and lignite as humic acid raw materials, add humic acid raw materials to 3.0mol / L NaoH solution at a weight ratio of 1:3, raise the temperature to 43°C, stir and heat for 2-3 hours to make it fully react, and filter after the reaction is completed , collect the filtrate, then filter the remaining humic acid raw material and 3.0mol / L NaoH solution in a weight ratio of 1:3 and mix them, heat up again, stir and heat, filter, repeat three times, and combine the filtrates obtained by the three processes, The pH value of the filtrate is adjusted to 6.0-6.7 with inorganic acid to obtain active humic acid.

[0023] (2) Preparation of fermented substance

[0024] Take the active humic acid obtained in the previous step and add it to livestock and poultry manure, mix according to the mass ratio of livestock and poultry manure, active humic acid and starter at 91...

Embodiment 2

[0030] The present invention comprises the following steps:

[0031] (1) preparation of active humic acid

[0032] Take lignite and weathered coal as humic acid raw materials, then add humic acid raw materials to 3.0mol / L NaoH solution at a weight ratio of 1:4, heat up to 40-45°C, stir and heat for 2-3h, to make it fully react, After the reaction is completed, filter and collect the filtrate, then mix the remaining humic acid raw material and 3.0mol / L NaoH solution in a weight ratio of 1:4, heat up again, stir and heat, and filter, repeat three times, and combine the three processes The filtrate, the pH value of the filtrate is adjusted to 6.0 to 6.7 with inorganic acid, so as to obtain active humic acid;

[0033] (2) Preparation of fermented substance

[0034] Take the active humic acid obtained in the previous step and add it to livestock and poultry manure, and mix according to the mass ratio of livestock and poultry manure, active humic acid and starter (91-97): (5-1): (...

Abstract

The present invention provides a method for preparing a special vegetable organic fertilizer by using active humic acid fermentation. The method comprises: (1) preparing active humic acid; (2) preparing a fermentation substance, wherein the active humic acid obtained in the step (1) is taken and is added to livestock and poultry manure, mixing is performed according to a mass ratio of the livestock and poultry manure to the active humic acid to a fermentation agent of (91-97):(5-1):(4-2), and crushing, uniform stirring, screening and adding are performed to prepare the fermentation substance; (3) adding minerals, wherein mixing is performed according to a mass ratio of the fermentation substance to the minerals of (85-92):(15-8); and (4) preparing the special vegetable organic fertilizer through fermentation, wherein granulation, drying and cooling are performed after completing the fermentation so as to prepare the special vegetable organic fertilizer. According to the present invention, the active potassium humate prepared from the nature humic acid-containing raw material is completely utilized and is combined with the organic matter to prepare the special vegetable organic fertilizer, such that advantages of nature greening, environment purifying, and benefiting on beneficial cycle of ecological organic agriculture are provided.

Description

technical field [0001] The invention belongs to the field of organic fertilizer production, and in particular relates to a method for preparing special organic fertilizer for vegetables by fermenting active humic acid. Background technique [0002] Humic acid and its products have many uses in agriculture. It is combined with nitrogen, phosphorus, potassium and other elements to make humic acid fertilizers, which have the functions of increasing fertilizer efficiency, improving soil, stimulating crop growth, and improving the quality of agricultural products; nitro humic acid can be used as an acid regulator for rice seedlings; Magnesium acid, zinc humate, and urea iron humate have good effects in supplementing magnesium deficiency in soil, zinc deficiency in corn, and iron deficiency in fruit trees respectively; humic acid is mixed with pesticides such as webfefen and atrazine. Active humic acid is a humic acid with chemical reaction ability, which can undergo ion exchange...
