Method for preparing multielement organic fertilizer by spontaneous fermentation of active humic acid

Abstract

The invention relates to a method for preparing multielement organic fertilizer by spontaneous fermentation of active humic acid, which comprises the following steps of: (1) preparing active humic acid; (2) preparing a fermentation substrate; (3) preparing leaven; (4) adding mineral substances; and (5) preparing multielement organic fertilizer by fermenting. In the method of the invention, humic acid-containing natural raw materials and ferment active potassium humate extracted from industrial waste residues are utilized fully, can be applied directly as fertilizer to be, and also can be used to prepare high-quality microbial organic fertilizer and organic-inorganic compound fertilizer which needs to be applied to various crops together with other nutrients and organic matters. The method has the advantages of turning waste into wealth, utilizing comprehensively, greening nature, purifying the environment and contributing to the virtuous circle of ecological organic agriculture; and the multielement organic fertilizer prepared from active humic acid is favorable for improving soil, increasing soil fertility and improving crop quality. The method has simple equipment and is time-saving and labor-saving, and a process method is simple, convenient and feasible, and is favorable for the popularization and application of villages.

Description

technical field [0001] The invention relates to fertilizers, in particular to organic fertilizers, in particular to a method for preparing organic fertilizers through fermentation. Background technique [0002] As we all know, 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; the mixed use of humic acid, webfebfex, atrazine and other pesticides can improve the efficacy and inhibit Residual poison; sodium humate is effective in treating apple tree rot.

Problems solved by technology

Most of the above-mentioned patented technologies are made by mixing humic acid and conventional inorganic fertilizers. Although individual technologies have a fermentation process, they can not provide many trace elements; and only a few technologies activate humic acid during the production of fertilizers. Most technologies do not take into account the properties of activated humic acid
