Abstract
The present invention relates to a production process for extracting humus, which comprises the following steps that pulverized brown coal, a heated liquid reaction medium-water and one or a plurality of organic chelates are mixed with each other for a reaction, and sodium hydroxide or potassium hydroxide and hydrogen peroxide are added to reaction products; then, a pH value is regulated, and obtained liquid is dried so as to obtain the humus. Detail processes are disclosed in the specification. The production process has the advantages that the humus is prepared by extracting reaction products of organic chelation reaction substances and brown coal at normal pressure, and the humus can obviously promote the growth and development of plants; the humus can not be degraded and can not fail after the humus is stored for a long time, and the humus is widely suitable for different ecological environments and different crops; the content of humus extracted from brown coal is about 75% of the weight of the brown coal, the extracted humus contains humic acid, fulvic acid, humic acid and humin, and all the ingredients form soil stabilization humus. The production process is a current process which can reserve all effective humus in extract, and the humus is directly used as organic fertilizer in agricultural production.
Description
Technical field
The present invention relates to the extraction process of agricultural organic fertilizer, specifically, relate to by chemical reaction from brown coal and leonardite, extract the rotten technology of matter class material of planting as organic fertilizer.
Background technology
Rotten height of planting matter content is the important symbol of soil fertility in the soil.Its main component is a humic acids.Corruption is planted matter and is divided into humic acids, xanthohumic acid, humic acid and four parts of humin, in each composition, has hundreds of organism all to be considered to activity (effectively) composition in the soil organism.Soil humus can directly be regulated water, fertilizer, gas, the thermal process of soil, supplies with nutrition and energy that microorganism growth is grown, and simultaneously, the switched-media that matter is the nutritive ingredient in the soil is planted in corruption, and nutrient is more effectively absorbed by root system of plant.The composition that contains plant growth hormones in the matter is planted in corruption in addition, and plant-growth is had hormesis.
Brown coal and leonardite are acknowledged as the main source of diversified humate and humic acids, and contain each metal ion species, as sodium, potassium, copper, magnesium, zinc etc.Existing numerous at present technology of from brown coal, extracting humic acids, but when using the humic acids that is extracted, the whole growth result performance of plant is very unstable, and different plants is also very unstable and consistent to the reaction of these extracts.More there is the extract components of some technologies single, less stable, product easily decomposes, thereby influences its result of use.After humic acids stores for some time,, and effect is significantly descended usually because of the degraded of product effective constituent.Therefore, the humic acids that uses current existing technology to extract exists the inconsistent and fugitive problem of plant beneficial effect.At present, plant the Technology of matter, do not appear in the newspapers and application about the corruption of from brown coal, extracting efficient stable.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, and provide easy, an effective corruption of from brown coal, extracting efficient stable of technology to plant the Technology of matter.
Purpose of the present invention can realize by following measure: technological process is as follows, and the brown coal of pulverizing and the liquid reaction medium water and the organic sequestering agent mixing that are heated to 80-100 ℃ are reacted; Described organic sequestering agent is meant that any one or gluconic acid and the EDTA among gluconic acid, tartrate, tartronic acid, pentanedioic acid and the EDTA mixes organic sequestering agent according to what 2.5: 1 ratio formed, and the part by weight scope of brown coal and above-mentioned intercalating agent respectively is 1: 0.5-0.8,1: 0.6-0.8,1: 0.7-0.9,1: 1.0-1.2,1: 0.15-0.45,1: 0.35; The part by weight scope of brown coal and water is 1: 5-10, reaction times 30-60 minute; Add sodium hydroxide or potassium hydroxide, the part by weight scope of brown coal and sodium hydroxide or potassium hydroxide is 1: 0.10-0.20, reaction times 240-300 minute; Then, add hydrogen peroxide, the weight ratio of brown coal and hydrogen peroxide is 1: 0.02-0.05, reaction times 120-180 minute; The potential of hydrogen of the liquid product that adjusting extracts is regulated time 10-30 minute, and after adding alkaline matter, pH value remains in 12 to 13 scopes, and through precipitation, liquid is required product, institute's extracting liq make according to a conventional method dried after, promptly obtain corruption and plant matter.Like this, can keep and improve the stability that matter is planted in the corruption of being extracted.
The present invention has following advantage compared to existing technology, and technology of the present invention is to utilize organic chelated reactant and brown coal reaction, extracts the corruption of multiple stability and high efficiency and plants matter (comprising humic acids).Invention is carried out under normal pressure, the input of minimizing equipment and production difficulty, matter is planted in the corruption of being extracted, g and D to plant has obvious facilitation, and can not degrade and lost efficacy because of the storage of long period, and, can extensively adapt to different ecotopes and Different Crop, matter is planted in the corruption that extracts, and is about about 75% of brown coal amount.Extract not only contains humic acids, contain xanthohumic acid simultaneously, humic acid and humin, all these components are formed the soil stabilization corruption and are planted matter, technology of the present invention is at present unique by organic chelated and soda acid allotment, reaches to keep all the technological process that matter is planted in effectively corruption in extract.
