The non-drying agent is added in a blending manner during preparation of the bio-organic fertilizer, has strong water absorption capacity, can change free water in the fertilizer or other raw materials into crystal water, thereby playing a non-drying effect and being used as the fertilizer.
Description
Technical Field
The invention belongs to the technical field of fertilizers, and particularly relates to an organic fertilizer, a biofertilizer drying-free essence and a preparation method thereof.
Background
A large amount of biomass wastes are generated in agricultural production and rural life in China, and the resource treatment pressure is increasing day by day. The crop straws in China are large in quantity, various in types and wide in distribution. At present, the patterns of agricultural straw fertilization, feed transformation, base transformation, raw material transformation and fuel transformation multi-element utilization are basically formed.
In the traditional fertilizer granulation production, the finished product of the granulated fertilizer is finally obtained through the technological processes of granulation, screening, drying and the like, and the production process has the defects of high fixed asset investment, long production time, high cost and high energy consumption.
The biological organic fertilizer is a fertilizer which is compounded by microorganisms with specific functions and organic materials mainly prepared from animal and plant residues (such as livestock and poultry manure, crop straws and the like) through harmless treatment and decomposition. With continuous advocation and deepening of social energy conservation and environmental protection development concepts, if a drying-free granulation process can be realized in the granulation process of the granulated fertilizer, the energy consumption is saved to a great extent. The common preparation process of the granular bio-organic fertilizer utilizes a drying process to dry granules, and simultaneously increases the hardness of the granular fertilizer to be beneficial to later storage, but a large amount of energy is consumed in the drying process of the granular fertilizer.
Chinese patent CN 201810493132.0 discloses a preparation method of a drying-free fertilizer, which comprises the following steps: respectively melting the main material and the auxiliary material, and then mixing to obtain first slurry; the auxiliary material comprises a drying agent, and the drying agent comprises nano calcium carbonate and modified magnesium oxide; feeding the first slurry into a mixing tank for fully mixing to obtain second slurry; feeding the second slurry into an emulsifying machine for emulsification to obtain a third slurry; and (5) feeding the third slurry into a granulator, and granulating in a high tower to obtain a finished product. The invention has simple process, can reduce the production cost and can prolong the quality guarantee period of the fertilizer. The disadvantage of this patent is that the preparation process of the drying agent and fertilizer is complicated and the energy consumption is high.
There is a need to develop a non-drying agent, which changes the free water in the granules into binding water by adding the non-drying agent, so as to reduce the free water in the granules after granulation, thereby realizing the preparation process of the non-drying fertilizer.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a non-drying agent for organic fertilizers and biological fertilizers. The drying-free essence has strong water absorption capacity, and can change free water in fertilizer or other raw materials into crystal water, thereby playing a drying-free effect.
The second purpose of the present invention is to provide a method for preparing the above-mentioned kafirin.
The invention also aims to provide the application of the drying agent in the drying-free preparation of organic fertilizers and biological fertilizers.
An organic fertilizer and biological fertilizer drying-free element comprises the following components in parts by weight:
10 parts of calcium sulfate, 5-9 parts of magnesium sulfate, 6-8 parts of calcium chloride and 20-25 parts of filler.
Preferably, the organic fertilizer and the biological fertilizer baking-free essence comprise the following components in parts by weight:
10 parts of calcium sulfate, 7 parts of magnesium sulfate, 8 parts of calcium chloride and 22 parts of filler.
Wherein the filler is biochar, fly ash or kaolin, and preferably biochar.
Biochar (english: Biochar) is a charcoal used as a soil conditioner, can help plant growth, can be applied to agricultural use and carbon collection and storage, and is different from the conventional charcoal generally used as a fuel.
5-7 parts of sodium carboxymethylcellulose can be added into the non-drying agent to play a role in absorbing and storing water.
The preparation method of the invention comprises the following steps: weighing the components and mixing uniformly.
The using method of the invention is as follows: when the biological organic fertilizer is prepared, the biological organic fertilizer is blended and added together, the water absorption capacity of the biological organic fertilizer is strong, and free water in the fertilizer or other raw materials can be changed into crystal water, so that the drying-free effect is achieved, and the biological organic fertilizer can be used as a slow release fertilizer.
Detailed Description
The present invention is further illustrated by the following examples, which are not intended to be limiting. In the examples the filler is biochar.
Example 1
An organic fertilizer and a bio-fertilizer baking-free element are prepared from the following components in parts by weight:
10 parts of calcium sulfate, 7 parts of magnesium sulfate, 8 parts of calcium chloride and 22 parts of filler.
Example 2
10 parts of calcium sulfate, 8 parts of magnesium sulfate, 7 parts of calcium chloride and 23 parts of filler.
Example 3
10 parts of calcium sulfate, 9 parts of magnesium sulfate, 6 parts of calcium chloride and 20 parts of filler.
Example 4
10 parts of calcium sulfate, 6 parts of magnesium sulfate, 7 parts of calcium chloride and 24 parts of filler.
Example 5
An organic fertilizer and a bio-fertilizer baking-free element are prepared from the following components in parts by weight:
10 parts of calcium sulfate, 7 parts of magnesium sulfate, 8 parts of calcium chloride, 22 parts of filler and 5 parts of sodium carboxymethylcellulose.
The preparation method of the embodiment of the invention comprises the following steps: weighing the components and mixing uniformly.
The application tests of examples 1 to 5 of the present invention are as follows:
a preparation method of a drying-free organic fertilizer sequentially comprises the following steps:
(1) fermenting the plant material: cutting plant straw to 2-5cm, adjusting water content to about 39%, adding distiller's grains, cellulase and wheat bran, fermenting at 60-65 deg.C for 8 days while stirring for 3 times;
wherein the weight ratio of the plant straws, the vinasse, the cellulase and the wheat bran is 50: 20: 1: 15;
(2) preparing an organic fertilizer: adding 7 parts of macroelement fertilizer, 8 parts of medium element fertilizer and amino acid: 5 parts of filler, 80 parts of baking-free agent and 25 parts of baking-free agent are fed into a pulverizer to be pulverized, granulated by a disc machine and screened to obtain finished organic fertilizer and composite microbial fertilizer;
wherein the macroelement fertilizer is selected from one or more of nitrogenous fertilizer, phosphate fertilizer and potash fertilizer;
wherein the secondary element fertilizer is selected from one or more of calcium fertilizer, magnesium fertilizer and sulfur fertilizer;
wherein the filler is selected from biochar, fly ash or kaolin.
Wherein the bakelite is the bakelite of examples 1-5.
The organic fertilizer obtained in the above embodiment does not need to be dried, and in the embodiment 5, because the sodium carboxymethyl cellulose is added, the hygroscopicity is better, and the shelf life of the fertilizer is longer. The drying-free essence has strong water absorption capacity, can change free water in fertilizer or other raw materials into crystal water, thereby playing a drying-free effect and being used as slow release fertilizer. When in use, the operation process is simple, chemical drying and full-nutrition controlled release are adopted in the preparation process, secondary pollution is avoided, the nutrient utilization rate of the fertilizer can be improved by about 10%, various medium and trace elements can be supplemented, and meanwhile, microbial strains and biochar can improve various soil-borne diseases such as soil, salinization heavy metal pollution and the like.
