The production method comprises the following steps: firstly, metering and proportioning raw materials of the organic-inorganic mixed fertilizer and humic acid, fully mixing and grinding; secondly, granulating in a rotary drum steam granulator, and spraying a sodium silicate aqueous solution in a granulating process; finally, drying, cooling, screening, metering and packaging to obtain the finished organic-inorganic mixed fertilizer. According to the production method, humic acid and sodium silicate are added into the organic-inorganic mixed fertilizer, so that required nitrogen, phosphorus, potassium and silicon nutrients can be provided for growth of paddy rice, the solubility and bioactivity of humic acid are improved, the pelletizing rate of the mixed fertilizer is increased, and the yield of the paddy rice also can be remarkably increased.
Description
Technical field:
The present invention relates to fertilizer production technology field, be specifically related to add in a kind of compound organic and inorganic fertilizer the production method of humic acids and water glass.
Background technology:
In rice crop process of growth, a large amount of and life-time service compound organic and inorganic fertilizer, can reduce the anti-adversity ability of paddy rice, comprises Resistant, resistant to lodging, cold-resistant, drought resisting etc., causes the paddy rice underproduction and product quality reduction; Also can cause soil acidification and harden, fertility declines simultaneously; Heavy metal accumulation in fertilizer also can cause food safety hidden danger in addition.Therefore, solve the soil acidification in agricultural land and harden, fertility declines, and heavy metal (plumbous Pb, mercury Hg, arsenic As, cadmium Cd, chromium Cr) enrichment causes the serious problems of food safety, is the task of top priority that agriculture production develops in a healthy way.
Water glass can not only strengthen paddy rice anti-adversity ability, improve photosynthesis, prevent crop early ageing, improve fertilising benefit, reduce pollution of area source, and meet the nutrient uptake feature of paddy rice.And humic acids not only can strengthen the physiological vigor of farm crop, resistibility to poor environment, improve agricultural product quality, and can improve utilization rate of fertilizer, protect nitrogen, phosphorization, activation potassium and trace element, the absorption of strengthening nutrient.Within the time of infertility of crop, offer continuously the required various nutrients of plant growth, the later stage is difficult for de-fertile.
Summary of the invention:
Technical problem to be solved by this invention is to provide that a kind of production technique is simple, cost is low and can effectively improve the production method of adding humic acids and water glass in the compound organic and inorganic fertilizer of rice yield.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A production method of adding humic acids and water glass in compound organic and inorganic fertilizer, comprises the following steps:
(1) compound organic and inorganic fertilizer raw material and humic acids, by automatic doser batching, then fully mix all materials;
(2) material mixing is joined in pulverizer and pulverized, the raw meal particle size after pulverizing is less than 1mm;
(3) material crushing is joined in rotary drum steam granulation machine and carries out granulation, in granulation process, spray into sodium silicate aqueous solution;
(4) material particles of being prepared by step (3) joins in dryer dries, then cooling through cooler, finally enter cylinder round sifter screening, the particle that is 3-4mm by granularity carries out metering packing by bucket type measuring packing scale, obtains compound organic and inorganic fertilizer finished product.
Described humic acids adds with dry-matter form, and additional proportion is 10%.
The concentration of described sodium silicate aqueous solution is 25%, and additional proportion is 5%.
The mechanism of action that water glass and humic acids are combined use is as follows:
Water glass (Na
2o.nSiO
2) be strong base-weak acid salt, in the aqueous solution, after hydrolysis, be weakly alkaline, pH value scope is 9～10; Humic acids is made up of Ulmic acids, ulmic acid and xanthohumic acid, under acidic conditions, only has xanthohumic acid solubilized, and in pH value 9～10 o'clock, humic acids can dissolve completely.
OH
-+ humic acids (water-insoluble) → humic acids (water-soluble)
The hydroxide ion that water glass hydrolysis produces can react with heavy metal lead Pb, mercury Hg, arsenic As, cadmium Cd, chromium Cr in soil and generate water-fast precipitation.

In the proportioning process of compound organic and inorganic fertilizer, add humic acids, in granulation process, add water glass, the solvability of humic acids is improved greatly, also improved the biological activity of humic acids; Water glass has characteristic sticky and effect simultaneously, has also improved the balling ratio of organic-inorganic compound fertilizer.
The invention has the beneficial effects as follows:
(1) in compound organic and inorganic fertilizer, add humic acids and water glass, not only can provide required nitrogen, phosphorus, potassium nutrition for paddy growth, element silicon nutrient is provided, improves the biological activity of humic acids, and the soil acidification that can effectively alleviate Rice Cropping ground hardens, fertility declines and the problem such as heavy metal accumulation;
(2) from the production technique of compound organic and inorganic fertilizer, in adding humic acids, spray sodium silicate solution, improved on the one hand solvability and the biological activity of humic acids, on the other hand, improved the balling ratio of compound organic and inorganic fertilizer.Like this, not only improve class's output, and saved the energy consumption that compound organic and inorganic fertilizer is produced, reduced production cost.
(3) in compound organic and inorganic fertilizer, add humic acids and water glass and obviously improved rice yield, stimulation ratio reaches 11.6%.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
Carry out the preparation of compound organic and inorganic fertilizer according to operation steps of the present invention:
(1) compound organic and inorganic fertilizer raw material and humic acids are by automatic doser batching, and humic acids adds with dry-matter form, and additional proportion is 10%, then all materials is fully mixed;
(2) material mixing is joined to chain type pulverizer and pulverize, the raw meal particle size after pulverizing is less than 1mm;
(3) material crushing is joined in rotary drum steam granulation machine and carries out granulation, spray into concentration and be 25% sodium silicate aqueous solution in granulation process, additional proportion is 5%;
(4) material particles of being prepared by step (3) joins in rotary dryer dries, then cooling through rotary cooler, finally enter cylinder round sifter screening, the particle that is 3-4mm by granularity carries out metering packing by bucket type measuring packing scale, obtains compound organic and inorganic fertilizer finished product.
The balling ratio of compound organic and inorganic fertilizer has determined the output capacity of product.Output capacity is higher, and the production time, coal consumption, power consumption of ton product are just lower.The balling ratio statistics of the prepared compound organic and inorganic fertilizer of the present invention is as shown in table 1:
Table 1 compound organic and inorganic fertilizer balling ratio statistics
