Abstract
The invention discloses a production method for adding humic acid and sodium silicate in a blended fertilizer, and relates to the technical field of fertilizer production. The production method comprises the following steps: granulating humic acid through a rotating drum steam granulator, and spraying a sodium silicate water solution in the granulating process; then, adding the prepared humic acid and sodium silicate granules in the batching process of the blended fertilizer; and finally, screening, mixing, metering, and packaging to obtain the finished blended fertilizer product. According to the invention, the humic acid and the sodium silicate are added in the blended fertilizer, so that required nitrogen, phosphorus, potassium and silicon element nutrients can be provided for growth of rice, the biological activity of the humic acid can be improved, and the problems of rice planting field such as soil acidification and hardening, fertility decline, heavy metal enrichment and the like can be effectively relieved; and the rice yield can be improved obviously.
Description
Technical field:
The present invention relates to fertilizer production technology field, be specifically related to add in a kind of Bulk Blending 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 Bulk Blending 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 Bulk Blending 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 Bulk Blending Fertilizer, comprises the following steps:
(1) humic acids is joined to granulation in rotary drum steam granulation machine, spray into sodium silicate aqueous solution simultaneously;
(2) material particles of being prepared by step (1) joins in dryer dries, then cooling through cooler;
(3) humic acids of being prepared by step (2) and water glass particle, Bulk Blending Fertilizer raw material are by automatic doser batching;
(4) above-mentioned all materials are joined to cylinder round sifter and sieve, the particle that particle size diameter is 2-4mm mixes, and the particle mixing is carried out to metering packing by bucket type measuring packing scale, obtains Bulk Blending Fertilizer finished product.
The concentration of described sodium silicate aqueous solution is 25%, and additional proportion is 20%.
The additional proportion of described humic acids and water glass particle is 10%.
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.

The invention has the beneficial effects as follows:
(1) in Bulk Blending 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 Bulk Blending Fertilizer, in the batching technique of Bulk Blending Fertilizer, add humic acids and water glass particle, easy and simple to handle;
(3) in Bulk Blending Fertilizer, add humic acids and water glass and obviously improved rice yield, stimulation ratio reaches 7.5%.
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 Bulk Blending Fertilizer according to operation steps of the present invention:
(2) humic acids is joined to granulation in rotary drum steam granulation machine, spray into sodium silicate aqueous solution simultaneously;
(2) material particles of being prepared by step (1) joins in dryer dries, then cooling through cooler;
(3) humic acids of being prepared by step (2) and water glass particle, Bulk Blending Fertilizer raw material are by automatic doser batching;
(4) above-mentioned all materials are joined to cylinder round sifter and sieve, the particle that particle size diameter is 2-4mm mixes, and the particle mixing is carried out to metering packing by bucket type measuring packing scale, obtains Bulk Blending Fertilizer finished product.
Wherein, the concentration of sodium silicate aqueous solution is 25%, and additional proportion is 20%; The additional proportion of humic acids and water glass particle is 10%.
