Abstract
The present invention relates to a solid fertilizer, more specifically to a solid humic acid fertilizer, which is measured by 100 parts and prepared from components of the following composition by weight: 4 to 40 parts of nitrogen, 3 to 35 parts of phosphorus, 3 to 40 parts of potassium, 0 to 6.5 parts of secondary elements, 0 to 1.5 parts of microelements, 15 to 30 parts of active humic acid and 0 to 1.0 part of water soluble chitosan, wherein the active humic acid is provided by active weathered coal containing active humic acid. Active weathered coal is made by the following method that under the condition of agitation, 30 to 50 parts by weight of water and 4 to 7 parts by weight of active agent are added into 30 to 60 parts by weight of weathered coal, evenly agitated and then added with 2 to 10 parts by weight of catalyzed oxidation agent to simultaneously react for 3 to 30 minutes at a temperature of 10 to 60 DEG C at an agitation speed faster than 200 r/min, be dried at a temperature of 20 to 90 DEG C and pulverized into granules larger than or equal to 20 meshes to obtain active weathered coal containing active humic acid. The present invention has the advantages of high fertilizer effect, low preparation cost, no environmental pollution, etc.
Description
Technical field
The present invention relates to solid fertilizer, is a kind of humic acids solid fertilizer specifically.
Background technology
China farmland is because a large amount of chemical fertilizer of long-term application, harm such as soil compaction, salinification, pollution have been caused, and the quality taste of crop products becomes worse and worse, nitrate content severe overweight in the vegetables, threaten HUMAN HEALTH, for this reason, people advocate energetically and carry out the tangerine bar also measure such as field so that increase the amount of application of fertilizer, but the raw material of objectively producing fertilizer is very limited, does not also satisfy the needs in big area farmland.
The exploitation of humic acid fertilizer and application, increased fertilizer source channel, chemical fertilizer and fertilizer shortcoming have separately been remedied simultaneously also more satisfactoryly, that is: (1) humic acids of having activated combines with element chelatings such as the nutrient nitrogen of crop, phosphorus, potassium and chemical physics effectively, and make humic acid fertilizer promptly have quick-acting, slow and ion exchange are arranged again; (2) contain a large amount of organic matters such as humic acids in the humic acid fertilizer, play and reduce soil compaction, salinification, improve the soil, increase the effect of soil and fertilizer; (3) improve the crop and fruit quality, can make the crop and fruit quality reach the above level of pollution-free green food A level.
Relevant humic acid fertilizer documents and materials a lot (as: CN 1152564A, CN1176242A, CN1216759A, CN1212249A), domestic humic acids factory is quite a few, what " humic acids association " put on record family just arranged more than 50, but most manufacturer production technologies fall behind, be simply equipped, on activation humic acids technology, expend energy height, environmental pollution is serious, does not possess modern production technology and scale.
Summary of the invention
The object of the present invention is to provide a kind of non-environmental-pollution, fertilizer efficiency height, the humic acids solid fertilizer that preparation cost is low.
For achieving the above object, the technical scheme taked of the present invention is:
A kind of humic acids solid fertilizer, in 100 parts, its weight consists of: 4~40 parts in nitrogen, 3~35 parts in phosphorus, 3~40 parts in potassium, 0~6.5 part of moderate-element, 0~1.5 part of trace element, 15~30 parts of activated humic acids (HA), water-soluble chitosan are 0~1.0 part.
Described nitrogen is the available nitrogen content in the nitrogenous source, and nitrogenous source is urea, ammonium nitrate, ammonium sulfate, bicarbonate of ammonia and/or Dyhard RU 100; Phosphorus is the available phosphorus content in the phosphorus source, and the phosphorus source is ammonium hydrogen phosphate, potassium hydrogen phosphate, calcium superphosphate and/or double superhosphate; Potassium is the effective potassium content in the potassium source, and the potassium source is vitriolate of tartar, Repone K and/or saltpetre; Described moderate-element is Ca, Mg and/or S, and trace element is, Cu, Fe, Zn, Mo, Mn, B and/or Cl;
Described activated humic acid is provided by the active weathered coal that contains activated humic acid, active weathered coal is made by following method: under agitation condition, to parts by weight is to add the water of 30~50 parts of parts by weight, 4~7 parts activator in 30~60 parts the weathered coal, after stirring, the catalytic oxidant that adds 2~10 parts again, simultaneously with 〉=200 rev/mins stirring velocity, under 10~60 ℃ of priming reaction temperature, reacted 3~30 minutes, then, dry under 20~90 ℃, be crushed to 〉=20 purpose particles, promptly get the active weathered coal that contains activated humic acid;
The granularity of described weathered coal is more than 〉=60 orders, wherein humic acids content 〉=50%; Activator is NaOH, KOH, Na

3The time, the drying temperature of activated humic acid preparation process is a normal temperature.
When the priming reaction temperature is 25~35 ℃, when stirring velocity was 200~500 rev/mins, effect was preferable.
The preparation of humic acids solid fertilizer can be adopted ordinary method, promptly pressing the weight of humic acids solid fertilizer forms, respectively with nitrogenous source, phosphorus source and potassium source material and activated humic acid, in, trace element and water-soluble chitosan place stirred vessel, stirred 15~40 minutes, and can obtain the humic acids solid fertilizer pulvis of taupe.This fertilizer pulvis can be made into the particle that granularity is 3.35~5.6mm through extrusion machine.
The present invention has the following advantages:
1. fertilizer efficiency height.The present invention adopts the natural weathered coal that has than high humic acid content (HA content 〉=50%), use activator, Preparation of Catalyst to go out to activate humic acids, not only effectively raise the humic acids activation rate, and the humic acids that has highly activated and the needed nutritive element of plant growth (nitrogen, phosphorus, zinc, iron, manganese, copper, molybdenum, boron etc.) form chelating and binding substances, make it have slow certain controlled release ability of having immediate effect property again, significantly improved the assimilated efficiency and the utilising efficiency of fertilizer.
2. cut down the consumption of energy, non-environmental-pollution, preparation cost is low.The preparation of activation weathered coal in the humic acids solid fertilizer of the present invention, owing to adopt new production technique, promptly in priming reaction, added catalytic oxidant, feasible reaction can be carried out at normal temperatures, (priming reaction of prior art needs to carry out under 60~100 ℃), thereby the energy consumption of greatly reducing, in addition, with basic carbonate such as Na
2CO
3, K
2CO
3, NH
4HCO
3Deng being in the humic acids priming reaction of activator, because the great amount of carbon dioxide gas that generates in the reaction process makes reactant can form the porous expander, the utmost point is beneficial to the seasoning at normal temperatures of activation weathered coal, not only save the energy, reduce cost, even exempted environmental pollution.
3. effect is good, can improve crop yield, improves crop quality.Because the present invention adds chitosan (chitosan) in fertilizer, it and humic acids act synergistically, further strengthened the vigor of the intravital plurality of enzymes of crop, improved cold-resistant, the drought-resistant moisture-preserving of crop and suppressed anti-adversity ability such as harmful germ, thereby improved the output of crop; In addition, in the humic acids solid fertilizer of the present invention, owing to contain a large amount of organic matters such as humic acids, the normal phase uses, can not only play and reduce soil compaction, salinification, improve the soil, increase the effect of soil and fertilizer, and help to improve the crop and fruit quality, can make the crop and fruit quality reach the above level of pollution-free green food A level.
