Description
Technical field
The present invention relates to a kind of humic acids activated form Chemical Mixed Fertilizer and production method thereof, belong to fertilizer manufacture field.
Background technology
Humic acids (Humic Acid, writes a Chinese character in simplified form HA) is the polymeric organic acid be made up of aromatic series and multiple functional group thereof, is extensively present in soil, lake, river and peat, brown coal, weathered coal.The acidic functionality of humic acids closes ability as carboxyl and phenolic hydroxyl group have chela (network) to metal ion, greatly can improve the biological effectiveness of metal ion.Humic acids also has very strong biological activity, humic acids is not by means of only conditioned soil earth physicochemical character, improve fertilizer efficiency, activating soil nutrient, thus the growing environment improving crop, humic acids itself also has promotion crop root growth simultaneously, enhancing crop is to absorption, the accumulation of nutrient and transport, promote respiration, improve the activity of biological enzyme, improve the multiple biological activitys such as plant stress-resistance ability.
At present, Chemical Mixed Fertilizer system mainly produces n-p-k three elements Chemical Mixed Fertilizer, high-efficiency sustained-release add organic in production technology shortcoming, cause Chemical Mixed Fertilizer fertilizer efficiency utilization ratio low; And humic-acid kind compound manure, due to its at increase crop yield, improve in quality of agricultural product, improvement soil etc. and have good effect, organic utilization ratio can be improved, strengthen disease-resistant crops evil, resist dry morning, cold resistance, salinity and alkalinity resistance, be familiar with by peasant gradually and accept, becoming an important kind in fertilizer family.But improving soil and the biological effect of the Chemical Mixed Fertilizer adopting not activated humic acids to produce are not obvious.In weathered coal, the content of total humic acid is generally at more than 50wt%, but the content of fulvo acid is generally at 1wt% ~ 3wt%, and fulvo acid is being improved soil, is promoting plant growth, is being improved in organic utilization ratio and play very crucial effect, therefore activate humic acid material, the content improving its fulvo acid becomes the effective way promoting humic-acid kind compound manure effect.
The activation method of humic acids mainly contains acidization, alkalization method and biological fermentation process, the method activated that wherein alkalizes is applied more, in prior art, the alkaline matter of activation humic acids is mainly potassium hydroxide, salt of wormwood, sodium bicarbonate, saleratus etc., but these alkaline matters exist high, the residual unreacted alkali of cost easily causes problems such as burning seedling, and complex process, do not utilize and realize suitability for industrialized production.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of humic acids activated form Chemical Mixed Fertilizer and production method thereof.In humic acids activated form Chemical Mixed Fertilizer of the present invention, the utilization ratio that content is high, biological activity is strong, organic of fulvo acid is high, and production method is simple, and cost is low, is easy to realize suitability for industrialized production.
For achieving the above object, the present invention adopts following technical scheme:
A kind of humic acids activated form Chemical Mixed Fertilizer, is prepared from by the raw material of following weight part:
Humic acids 25-27 part, ammoniacal liquor 4-5 part, Sodium Silicofluoride 5-8 part, urea 24-27 part, monoammonium phosphate 10-12 part, ammonium sulfate 10-12 part, potassium sulfate 19-22 part, calcium powder 5-7 part, oily anti-skinning agent 0.15-0.3 part, powdery anti-caking agent 0.3-0.45 part;
Wherein, the activation method of humic acids is: mixed by weight with ammoniacal liquor by humic acids, stir, then adds the potential of hydrogen that Sodium Silicofluoride regulates material, and control ph is 7-9, then deposits 3-5 days at 35-45 DEG C of condition lower seal;
Mix with urea, monoammonium phosphate, ammonium sulfate, potassium sulfate, calcium powder again, send in tablets press and carry out granulation, then 110 ~ 130 DEG C of oven dry, cooling, be transported to after sieving in coating machine, in order to prevent product from occurring caking phenomenon in transport and storage process, so spray into oily anti-skinning agent in coating machine, add powdery anti-caking agent; Described oily anti-skinning agent and described powdery anti-caking agent are adsorbed onto the wrapped thin film in described compound fertilizer granule surface by coating, with the diffusion of the generation and saturated solution that block fertilizer salt bridge, stop fertilizer agglomeration.
In described oily anti-skinning agent, the weight percentage of vegetables oil is 80%, and (i.e. octadecanoic acid, molecular formula is C to stearic acid
18h
36o
2) weight percentage be 5%, the weight percentage of paraffin wax is 15%.
Described powdery anti-caking agent is one or more in zeolite powder, diatomite, silicon dioxide powder or pure aluminium silicate, with arbitrarily than mixing.
The order number of described powdery anti-caking agent more than 200 orders, preferably 200-400 order.
The raw material that described humic acids adopts is weathered coal, and the content >=70wt% of total humic acid in weathered coal, market is buied.
The mass concentration of described ammoniacal liquor is 10-15%, is preferably 13%.
A production method for humic acids activated form Chemical Mixed Fertilizer, comprises the following steps:
(1) take raw material by weight, mixed by humic acids with ammoniacal liquor, stir, then add Sodium Silicofluoride, stir, measure the acidity of mixture, control ph is 7-9, then deposits 3-5 days at 35-45 DEG C of condition lower seal;
(2) mixture that step (1) obtains is mixed with urea, monoammonium phosphate, ammonium sulfate, potassium sulfate, calcium powder again, send in tablets press and carry out granulation, then dry, cooling, be transported to after sieving in coating machine, in coating machine, spray into the oily anti-skinning agent of 0.15 ~ 0.3 part, add the powdery anti-caking agent of 0.3 ~ 0.45 part; Described oily anti-skinning agent and described powdery anti-caking agent are adsorbed onto described compound fertilizer granule surface by coating, and packaging warehouse-in, to obtain final product.
Beneficial effect of the present invention:
(1) the present invention is by activating humic acids, improve the content of fulvo acid in humic acids, and improve utilization ratio organic in fertilizer, water-soluble humic acids activation front 5%, about 20% is brought up to after activation, because humic acids is with the effect improving potential nutrients in utilization rate of fertilizer and activating soil, humic acids and beneficial microorganism have the effect of assisting potential nutrients in release soil.Improve the transformation efficiency of Nitrogen In Soils, phosphorus, potassium element.On the crop that breeding time is shorter, the alternative chemical fertilizer of humic acid content Chemical Mixed Fertilizer carries out single fertilization, reduces production cost.As on soybean and corn, humic acid content Chemical Mixed Fertilizer can disposablely apply as base fertilizer, does not need to topdress, both reduces investment outlay, and saves again and throws work.
(2) Remixed humic acid fertilizer granulation balling ratio of the present invention is high, product granularity is even, color good, intensity is large, the use of topdressing of Various Seasonal, different crops can be adapted to, suitability is wide, its nutritive element integrates quick-acting, long-acting, synergy, has the effect improving quality of agricultural product, suppress soil-borne disease, strengthen crop anti-adversity, promote crop precocity; Fertilizer effect of increasing production is obvious.
