Abstract
Pyrolysis bio-oils produce humic acid fertilizer bonding coating agent, and raw material proportioning is：Clear water 5 10, pyrolysis bio-oils 60 80, urea 5 15, film forming rubber powder 5 20, trace meter fertilizer 15；Production technology is, according to raw material proportioning, 50 95 DEG C to be heated to after bio oil is added into reactor, adds urea, in 20 200 revs/min of rotating speed stirring reaction 15 80 minutes, it is subsequently adding film forming rubber powder, trace element fertilizer to stir, adds the emulsification of water strong stirring, forms uniform mixed liquor；Course of reaction is finished, then isolates insoluble matter by filter centrifugal, the reaction solution for leaching as humic acid fertilizer bonding coating agent.
Description
1. technical field
The present invention provides pyrolysis bio-oils and produces humic acid fertilizer bonding coating agent, is related to chemical fertilizer upgrading synergy, especially relates to
And the bonding coating preparation and the production method of bonding coating preparation of nitrogen phosphorus potassium slow release fertilizer.
2. background technology
According to ASSOCIATE STATISTICS, chemical fertilizer input accounts for peasant and carries out 50% or so of the total input of planting industry production, developing country
50% comes from the effect of chemical fertilizer in increases in grain production.But current China this season utilization rate of nitrogen fertilizer is only 20%~35%, phosphate fertilizer
Utilization rate is 10%~20%, and the utilization rate of potash fertilizer is 30%~60%, and level is utilized far below World Developed Countries.Fertilizer profit
With the low huge waste for not only causing resource of rate, return environment for the survival of mankind and cause severe contamination.
Misfitted with plant nutrient absorption rate to solve fertilizer nutrient rate of release, improve asking for utilization rate of fertilizer
Topic, 20 beginnings of the century propose the concept of slow release fertilizer.Sustained-controll-release fertiliser refers to fertilizer nutrient rate of release slow, acquisition time compared with
It is long, the fertilizer of plant growth demand can be met in the whole growth period of crop, it is to improve having for npk fertilizer utilization rate
Effect means, have become new focus in fertilizer circle research field.
Sustained-controll-release fertiliser is presently mainly coated fertilizer, mainly carries out coating with wax, polymer and sulphur, it is also possible to use
The coatings such as pitch, portland cement ammonium magnesium phosphates, are exactly to coat half water penetration or not in granular water soluble (quick-acting) fertilizer surface
Water permeable material, makes nutrient largely be released by micropore, the gap slow release of coating out, or in a certain growth phase of crop
Put, absorbed by crop, so as to reduce nutrient loss, improve utilization rate of fertilizer.Such as
(1) sulfur coated urea
In coated fertilizer, sulfur coated urea occupies special status.This is coated fertilizer mainly due to sulphur in itself
Nutrient, and cost is relatively low.The general nitrogen content of sulfur coated urea is 36~37%.Sulfur coated urea is applied to growth period work long
Paddy rice under the conditions of thing, such as herbage, sugarcane, pineapple and intermittent irrigation, but it is unsuitable for the crop of fast-growth, such as corn
Etc.Sulfur coated urea can be doubled than the effective rate of utilization that common urea is absorbed by crops, sulfur coated urea as paddy rice nitrogen
Source is promising, the grain yield that some sulfur coated ureas are obtained, hence it is evident that higher than the grain yield obtained using urea.
(2) urea of coated with resin
The urea of coated with resin is, using a variety of resin materials, mainly due to release slowly, to play long-acting and slow
Effect, it is possible to reduce the number of times that some crops are topdressed, corn can realize one-time use base fertilizer using long-acting carbamide, change with
Toward the inconvenience topdressed in toy trumpet mouthful phase or typhon mouthful phase, fertilizer can be once used sufficient in rice transplanting in rice terrace can subtract
The carrying out of few repeatedly effect.On vegetables, particularly the vegetables of some plastic film mulching cultivations can be reduced using long-acting (slow) fertilizer
The utilization rate that the number of times of fertilising improves fertilizer saves fertilizer.Result of the test shows that using coated urea conventional amount used can be saved
50%.But the crux of resin coated urea is the uniformity and controllability of coating and the stability of covering, there are some coatings to urinate
Plain covering is very crisp or even the effect for influenceing to be coated that comes off is easy in transportation, and the uneven distribution of coating is even, rate of release
Different is also a factor of influence coated carbamide application effect.Current coated carbamide there is also an issue, some coatings
Process is more complicated, coating material price is higher, too high by increasing cost after coating.The range of application of fertilizer is influenceed,
Some coated fertilizers do not allow in soil it is degradable, it is long-term continuous using the pollution that will also result in soil environment, destroy soil
Physical behavior, urgent need to resolve is degradable, the inexpensive coated fertilizer mutually melted with soil.Such as the coated fertilizer of humic-acid kind.
Humic acid is the remains of animal and plant by the decomposition and conversion of microorganism and a series of mistakes of physical chemistry of the earth
Journey and the class macromolecular organic monoacid mixture that is formed, maintain various constituents nature and bioactivity and its
Abundant functional group, such as aromatic rings, conjugated double bond, hydroxyl, carboxyl, phenolic hydroxyl group, carbonyl, being capable of improved soil structure, raising
Fertilizer efficiency；Water-swellable, dehydration shrinkage, are the fertilizer coating high-quality raw materials for realizing that liquid manure is unified simultaneously.But mineral resources humic acid is
The main source of current humic acid product, because raw material active principle content is low, active function groups solidification, it is necessary to activate with it is pure
Change, consume more alkali and acid, produce substantial amounts of organic wastewater with high concentration, production cost is high, how low from mineral resources humic acid material
