Description
Technical field
The invention belongs to fertilizer fields, and in particular to a kind of slow-release bio medicine fertilizer.
Background technology
Biological medicine fertilizer is to be formulated pesticide and fertilizer according to a certain percentage by biotechnology to mix, and by certain
Fertilizer and pesticide are stable in specific compound system technology and the novel ecological compound fertilizer that is formed, generally with fertilizer
Make the carrier of pesticide.For the sustainable development of Modern Agricultural, medicine fertilizer with powerful technology come what is supported and drive for being showed
Generation agricultural is a kind of new trial.Medicine fertilizer can be such that two operating procedures in field are combined into one, this not only saves labour, and
And reduce the consumption of time and the energy.In the last hundred years, agricultural production excessively relies on chemical fertilizer and pesticide, and chemical fertilizer abuse causes
The waste of a large amount of non-renewable energy resources, farmland soil qualitative change is bad, and fertility declines, and crops quality reduces, and pest and disease damage increases, food and
A series of problems, such as environmental pollution and chemical fertilizer resource wretched insufficiency, becomes increasingly conspicuous.Currently, in China's soil nitrogenous fertilizer profit
Averagely only have 30% or so with rate, the utilization rate of phosphate fertilizer is less than 10%.In addition, water nutrition problem caused by unreasonable fertilising
It is on the rise.In order to reduce a large amount of applications of chemical fertilizer, utilization rate of fertilizer is improved, the improvement soil texture, crop disease is reduced and delays
Pollution of the chemical fertilizer to environment is solved, there is an urgent need to develop a kind of new-type fertilizer to substitute part agriculture chemical, maintains agricultural sustainable
Development.Biological medicine fertilizer can play controlling disease, insect pest and nontoxic to people and animals, be high-quality Agricultural product without pollution must
The standby means of production.
With the fast development of China's modern agriculture, especially green organic agricultural cultivated area constantly expands, will be specific
Microbial bacteria is dissolved into medicine fertilizer, produces and is provided simultaneously with biological pesticide, the biological medicine fertilizer of bio-feritlizer characteristic becomes current
The emphasis that chemical fertilizer production enterprise develops.Current biological medicine fertilizer mainly by some insecticide pesticides or chitosan oligosaccharide, tea oil residule etc. with
N,P,K fertilizers add microbial bacterial agent composition, although there is certain effect in actual use, current biological medicine fertilizer
Shelf-life is short, generally can only be two months or so, and overlong time can cause drug effect to reduce or fail.Therefore, a kind of guarantor is produced
Matter time longer biological medicine fertilizer has prodigious market prospects.
Invention content
The technical problems to be solved by the invention：The medicine fertile shelf-life is short at present, generally can only be two months or so, overlong time
The problem of drug effect can be caused to reduce or fail, provides a kind of slow-release bio medicine fertilizer.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of slow-release bio medicine fertilizer, is counted, which is characterized in that in parts by weight including 5 ~ 10 parts of wax gourd bark extract ﹑, 5 ~ 10 parts of medicines
Agent particle, 30 ~ 40 parts of fertiliser granulates, 20 ~ 30 parts of compound coating lotions；
The preparation of the wax gourd bark extract：According to the mass fraction, 30 ~ 40 parts of waxgourd peel is taken, is crushed, at 20 ~ 25 DEG C, by matter
Measure ratio 1：2 extract 2.5 ~ 3h with absolute ethyl alcohol, and vacuum distillation obtains medicinal extract, takes medicinal extract, in mass ratio 1：2 ~ 3 are extracted with ethyl acetate
It takes, obtains crude extract, be evaporated under reduced pressure to get wax gourd bark extract；
The preparation method of the pharmacy particle is：According to the mass fraction, 5 ~ 10 parts of boraxs, 6 ~ 13 parts of Triadimenols, 7 ~ 15 parts of increasings are taken
Agent A is imitated, co-grinding sieves with 100 mesh sieve, and collects sieving particle, extruder grain is to get pharmacy particle；
The preparation method of the fertiliser granulates is：According to the mass fraction, take 25 ~ 40 parts of urea, 10 ~ 20 parts of potassium chloride, 15 ~ 20 parts
Resistance solvent, 30 ~ 45 parts of synergist B, co-grinding sieve with 100 mesh sieve, and collect sieving particle, extruder grain is to get fertiliser granulates；
The preparation method of the compound coating lotion：It counts in parts by weight, takes 5 ~ 12 parts of hyaluronic acids, 6 ~ 10 parts of polyacrylamides
Amine, 5 ~ 12 parts of ethylene-vinyl acetate copolymers, stir and evenly mix, and 3 ~ 8 parts of surfactants, 20 ~ 30 parts of water are added after 20 ~ 30min
15 ~ 20min is stirred to get compound coating lotion.
The synergist A is polyoxyethylene ether trisiloxanes, and the synergist B is poly-aspartate.
The resistance solvent is any one in zinc chloride or copper chloride.
The surfactant is sodium secondary alkyl sulfonate and neopelex in mass ratio 3：1 ~ 2 mixing.
The preparation method of the slow-release bio medicine fertilizer includes the following steps：
It counts in parts by weight, takes 5 ~ 10 parts of winter melon extract ﹑, 5 ~ 10 parts of pharmacy particles, 30 ~ 40 parts of fertiliser granulates, be uniformly mixed,
Compound coating lotion is sprayed, it is dry to get slow-release bio medicine fertilizer.
Compared with other methods, advantageous effects are the present invention：
（1）Poly-aspartate used in the present invention can have chelation to metal ion, can enriched in nitrogen, phosphorus, potassium and trace element confession
To plant so that plant more effectively utilizes fertilizer, improves the yield and quality of crops, and can improve soil quality, gives
The good environment that insecticide plays a role is given；Medicament synergist used is organosilicone polyoxyethylene ether compound, has low table
Face tension, good malleability, permeability and emulsifying dispersivity can significantly improve the effective rate of utilization of medicine fertilizer, improve crops
Resistance, crops absorb various nutrient abilities, chesson and the quality and sustained release for improving crops；Waxgourd peel second used
Acetoacetic ester extract has significant inhibition to gibberella saubinetii cause of disease bacterium ﹑ rhizoctonia cerealis opportunistic pathogen, Exserohilum turcicum, matches
San Zuo Chun ﹑ poly-aspartates are closed, potassium chloride synergistic effect improves disease-resistant performance, enhances the absorption of nutrient；
（2）Compound coating emulsion components include hyaluronic acid used in the present invention, have very strong water imbibition, it is very big to form viscosity
Colloid make coating material not only have controlled release fertilizer performance, also have other additional functions.Hyaluronan molecule chain is in
The random coil structure of expansion can also tangle under lower concentration, form continuous three-dimensional net structure each other, have only
Special rheological properties.Hydrone is fixed on by hydrogen bond in the network of hyaluronan molecule formation, and aquation energy is passed through
Enough absorb is equivalent to hundred times of even more water of own wt, and water is not easy to remove under stress.Thus, it can reduce
Irrigation frequency.This slow releasing medicinal fertilizer not only has the ability of the sustained release nutrient of general control slow releasing medicinal fertilizer, but also is also equipped with water suction and protects
The ability of water.The surfactant being added can significantly increase the biodegradability of coating components, greatly reduce residual
Soil is stayed, avoiding makes soil degradation.Compound coating material can wrap up medicine component and fertilizer component well, avoid its with
Oxygen and water contact, extend the holding time, slow releasing function makes drug effect fertilizer efficiency more longlasting when using；
（3）Resistance solvent zinc chloride or copper chloride used in the present invention can the fertilizer such as slow-release carbamide, generate one on its mixture surface
Layer dense film package improves medicine fertilizer and absorbs, and avoid short term failure to delay its dissolving.
