Abstract
Raw materials of a slow release fertilizer used for sandy soil and matrix cultivation comprise starch resin foam particles, and a nitrogen fertilizer, a phosphorus fertilizer, a potassium fertilizer, a calcium fertilizer, a magnesium fertilizer and an iron fertilizer which are wrapped in the starch resin foam particles. Water and the nitrogen fertilizer, the phosphorus fertilizer, the potassium fertilizer, the calcium fertilizer, the magnesium fertilizer and the iron fertilizer are be well kept in the starch resin foam particles, and can be continuously supplied to plant roots and absorbed by the plant roots with the degradation of the starch resin, so the water and fertilizer utilization rate is improved.
Description
Technical field:
The present invention relates to technical field of fertilizers, particularly to a kind of for sand ground with the slow-release fertilizer of substrate culture.
Background technology:
Slow-release fertilizer is also referred to as Controlled Release Fertilizer, it is simply that the hydrophobic substance the thinnest at chemical fertilizer granule surface bag last layer makes bag
Membranization is fertile, and moisture can enter the semipermeable membrane of porous, and the nutrient of dissolving, to film external diffusion, is continuing to supply crop,
I.e. fertilizer nutrient rate of release is adjusted, according to crop demand Releasing nutrient, reaches element fertilizer providing intensity
Dynamic equilibrium with plant physiology demand.Coating urea on market, polymer-coated urea, long-term efficiency bicarbonate ammonium, CA,
CR fertilizer is exactly a type of slow-release fertilizer.
Slow-release fertilizer has the advantage that
1. fertilizer amount reduces, and utilization rate improves.Slow-release fertilizer fertilizer efficiency is longer more than 30 days than general non-peplos,
Leaching volatilization loss reduces, and fertilizer amount can reduce 10 20% than conventional fertilizer application, reaches cost-effective
Purpose.
2. use conveniently, saving of labor's safety.Can coordinate with quick-acting fertilizer and make base manure and disposably use, fertilising is used
Work reduces about 1/3rd, and uses safety, anti-fertilizer damage.
3. increasing both production and income.After using show fertilizer efficiency the longest, the later stage does not take off power, disease-resistant anti-fall, volume increase 5% with
On.
In the area of China's length and breadth of land, there are large-area desert, area, semidesert in the northwestward, utilizes the modern times
These areas are opened up wasteland by agricultural technology, and except water resources problem to be solved, it is also critically important problem that fertilizer keeps,
Owing to sand ground hole is big, after watering, the fertilizer major part being dissolved in water can run off along hole, causes fertilizer
Utilization rate is low, and proportion of crop planting cost is high, therefore needs a kind of slow-release fertilizer that can keep fertilizer efficiency badly.
The rise of soilless culture in recent years makes the use of substrate get more and more, many big owing to being mixed with in substrate
The perlite of granule, Vermiculitum, therefore it is similar to sand ground to the holding of fertilizer.
Starch-resin has the strongest water absorbing capacity, can absorb sole mass tens times or even the water of thousand of times,
This is that conventional any absorbent material is incomparable, and water holding capacity is the highest, after water suction, no matter applies
Great pressure is not dehydrated, and be therefore otherwise known as high water-retaining agent, and meanwhile, starch-resin can in the short time certainly
So degraded, is the material of a kind of environmental protection.As the main component of starch-resin, starch source extensively,
Cheap, be suitable for large-scale processing.
Summary of the invention:
In consideration of it, be necessary to design a kind of with starch-resin as matrix for sand ground and the slow release of substrate culture
Fertile.
A kind of for sand ground with the slow-release fertilizer of substrate culture, its raw material includes: starch-resin foam particle and shallow lake
The nitrogenous fertilizer of parcel, phosphate fertilizer, potash fertilizer, calcareous fertilisers, fertiliser containing magnesium, iron fertilizer in powder resin foam particle.
Preferably, its raw material includes: starch-resin foam particle, potassium dihydrogen phosphate, calcium nitrate, magnesium nitrate,
Ferrum oxide.
Preferably, the matter of starch-resin foam particle, potassium dihydrogen phosphate, calcium nitrate, magnesium nitrate, ferrum oxide
Amount ratio is 110:(8～21): (2～6): (2～6): (4～10).
A kind of for sand ground with the production method of the slow-release fertilizer of substrate culture, comprise the following steps:
(1) take 200～300 parts of Polyethylene Glycol and 180～240 parts of glycerol, 9～11 parts of methanesulfonic acids add with
In the oil bath interlayer retort of condensation reflux unit, heat and start agitating device, being heated to 155～165 DEG C,
Add 40～80 parts of starch, stirring reaction 40～50min, be cooled to 20～35 DEG C, send into centrifuge, centrifugal
Remove solid catalyst, obtain starch liquefacation product；
(2) above-mentioned starch liquefacation product being sent into retort 80 parts, add 1 part of water simultaneously, 0.2～0.4 part double
The kicker of the dibutyl tin laurate composition of dimethylaminoethyl ether and 0.1 part, 7 parts of silicone oil L580,
Starting agitating device, add 120～150 part 4 at 10 DEG C, 4`-methyl diphenylene diisocyanate, at 7000r/min
Lower stirring 10S, pours in mould and adds 7～19 parts of potassium dihydrogen phosphates, 2～5 parts of calcium nitrates, 2～5 parts of nitre
Acid magnesium, the powder of 3～9 parts of ferrum oxides, stir, and solidification, the demoulding afterwards obtains starch-resin foam；
(3) by foam comminutor, the starch-resin foam that previous step obtains is fabricated to particle diameter be more than or equal to
1mm and the starch-resin foam particle less than or equal to 5mm.
The present invention can be by moisture and the nitrogenous fertilizer being dissolved in moisture, phosphate fertilizer, potash fertilizer, calcareous fertilisers, fertiliser containing magnesium, iron fertilizer
Well it is maintained in starch-resin foam particle, and provides continuously along with the degraded of starch-resin
Absorb to plant root, improve the utilization rate of moisture and fertilizer.
