Abstract
The invention relates to a fertilizer for indoor flowers and plants. The fertilizer is prepared from a urea peroxide-beta-cyclodextrin inclusion compound, urea peroxide (Perurea: CO(NH2)2.H2O2) and beta-cyclodextrin which are in effective quantities, wherein the urea peroxide-beta-cyclodextrin inclusion compound takes urea peroxide as a kernel and takes beta-cyclodextrin as an outer layer. According to the slow-release fertilizer disclosed by the invention, the oxygen content is high and can reach 17-20%; and after the fertilizer disclosed by the invention is used, the oxygen release is sustained, mild, stable and controllable and can sustain 300 hours per 100g of urea peroxide in net content. The slow-release fertilizer disclosed by the invention has the advantages that the oxygen release manner is slow, mild and stable, is stronger in activity and strong in disinfection and can be used for easily eliminating diseases and pests from potted landscapes, so that the normal survival ratio of potted plants is increased effectively; and meanwhile, the fertilizer disclosed by the invention has effects on increasing, disinfecting and cleaning indoor oxygen and has incomparable superiority compared with currently reported relevant research results and new products on the market.
Description
The present patent application is application number 201110127538.5, the applying date on 05 17th, 2011, the divisional application of denomination of invention " a kind of oxygenation slow-release fertilizer and its preparation method and application ".
Technical field
The present invention is the chemical enhancement slow release fertilizer field of holding concurrently, particularly a kind of chemical enhancement that is applicable to indoor pot ornamental plant slow-release fertilizer and preparation method thereof of holding concurrently.
Background technology
Pot flowers is as upholstery, and its oxygen discharging by photosynthesis in process of growth plays a part again very positive to HUMAN HEALTH simultaneously; Have much for the slow-release fertilizer kind of flower landscape both at home and abroad at present, and can play effective slow releasing function actively the slow-release fertilizer new variety of oxygen release there is not yet open report.Existing pot flowers applies fertilizer take inorganic fertilizer as main, and violent, the difficult amount of application of grasping of fertilizer efficiency, easily burns seedling; And fertilizer is not through special disposal, the perishable small environment pollution that causes; In pot flowers, also there is at present the application of slow-release fertilizer both at home and abroad, make fertilizer efficiency compared with stable, environmental pollution is little, but generally speaking its slowly-releasing efficiency is desirable not enough, existing slow-release fertilizer is large to potted landscape soil destructive force simultaneously, easily cause soil compaction, fertilizer efficiency decline etc. problem.
Summary of the invention
The object of the present invention is to provide a kind of fertilizer for indoor flower, this fertilizer slow release effect phase is long, also has the function of chemical peculiar smell in lasting oxygen release, increase indoor oxygen content and decontamination chamber simultaneously.
Another object of the present invention is to provide the preparation method of above-mentioned fertilizer, this preparation method's no solvent residue, inclusion temperature are low, be suitable for wetting, the inclusion of heat sensitive urea peroxide, and inclusion rate are high, inclusion compound stable, is convenient to scale production and popularization.
The object of the invention is to realize by following technical measures:
For a fertilizer for indoor flower, it is characterized in that: described fertilizer is by urea peroxide-Benexate Hydrochloride, the urea peroxide (Perurea:CO (NH of significant quantity
2)
2h
2o
2) and beta-cyclodextrin composition; Described urea peroxide-Benexate Hydrochloride be take urea peroxide as kernel, beta-cyclodextrin is outer.
For make after Term Fertilization of the present invention fertilizer efficiency rapidly, can keep again fertilizer efficiency more stable lasting simultaneously, described urea peroxide-Benexate Hydrochloride accounts for 89%-98.5%, urea peroxide and beta-cyclodextrin account for 1.5%-11%, in molar content.
In fertilizer of the present invention, the urea peroxide sum in urea peroxide and urea peroxide-Benexate Hydrochloride: beta-cyclodextrin sum=1 in beta-cyclodextrin and urea peroxide-Benexate Hydrochloride: 1, with molar ratio computing.
The above-mentioned preparation method for indoor flower fertilizer, is characterized in that: be to add in reactor after beta-cyclodextrin is mixed with urea peroxide, adopt supercritical fluid method that beta-cyclodextrin, urea peroxide are carried out to inclusion reaction; Described supercritical fluid method is with CO
2for medium.The present invention passes into supercutical fluid CO
2it is 13-18Mpa that the temperature of carrying out inclusion reaction is preferably 120-150 ℃, pressure, reaction 6-8h.
The preparation method of the above-mentioned fertilizer for indoor flower, carries out according to the following steps:
The beta-cyclodextrin that is 1: 1 by mol ratio adds in reactor after mixing with urea peroxide solid substance;
Under 150 ℃, 15MPa, keep supercutical fluid CO
2the mixture 6h of the logical urea peroxide of fluid and beta-cyclodextrin, releasing reactor pressure, isolating carbonic acid gas from top can be for recycling; Obtain inclusion compound from reactor lower part, after drying under reduced pressure, obtain oxygenation slow-release fertilizer.In the CO of supercritical state
2fluid is that a kind of mixture to beta-cyclodextrin and urea peroxide works the carrier (SCF) that dissolves homogeneous effect herein, has a supercutical fluid (SCF) that superior mass transfer ability promotes that beta-cyclodextrin-urea peroxide inclusion process is carried out again as a kind of.
The present invention is used for the application process of the fertilizer of indoor flower:
By fertilizer of the present invention and MnO
2be to mix as medicament layer, by described oxygenation slow-release fertilizer and MnO at 1: 20 in mass ratio
2the medicament layer of composition is placed on the loam layer of flower landscape, below ridging layer, by potted landscape normally the mode of watering water; Described ridging layer is for soil for potted landscape, as red beautiful soil or Java volcanics.
Water has nascent oxygen [O] at every turn ↑ be discharged in room air, simultaneously in inclusion compound urea gradually slowly-releasing go out, play permanent fertilizer efficiency.Effect mechanism of oxygenation slow-release fertilizer: slow-release fertilizer of the present invention is containing oxidation urea (CO (NH

The water-soluble reaction mechanism explanation of Benexate Hydrochloride of urea peroxide:
Inclusion compound
The present invention has following beneficial effect:
In the time being bonsai watering, fertilizer of the present invention discharge nascent oxygen [O] ↑, be equivalent to negative oxygen ion, not only increase the oxygen level of room air, and human body is had to the foster smart effect of refreshing oneself, can also play indoor disinfection, especially to the gas with foreign flavor table elimination effect in the new house of firm finishing; The urea of its slowly-releasing has also improved the survival rate of potted plant as the fertilizer of potted plant simultaneously.Slow-release fertilizer oxygen-content active amount of the present invention is high, can reach 17%～20%, than conventional percarbonic acid calcium, and SPC-D, Sodium peroxoborate, Potassium Persulphate and ammonium persulphate (oxygen level 10%～14% is put oxygen 0.5h～2h) etc. are much higher; Existing novel sustained release fertilizer, its mesolite coated urea and composite fertilizer's slow-release carbamide thereof are not put oxygen; Urea peroxide generally continues 6h～8h; And product of the present invention after using, put oxygen continue, gentle, stable, can control the sustainable 300h of 100g (net content of urea peroxide).Slow-release fertilizer of the present invention is put the slow gentleness of oxygen mode, stable and activity degree is stronger, and the strong toxicity that disappears is easily eliminated evil in the disease in potted landscape, thereby has effectively improved the normal survival rate of potted plant; Product of the present invention also has indoor oxygen-enhanced, sterilization cleaning effect simultaneously, and with the correlative study achievement of current report and the product innovation comparison of market supply, it has unrivaled superiority.
