Description

A kind of property of medicine oxygen supplement coated fertilizer
Technical field
The present invention relates to technical field of fertilizers, particularly relate to a kind of property of medicine oxygen supplement coated fertilizer.
Background technology
Along with global climate is abnormal, some areas heavy rain, flood frequently occur, because of improper irrigation or draining the most not The factor such as good often results in crop arable land hydrops waterlogging, makes soil be in waterflooding state, and under flooding condition, in soil, gas is forced Discharge, easily cause oxygen in soil not enough.And oxygen is that root system of plant breathing is necessary, long term hypoxia can make plant cell Electron transmission is obstructed, and active oxygen accumulates in a large number, and membrane structure and function are destroyed, and even there will be crop mortality. Under Hypoxia Stress, root system accumulates the noxious substances such as a large amount of ethanol, lactic acid, and root system metabolism disorder, aerobic respiration is suppressed and causes Energy supply lacks, and the impact absorption to nutrient, waterflooding causes the minimizing of root system oxygen supply, also can cause plant leaf blade pore Closing, stomatal conductance reduces, and in turn results in net photosynthetic rate, the reduction of photochemistry quantum efficiency, and in blade, total leaf is green simultaneously Element and Chlorophyll-a Content decline, and cause the minimizing of plant growth and total biomass, affect greatly crop yield.For Case above, common solution is chesson or enriches oxygenating agent, and the former amount of labour is relatively big, latter increases production Cost, is all not carried out preferable economic benefit.
Research shows, under waterflooding anoxia condition, in plant cell, proline content is exponentially increased, and remains thin with this The turgescence of born of the same parents, protective enzyme and membranous system escape injury, and proline can be alleviated to a certain extent as a kind of osmotic adjustment The anoxia injury effect to cell membrane.Laxogenin is structurally similar to Study on Brassinosteroids, and obtains into This is the cheapest compared with brassinosteroid, Laxogenin can induce soluble sugar in plant, soluble protein, Proline long-pending Tired, Premeabilisation of cells regulating power can be strengthened under waterflooding anoxia condition, make cell maintain a constant turgescence, thus maintain The physiological and biochemical activities relevant with turgescence such as cell growth, stomatal opening and photosynthesis are smoothed out.And Laxogenin Polyradical can be removed by improving oxidase system activity, reduce autoxidation rate, and then reduce membrane lipid The integrity of extent of peroxidation, protecting film structure and macromolecular substances structure, and then keep the stability of cell to carry with vigor Its anoxia resistance high.Meet water after being meanwhile blended with hydrogen peroxide by carbamide and can slowly release the feature of oxygen, by upper State in the preparation being applied to fertilizer, soil epiliminion dissolved oxygen amount can be improved, increase the active o content in the soil liquid, think root The oxygen needed for providing is breathed by system, can prevent again the adverse effect to crop under waterflooding anoxia condition, and then improve crop yield, Increase planting benefit.
The application for a patent for invention of Publication No. 104045386A discloses a kind of hyperoxic plant organic fertilizer, this fertilizer Material is made up of the raw material of following parts by weight: bean cake 20-40 part, cottonseed meal 10-20 part, sugar slag 5-10 part, silicon dioxide 4-8 Part, coal humic acid 5-10 part, manioc waste 20-30 part, shale 7-14 part, plant ash 4-8 part, plant mushroom waste soil 20-30 Part, maltose residues 5-10 part, Semen Maydis grit 5-10 part, Ramulus et folium taxi cuspidatae 3-9 part, Os Sus domestica powder 7-12 part, bulls powder 8-14 part.This invention fertilizer Nutrient content is higher, and fertilizer efficiency is very fast, but is not effectively improved the oxygen content of soil plough horizon, also cannot for unfavorable conditions such as waterflooding Improve the repellence of crop, and without the raising of notable surcharge, limit the use of fertilizer.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of property of medicine oxygen supplement coated fertilizer.
The present invention is achieved by the following technical solutions:
A kind of property of medicine oxygen supplement coated fertilizer, is prepared by the raw materials in: Rhizoma Zingiberis Recens slag 13-15, EM microbial bacterial agent 2-3, Tobacco leftovers 33-35, sesame cake meal 25-28, Folium Ipomoea powder 10-12, oligo-chitosan 1-2, cobalt chloride 1-2, ammonium nitrate Calcium 3-5, oyster shell powder 4-5, carbamide 12-14,30% hydrogenperoxide steam generator 18-19, Laxogenin powder 1-2, butyl acrylate 0.5-0.6, sodium dihydrogen phosphate dry powder 1-2, nano zine oxide 1.2-1.5, water are appropriate.
Specifically comprising the following steps that of described property of medicine oxygen supplement coated fertilizer preparation method
(1) Rhizoma Zingiberis Recens slag, EM microbial bacterial agent, tobacco leftovers, sesame cake meal, Folium Ipomoea powder mixing are placed in fermentation vat, Control the 38-42% that water content is fermentation heap maximum water holding capacity, in retting fermentation 2-3 week, after having fermented, fermentation material is dried, powder It is broken into siccative standby;
(2) 25-30 times of mixture quality is joined after being mixed with oligo-chitosan, cobalt chloride by Laxogenin powder In water, it is heated to 52-56 DEG C, is incubated and is stirred continuously 30-40 minute, be down to room temperature afterwards, then be added thereto to step 1 gained Siccative, soaks and stirs 4-6 hour, filters after completing, and collects filtrate and filtrate respectively, and it is standby for powder that filtrate is dried pulverizing With;
(3) carbamide is put in 30% hydrogenperoxide steam generator, then is added thereto to sodium dihydrogen phosphate dry powder, be warming up to 30-32 DEG C, Reacting 50-60 minute, period is constantly stirred, and has reacted and has been placed on subzero 3-5 DEG C of crystallization, after drying by gained material with Step 2 gained powder, calcium ammonium nitrate, oyster shell powder mixing granulation, obtain nuclear core fertiliser granulates standby;
(4) step 2 gained filtrate is sufficiently mixed with butyl acrylate, nano zine oxide, stirs, obtain coating nutritional solution, Being placed in fluidized bed coating equipment by step 3 gained nuclear core fertiliser granulates, control inlet temperature and be 52-55 DEG C, leaving air temp is 35-37 DEG C, coating nutritional solution flow velocity is 2-2.5 ml/min, and coating nutritional solution is coated uniformly on nuclear core fertiliser granulates table Face, obtains coated fertilizer of the present invention.
The invention have the advantage that
Oxygen supplement coated fertilizer of the present invention passes through the peplos effect release with slow-release oxygen gas, it is ensured that crop root aerobic respiration Be normally carried out, for the various physiological metabolism of plant provide energy, enhance crop cell activities of antioxidant enzymes simultaneously, and reduce nothing Oxygen breathes the noxious substance the produced injury to plant, can maintain stable cellularity to a certain extent, and then improve leaf Sheet activities of antioxidant enzymes, alleviates the accumulated active oxygen injury to plant under waterflooding anoxia condition, has strengthening crop resistance to overhead flooding injury Positive role.
It is former that fertilizer of the present invention with the addition of the antibacterial anthelmintics of multiple biotype such as tobacco leftovers, Rhizoma Zingiberis Recens slag and microbial bacterial agent Material, nicotine contained therein and beneficial microbe etc. can effectively suppress the activity of pathogen and insect, create suitable for crop growth Microenvironment, the effect of nutritional supplementation can not only be played, and spraying of part chemical pesticide can be replaced, it is ensured that soil and crop Safety, play medicine fertilizer dual function.
