Description
Technical field
The present invention relates to technical field of fertilizers, particularly relate to a kind of cold-resistant 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
