Description
Technical field
The present invention relates to a kind of crop foliage fertilizer, be specifically related to a kind of containing the organosilyl plant nutrient agent of oligose.
Background technology
Rice husk is one of main byproduct of cereal processing, accounts for 20% of paddy quality, is large, wide, the inexpensive renewable resources of a kind of amount.China has at least 3.6 hundred million tons, rice husk every year.Rice husk contains multiple element.In rice hull ash, main component is SiO
2, it is mainly to exist with biomineralization form, metamict.Rice husk basal component after charing is carbon and silicon-dioxide, and or not containing heavy metal, this does not provide condition for producing agricultural Chemicals and application.Yet current people are to the inadequate science of the utilization of rice husk, reasonable, the beneficiating ingredient in rice husk can not be fully used, and has caused waste.Occurring in nature, plant absorbs some nutrient in soil again and again, just causes the disappearance of these nutrients; Particularly silicon, calcium, fertiliser containing magnesium never have artificially and supplemented, and have so just affected the development growth of plant, and further high yield.By the tested result of the Chinese Academy of Agricultural Sciences's clay fertilizer, show, siliceous fertilizer is one of necessary nutritive element in paddy rice, legume crop, growth and development of fruit tree.Executed fruit tree, beans, peanut, paddy rice of siliceous fertilizer etc., cane is sturdy, and growing way is evenly healthy, and blade is large and compact, straight and upright, plump, color and luster is dark green, chlorophyll content increases greatly, and is conducive to cold-resistantly, resists extraneous germ dip-dye.Siliceous fertilizer has " three anti-three short " effect to the high and stable yields of crop, resistant to lodging, Resistant, anti-dry early, promote to promote root growth and development by photosynthesis, promote effective utilization of nutrient.Amino acid, humic acids siliceous fertilizer have good synergistic function, than single nutrient, have better effect of increasing production, also can improve crop quality.But because element silicon chemical property determines that its most compounds are insoluble, so siliceous fertilizer is difficult to absorbed by crops and utilization veritably.China ZL98121697.8 patent of invention " a kind of containing silicon foliage fertilizer and preparation method thereof " is to utilize colloid silica to improve the utilization ratio of crop to siliceous fertilizer.Colloid silica belongs to inorganic silicon, though contain solvend, Crop and utilization ratio are still very low, and fertilizer efficiency period is short." seed amino acid, humic acids siliceous fertilizer and the production method thereof " of China CN1467 183A patent application document is to using liquid soluble glass as hydrolytic reagent, take and discard albumen as raw material, but cost of material is high, protein is processed not thorough, contain sodium ion too much, nutritive ingredient loss is serious.
Summary of the invention
The present invention will solve and lack at present high-efficiency plant nutrition agent, and can not make full use of the problem that rice husk is produced high-efficiency plant nutrition agent, provide of the present invention a kind of containing the organosilyl plant nutrient agent of oligose for this reason, this nutrition agent is easy to absorbed by crops, and utilization ratio is high, fertilizer efficiency period is long, has no side effect.
For addressing the above problem, its special character of the technical solution used in the present invention is to take described nutrition agent weight to contain as benchmark: oligose 0.1～4%, humic acids 1～10%, urea 0～50%, saltpetre 0～15%, potassium primary phosphate 0～15%, dipotassium hydrogen phosphate 0～30%, trace element accounts for 0.1～5%, plant-growth regulator 0.1～5%, organosilicon extracting solution 10～80%, surplus is water;
Described organosilicon extracting solution is made by following steps: rice husk, microbiobacterial agent, water are mixed into rice husk/microbial inoculum/water mixture, and the described compound weight of take is benchmark, rice husk 50～75%, and microbial inoculum 0.5～1.5%, surplus is water; Described compound fermentation becomes the rear compound of fermentation for 72 hours, after described fermentation, compound adds the lixiviate of 20% (W/W) NaOH solution, after described fermentation, the mass ratio of compound and NaOH solution is 3.5: 1,90 ℃ of extraction temperatures, extraction time 5 hours, filter and remove residue after lixiviate (should adopt centrifuging), obtains tan organosilicon extracting solution;
Described microbial inoculum is subtilis, bacillus laterosporus and saccharomycetic composite fungus agent, and three's weight ratio is subtilis/bacillus laterosporus/yeast=(50～80)/(0～50)/(0～35).
Described oligose is the composition of two or more (containing two kinds) in xylo-oligosaccharide, oligomeric soya sugars, IMO.
Described plant-growth regulator is the composition of two or more in sodium nitrophenolate, α-naphthaleneacidsodium, rape element (containing two kinds).
Described microbiobacterial agent is the composition of two kinds in subtilis, bacillus laterosporus, cereuisiae fermentum above (containing two kinds).
After fermentation of the present invention, compound is 8-9 through the lixiviate of NaOH solution, filter and remove residue gained filtrate tune PH, is described organosilicon extracting solution; Wherein lixiviate is that alkali is slightly excessive, can adjust PH by adding citric acid.
Organosilicon extracting solution of the present invention is through adopting < < People's Republic of China (PRC) agricultural industry criteria. and the detection method in siliceous fertilizer (NY/T 797-2004) > > is measured, and described organosilicon extracting solution is containing silicon-dioxide 20-32.6%.
The most basic chemical fertilizer of plant is nitrogenous fertilizer, phosphate fertilizer and potash fertilizer.In the present invention, urea is nitrogenous fertilizer; Saltpetre, containing element N and K, is nitrogen-K composite fertilizer; Dipotassium hydrogen phosphate and potassium primary phosphate, containing element P and K, are phosphorus-K composite fertilizer.
Trace element in the present invention is trace element fertilizer, is called for short micro-fertilizer.
The present invention is containing plant-growth regulator (Plant growth regulator).Plant-growth regulator refers to. the material with coordinate plant growth growth and other functions contained or synthetic in plant.
The present invention is dissolved in water after oligose, humic acids, nitrogenous fertilizer, composite microbial fertilizer and plant-growth regulator are mixed in proportion, then adds the water of organosilicon extracting solution and surplus, makes plant nutrient agent of the present invention.The invention has the advantages that:
1, rice husk is got filtrate through microbiobacterial agent glycolysis, soda boiling (alkali lye heat lixiviate), centrifuging, extracts organosilicon, and pollution-free, nutritive substance loss is few, cost is low, active high, is easy to plant and absorbs, and can improve utilization rate of fertilizer, fertilizer efficiency period is long, has no side effect.
2, the present invention is except nitrogenous, phosphorus, potassium and micro-fertilizer, and containing oligose, humic acids, plant-growth regulator, therefore complete function, wide spectrum, there is coordination crop growth, improve sugar, protein, nucleic acid content in plant materials, strengthen the activity of nitrate reductase, increase the accumulation of dry-matter, water balance in control agent, promotes the effects such as crop is precocious, degeneration-resistant, volume increase.
3, containing proposing the present invention of effective substance, siliceous fertilizer and synergistic matter compatibility, can improve plant cold resistance and stalk lodging resistance, balanced in nutrition, makes the various nutritive elements can be really absorbed by crops, reaches the quick-acting and long-acting feature of taking into account, and amount of increase in production is large.
