Abstract
The present invention discloses a biological phosphate fertilizer whose chemical nutrients content is more than 10% and a preparation method thereof. The present invention mainly solves the problem of conventional microbial fertilizer of slow and insufficient fertilizer effect. The biological phosphate fertilizer is prepared from, in weight percentage, 54% to 70% of organic material adsorbing bacillus cereus, 17.5% to 25% of ammonium sulfate, 4.5% to 9% of ammonium phosphate and 8% to 12% of potassium sulfate. The biological phosphate fertilizer can increase the content of available phosphorus in soil by 10% to 30%, can improve the utilization rate of fertilizer by more than 10% and can improve the activity of trace elements. The biological phosphate fertilizer can promote the recovery of soil aggregate and can improve soil fertility if the fertilizer is used for a long time, and the biological phosphate fertilizer is suitable for various kinds of soil and crops. With no residues and no pollution, the biological phosphate fertilizer is preferred fertilizer for producing green food.
Description
Technical field
The present invention relates to the microbial fertilizer that a plant growth is used, compound manure that especially a kind of chemical fertilizer combines with microbial fertilizer and preparation method thereof.
Technical background
For a long time, the utilization ratio of nitrogen fertilizer in agriculture, phosphate fertilizer and potash fertilizer is only about 30%, 19% and 35%, a large amount of nitrogen, phosphorus and potassium lose and contaminate environment for no reason, because chemical fertilizer uses the unreasonable groundwater pollution that causes very serious, almost make the soil pollution of all regions, vegetables quality exceeds standard 70% reason also because chemical fertilizer uses unreasonable causing.A large amount of phosphorus are formed a huge phosphorus storehouse by soil fixing in soil.Microbial fertilizer can activating soil in crop be difficult to utilize or unavailable N, P, K and in, trace element.Entered since the nineties, occurred various microbial fertilizers on the market.In recent years the patent that has occurred a plurality of microbial fertilizers aspect, as notification number 1277948 " a kind of composite microbiological fertilizer and production method thereof ", notification number is that 1277175 " green Chinese medicinal stone bio-fertilizers " and notification number are " improving the method for the bio-feritlizer phosphorus bacteria rate of recovery " of 1319575 etc., but these patented products all are to continue to use traditional microbial fertilizer production technology, though conventional microbial fertilizer has significant advantage, but also have the shortcoming that the slow and fertilizer efficiency of fertilizer efficiency is difficult to reach high yield simultaneously, general only as the chemical fertilizer subsidy with fertilizer.
Summary of the invention
The object of the present invention is to provide a kind of production method simple, cost is low, and chemical fertilizer combines with microbial fertilizer, and single-dose application can be satisfied the biologic phosphorus fertilizer of crop nutrition content demand.
Another object of the present invention provides the method for the above-mentioned biologic phosphorus fertilizer of preparation.
This kind nutrient chemical is greater than 10% biologic phosphorus fertilizer, it is characterized in that it is made up of following components in part by weight: the organic materials 54%-70% that contains bacterium; Ammonium sulfate 17.5%-25%; Monoammonium phosphate 4.5%-9%; Vitriolate of tartar 8%-12%.
Be adsorbed with bacillus cereus on the described organic materials, according to repeatedly experimental results show that: this kind microorganism live bacteria has phosphorus decomposing, strengthens the effect of element activity, and the monoammonium phosphate in the ammonium sulfate of as fertilizer sources nitrogenous source, phosphorus source, the vitriolate of tartar in potassium source all help the growth of phosphate solubilizing microorganism.
The method and the step that prepare this kind biologic phosphorus fertilizer are as follows: (1) bacillus cereus adopts the ordinary method breeding, and liquid fermentation technology adopts the deep layer liquid-state fermentation technology.Microbial strains is transferred to fermentor tank and cultivates by after the I and II enlarged culturing, substratum, the same culture propagation of culture temperature, and the air flow in the fermentor tank is by feeding with fermentation volume 1:1, and tank pressure is 0.5kg/cm
2, stirring velocity is 200T/m, fermentation time is 24-36h; (2) with the wheat that becomes thoroughly decomposed and the ratio of maize straw in 3: 1, pulverize the back and dry by the fire 2h in 60 degrees centigrade baking oven, the liquid of emitting is adsorbed and by 3 * 10 in the cooling back from fermentor tank
8Individual/g viable bacteria measures on the organism that (can add an amount of water purification dilution according to the viable bacteria amount of fermented liquid, finally guaranteeing has 3 * 10 on every g organic materials
8Individual viable bacteria and moisture content are within 15-20%) mix; (3) be the organic materials that is adsorbed with viable bacteria that has prepared of 54%-70% and three kinds of Powdered chemical fertilizer even blend of ammonium sulfate, monoammonium phosphate, vitriolate of tartar that weight proportion is respectively 17.5%-25%, 4.5%-9%, 8%-12% (chemical fertilizer needs granulation during high density) with weight proportion, packing forms the present invention behind the ageing 24h-36h.
Granular chemical fertilizer form has better influence to microorganism active under the high density.
The present invention is as a kind of new microbial fertilizer, can make available phosphorus content increase 10%-30%, utilization rate of fertilizer in the soil improve more than 10%, improve the activity of trace element, and because the present invention contains higher inorganic nutrients, result of use rapidly and obviously, long-term application can be improved the soil, promote soil aggregate recovery, increase soil fertility and sustainability; Be applicable to various soil and crop.This kind biologic phosphorus fertilizer noresidue, nuisanceless is a first-selected fertilizer of producing green food.
