Abstract
The invention provides a kind of preparation method and application of rhodotorula glutinis bio-organic fertilizer.The method obtains rhodotorula glutinis thalline for raw material to ferment, first dry thalline under 40-80 DEG C of condition, is applied to the growth of soybean or kidney bean after then being pulverized by dry thalline using the amount of application of per hectare 150-450kg as base fertilizer.In the present invention, rhodotorula glutinis has the distinguishing features such as preparation method is simple, amount of application is little as bio-feritlizer, both for rhodotorula glutinis provides a kind of novelty teabag, also can reduce the environmental pollution that causes because excessively using chemical fertilizer and affect the problems such as human health.
Description
Technical field
The present invention relates to a kind of preparation method of microorganism organic fertilizer, particularly a kind of rhodotorula glutinis is as the application of bio-feritlizer.
Background technology
Rhodotorula glutinis (Rhodotorulaglutinis), because the plurality of active ingredients such as carotenoid, lipid acid, amino acid, ubiquinone, phenylalanine ammonia lyase can be produced, receive much concern in recent years, be considered to industrialization potential bacterial strain, be widely used in preparing the fields such as animal-feed, agriculture fruit biological control of diseases, biological medicine and bioenergy.As Heilongjiang Dahuangchuan Wine Co., Ltd. discloses the method (number of patent application: 201010251117.9) that rhodotorula glutinis prepares animal-feed; Zhejiang University discloses the method (application number: 201110111499.X) that rhodotorula glutinis prepares biological preservative for oranges; Method (the number of patent application: 201010509822.4) of rhodotorula glutinis preparation (S)-hydroxypropanamide disclosed in Chinese science research institute Chengdu biology; Beijing University of Chemical Technology discloses the method (application number: 201110095230.7) etc. that rhodotorula glutinis production microbial oil prepares biofuel.But the method utilizing rhodotorula glutinis to prepare bio-organic fertilizer is not then reported.
The long-term application of current chemical fertilizer brings serious agricultural soil and pollutes (as soil acidification, harden, heavy metal contamination etc.) and agricultural-food and can not to guarantee the quality problems such as (as " melon are sweetless, and dish is not fragrant, really tasteless, and beans are poisonous ").And microbial fertilizer can be improved soil physical and chemical property, strengthen water retention capacity, improve and continue feeder capability and strengthen disease-resistant crops evil ability, therefore the application of microorganism organic fertilizer becomes a kind of and supplements and the inexorable trend of alternative chemical fertilizer.
Summary of the invention
The object of the invention is the preparation method providing rhodotorula glutinis bio-feritlizer; The object of the invention is also the novelty teabag providing rhodotorula glutinis as bio-organic fertilizer.
The present invention seeks to be achieved through the following technical solutions:
The methods for making and using same of rhodotorula glutinis fertilizer of the present invention is:
Rhodotorula glutinis fungus press after the inoculation of 5-15% pH5-6, temperature 25-35 DEG C, the condition bottom fermentation 18-48h of air flow 0.2-1.0vvm obtains using sticky red rhodotorula liquid; Then bacterium solid and liquid is separated and obtains bacterium mud in 40-80 DEG C of drying treatment acquisition bacterium block; Be 150-450kg by 1 hectare of amount of application every after acquisition bacterium block pulverization process afterwards, use in the mode of base fertilizer.
The methods for making and using same of rhodotorula glutinis fertilizer of the present invention is preferably:
Rhodotorula glutinis fungus obtains using sticky red rhodotorula liquid by after the inoculation of 10% at the condition bottom fermentation 36h of pH5.5, temperature 30 DEG C, air flow 0.8vvm; Then bacterium solid and liquid is separated and obtains bacterium mud in 50 DEG C of drying treatment acquisition bacterium blocks; Be 180kg by 1 hectare of amount of application every after acquisition bacterium block pulverization process afterwards, use in the mode of base fertilizer.
Specific embodiment is used for further illustrating but is not limited to the present invention below.
Embodiment 1 is that fermenting raw materials produces rhodotorula glutinis fertilizer application in the growth experiment of soybean with food and drink waste water
With Beijing Agricultural College student second dining room waste water for raw material substratum, Rhodotorula glutinis fungus 5% is inoculated in 5L fermentor tank, 300rpm, obtaining biomass after 1vvm fermentation 40h is the fermented liquid of 14g/L, and 60 DEG C of oven dry select soybean as experiment material after pulverizing, with vermiculite as potted plant substrate, using with the amount of application base fertilizer of per hectare 450kg, is contrast with the commercially available compound nitrogen phosphate fertilizer of equivalent, plant 7 days afterwards respectively thick the and plant height in periodic measurement footpath to test fertilizer efficiency.
Experimental result: rhodotorula glutinis utilizes food and drink waste water fermentation 18h artifact amount just can reach more than 10g/L as seen from Figure 1; As shown in Figure 2, fermentation obtains rhodotorula glutinis bio-feritlizer and is applied in the growth cycle of soybean, can reach the effect using nitrogen phosphorus composite chemical fertilizer, and comparatively nitrogen phosphorus composite chemical is fertile better at its fertilizer efficiency retentivity of plant strain growth later stage, is especially beneficial to plant footpath and slightly accumulates.
Embodiment 2 is that fermenting raw materials produces rhodotorula glutinis fertilizer application in the growth experiment of kidney bean with food and drink waste water
The acquisition of rhodotorula glutinis bacterial manure and fertilizer efficiency testing method are all with case study on implementation 1, and result of implementation is as follows:
From Fig. 4 experimental result, rhodotorula glutinis bio-feritlizer is applied in the growth cycle of kidney bean, can reach the effect using nitrogen phosphorus composite chemical fertilizer, and comparatively nitrogen phosphorus composite chemical is fertile better along with its fertilizer efficiency retentivity of prolongation of plant strain growth phase.
Following embodiment all can realize the effect of above-described embodiment 1 or embodiment 2
