Abstract
The invention relates to a controlled-release fertilizer special for rice and produced by monosodium glutamate mother solution, belonging to the fertilizer special for rice. Bacillus licheniformis is used for fermenting the monosodium glutamate mother to produce gamma-PGA (polyglutamic acid), NH4<+>, and P and K with certain proportion are added as required by rice, therefore, the controlled-release fertilizer special for rice is produced. The controlled-release fertilizer special for rice has the effects that as the ratio of nitrogen, phosphorus and potassium is reasonable, the amount of the fertilizer can be reasonably controlled to be applied according to the yield of rice and the nutrients can be reasonably supplied in balance according to the requirements of the rice for the fertilizer in different growth periods, the rice can grow vigorously, the percentage of earbearing tiller is improved, the spikelet number per panicle is increased, the maturing rate is improved, and the yield is increased; besides, the production cost is reduced, the fertilizer is convenient to use and can achieve the effects of increasing yield and income and synergism, therefore, the controlled-release fertilizer is the ideal fertilizer for rice.
Description
Technical field
The invention belongs to a kind of paddy rice-dedicated fertilizer, refer in particular to the paddy rice-dedicated fertilizer that utilizes sodium glutamate mother liquid to produce.
Background technology
China is glutamate production big country, and annual production occupies first of the world, and 1 ton of monosodium glutamate of every production, discharge 20～25 tons of high concentrated organic waste liquids, i.e. sodium glutamate mother liquids.Sodium glutamate mother liquid refer to Gourmet Powder Factory produce in monosodium glutamate process through etc. the waste liquid that discharges after electric separation and Extraction L-glutamic acid.When domestic Gourmet Powder Factory extracts L-glutamic acid from fermented liquid, it is generally not first separating thallus, directly from the fermented liquid that contains thalline and protein and enriched material thereof, extract L-glutamic acid, and domestic increasing monosodium glutamate enterprise gradually developing trend in etc. electric mother liquor no longer reclaim residual L-glutamic acid through ion exchange column, but directly fully utilize and wastewater treatment after qualified discharge, to reduce production costs, improve comprehensive benefit.Therefore, Deng containing a large amount of protein and other nutritive ingredients in electric mother liquor, it is reported, L-glutamic acid residual in mother liquor is about 1.2%～1.5%, have even up to 2%, account for 20%～25% of fermentation liquid Glutamic Acid, a large amount of thalline that wherein contain are quality protein sources, and crude protein content accounts for 70%～80%.At present Gourmet Powder Factory adopts concentrated, hydrolysis and neutralization, granulation to make composite fertilizer to sodium glutamate mother liquid.
Three elements nitrogen, phosphorus, the potassium demand of different crops to fertilizer is different, use nitrogen, phosphorus, the potassium of high-content if stereotyped, do not apply fertilizers scientifically, the rational application of fertilizer, to make plant growth bad, and increase production cost, consume the energy, cause the pollution of environment, do not reach volume increase, increase income, the object of synergy, do not utilize sodium glutamate mother liquid to produce the paddy rice-dedicated fertilizer with slow releasing function at present.
Summary of the invention
The invention provides and a kind ofly utilize sodium glutamate mother liquid to produce to there is the paddy rice-dedicated fertilizer of slow releasing function, the problem that can not be suitable for paddy rice use completely existing when solving with sodium glutamate mother liquid production composite fertilizer.
The technical scheme that the present invention takes is to be obtained by following method:
(1), utilize activated lichem bacillus strain to carry out fermentation culture, in fermentation culture process, first slant strains is carried out to liquid seeds cultivation, then in fermention medium, carries out fermentation culture with 10% inoculum size; Culture condition, shaking culture: 150～250r/min under pH7.0～7.4,30～40 ℃ of temperature, aerobic conditions, in fermenting process, stream adds glucose and sodium glutamate mother liquid, makes the concentration of glucose and L-glutamic acid all maintain 10-15g/L, and fermentation time is 48～72h;
(2), the sodium glutamate mother liquid that contains γ-PGA in step () being concentrated into dry matter content is 40%;
(3), the sodium glutamate mother liquid concentrated solution pH value that contains γ-PGA that obtains of set-up procedure (two), add wherein 1%～3% bicarbonate of ammonia, making its pH value is 6.2～6.4;
(4), in step (three), add containing NH
4 +, P, K composition, make N account for whole dry-matter total masses 18～22%, P
2o
5account for whole dry-matter total masses 4～6%, K
2o accounts for 8～12% of whole dry-matter total masses, puddles evenly;
(5) spray granulating, dries, and screening is air-dry, cooling, packing warehouse-in.
The present invention, according to the nutrient uptake feature of the regulation of fertilizer requirement of paddy rice and different growing, utilizes sodium glutamate mother liquid to produce the paddy rice-dedicated fertilizer with slow releasing function.The present invention selects in the lichen bacillus ferments monosodium glutamate waste liquid generation fermented liquid is rich in gamma-polyglutamic acid-, then through concentrated, neutralization, adds NH
4+, P, K granulation make compoiste fertilizer, this fertilizer contains amino acid, residual sugar, N, K, P and the required trace element of multiple paddy rice, can be for Rice Cropping, to improve rice yield.
Advantage of the present invention is due to its nitrogen, phosphorus, potassium reasonable ratio, and can by produce rice yield rationally control using of total amount and according to paddy rice different growing to the demand of fertilizer carry out rationally, balance supply nutrient, make paddy rice steady raw strong long, improve the percentage of earbearing tiller, increase the real grain of every fringe number, setting percentage, thereby improve output.And it has reduced production cost, it is also convenient to use, can reach volume increase, increase income, the effect of synergy, and be a kind of desirable paddy rice-dedicated fertilizer.Therefore this patent relates to the compound fertilizer dedicated to paddy with slow releasing function of production, has improved the original kind of factory's fertilizer single, has improved value-added content of product, thereby realizes significant economic benefit.
