Technical field
The present invention relates to a kind of method of utilizing plant straw ash to produce multi-element fertilizer; be particularly useful in the straw power generation process disposal of ash and slag that produces by burning, pyrolysis, gasification etc., belong to that solid waste farming in the agriculture environmental protection field is fertile to be handled and utilize technology.
Background technology
Contain combustible elements such as C, H, S in the straw, can directly burn or by pyrolysis, gasification back indirect burning.Its calorific value of 1kg stalk is equivalent to the 0.61-0.72kg standard coal generally at 18～21MJ.China is vast in territory, and stalk resource is very abundant, calendar year 2001 eight big class staple crops stalk ultimate productions such as China's paddy, wheat, corn, beans, potato class, oil plant, cotton, sugarcane reach 59648.1 ten thousand tons, 300,470,000 tons of signature coal amounts.
It mainly is as urban residents' fuel, animal-feed or direct returning to farmland that the tradition of stalk is utilized mode.In recent years, along with popularizing of commercial energy resources such as rural economic development and farmers' income increase and coal, oil, gas, become waste or taken certain farmland mainly as the agricultural crop straw of fuel and piled up throughout the year, or on-site incineration, not only wasted ample resources, also serious environment pollution.
Straw power generation is the new way that a kind of stalk resource utilizes.At present, be widely adopted in western developed country such as the U.S., Europe, Japan etc., China has also set up the straw electric generation plant that scale does not wait in succession since the nineties, as surplus the total small power generation unit 300 in Guangdong and Guangxi two provinces, and overall apparatus capacity 800Mw.The target that proposes according to China's new forms of energy and renewable energy resources development outline will surpass 3,000,000 kw to China's biomass power generation installed capacity in 2010.
No matter be as urban residents' life fuel or be used for batch production generating, all can produce the 3-20% lime-ash in stalk pyrolysis, gasification, the combustion processes.Stalk ash contains various plants essential element nutritive element and multiple beneficial elements such as Si, Se such as P, K, Ca, Mg, Fe, Zn, Cu, studies show that in a large number, use plant ash to the significant effect of increasing production of a lot of crops, plant ash is a kind of important source of manure in China's traditional agriculture.In the stalk ash, the biological effectiveness of plant essential element and beneficial element is generally lower.The contriver had once measured straw, these two kinds of staple crops stalks of wheat and had handled down cindery pH and full potassium thereof, effective potassium, available potassium and the content of phosphorus, available phosphorus, rapid available phosphorus entirely in 300 ℃ (being equivalent to occur the naked light burning), 550 ℃ (family's port kitchen range burnings), 800 ℃ (biomass boiler burning), the results are shown in Table 1.
The pH of two kinds of different stalk ash of table 1 and phosphorus, potassium content are relatively
| The stalk classification | Temperature of combustion (℃) | Lime-ash pH | Phosphorus content (g/kg) | Potassium content (g/kg) | ||||
| Full phosphorus | Available phosphorus | Water-soluble phosphorus | Full potassium | Effective potassium | Water-soluble potassium | |||
| Wheat Straw | 300 | 10.14 | 8.1 | 2.3 | 0.7 | 27.8 | 23.1 | 20.2 |
| 550 | 10.21 | 13.4 | 6.9 | 0.3 | 91.4 | 28.0 | 22.2 | |
| 800 | 10.32 | 12.1 | 7.8 | 0.1 | 57.2 | 21.1 | 19.7 | |
| The paddy rice straw | 300 | 10.40 | 7.2 | 4.6 | 1.2 | 59.8 | 30.9 | 29.2 |
| 550 | 10.66 | 8.9 | 6.2 | 0.3 | 100.2 | 36.1 | 35.8 | |
| 800 | 9.45 | 7.7 | 6.6 | 0.1 | 63.8 | 27.0 | 26.5 | |
As can be seen from Table 1, two kinds of stalk ash all are strong basicity, and available phosphorus generally only accounts for full squama 30-70%, and effectively potassium only accounts for the 30-50% of full potassium.Obviously, when as fertilizer sources used, quite a few nutrient can not be utilized by plant absorbing.And stalk ash alkalescence is strong, and utilization ratio is lower in alkaline soils.
In addition, have in a large number studies show that, trace element is under the alkaline condition of ash content among Ca, Fe, the Zn etc., and plant availability is extremely low.
Because different sorts stalk and differing temps incendiary plant ash nutrient form difference are big, and become invalid attitude more, directly use as not adding processing, can not give full play to its fertilizer efficiency first, second may cause the crop detrimentally affect.
Chinese patent publication number CN1189481A discloses a kind of method of utilizing plant ash, excrement ash etc. to produce high potassium clacium fertilizer.It is with plant ash, excrement ash, lime excrement, industrial salt, vitriolate of tartar, Repone K, urine, makes after stirring, grind, sieving.Its shortcoming is that the fertilizer that makes becomes salinity height, alkalescence by force, and the most elements in the lime-ash (as: P, Si, Fe, Zn, Cu, Mn, Mo etc.) is in stationary state and is difficult for being absorbed by crop, especially inapplicable use in alkaline soils.
