Abstract
The invention provides a process for producing a plant root growth regulator by cow dropping, belongs to the technical field of fertilizer processing and application, and aims to solve the technical problems that: the production for maturing cow dropping by bacteria needs long time and more areas, the fertilizer has small effect to plant root growth, the utilization rates of nitrogen, phosphor and kalium in the fertilizer are low, more than 50 percent of nutrient flows into a river along with rainwater to form eutrophication, the water body is polluted, and coal and phosphate ore are wasted. The technical scheme adopted by the process comprises the following steps: uniformly mixing the cow dropping and ammonium sulfite; adding nitrogen to adjust the PH value of the mixture; and allowing a sulfonation reaction at a certain temperature to change the physicochemical property of lignin compounds in the mixture. The plant root growth regulator promotes plant root growth when being added into a fertilizer. The plant root growth regulator has the main usage that: when being used in the fertilizer, ammonium lignosulfonate promotes the plant root growth, and improves the utilization rate of nitrogen, phosphor and kalium through a developed root system, so that the fertilizing usage is reduced, the coal and phosphate ore resources are saved, pollution of nitrogen, phosphor and kalium which are lost along with water to pollute the water body environment is reduced, and the additional value of the cow dropping is improved.
Description
Affiliated technical field:
Present technique belongs to agricultural fertilizer processing and application, to the Sulphonation of Lignin in cow dung, changes its physicochemical property with ammonium sulfite, and it is added in fertilizer, and plant root growth is played a driving role.
Background technology:
At present, inorganic fertilizer ammonia-nitrogen utilization rate 30% left and right, market, phosphorus utilization 15～20%, flow into the river with water more than 50% and form and pollute, waste coal and phosphate rock resource.Cow dung on market is all to add in cow dung with fine bacterium evenly to mix, and adjusts its carbon, nitrogen ratio and moisture, and with ripe rotten explained hereafter organic manure, take 25～30 days ripe rotten winter time, takes 15～25 days summer, and the time cycle is long, efficient is low, site area is large; The fertilizer of producing has improving effect to soil, but little to the plant root growth effect, and is little to improving nitrogen, phosphorus, the effect of potassium availability.
To Sulphonation of Lignin in cow dung, change its physicochemical property with ammonium sulfite, add in fertilizer, plant root growth there is obvious facilitation, the flourishing rate of capillary root improves more than 50%, and the reaction time needs only 3 hours, and floor space is 1/20th of the ripe rotten technique of same output.The lignin ammonium sulphonate as plant root growth regulator of separate dissolved in water after reaction, solid is made organic manure, wherein also is rich in ammonium lignosulphonate, and this fertilizer has facilitation to plant root growth.Flourishing root system of plant raising nitrogen, phosphorus, potassium availability are obvious.
Summary of the invention:
Cow dung is evenly mixed with ammonium sulfite, adds nitrogen or MgO to adjust its pH value, and lignin and ammonium sulfite sulfonating reaction at a certain temperature in cow dung generates the soluble lignin ichthyodin.Change the physicochemical property of lignin in cow dung, add in fertilizer plant root growth is played a driving role.Flourishing root system of plant can improve the availability of Nitrogen, phosphorus, potassium.Reduce the fertilising consumption, reduce because heavy dressing outflows with water the negative nutrient laden that water body environment is formed, reduce the pollution of water environment; Save coal, phosphate rock resource; Improve the cow dung added value.
Description of drawings:
Accompanying drawing is production technological process of the present invention
Embodiment:
ammonium sulfite with 100% is to over dry cow dung addition 20%, nitrogen (urea, carbonic hydroammonium, ammoniacal liquor) add 4% (or MgO 4%) in pure ammonia, liquor ratio 1: 4, add ammonium sulfite according to the cubage that how much reaches ammonium sulfite of reactor dress over dry cow dung, the amount of nitrogen (or MgO), add and pass into steam after mixing in reactor, rise to 0.7MPa pressure and pressurize in 30min, 140～150 ℃ of lower isothermal reactions of temperature are after 3 hours, material after hybrid reaction is passed through solid-liquid separating machine again, the ammonium lignosulphonate that is dissolved in the water is separated, liquid is concentrated to 40～42% concentration through evaporator device again, make the ammonium lignosulphonate that is dissolved in the water be processed as solid powdery through atomization drying equipment again, be packaged into every bag of 25KG product with containing inner membrane bag, be ammonium lignosulphonate-plant root growth conditioner.The isolated cow dung that there is no the ripe rotten technique of cow dung replacement of dissolving of seperator goes the fertilizer Workshop Production to be rich in the fertilizer of ammonium lignosulphonate.Promote the growth of root system of plant, flourishing root system of plant improves the availability of Nitrogen, phosphorus, potassium, reduces the agricultural fertilizer consumption, reduces because heavy dressing outflows with water the negative nutrient laden of the water body that water body environment is formed, and reduces the pollution of water body environment.
Claims (1)
1. the method for a producing plant root growth regulator by cow dropping is characterized in that cow dung, ammonium sulfite and MgO mix sulfonating reaction production ammonium lignosulphonate with (i) cow dung, ammonium sulfite and nitrogen or (ii); Wherein, nitrogen is urea, carbonic hydroammonium or ammoniacal liquor; Urea, carbonic hydroammonium, ammoniacal liquor or MgO guarantee to react and carry out under neutrallty condition as the pH value conditioning agent of sulfonating reaction.
