Abstract
The invention discloses a watermelon fertilizer capable of sterilizing. The watermelon fertilizer is prepared from the following raw materials in parts by weight: 200-210 parts of rice straws, 20-21 parts of kaoline, 10-11 parts of urea, 6-7 parts of seashell, 4-5 parts of citric acid residues, 0.2-0.3 part of nicotinic acid, 0.5-0.6 part of monoammonium phosphate, 0.2-0.3 part of garlic oil, 15-16 parts of polyvinyl alcohol, 1-1.1 parts of tea polyphenol, 1-1.1 parts of carbon nano tubes, 1.2-1.3 parts of beta-cyclodextrine and 800-810 parts of 28% ammonia water. According to the watermelon fertilizer, amino groups are introduced to biomass charcoal prepared from the rice straws and can be chelated with heavy metals, the capability of adsorbing the heavy metals is improved, and the pollution influence of the heavy metals on soils and environments is reduced; as the carbon nano tubes are added into coated liquid, the mechanical strength of a film can be improved; the added tea polyphenol can improve the slow-release properties of the film; and in addition, as garlic oil is added, the sterilization effect can be achieved.
Description
Technical field
The present invention relates to fertilizer processing technique field, particularly relate to a kind of watermelon fertilizer being sterilized and preparation method thereof.
Background technology
Shi Ge large agricultural country of China, its crops rice straw quantity is the hugest, and according to year investigation statistics, rice straw total amount reaches about hundred million tons, and with the speed increment of annual hundred million tons.During utilizing crops rice straw, the collection of rice straw, transport and utilize during required plant equipment high cost, industrial chain is shorter, lacking the problems such as the cognitive mistaken ideas of technical support and people makes the utilization rate of crops rice straw the highest, the considerable regional burning that occurs going out of use crops rice straw, causes the wasting of resources, environmental pollution.Biomass carbon is to be formed by biological material carbonizations such as crops rice straw, wood chips.Biomass carbon has improvement result to the aspect such as soil physics, chemical property.But it is mostly to mix biomass carbon with base fertilizer to be manured into soil at present, so causes biomass carbon transporting, store, the aspect such as to use limited.Therefore, crops rice straw is prepared as biomass carbon base manure material, can have effective solve its transporting, store, use etc. the problem of aspect, have broad application prospects.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of watermelon fertilizer being sterilized and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of watermelon fertilizer being sterilized, is prepared by the raw materials in:
Rice straw 200-210, kaolin 20-21, urea 10-11, shell 6-7, citric acid waste 4-5, nicotinic acid 0.2-0.3, MAP 0.5-0.6, garlic oil 0.2-0.3, polyvinyl alcohol 15-16, Tea Polyphenols 1-1.1, CNT 1-1.1, cycloheptaamylose 1.2-1.3, the ammoniacal liquor 800-810 of 28%.
The preparation method of the described watermelon fertilizer being sterilized, comprises the following steps:
(1) by CNT and cycloheptaamylose mixed grinding 1 hour, then gained material being added appropriate deionized water ultrasonic disperse 2 hours, centrifugation, gained precipitate with deionized water washs 2-3 time, and at 75 DEG C, vacuum drying 24 hours, are ground into powder;
(2) polyvinyl alcohol is added the deionized water of 10 times, at 45 DEG C, constant temperature stirs swelling 3 hours, is then heated to 95 DEG C of stirring to polyvinyl alcohol and is completely dissolved, then adds step (1) gained material, Tea Polyphenols when temperature is down to 45 DEG C, it is sufficiently stirred for, obtains coating liquid;
(3) rice straw is pulverized, with 28% ammoniacal liquor mix, send in hydrothermal reaction kettle, at 200 DEG C, reaction 20 hours, are cooled to room temperature, and it is colourless for being washed with water to efflux, is dried to constant weight, obtains biomass carbon at 60 DEG C;
(4) shell is pulverized, mix feeding high pressure homogenizer with the water of one times homogeneous 20-25 minute;
(5) after biomass carbon, the urea respectively pulverizing of size-reduced machine, 40 mesh sieves are crossed; then the raw material that the biomass carbon after pulverizing, urea are not used with step (4) gained material and above-mentioned technique mixes; it is placed in granulating disc; rotary speed is adjusted to 30r/min; rotating disk inclination angle is 45 °; after material fully mixes; with sprayer, water is sprayed into mixing; the addition of water is the 14-15% of weight of material, to be formed after stop granulation, gained material is placed in electric drying oven with forced convection; dry to constant weight at 40 DEG C; the most uniformly spray coating liquid, be dried, to obtain final product.
The invention have the advantage that rice straw is made biomass carbon and joined in fertilizer by the present invention, the water-holding capacity of soil can be increased after applying farmland, the stability of soil agreegate, strengthen soil heat absorption capacity, and through reacting with ammoniacal liquor, biomass carbon introduces amino, amino energy and heavy metal chelating, improve the ability of its Adsorption of Heavy Metals, slow down heavy metal to soil and environment pollution effect, and the present invention adds CNT in coating liquid, the mechanical strength of film can be improved, and CNT adds, and cycloheptaamylose is modified improves CNT dispersiveness in water, the Tea Polyphenols added can introduce hydrophobic benzene radicals, improve the hydrophobicity of film, so that water absorption rate declines, improve the slow release of film, in addition, the present invention with the addition of garlic oil, the effect of sterilization can be played.
Detailed description of the invention
A kind of watermelon fertilizer being sterilized, is made up of the raw material of following weight portion (kilogram):
Rice straw 200, kaolin 20, urea 10, shell 6, citric acid waste 4, nicotinic acid 0.2, MAP 0.5, garlic oil 0.2, polyvinyl alcohol 15, Tea Polyphenols 1, CNT 1, the ammoniacal liquor 800 of cycloheptaamylose 1.2,28%.
The preparation method of the described watermelon fertilizer being sterilized, comprises the following steps:
(1) by CNT and cycloheptaamylose mixed grinding 1 hour, then gained material being added appropriate deionized water ultrasonic disperse 2 hours, centrifugation, gained precipitate with deionized water is washed 2 times, is vacuum dried 24 hours, is ground into powder at 75 DEG C;
