Abstract
The invention discloses a fulvic acid potassium chelating fertilizer, belonging to the technical field of agricultural fertilizers. The fulvic acid potassium chelating fertilizer comprises the following raw materials in parts by weight: 18 parts of chelating agent, 18 parts of heavy calcium carbonate, 20 parts of urea, 12 parts of ammonium sulfate and 8 parts of ammonium nitrate, wherein the chelating agent is made from copper sulfate, ferrous sulphate, zinc sulfate, manganese sulfate, boric acid, fulvic acid potassium, urea, ethylene diamine tetraacetic acid (EDTA) and the like. Strong complexing ability and rich nutrient substances of fulvic acid potassium are utilized in the invention by a scientific and simple method. The fulvic acid potassium chelating fertilizer has high fertilizer efficiency, meets growth need of crops, improves utilization ratio of the fertilizer, and reduces environmental pollution.
Description
Technical field
The present invention relates to a kind of chelating fertilizer, be specifically related to a kind of potassium fulvate chelating fertilizer, belong to the agricultural fertilizer technical field.
Background technology
Crop growthing development needs macroelement and middle trace element, and this is proved by theory and practice, will be big or middle, trace element makes compound (mixing) fertilizer and uses, its function and fertilizer efficiency all are better than straight fertilizer and some only contain compound (mixing) fertilizer of macroelement, and this is verified in agriculture production.Because the influence of soil physics and chemical environment, closely questioning between some nutritive element resists effect, causes nutritive element not absorbed fully by crop.Part runs off, part is fixedly become by metal ion can be with the exchange state material, and part is adsorbed by soil colloid, has influenced effective utilization of fertilizer component to a great extent.A lot of fertilizer technologies have all been done certain effort on addressing these problems, obtained certain progress, still, all do not jump out the scope that concerns between the change element, have both influenced the growth of farm crop, cause the significant wastage of fertilizer again.
Potassium fulvate (BSFA) is to use modern biotechnology, is raw material with plant slag body, through biological fermentation, successfully produces class coalification xanthohumic acid material---high reactivity BSFA type biochemical fulvic acid potassium becomes the best substitute of coalification xanthohumic acid.The physiological function that studies confirm that potassium fulvate mainly contains: the food chain that scientific combination is new, overall balance plant demand; The short long factor with the unknown of high biological activity function; Complex ability is strong, improves the absorption and the running of minimum plant element; Deflocculate, tool buffering, solubility property is good, and is strong with metal ion interaction ability; Remarkable function with cold-resistant drought resisting; Molecular weight is the most basic physicochemical property of biochemical fulvic acid potassium for a short time.Utilization strong complex ability of potassium fulvate and the nutritive substance development of new chelating fertilizer that is rich in thereof can solve the deficiencies in the prior art, for agriculture production provides high-quality, efficient, cheap fertilizer.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of potassium fulvate chelating fertilizer is provided, this chelating fertilizer has utilized the strong complex ability of potassium fulvate and has been rich in nutritive substance, make by science, easy method, the fertilizer efficiency height, can satisfy the crop growth needs, improve utilization rate of fertilizer simultaneously, reduce environmental pollution.
Technical scheme of the present invention is: a kind of potassium fulvate chelating fertilizer, it is characterized in that, and make sequestrant 18, coarse whiting 18, urea 20, ammonium sulfate 12 and ammonium nitrate 8 by the raw material of following weight parts.
Described chelating fertilizer can be prepared according to two following methods:
1, takes by weighing material by weight: sequestrant 18, coarse whiting 18, urea 20, ammonium sulfate 12, ammonium nitrate 8; Material is mixed with physical method, and pack gets finished product.
2, take by weighing material by weight: sequestrant 18, coarse whiting 18, urea 20, ammonium sulfate 12, ammonium nitrate 8; Various raw materials add 50～75% water after mixing, and make slip, make chelating fertilizer with mortar jetting method, get finished product.
Described sequestrant is made by the raw material of following weight parts, copper sulfate 50, ferrous sulfate 50, zinc sulfate 250, manganous sulfate 200, magnesium chloride 5, urea 25, potassium fulvate 120, EDTA 2 and boric acid 0.8.
The preparation method of described sequestrant is: above-mentioned raw materials is joined in the reactor, add raw material total mass 2-5 water doubly, stir, be heated to 80～95 ℃, reacted 4～6 hours, carry out centrifugation afterwards, oven dry, product contains free water content 2～6%, pH value 6～8, outward appearance is light brown powder to brown, and granularity is 60～80 orders.
Compared with the prior art excellent results of the present invention is as follows:
1. fertilizer nutrient composition content height: both contained macroelement (N, P, K), and contained middle trace element (Ca, Mg, S, B, Mn, Cu, Fe, Zn, Cl) again, and formed multielement compound fertilizer.The product total nutrient is greater than 36%.
2. with low cost: the raw material that this fertilizer adopts is the domestic raw material that is easy to get, and cost is low, and production technique is simple.
3. utilization rate of fertilizer height: this fertilizer adopts chelating technology, in, trace element is the chelating form, is dissolved in water, absorbed the utilization rate of fertilizer height by crop with water.
4. pollution-free: this fertilizer dissolubility is good, cooperates spray, drip irrigation equipment, realizes water and fertilizer coupling, the nutrient supply of fertilizer and crop alimentary demand match, and the utilization rate of fertilizer height is residual few, having reduced nutrient to phreatic leaching loss, kept soil from packing together and secondary salinization, is free of contamination environment-friendly fertilizer.
5. wide adaptability: this fertilizer is adapted to various vegetables, fruit tree and field crop, can be used as spray, drip irrigation fertilizer, foliage fertilizer, dashes fertilising and substrate culture fertilizer.
Below further specify beneficial effect of the present invention by field test.
1. through for many years field test, chelating fertilizer of the present invention can significantly improve product and the quality of farm crop, result such as table 1:
Test-results between table 1 potassium fulvate chelating fertilizes the soil
Annotate: three parallel sampleses are adopted in each test, the fertilizer that check sample is selected for use with locality fertilising custom; Fertilizing method is all decided according to the fertilising custom of locality.
In sum, chelating fertilizer of the present invention can significantly improve fertilizer utilization ratio, reduces the chemical fertilizer environmental pollution, improves the quality of product.
2. use the summary of potassium fulvate chelating fertilizer more, see Table 2.
How table 2 uses the summary of potassium fulvate chelating fertilizer
