Abstract
The present invention relates to a liquid trace element fertilizer and a preparation method thereof. The liquid trace element fertilizer is mainly composed of complexing agents (humic acid, or humic acid, citric acid and tartaric acid, or humic acid, citric acid, tartaric acid and disodium edta), trace elements (copper, zinc, manganese, ferrum, boron, molybdenum and compounds of cobalt), a stabilizing agent (urea), matrix objects, extension agents, plant growth regulators, nutrient elements of N, P, K, etc. and iodide. The liquid trace element fertilizer has the advantages of good water solubility, low preparation reaction temperature, saved irrigation water capacity, high fertilizer effect and obvious effect of increase in yield (16 to 66% of increase in yield), and has the action of drought resistance, cold resistance, alkali resistance and pest and disease damage prevention.
Description
The present invention relates to a kind of liquid fertilizer and preparation method thereof, belong to the agrochemical field.
Known liquid fertilizer has CN1042895A (89 years), it is a kind of micro-compound liquid fertilizer that is exclusively used in the mulberry leaf foliage spray, its nutrition is phosphoric acid salt, oxalate, nitrate, aluminate, muriate multielement complex compound, and the tensio-active agent of employing 0.05～5% is made extension agent.But it is water-soluble relatively poor, and owing to do not add the matrix thing, fertilizer is not strong to the sticking power of crop.CN87100319A provides a kind of plant-foliage fertilizer and preparation method thereof, it is a kind of a large amount of and micro-suspension fertilizer that contains, its liquid phase is for containing the whey of 2～4% proteolysates (amino acid), its preparation method is included under 60～80 ℃ inorganic salt is dissolved in the dispersion medium that contains fermented whey and protein hydrolystate strong solution, gained solution is sent into to make temperature drop to 20～25 ℃ refrigerating unit in 2～15 minutes at last.Adopt starch to make the matrix thing.This fertilizer has certain effect of increasing production, but temperature of reaction is higher.Nonreactive contrary (drought resisting, alkali resistant, cold-resistant) effect and prevention and elimination of disease and pests effect.
The purpose of this invention is to provide a kind of fertilizer efficiency height, good water solubility, the preparation feedback temperature is low, has degeneration-resistant effect and prevents the preparation method of the little fertilizer of full-service fluid of disease and pest effect.
For achieving the above object, the preparation method of liquid fertilizer of the present invention adopts 60-80 weight part humic acidss (salt), or adopt 60-80 weight part humates, 1,5-4,0 weight part citric acid and 1,0-2,5 weight part tartrate, or adopt 60-80 weight part humic acidss, 1,5-4,0 weight part citric acid, 1,0-2,5 weight part tartrate and 5,0-10,0 weight part disodium ethylene diamine tetraacetate to make complexing agent; Compound with copper, zinc, manganese, iron, cobalt, molybdenum and boron is made trace element, and its compound weight part respectively is 3-6 parts, 3-5 parts, 0,5-2 parts, 7-10 parts, 0,5 part, 0,5-3 parts, 8-11 parts; With 30-60 weight part urea used as stabilizers, make the matrix thing with fine polymkeric substance of starch-polypropylene or carboxymethyl starch, its weight part is 0,5-30 parts, make extension agent with dodecylbenzene sulfonate or aliphatic alcohol sulfate, its weight part is 0,05-1 part. and add an amount of N, P, K nutritive element, iodide and plant-growth regulator.
Because humic acids (salt) or humic acids (salt), citric acid, tartrate or humic acids (salt) citric acid, tartrate, these organic complexing agents of disodium ethylene diamine tetraacetate and zinc, copper, manganese, iron, cobalt, molybdenum, the compound formation multicomponent complex of boron or polynary mixed ligand binding substances, this title complex is water-soluble better, and itself and copper humate, the mixture of Zn complex and iodide is the stable disease-resistant sterilant (table 3) of a kind of chemical property, in addition, the quinonyl of humic acids (salt) title complex-polyphenol base participates in the redox processes of crop, it is the activator of oxygen, it is again the rotaring carrier of hydrogen, can promote photosynthesis, improve the synthetic of invertase activity in sugar and organic phosphorus compound, increase the crop sugar degree, improving Premeabilisation of cells presses, thereby the enhancing crop is degeneration-resistant (cold-resistant, drought resisting, alkali resistant) effect, reduce moisture transpiration, save irrigation water (table 2, table 4).Contained fine polymkeric substance of starch one polypropylene or carboxymethyl starch are good matrix things, liquid fertilizer can be attached to plant surface during use, avoid the loss of liquid fertilizer, improve fertilizer efficiency and sterilizing ability.Adopt the urea used as stabilizers, both can increase the nutrition of little fertilizer, reduce and add the non-physiologic stable material, can prevent the crystallization of liquid fertilizer again, reduce production process, reduce reactivity.Dodecylbenzene sulfonate or aliphatic alcohol sulfate are a kind of good extension agents, both can increase the spreading ability of little fertilizer in crop surface, also strengthen simultaneously immersional wetting, strengthen the absorption (table 1) of crop cell trace element and other nutritive element to crop cell.In addition, humic acids (salt), citric acid, tartrate or humic acids (salt), the complex compound of citric acid, tartrate and disodium ethylene diamine tetraacetate and trace element is a good buffer system.
By as seen above-mentioned, because liquid fertilizer of the present invention is organic acid and the micro-complex compound that forms, this complex compound not only has good water solubility, and be a cover buffer system, cooperate the mixed solution of forming with various nutrient elements such as N, P, K, S, Si, Ca, Mg and plant-growth regulator etc. again, demonstrate the synergy of mutual gain, can satisfy, regulate and stimulate crop growth, increase fertilizer efficiency.In addition, liquid fertilizer of the present invention has conversion and dissolves mercury, and the effect (table 5) of arsenic heavy metal element reduces the richness of objectionable impurities in the product amasss, and to preventing product contamination, protects environment and HUMAN HEALTH, significant.
The preparation method of liquid fertilizer of the present invention is as follows:
The first step: in container, drop into the humic acids (salt) and an amount of water of some amount, soaked into 1～3 hour, abundant stirring and dissolving, clarification filtration makes humic acids (salt) solution that density (20 ℃) is 1.0～1.2g/ml.
Second step: be that 1.0～1.2 humic acids (salt) solution injects reactor at normal temperatures and pressures with proportion, starting agitator stirs, add urea or progressively add urea, citric acid, tartrate, disodium ethylene diamine tetraacetate (giving the earlier molten solution of concentration 15% that is) makes its whole dissolvings, makes the solution that contains complexing agent and stablizer.
The 3rd step: the compound, reacting generating complex and the mixing solutions thereof that in still, add copper, zinc, boron, manganese, iron, molybdenum, cobalt successively.
The 4th step: in reactor, add plant-growth regulator, phosphorus, sylvite class again, adjust about PH to 6～8 with bicarbonate of ammonia, question response is finished, add iodide, matrix thing and extension agent, stir, dissolving is made density for (20 ℃) g/ml1.0～1.3, and PH is the liquid fertilizer that 6～8 chocolate suspends.
