Description
The present invention relates to the little fertilizer and the preparation technology thereof of amino acids metal title complex.
Little fertilizer is the indispensable nutritive element of crop growth, when soil lacks trace element, will cause crop failure, and diseases and insect pests resistance descends, and solid quality reduces.Since the eighties, raising and long-term application macroelement fertilizer along with China's crop yield level cause various trace elements to wane.The area of China's soil shortage trace element has reached several hundred million mus at present, and therefore the development of little fertilizer is subject to people's attention with application.But up to now, domestic existing trace element fertilizer mostly is the mixture of inorganic salt, for example zinc sulfate, manganous sulfate, rare earth nitrate etc., because little fertile mixing when using of plurality of inorganic salt, antagonistic action of Chan Shenging and crop thereof often cause the action effect decline of the little fertilizer of inorganic states to reasons such as the specific absorption of the little fertilizer of inorganic states are low each other, this type of little fertilizer also exists easily and is fixed in addition, solubleness is little, shortcomings such as biochemical function difference, thereby fertilizer efficiency is not good.
In recent years, trace element fertilizer both domestic and external just develops towards the direction of the little fertilizer of water-soluble organic complex compound, and China makes encouraging progress in the research in this field.Chinese patent " synthetic method of mixed amino acid rare earth compound " (application number 8910583.2), introduce a kind of animal and plant albumen that utilizes and be raw material, obtain the mixed amino aqueous acid through hydrolysis, obtain corresponding amino acid with rare earth with rare-earth mineral or rare earth compound reaction again, product is as agricultural chemicals, as disinfectant use in agriculture.The Chinese patent of application number 90105804.1 has been set forth " formula of metal complex in agricultural mixed amino acid ", for example: 30～50% manganese amino acids among the prescription A, 20～30% amino-acid zincs, 20～30% amino acid copper and 10～20% amino are joined the calcium collocation, as disinfectant use in agriculture; 55～75% amino acid iron among the prescription B, 10～20% amino acid-magnesium chelates, 20～30% amino acid light rare earthss are formed disinfectant use in agriculture, can be used for cotton and prevent and treat verticillium and control fruit tree yellowing disease; Among the prescription C with 50～70% amino acid calciums, 20～30% amino acid copper, 10～20% potassium amino acids collocation can be used for preventing and treating cotton seedling blight and anthrax; Among the prescription D, with 40～60% amino-acid zincs, 30～40% manganese amino acids, 10～20% amino acid light rare earthss are formed disinfectant use in agriculture, can be used for preventing and treating citrus gummosis etc.; In prescription E, with 50～70% amino acid copper, 20～30% amino acid calciums and the collocation of 10～20% amino acid light rare earthss are used for the short length of flowers, degeneration-resistant and diseases prevention.Another part Chinese patent " a kind of organic amino acid trace-fertilizer and production technique " (application number 92106896.4), a kind of waste that utilizes slaughtered animals is provided, through sulfuric acid or hydrochloric acid hydrolysis, further degrease, removal of impurities obtain kilnitamin, add boron, zinc, iron, manganese slag and rare earth again, make the method and the product of organic amino acid trace-fertilizer through reaction, every mu of fertilising 0.5kg sprays after diluting 200 times, can be used for the volume increase of paddy rice and cotton.
The prescription of above-mentioned organic amino acid trace-fertilizer and production technique have following weak point:
1, amino acid whose extraction needs to obtain through hydrochloric acid or sulphuric acid hydrolysis from the Keratin sulfate of animal and plant, and starting material source limitation is big; 2, mishmetal, trace element (zinc, iron, manganese) are all finished under same reaction conditions with amino acid whose complex reaction.In fact under identical conditions, can not both have been contained the amino acid coordination compound that mixes rare earth simultaneously, there is bigger difference in the amino acid coordination compound that contains trace element again because mishmetal, trace element (zinc, iron, manganese) and amino acid carry out the acidity condition of complex reaction.The method that is provided according to 92106896.4 patents, can only obtain the amino acid coordination compound of mishmetal, the inorganic salt of boron, zinc, iron, manganese and amino acid whose mixture, or zinc, iron, the amino acid coordination compound of manganese, inorganic salt, boron salt and the amino acid whose mixture of mishmetal; 3, the preparation of organic amino acid trace-fertilizer is all carried out in sulfuric acid or hydrochloric acid medium, and used metal-salt is vitriol or muriate.Because rare earth sulfate is water insoluble, in the presence of sulfate radical, boron salt also precipitates, so in sulfuric acid or sulfate medium, when in the solution of kilnitamin, adding boron, zinc, iron, manganese and rare-earth salts, can produce a large amount of rare earth sulfates and boron salt precipitation, and cause amino acid whose precipitation loss, and can not obtain water miscible mishmetal amino acid coordination compound and micro-amino acid coordination compound.89105853.2 the mixed amino acid solution that number patent and No. 92106896.4 patent utilization sulphuric acid hydrolysis obtain is actually irrealizable by adding the method that mishmetal or boron, zinc, iron, manganese slag and mishmetal prepare water miscible respective metal amino acid coordination compound.Though the amino acid solution that utilizes hydrochloric acid hydrolysis to obtain, can prepare corresponding mishmetal amino acid coordination compound, or the amino acid coordination compound of trace element, but, long-term application easily causes hardening of soil because containing the fertilizer of a large amount of chlorions, and some crop is to prohibit chlorine crop (for example tobacco, sweet potato etc.), does not also advocate so contain the fertilizer of a large amount of chlorions; 4, contained micro-kind is few in little fertilizer, function singleness, and narrow application range is increased production not remarkable.89105853.2 number patent has only prepared the amino acid coordination compound of mishmetal; 90105804.1 though patent has obtained the amino acid coordination compound of mixed light rare earth, manganese, zinc, copper, iron, calcium, potassium, but in five little fertilizer formulas being developed, only contain the amino acid coordination compound of three kinds or four kinds elements in each prescription, and can not realize the mutual combination of multiple metallic element amino acid coordination compound.
