Description

A kind of amino acid calcium Water soluble fertilizer and preparation method thereof
Technical field
The invention belongs to agriculture composite calcium fertilizer technology field, it is related to a kind of amino acid calcium Water soluble fertilizer and preparation method thereof.
Background technology
Calcium presented in Calcium Pectate, is the constituent of cell wall mesoglea in crop body.Calcium and protein In conjunction with, it is the important component part of cytoplasma membrane, cell membrane is constituted and reduces with cell permeability of the membrane and plays an important role, limit Cell sap extravasation processed, adjusts its acid-base value.Calcium can also promote nitrogen metabolism and carbohydrate-modifying, reduces the nitric acid in plant Salt, the organic acid in neutralization plant, there is Detoxication to the organic acid producing in metabolic process.
Calcium in plant body be with calcium ion form by xylem transport together with water to leaf, really, after the organ such as tender tip, Come into through iuntercellular, calcium could enter each cell in these organs.Because calcium ion is positively charged, in transport, it is subject to xylem The impact of negative charge group on cell wall, travelling speed is far low and moisture.Due also to the active calcium ion content is very low in soil, calcium is being planted The transport of thing body absorption is slow, and transpiration causes calcium in factors such as each crop organ distribution imbalances in addition, causes China The universal calcium deficiency of crops.
The 8th, the whole nation fertilizer communication for information held in Huhehaote for 2007 and product trading can be gone up, National Agricultural skill Art extension service center soil fertilizer technology grow tall everywhere auspicious according to introduce, the whole nation 18.51 hundred million mu arable land in, soil lack calcium, The area of the moderate-elements such as magnesium accounts for 50% about, and soil lacking boron area accounts for more than 40%, and zinc deficiency area accounts for more than 20%, lacks Manganese, ferrum, the area of copper are respectively 10%, 5%, 1%.
In China, three Main Stage of micronutrient fertiliser development experience, the first stage is middle and trace element Mineral sulfatess and oxide single dose, such as boric acid, ferrous sulfate, manganese sulfate, copper sulfate, zinc sulfate, magnesium sulfate.Due to micro- There is antagonism crop between secondary element, spray a kind of single dose and can hinder other micro- fertile absorbing；Individually spray by several times in batches Waste time and energy, fertilizer efficiency low.Second stage is complex preparation, such as the intermixture of several inorganic minerals and plant growth regulator. Being simply mixed of nutrient, due to there is antagonism crop between middle and trace element, hinders the mutual absorption of other trace element Using, and they are not to be existed with Chelating state, are not sufficiently stable, and crop interior quality are improved inconspicuous.Phase III be in, The micro- fertilizer of trace element chelated state, such as modal citric acid trace element, amino-acid trace element, the micro unit of humic acid both at home and abroad Element, EDTA, DTPA, EDDHA.These Stability of Chelates are high, avoid antagonism, be easy to utilization absorbed by crops, right Plant, people, animal nonhazardouss, safe and reliable.Chelate degree of dissociation very little although they in aqueous metal ion activity fall Low, but these ions are combined with chelating agen and so that its solubility is greatly increased, and be easily absorbed by plants, antagonism will not occur. Because trace element ion is secured by complex, in the aqueous solution of various trace element, will not occur between different ions Interact, can coexist in the solution, and solution has stronger stability.
Crop is particularly easy to the reason absorb and is because metallo-chelate quite stable to metallo-chelate.In multidentate ligand After certain coordination atom is combined with central metal atom, the distance of remaining coordination atom and central atom reduces, they with The probability that heart atom combines just increases.If wherein have one coordinate bond destroy, due in multidentate ligand other coordination atoms still with Heart atomistic binding so that destroyed coordinate bond is easier to recover.The more, part is available for coordination atom in multidentate ligand Coordination atom just the more, forms chela ring just the more, and just the more, part takes off the coordinate bond that same part and central atom are formed Just less from the chance of central atom, chelate is just more stable.Therefore, crop is particularly easy to absorb metallo-chelate.
The stable factor of metallo-chelate is to be determined by the size and number of chelate ring.In most chelates, with The chelate of five-membered ring and hexatomic ring is the most stable.The bond angle of both rings is 108 ° and 120 °.As Ca2+With EDTA homologue (- OOCCH2)2N(CH2)nN(CH2COO-) stability constant of the chelate of 2 formation reduces with the increase of n value.This is because five yuan , closer to the angle (109 ° 28 ') of the sp3 hybrid orbital of Ca, tension force is little, and ring is stable for the bond angle (108 °) of ring.Chelate ring number More, its stability is stronger.
Although this several years crops calcium supplementing products are a lot, great majority are calcium chloride (CaCl2), calcium oxide (CaO2), cross phosphorus Sour calcium (CaH2PO4) and pin acid calcium (CaNO3) etc. non-chelated state single-dose product, absorbed slow using ensuing crop, effect is poor.And it is northern In square basic soil, water quality is in alkalescence, that is, contain hydroxyl, divalent calcium ions (Ca2+) easily form hydrogen-oxygen with hydroxyl (OH-) Change calcium Ca (OH)2, and the latter is slightly soluble in water.Crop can utilize carbon dioxide (CO under illumination condition2) carry out photosynthesis, empty Substantial amounts of carbon dioxide (CO is contained in gas2), calcium hydroxide (Ca (OH)2) can be with carbon dioxide (CO2) carry out chemical reaction generation Calcium Carbonate (CaCO3), and Calcium Carbonate (CaCO3) water insoluble, crop cannot absorb at all.So, in northern alkaline soil, Apply non-chelated state calcareous fertilisers and easily produce white dot, i.e. Calcium Carbonate (CaCO in fruit face3) crop can not absorb.In addition, at present Northern China Fructus Mali pumilae, pears, Fructus Vitis viniferae, Fructus actinidiae chinensiss, Fructus Persicae, Punica granatum L. etc. all promote bagging technique, and general fruit bagging calcium deficiency phenomenon is more commonly.
