Economy class crop provides a kind of new fertilizer selection, can significantly improve the yield of commercial crops such as vegetables, fruit tree and quality, simultaneously
The present invention for the problem that the residence time is too long in the environment for certain chelating agents, to environment have it is certain endanger, use is leading in the world
Novel I DHA (iminodisuccinic acid) chelating agent, IDHA can be biodegradable completely, both can guarantee the stabilization of nutrient
Property, improve absorption rate, moreover it is possible to reduce the pollution to soil and environment.
Specific embodiment
The technical scheme of the present invention will be explained in further detail With reference to embodiment, and the present invention is previously mentioned
Ratio, " part ", if being subject to weight without particularly marking.
The present invention relates to a kind of polynary novel alga water soluble fertilizer, component and mass parts are as follows: marine algae extract 10-25
Part, 0-100 parts of urea, 10-50 parts of ammonium dihydrogen phosphate, 10-140 parts of potassium nitrate, chelating calcium 1-80 parts, 1-30 parts of chelated magnesium, chela
Iron 1-2 parts is closed, 1-2 parts of chelated copper, 1-2 parts of chelated zinc, 1-2 parts of Chelated Manganese, polymerize boric acid 1-2 parts, silica (AC) 0.5-3
Part.Polynary novel alga water soluble fertilizer of the invention adds high activity marine algae extract, and is added to a large amount of members of high-quality
Microelement in element and IDHA Chelating state, can promote crop growth, improve the yield and quality, moreover it is possible to it is degeneration-resistant to improve crop
Property, mitigate external environment stress and pest and disease damage infects, moreover it is possible to each nutrient stability and utilization rate are improved, it is high-quality and efficient, while energy
Soil is improved, it is environmentally friendly.
Said components are all made of domestic and international high-quality feedstocks, such as potassium nitrate using the potassium nitrate of Chile's SQM import, phosphoric acid
Ammonium dihydrogen uses ShenFang,SiChuan food grade phosphoric acid ammonium dihydrogen, and chelating element is using microelement in Poland's IDHA Chelating state, polymerization
Boric acid is using the polymerization boric acid of Chile SQM production, and silica is using Taiwan meteorology superfine silicon dioxide anticaking agent.
Above-mentioned urea, ammonium dihydrogen phosphate, potassium nitrate, are all made of technical grade or food-grade high-quality feedstocks, can basis
Different proportion is each adapted for high nitrogen, high phosphorus, high potassium or balanced formula, high nitrogen formula (such as nitrogen phosphoris and potassium fertilizer ratio is 30:10:10)
It is suitble to the application of crop vegetative growth stage, meets the nutrient demand and morphogenesis of crop nutrient growth.High phosphorus formula (such as nitrogen
Phosphorus potassium proportion is 10:30:10) it is suitble to crops seedling stage application, it may advantageously facilitate root system development, be later period nutrient absorption and nutrient product
It is tired to lay a solid foundation.High potassium formula (such as nitrogen phosphoris and potassium fertilizer ratio is 10:10:30) is suitble to apply when crop later period Fruit, can be with
Accelerate Photosynthate trasport, promote Fruit, improve fruit sweetness, improves fruit quality, improve the Commodity Competition of fruit.
Equilibrium formula (such as nitrogen phosphoris and potassium fertilizer ratio is 17:17:17) can be in any period application of crop, cooperation high nitrogen, high phosphorus or high potassium
Formula provides balanced nutritious, guarantee crop robust growth according to crop growth conditions for entire growth period.
Above-mentioned chelating calcium, chelated magnesium, can be calcium according to the discrepancy adjustment of method of administration: magnesium ratio be 2-5:1.It is preferred that
, adjust calcium in foliage-spray: magnesium ratio is 2.5:1, meets crop foliage dressing to the best demand of calcium and magnesium ratio；It is rushing
Apply or when trickle irrigation is applied adjusts calcium: magnesium ratio is 4:1, meets the fertile assimilation ratio to calcium magnesium element of crop root.
Above-mentioned chelating calcium, chelated magnesium, chelated iron, chelated copper, chelated zinc, Chelated Manganese are all made of IDHA (imino-diacetic amber
Acid) chelating technology, wherein calcium content is 10% in chelating calcium, content of magnesium is 15% in chelated magnesium, and iron content is in chelated iron
13%, copper content is 15% in chelated copper, and Zn content is 15% in chelated zinc, and manganese content is 13% in Chelated Manganese.IDHA cooperation
Based compound can generate a kind of octahedra three-dimensional knot with divalent or trivalent metal ion under the reaction conditions such as certain temperature and pressure
Structure, and by unique micropore granulating technique, reach character stabilization, good water solubility, the characteristic without agglomeration, easy mixture.It is different
In common chelating agents, IDHA (iminodisuccinic acid) can be biodegradable completely, and the metal ions such as Ca, Mg and Fe copper zinc-manganese are made
After object is absorbed and utilized, IDHA itself can be decomposed into CO in the natural environment2And H2O, it is environmentally safe harmless.
The marine algae extract added in the present invention is handled using cold-adapted enzyme biodegrading process, and the seaweed after air-drying is put into drop
In Xie Chi, adds water to and cover seaweed upper surface, the biology drop such as addition algin enzyme, carrageenase, agarase or mannase
Enzyme material is solved, and is properly added citric acid or potassium hydroxide to adjust solution ph in degraded pond, is degraded 1-3 days, then mistake
Filter, concentration purification add potassium fulvate crystallization and are precipitated, obtain marine algae extract after drying and crushing.This method and addition sulfuric acid
The high temperature high pressure drop solution such as hydrochloric acid is compared, and marine alga natural active constituent is greatly remained, and active skull cap components include 3-8% seaweed
Polysaccharide and oligosaccharide, 0.1-2% phenols poly-compounds, 2-15mg/kg glycine betaine, 12-150mg/kg mannitol, 25-
The functional components such as the 200mg/kg basic element of cell division, 4-50mg/kg auxin, 0.03-17.8mg/kg gibberellin have nutrition complete
It improves crop resistance, improve the advantages that soil micro-ecosystem and natural nuisance-free, while some steroids or biological modulated can be removed from face
Save the use of agent.
The basic element of cell division rich in the marine algae extract added in the present invention, auxin, gibberellin, glycine betaine and
Mannitol etc. can promote the hormonal substance of crop growth, these substances need enough in promoting process of crop growth
Nutrient is as material base, for amino acid, protein, nucleic acid, carbohydrate needed for synthesizing crop growth
Deng basic organic substance, nutrient includes large amount of elements and medium and trace elements, and a great number of elements added in the present invention is complete
Water-soluble product can be entered in crop body with the soil liquid by active absorption or Passive intake in crop root microenvironment,
Participate in assimilation physiological action.And the metallic elements such as middle microelement calcium and magnesium Fe, Mn, Cu zinc are very easy to and soil micelle in the soil
In conjunction with, lose validity, utilization rate is very low, and accumulate arrive certain amount, be easy to cause metal ion poison or antagonism its
Its element absorption.Middle microelement after being chelated using IDHA can keep nutritional activities in the soil, will not be by adsorption by soil
It is fixed, under the promotion of the hormonal substances such as the basic element of cell division, auxin, gibberellin for containing in marine algae extract, quickly into
Enter in crop body, participates in the physiological and biochemical procedures such as photosynthetic, breathing, transpiration.
In order to make the water-soluble fertilizer of preparation keep good mobility and stability, titanium dioxide also added in the present invention
Silicon (AC) is used as anticaking agent, and fineness fully ensures that each material will not stick together agglomeration up to 5000 mesh, while not influencing to produce again
Product are water-soluble.
