Description

A kind of special compound foliage fertilizer for liquid type corn
One, technical field
The present invention relates to a kind of chemical fertilizer, particularly polyelement composite fertilizer exactly, is a kind of special compound foliage fertilizer for liquid type corn.
Two, background technology
Corn is one of most important food crop in the world.Corn all one's life to experience the seeding stage, tri-leaf period, jointing stage, typhon mouth phase, heading stage, flowering period and ripening stage, be a kind of short high-yield crop of temperature, happiness light, breeding time of liking.Because tall and big, the well developed root system of milpa, absorption ability of nutrient are strong, the various nutrients that therefore need are many.Fertilising is that corn obtains high yield, improves the corn quality, one of important measures that reduce production costs.Generally, the nitrogen element of corn absorption in the time of infertility is maximum, and potassium element takes second place, and phosphoric is minimum.Be above-mentioned three kinds of periods that element absorption is fastest, absorbed dose is maximum jointing stage to heading stage.In addition, zinc can affect the synthetic of former growth hormone in the indolylacetic acid in the Corn etc., and iron directly affects the content of corn Determination of Chlorophyll.Corn is medium anti-boron crop, and is lower to the demand of manganese, molybdenum.Therefore on the basis of rationally having executed base manure, in jointing stage, typhon mouth phase, heading stage, flowering period each spray liquid build corn composite foliage fertilizer 1 time can Effective Raise product production and quality.Yet may chemical reaction occur between big or middle, the micronutrient element and cause nutrient availability to reduce, the residence time of foliar nutrient on the crop blade face directly affects the utilization ratio of nutrient simultaneously.Therefore, need the centering trace element to carry out chelating, will carry out wettability to solution and process.
The bright body of one plant contains the moisture of 65-95% and the dry-matter of 5-35%.Dry-matter mainly is comprised of carbon, hydrogen, oxygen, nitrogen and ash element, and they account for 45%, 42%, 6.5%, 1.5% and 5.0% of dry weight successively in plant materials.In 5.0% ash content, contain tens kinds of elements, but wherein only some is that plant is necessary and useful.So-called plant essential nutrient element is exactly indispensable element in the plant growth and development process.If lacked, just plant can not be finished the breeding cycle of being born at last seed of new generation by seed germination through growing.Except essential nutritive element, also have the not all higher plant of some elements institute essential, but they are essential to certain plants; Or be conducive to the growth of certain plants; Perhaps can alleviate the toxic action of other elements; Or can be in lower function of some specificity etc.These elements are called as beneficial element.The plant essential nutrient element of having determined at present has 16, i.e. carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulphur (S), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo), boron (B), chlorine (Cl).And be divided into macroelement, comprise carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium; Moderate-element comprises calcium, magnesium, sulphur; Trace element comprises iron, manganese, copper, zinc, molybdenum, boron, chlorine.Common are beneficial unit have: sodium (Na), silicon (Si), cobalt (Co), nickel (Ni), selenium (Se), alum (V) and iodine (I) etc.
Three, summary of the invention
The present invention is intended to provide a kind of pancebrin build composite foliage fertilizer for corn, so-called full nutrition comprises needed a large amount of, the middle amounts of corn growth and micronutrient element, and technical problem to be solved is the proportionlity of various nutrient elements and the consistency in solution thereof.
The alleged macronutrient of the present invention refers to nitrogen, phosphorus and potassium, is selected from urea, potassium primary phosphate and saltpetre or vitriolate of tartar, and its content is respectively with N and P 2O 5And K 2The O meter; The alleged middle amount nutritive element of the present invention refers to magnesium and sulphur, is selected from sal epsom, zinc sulfate and manganous sulfate, and its content is divided in Mg, S; The alleged micronutrient element of the present invention refers to zinc, iron, molybdenum, manganese and boron, is selected from zinc sulfate, ferrous sulfate, ammonium molybdate, manganous sulfate and active boron or borax, and its content is respectively in Zn, Fe, Mo, Mn, B.When calculating content, take ammonium molybdate as example, except molybdenum, also the nitrogen in the ammonium should be counted in the total nitrogen, the rest may be inferred by analogy.
This foliage fertilizer is the foliage fertilizer take water as solvent, comprises big or middle, micronutrient element and auxiliary agent, and difference with the prior art is macroelement (N+P 2O 5+ K 2O) content is greater than 70g/L, and its mass ratio is: N: P 2O 5: K 2O=(10-12): 1: (4-5); Moderate-element (Mg+S) content is greater than 30g/L, and its mass ratio is Mg: S=1: (2.5-3.5); Trace element (Zn+Fe+Mn+B+Mo) content is greater than 15g/L, and its mass ratio is Zn: Fe: Mn: B: Mo=(20-24): (14-18): (10-12): (5-6): 1; Sequestrant content is 5-35g/L; Wetting agent content is 0.05-0.3g/L.
Preferred macroelement (N+P 2O 5+ K 2O) content is 80-90g/L, its mass ratio is constant, moderate-element (Mg+S) content is 35-45g/L, its mass ratio is constant, trace element (Zn+Fe+Mn+B+Mo) content is 20-30g/L, its mass ratio is constant, and sequestrant content is 15-25g/L, and wetting agent content is 0.1-0.2g/L.
Described sequestrant is selected from EDTA, quadrol or citric acid etc., its effect be with in, trace element forms inner complex, thereby suppresses the generation of insoluble phosphate.
Described wetting agent is selected from anionic or nonionic surface active agent, such as alkyl-sulphate, alkylsulfonate, lauroyl diethanolamine, coconut oil diethanolamine or fatty alcohol-polyoxyethylene ether etc., its effect is the surface tension that reduces solution, improve solution in the blade face wettability of the surface, make it even spread, prevent that pearl from falling, prolong solution residence time of blade surface to guarantee that corn is to the abundant absorption of nutrient.
Described active boron is four water eight borate two sodium (Na 2B 8O 134H 2O), boracic 20.9% is a kind of new and effective instantly-soluble borate, also claims instant boron.
Nitrogen, phosphorus, potassium, magnesium, sulphur, zinc, manganese, boron, molybdenum and iron are necessary in this composite foliage fertilizer, but each element ratio can adjust in above-mentioned given range depending on particular case according to the principle of soil testing and fertilizer recommendation, if then can select N: P such as the Soil Phosphorus element is abundant 2O 5: K 2O=12: 1: 5, then can select N: P if the Soil Phosphorus element wanes 2O 5: K 2O=10: 1: 4, the rest may be inferred by analogy.
The preparation method of this foliage fertilizer be will metering nitrogen, phosphorus and the potassium raw material solution A that obtains soluble in water, the pH value of regulating described solution A with sulfuric acid gets solution B to 3-4; With the metering in, the trace element materials solution C that obtains soluble in water; The sequestrant that adds metering in the described solution C gets solution D in the 50-80 ℃ of lower 1-2h of stirring; The wetting agent of metering is mixed and added to described solution B and described solution D in the 20-50 ℃ of lower 0.5-1h of stirring; Add water to certain volume, remove by filter at last the non-water soluble impurity of bringing in the raw material and get product.
The preparation optimised process is preferably 60-70 ℃ of chelating temperature, time 1.5-2h; 30-40 ℃ of moistened surface treatment temp, time 0.8-1h.
This composite foliage fertilizer is watered dilution 500-800 doubly when using, mu is used diluent 100-150kg, sprays in the back side upper, middle part blade, particularly blade.Respectively spray 1 time in jointing stage, typhon mouth phase, tasseling stage, flowering period.Average stimulation ratio can reach more than 12%.Rain if spray to meet in the rear 5h, then should mend and execute.
