Description

A kind of liquid-type paddy rice compound foliar fertilizer special
One, technical field
The present invention relates to a kind of chemical fertilizer, particularly polyelement composite fertilizer exactly is a kind of liquid-type paddy rice compound foliar fertilizer special.
Two, background technology
Paddy rice is the topmost food crop of China.Will experience all one's life of paddy rice and nourish and grow and two stages of reproductive growth, wherein, the Sheng phase of tillering in the vegetative growth phase is the nutrition peak period of rice absorbing nitrogen, phosphorus, potassium.The paddy rice generative growth phase comprises jointing-booting stage, full heading time and During Grain-filling.The growth characteristic of paddy rice reproductive stage is the long fringe of long shoot, bloom, solid, form and substantial seed, this is the main phase of capturing high yield, especially will pay attention to nutrition recuperating in the cultivation.Therefore, spray rational foliar nutrient and can improve rice yield and quality in begin phase, early flowering season, filling stage of rice tillering early stage, jointing.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 paddy rice, so-called full nutrition comprises needed a large amount of, the middle amounts of rice growth and micronutrient element and beneficial element, and technical problem to be solved is the consistency of various nutrient elements in solution.
The alleged macronutrient of the present invention refers to nitrogen, phosphorus and potassium, is selected from urea, potassium primary phosphate, saltpetre or vitriolate of tartar, and its content is respectively with N and P 2O 5And K 2The O meter; Alleged middle amount nutritive element is magnesium and sulphur, is selected from sal epsom, zinc sulfate and manganous sulfate, and its content is divided in Mg, S; Alleged micronutrient element is zinc, molybdenum, manganese and boron, is selected from zinc sulfate, ammonium molybdate, manganous sulfate, active boron or borax, and its content is respectively in Zn, Mo, Mn, B; Alleged beneficial element is silicon, is selected from Starso, and its content is in Si.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, beneficial element and auxiliary agent, and difference with the prior art is macronutrient (N+P 2O 5+ K 2O) content is greater than 70g/L, and its mass ratio is N: P 2O 5: K 2O=(6-8): 1: (3-5); Middle amount nutritive element (Mg+S) content is greater than 20g/L, and its mass ratio is Mg: S=1: (2-3); Micronutrient element (Zn+Mn+B+Mo) content is greater than 10g/L, and its mass ratio is Zn: Mo: B: Mn=(4-6): (1-1.5): (1-1.5): 1; Total nutrient (N+P 2O 5+ K 2O+Mg+S+Zn+Mo+B+Mn) content is greater than 110g/L, beneficial element Si content 0-10g/L.Sequestrant content is 5-35g/L, and wetting agent content is 0.05-0.3g/L.
Preferred macroelement (N+P 2O 5+ K 2O) content is 85-95g/L, and its mass ratio is constant, and moderate-element (Mg+S) content is 20-30g/L, and its mass ratio is constant, and trace element (Zn+Mn+B+Mo) content is 15-25g/L, and its mass ratio is constant, total nutrient (N+P 2O 5+ K 2O+Mg+S+Zn+Mo+B+Mn) content is greater than 120g/L, and beneficial element Si content is 6-8g/L, and sequestrant content is 8-12g/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, 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 paddy rice 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 silicon are necessary in this composite foliage fertilizer, but each element ratio can be according to the principle of soil testing and fertilizer recommendation, adjust in above-mentioned given range depending on particular case, if abundant then can to select Zn: Mo: B: Mn be 4 such as Zn element in the soil: (1-1.5): (1-1.5): 1, if to wane and then can select Zn: Mo: B: Mn be 6 to the Zn element in the soil: (1-1.5): (1-1.5): 1, 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, and get solution B with the pH value of sulfuric acid regulation solution A to 3-4; With in the metering, trace and the beneficial element raw material solution C that obtains soluble in water; In solution C, add the sequestrant of metering in the solution D of 50-80 ℃ of lower stirring reaction 1-2h; The wetting agent stirring 0.5-1h under 20-50 ℃ that measures is mixed and added to solution B and solution D, add water to certain volume, remove by filter the non-water soluble impurity of bringing in the raw material and namely get product.
This foliage fertilizer is for preventing calcium phosphate precipitation, adopting the interpolation sequestrant is that master, reduction pH value of solution are auxiliary terms of settlement, sequestrant can with in, trace element forms has sterically hindered inner complex and generate to suppress precipitation, reduce pH and be conducive to improve phosphatic solubleness.
Optimum process condition 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 50-100kg, sprays in the back side upper, middle part blade, particularly blade.Respectively spray 1 time in the early stage of tillering, phase jointing beginning, early flowering season, filling stage.Average stimulation ratio can reach more than 10%.Rain if spray to meet in the rear 5h, then should mend and execute.
