Description
One, technical field
The present invention relates to a kind of chemical fertilizer, particularly polyelement composite fertilizer, be exactly a kind of liquid-type tobacco compound foliar fertilizer special.
Two, background technology
As the extensive Important Economic crop of plantation in world wide, tobacco is wide in Chinese cultivated area, and China is that first kind of tobacco planted big country in the world at present.China's tobacco industry is that country realizes 1,000 hundred million yuans of finance accumulative totals every year, but the Tobacco quality still has larger gap with the quality of tobacco of world High Quality Tobacco production country on the whole, and quality of tobacco has become the bottleneck of restriction Chinese tobacco industry development.Quality of tobacco is to weigh the important indicator that tobacco produces, and the tobacco leaf hypertrophy of quality better is moderate, and dry matter content is abundant, roasting rear oil content foot, and color and luster is orange, and fragrance is dense, and incendivity is good, and grey matter is slim and graceful.Nutritive element is the basic substance that the tobacco leaf dry-matter is made in the cigarette strain, and along with developing rapidly of leaf tobacco production, high-quality tobacco mass-producing, standardized process are accelerated rapidly, and technique of balanced fertilizer becomes the core technology that high-quality tobacco is produced gradually.Tobacco is a kind of plant that potassium is avoided chlorine of liking, and needs a large amount of K, N, P element in the tobacco growing process, and nitrogen is the most important element that affects tobacco growing growth and quality product.Nitrogen hunger causes yielding poorly, and is of poor quality, and nitrogen is excessive postpones maturation, and the cured tobacco leaf color is not good, and nicotine content is high, and quality is also bad; It is yellow slow, remaining green when it is due to become yellow and ripe late-maturing that the excessive meeting of nitrogen supply falls blade.Phosphorus grows the most significantly to tobacco growing that effect is the maturation that is conducive to blade, can improve the color of tobacco leaf after roasting.But phosphorus is due at the early stage root system development of flue-cured tobacco with strengthen and to play an important role aspect resistance, so phosphorus should be specifically noted that early stage supply.Improve potassium content in tobacco leaf, can improve tobacco leaf visual appearance, elasticity and incendivity.Potassium content is a key factor that determines the quality of tobacco quality, is called " Quality Element " of tobacco.Simultaneously, also need numerous trace elements in the tobacco growing process, as: trace element molybdenum is the metal ingredient of nitrate reductase, play the electronics transfer function, it is again a kind of composition of phase ferritin in nitrogenase, work in the fixed nitrogen process, thereby play a very important role in nitrogen metabolism, photosynthesis, breathing; Boron not only affects the mitogenetic of tobacco growing cell, is regulating the transportation of glucide in the tobacco body, but also affects the reproductive growth of tobacco; Zinc is the necessary element of synthetic auxin, is again the catalyzer of organism endoenzyme simultaneously.Trace element can be conducive to reduce disease and pest with nitrogen, phosphorus and being used in conjunction with of potassium.Therefore, prevent that nitrogen, potassium ratio from absorbing imbalance and large Meso-and micro-nutrients and absorbing that to coordinate be the basic measures that improve quality of tobacco.
Solid fertilizer is difficult to accomplish big-and-middle micro-eurythmy and mixes, and the trace element in soil is not easily absorbed by plants by soil fixing.Employing science technology of preparing can be accomplished the large Meso-and micro-nutrients eurythmy of liquid fertilizer and be mixed.the all nutrition type liquid fertilizer has formula and can adjust flexibly, the multiple advantage such as convenient spraying, compare with the fertilising of solid fertilizer root, foliage-spray more is conducive to absorbing of tobacco plant, can satisfy high quality tobacco comprehensively and like potassium in process of growth, boron deficiency, lack the major physiological demands such as zinc, effectively improve the external and interior quality of tobacco leaf, conditioning tobacco plant photosynthetic efficiency and improving activity of root system, root/shoot ratio is increased, the thick fertilizer of tobacco leaf is roomy, fall yellow good, the rate of drying is high, fragrance is pure, output improves, simultaneously also can improve the resistance of cigarette strain, to multiple physiological disturbance (as black quick-fried leaf, potassium deficiency, boron deficiency, manganese deficiency, iron deficiency, scarce molybdenum disease etc.) desirable prevention effect is all arranged, good smoke rate is obviously increased, average price increases substantially.Yet may chemical reaction occur between big or middle, micronutrient element and cause nutrient availability to reduce, the residence time of foliar nutrient on the crop blade face also can directly affect 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.Contain tens kinds of elements in 5.0% ash content, but wherein only some is that plant is necessary and useful.So-called plant essential nutrient element is exactly indispensable element in plant growth and development process.If lacked, just can not completing, plant born at last the breeding cycle of seed of new generation through growing by seed germination.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 tobacco, so-called full nutrition comprises that tobacco growing grows needed a large amount of, middle amount 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, saltpetre or vitriolate of tartar, and its content is respectively with N, P
