Abstract
The invention relates to a liquid composite foliar fertilizer special for rape. Water is used as a solvent of the liquid composite foliar fertilizer, and the liquid composite foliar fertilizer comprises macronutrients, medium nutrients, micronutrients, a beneficial element and assistants; the content of the macronutrients including N, P2O5 and K2O is more than 70g/L, and the mass ratio of N:P2O5:K2O is (13-15):1:(4.5-5.5); the content of the medium nutrients including Mg and S is more than 20g/L, and the mass ratio of Mg:S is 1:(1.5-2.5), the content of the micronutrients including Zn, Mn, B and Mo is more than 10g/L, and the mass ratio of B:Zn:Mn:Mo is (16-18):(11-13):(7-9):(1.5-2):1; the content of a chelant is 5-35g/L; and the content of a wetting agent is 0.05-0.3g/L. When applied, the liquid composition foliar fertilizer is diluted with water by 500-800 times, one mu of rape needs 50-100kg of the diluted composite foliar fertilizer, and the diluted composite foliar fertilizer is sprayed to the upper and middle parts of leaves, especially to the backs of leaves once respectively in a peduncle-growing period, an early flowering period and a blooming period of the rape, and the average production increase rate is higher than 15%.
Description
One, technical field
The present invention relates to a kind of chemical fertilizer, particularly polyelement composite fertilizer exactly is a kind of liquid composite foliar fertilizer special for rape.
Two, background technology
Rape is one of main oil crops of China, has the advantages that fertilizer requirement is large, fertilizer tolerability is strong, and the raising of its output, benefit is comparatively close with the fertilising relation.Rape is in growth and development process, and each growing stage is consistent with plant dry substance accumulation amount trend to the absorbed dose of the nutritive substances such as nitrogen, phosphorus, potassium.Nitrogen can promote organism growth to grow, and increases branch, spends polygonal many; Phosphorus can promote the bud differentiation of root system development and growing tip, increases kernal number, improves dry granular and weighs and oleaginousness; Potassium can increase disease resistance, cold hardiness and the capacity for the resistance to lodging of rape, promotes chlorophyllous formation, accelerates the running of photosynthate; " colored and unreal " can appear in rape boron; Lack the zinc root system development poor; The a lack of sulfur Seedling root is short and rare, and leaf is few and little; A lack of sulfur was spent little and was lacked flowering period, and empty angle fruit is many, yields poorly.Therefore, spray rational foliar nutrient at rape peduncle-growing period for rapeseed, early flowering season, full-bloom stage and can improve yield of rape 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 rape, so-called full nutrient pack oil scraper dish grow needed a large amount of, middle amount and micronutrient element, 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 and P
2O
