Description

A kind of flue-cured tobacco disease-resistant yield-increasing special-purpose foliage fertilizer

Technical field

The present invention relates to chemical fertilizer, relate in particular to a kind of flue-cured tobacco disease-resistant yield-increasing special-purpose foliage fertilizer.

Background technology

The root system of tobacco and blade are the organs that absorbs nutritive substance, and in tobacco planting process, except needs apply fertilizer by Root Absorption nutrition to tobacco root, foliage-spray is also one of approach of supply tobacco nutrition.For trace, be easy to by soil fixing, interim element or the organotrophy of being badly in need of, by Foliage Absorption, better effects if, act on also more direct, for a kind of high-quality foliage fertilizer, mu drops into less cost, and the quality of flue-cured tobacco and mu are benefited and can be obtained comparatively significantly improving.In the prior art, foliage fertilizer for tobacco is more, as Chinese patent (200610128428.X) " special-purpose tuanke foliage fertilizer for flue-cured tobacco ", to be made by xanthohumic acid, zinc sulfate, copper sulfate, ferrous sulfate, boric acid, potassium primary phosphate, saltpetre, root-inducing powder, ammonium molybdate, acetic acid, this fertilizer can significantly promote growing of cigarette strain group's phase and squaring period, obviously improve output and the output value of flue-cured tobacco, significantly improve flue-cured tobacco potassium content, reduce cl content, impel nicotine content more moderate, tobacco leaf chemical composition is coordinated.And for example Chinese patent (200610128383.6) " tobacco foliage fertilizer ", mainly make this fertilizer by timely this fertilizer of foliage-spray after pinching in cigarette strain by zinc sulfate, boric acid, potassium dihydrogen sulfate, magnesium sulfate, ferrous sulfate, can significantly promote the increase of upper leaf area, the particularly increase of width of blade, optimize the weave construction of upper leaf, promote nicotine content of tobacco leaves to reduce, potassium content increases considerably, thereby make blade attenuation, be easy to baking, improve quality of tobacco and visual appearance.Etc., the foliage fertilizer that these tobaccos are used is mainly to start with from increasing inorganic nutrients, does not seldom consider in other words the effect of organotrophy and plant growth regulating substance, thereby, with certain one-sidedness.

Foliage-spray selenium fertilizer can not only fast and effeciently improve tobacco leaf selenium content, reach the object of producing rich selenium tobacco leaf, can also effectively improve the economic characters of tobacco, improve the disease-resistant resistance in cigarette strain later stage, there is the effect of obvious upgrading, synergy, can also improve commercial grade and the industrial applicability of tobacco leaf.At present, about selenium-enriched foliage fertilizer (special selenium-rich foliage fertilizer, application number: 97119194.8; Selenium-enriched foliage fertilizer, application number: 200510017953.X; Selenium-enriched foliage fertilizer and its production and use, application number: 201010505935.7) study more, but because of its formula in all contain the main nutrient composition such as more nitrogen, phosphorus element, if spray on tobacco, easily cause flue-cured tobacco remaining green when it is due to become yellow and ripe late-maturing, be difficult to baking, Flue-cured tobacco Quality declines obviously.Therefore, above-mentioned several fertilizer that sprays all can not effectively be applied among rich selenium leaf tobacco production plantation.

Summary of the invention

Technical problem to be solved by this invention is: flue-cured tobacco disease-resistant yield-increasing special-purpose foliage fertilizer is provided, it can increase cured tobacco leaf selenium content, improve commercial grade and the industrial applicability of tobacco leaf, promote significantly rich selenium tobacco leaf sensory evaluating smoking's quality and raw tobacco material security simultaneously.

Technical scheme of the present invention is: a kind of flue-cured tobacco disease-resistant yield-increasing special-purpose foliage fertilizer, is characterized in that pressing row weight quota mixed dissolution by nutritive substance, growth regulatory substance, organic active substance, spreader-sticker and aqueous solvent makes:

(1) nutritive substance: Sodium Selenite 5-10 part, borax 1-3 part, zinc sulfate 1-5 part, manganous sulfate 1-5 part, Sodium orthomolybdate 5-10 part, saltpetre 10-20 part, potassium primary phosphate or saltpetre 20-30 part, magnesium sulfate 10-15 part,

(2) growth regulatory substance: naa 1-5 part;

(3) organic active substance: ammonium molybdate 0.5-1 part, 5～10 parts of potassium humates, 5～7 parts, amino acid;

(4) spreader-sticker: totally 4～12 parts of liquid detergent 2-10, starch and tweens, wherein, starch and tween mass ratio (3-2): 2;

(5) aqueous solvent: 40-60;

Step is as follows: water is added in reactor, while being heated to 40 DEG C, start to stir, in reactor, add ammonium molybdate, amino acid, the potassium humate that need dissolve in advance, continue to stir 15～20 minutes, mix; Add organic active substance, pH value is adjusted to 4.5～6.5, and decompression is heated to 75 DEG C, reacts 0.5～1 hour; When after completion of the reaction, be cooled to 30～40 DEG C, in reactor, add other fertilizer outside eliminating minute element fertilizer, stir 20～30 minutes; Treat that temperature drops to room temperature, mixing solutions is filtered, remove impurity, then further stir, make mixed solution full and uniform; The solution mixing obtaining is entered to finished product still, add starch and tween, mix.

Flue-cured tobacco often can run into coercing of the adverse circumstances such as temperature, moisture, disease and pest in whole breeding time, these all can affect the quality product of growing of cigarette strain and tobacco leaf.Some foliage fertilizer can improve the resistance of cigarette strain, reduces the incidence of disease, thereby gathers in the crops the tobacco leaf of more high-quality.Spray special-purpose foliage fertilizer in tobacco in seedling stage and can make cigarette seedling stalwartness, reduce the generation of anthrax, samping off, for high yield is laid a good foundation.Can obviously promote that the steady life of cigarette seedling is strong long, strengthen cigarette seedling disease resistance, improve the quality of cigarette seedling; Spray at field period, can promote plant strain growth stalwartness, significantly improve the ability of cigarette seedling viral diseases, balck shank, wildfire, reduce sickness rate.Respectively process all with rich ten thousand potassium effect optimums.
