Abstract
The invention discloses a method for increasing potassium content of upper tobacco leaf. When lower-secondary-shed tobacco leaves are harvested, an infusion device is directly inserted in a stalk of the upper tobacco leaf to naturally infuse a potassium salt solution. According to the method for increasing the potassium content of the upper tobacco leaf, the infusion device is directly inserted in the stalk of the upper tobacco leaf to naturally infuse the potassium salt solution, so that potassium elements are directly infused into the body of a tobacco plant; compared with the existing methods of spraying potash fertilizer, smearing growth hormone and the like, the method provided by the invention has the advantages that the potassium content of the upper tobacco leaf can be directly and quickly increased, operations are simple, effects are achieved quickly, the utilization rate of a potassium element is high and the like; meanwhile, the stage for performing the method is a stage of harvesting the lower-secondary-shed leaves, the stage is especially beneficial to absorption and utilization of the potassium element; in conclusion, the structure of the utilized infusion device is simple, operations of the method are simple, the resource of materials is wide, the cost is low, the potassium content of the upper tobacco leaf can be remarkably increased, the smoking quality of the leaf is improved, and the method can be widely popularized and applied in tobacco planting regions.
Description
Technical field
The present invention relates to a kind of method improving upper tobacco leaf potassium content, belong to flue-cured tobacco cultivation technical field.
Background technology
Potassium can promote synthesis and the accumulation of the material that carbohydrate, aromatics etc. are relevant with quality in tobacco leaf, thus affects the aroma quality of flue-cured tobacco, perfume quantity; Potassium burns relevant with tobacco leaf, and the tobacco leaf that potassium content is high has good flammability and glows holds firepower, and tobacco leaf ignition temperature is low, is conducive to reducing harmful substance and produces, improve quality and the safety of tobacco product.The potassium content in tobacco leaf of the U.S. and Zimbabwe is many 4% ~ 6%, and the potassium content in tobacco leaf of China is lower, the average potassium content of China's tobacco leaf is only 1% ~ 2%, and especially upper tobacco leaf potassium content is lower, and lower potassium content is the key factor that restriction China quality of tobacco improves.Therefore, seek the approach improving potassium content of tobacco leaf, particularly how improving upper tobacco leaf potassium content is problem demanding prompt solution.
Relevant scholar it is also proposed some agronomic measures to raising upper tobacco leaf potassium content, such as Rational Application nitrogenous fertilizer, spray or smear growth hormone, comprehensively use biological potassium fertilizer, organic potassic fertilizer and rich potassium green manure etc., although these measures have certain effect to raising upper leaf potassium content, but be not complicated operation be exactly that expense is too high, operability is not strong in a word.The present invention, is in practical operation being improved repeatedly for many years, sums up the method for a set of simple possible.
Summary of the invention
The technical problem to be solved in the present invention: a kind of method improving upper tobacco leaf potassium content is provided, simple to operate, draw materials extensively, with low cost, upper tobacco leaf potassium content can be significantly improved, improve quality of tobacco, to overcome the deficiencies in the prior art.
Technical scheme of the present invention:
Improve a method for upper tobacco leaf potassium content, when gathering lower two canopy tobacco leaf, the stem stalk place utilizing infusion set to be directly inserted in upper tobacco leaf inputs potassium salt soln naturally.
Described two canopy tobacco leaves of gathering down are after flue-cured tobacco transplanting 75 ~ 80 days periods.
Described potassium salt soln is KH
2pO
4, K
2sO
4or KNO
3, mass percent concentration is 10% ~ 15%, and every strain consumption is at 20 ~ 30 ml.
Described infusion set comprises hollow pinhead and bottle, is provided with circular hole at bottle body bottom.
The hollow pinhead of described infusion set is inverted the stem stalk place be inserted in bottom upper blade, is specially the stem stalk place of several 6-8 sheet blade from top to bottom, keeps hollow pinhead and stem stalk angle to be 30 degree ~ 45 degree.
Beneficial effect of the present invention:
The present invention utilizes infusion set to be directly inserted in the stem stalk place input potassium salt soln of upper tobacco leaf, directly potassium element is inputted in cigarette strain body, this kind of method spray potash fertilizer with existing, smear the methods such as growth hormone compared with, can potassium content in fast lifting upper tobacco leaf, have simple to operate, instant effect, potassium element availability advantages of higher.When being chosen as two canopy tobacco leaf under tobacco leaf picking period of the present invention, this period is beneficial to upper tobacco leaf absorbing potassium element especially simultaneously.The selection of potassium salt soln concentration and every strain consumption in the present invention, be that inventor determines according to actual effect, it has taken into account the availability of potassium salt soln and the balance of cost.The present invention adopts oblique cutting, natural inflow mode, and potassium liquid all flows into stem stalk required time and is approximately 25-35 days, and this mode can allow saline solution all slowly flow in stem stalk, is beneficial to the absorption rate improving potassium salt soln.
In a word, the present invention's infusion set structure used is simple, and whole method is simple to operate, draws materials extensively, with low cost, can significantly improve upper tobacco leaf potassium content, improve quality of tobacco, can in tobacco planting area wide popularization and application.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
embodiment:
Embodiment:
As the infusion set that Fig. 1 is in the present invention, it comprises hollow pinhead 1 and bottle 2, is provided with the small sircle hole that diameter is 1-2mm bottom bottle 2, and this circular hole can ensure sylvite liquid can be made naturally to flow in stem stalk in atmospheric pressure effect.
The method that the present invention improves upper tobacco leaf potassium content is specially: when gathering lower two canopy tobacco leaf, to be generally after flue-cured tobacco transplanting 75 ~ 80 days, the stem stalk place utilizing aforementioned infusion set to be directly inserted in upper tobacco leaf inputs potassium salt soln naturally, hollow pinhead 1 is inverted the stem stalk place be inserted in bottom upper blade, be specially the stem stalk place of several 6-8 sheet blade from top to bottom, keep hollow pinhead and stem stalk angle to be 30 degree ~ 45 degree.
Described potassium salt soln is KH
2pO
4, K
2sO
4or KNO
3, mass percent concentration is 10% ~ 15%, and every strain consumption is at 20 ~ 30 ml.
Can find out from table one, infusion set takes different inserted modes, has impact to the potassium oxide content of upper tobacco leaf, adopts time oblique cutting (hollow pinhead and stem stalk angle are 30 degree ~ 45 degree) and is comparatively beneficial to upper tobacco leaf absorbing sylvite liquid.When the mass percent concentration of potassium salt soln is 10% ~ 15%, increase potassium effect more obvious.
Can find out from table two, adopt the KH of 10% concentration
2pO
4or KN0
3when upper tobacco leaf is processed, compared with the upper tobacco leaf not inputting sylvite, the content of potassium oxide is respectively 1.96% and 1.92%, and the potassium oxide content not inputting the upper tobacco leaf of sylvite is then 1.27%, it can thus be appreciated that the present invention significantly can improve the content of potassium oxide in upper tobacco leaf.Other chemical composition index is also better than contrast, and quality of tobacco improves successful.
