Abstract
The invention provides a fertilizing method for effectively reducing content of heavy metal cadmium in tobacco leaves and aims to reduce the content of cadmium in the tobacco leaves and weaken harm of smoking to the human body. A common fertilizer is adopted as a raw material, the cost is low, the content of cadmium in the tobacco leaves in acid soil can be obviously reduced by fertilizing, the application range is wide, secondary pollution to the soil cannot be caused, and the quality and the yield of the tobacco leaves cannot be influenced.
Description
Technical field
The invention belongs to tobacco planting technical field, be specifically related to the fertilizer ratio method of heavy metal cadmium content in a kind of effective reduction tobacco leaf.
Background technology
Smoking is harmful to your health, and the tar often that people pay close attention to, on the impact of human body, is difficult to recognize that heavy metal (as cadmium) in tobacco is to initiatively or the harm of involuntary smoker's health.Nowadays, along with the health perception of people self improves constantly, the content of beary metal in tobacco has become the focus that people pay close attention to.Heavy metal in tobacco, in aspiration procedure, enters human body by main flume, causes potential harm to human body.Increasing research confirms, smoking has become one of main source of some heavy metal of smoker.
The measure that current solution tobacco heavy metal is polluted has phytoremediation, but this method processing time long, take effect slow, but also the value of soil can be made to be affected.Somebody proposes to adopt physics, the principles of chemistry to administer the heavy metal pollution of tobacco, can solve heavy metal pollution problem fast and effectively, but the disposable input of this method is high, and without investment repayment, is difficult to apply in ongoing operations.
Summary of the invention
The object of the invention is: the content reducing heavy metal cadmium in tobacco leaf, weaken the harm that smoking produces human body.
After using the transplantation of seedlings of base manure cigarette, in the mode of topdressing, use soluble in water for fertilizer.The ratio of potash and long-term efficiency bicarbonate ammonium 2:1 is adopted to apply fertilizer.First time topdresses and uses potash 5g/ strain and long-term efficiency bicarbonate ammonium 2.5g/ strain, and second time is topdressed and used potash 10g/ strain.
Advantage of the present invention is: method is simple, and raw material easily obtains, practical, is convenient to promote in Production of Large Fields.
The vega soil pH value of Zhuzhou City of Hunan Province Chaling County is on the low side, and the local general potassium sulfate that adopts is used as the fertilizer that topdresses, potassium sulfate KCl production, and containing sulfate radical and free acid, chronic administration can make soil acidity increase the weight of.And the present invention adopts long-term efficiency bicarbonate ammonium and potash as topdressing fertilizer, both are all alkaline fertilizer, and particularly potash is strong basicity fertilizer, chronic administration, the pH value of acid ground can be made to increase, reduce the content of heavy metal in soil available state, finally reach the object reducing cadmium content in tobacco leaf.Nutritive element required for tobacco growing can also be provided simultaneously, ensure the seed output and quality of tobacco.
Embodiment
In order to make the object of the embodiment of the present invention, technical scheme and advantage clearly, carry out clear, complete description by the technical scheme in the embodiment of the present invention below.
Embodiment 1: carry out the pot experiment reducing cadmium content in tobacco leaf, this test is weeded tobacco proving ground, garden in Agricultural University Of Hunan and carried out, adopt zhuzhou, hunan province city Chaling County red farm vega soil, Cadmium in Soil content is 0.587mg/kg, and pH value is 4.77.Test kind adopts cloud and mist 87 and K326, and test period is 5 to September in 2014.
Adopt diameter 31cm, the pot experiment basin of high 28cm, every basin dress 15kg red farm vega soil, then in basin, plant cloud and mist 87 and K326 two tobacco bred tobacco seedlings, the strain of every basin 1, each kind arranges 3 repetitions, adopts identical Routine Management (adopting locality, Chaling to practise normal management) in each test basin.Tobacco basal dressing within 15 days, topdress afterwards by first time, and fertilizing amount is potash 5g/ strain and long-term efficiency bicarbonate ammonium 2.5g/ strain, within 15 days, topdresses for the second time afterwards, uses potash 10g/ strain.Contrast adopts potassium sulfate as the fertilizer that topdresses, and topdressing amount is 7.5g/ strain for the first time, and second time fertilizing amount is 10g/ strain.Gather in the crops after tobacco leaf maturation, and carry out block sampling to tobacco leaf, getting 1 to 5 leaves is inferior leads, and 6 to 10 leaves are middle leaf, and 11 to 15 is upper leaf, measures the content of cadmium at the upper, middle and lower portion leaf that 2 product grow tobacco.
As can be seen from result of the test table 1 and table 2, compared with the control, after adopting fertilizing method of the present invention, cadmium content in cloud and mist 87 and K326 tobacco leaf all significantly reduces, average reduction rate is respectively 24.93% and 45.04%, it can also be seen that, the present invention to the strong K326 of cadmium accumulation ability to fall cadmium effect comparison cloud and mist 87 remarkable.The amount that fertilizing method of the present invention makes the cadmium acrial part of each site absorption in tobacco move obviously reduces.No matter be tobacco leaf, or absorb total amount, all decrease to some degree.Particularly at the middle leaf of tobacco, cadmium content reduces fairly obvious.
Table 1 adopts the impact (unit: mg/kg) on cloud and mist 87 cadmium content after fertilization ratio of the present invention
| Inferior leads | Middle leaf | Upper leaf | |
| Contrast | 22.65 | 14.10 | 11.34 |
| Cloud and mist 87 | 16.42 | 11.59 | 8.09 |
| Reduction rate | 27.51% | 17.80% | 28.66% |
Table 2 adopts the impact (unit: mg/kg) on K326 cadmium content after fertilization ratio of the present invention
| Inferior leads | Middle leaf | Upper leaf | |
| Contrast | 26.58 | 15.88 | 11.69 |
| K326 | 12.75 | 8.89 | 8.12 |
| Reduction rate | 52.03% | 44.02% | 30.54% |
As can be seen from result of the test table 3 and table 4, compared with the control, after adopting fertilizing method of the present invention, the pH value of cloud and mist 87 and K326 planting soil and the content difference opposite sex of available Cd are significantly.The contrast soil pH value using potassium sulfate is low, and available Cd content is high, and uses fertilizer ratio process of the present invention, improves the pH value of soil, reduces the content of soil available Cd, the final cadmium content reduced in tobacco leaf.
Table 3 adopts the impact on cloud and mist 87 planting soil pH value and available Cd content after fertilization ratio of the present invention
Table 4 adopts the impact on K326 planting soil pH value and available Cd content after fertilization ratio of the present invention
