Abstract
The invention provides a technology for effectively reducing accumulated heavy metal cadmium and lead in tobacco leaves, belonging to the field of tobacco planting technology. The key technology is as follows: before transplanting and ridging tobacco seedlings, applying a certain amount of humic acid into soil so as to effectively reduce the absorption of the tobacco leaves to soil cadmium and lead. The method is simple and easy, and practical and reliable, thus being a method which is less in investment, and capable of effectively reducing the pollution of soil cadmium and lead to tobacco leaves.
Description
Technical field
The invention belongs to tobacco planting technical field, be specifically related to a kind of method of heavy metal cadmium, lead contamination in effective reduction tobacco leaf.
Background technology
The heavy metal such as cadmium, lead is to the equal environmental contaminants of toxic effect of animals and plants, has very strong animal migration in farmland-soil system.This class heavy metal pollution not only affects the output of crops, also easily in crop, accumulates, and by food chain, enters human body, has a strong impact on the health of human body.Existing research shows, cadmium poisoning can cause renal tubule malabsorption again, makes low molecular weight protein and the loss such as calcareous, the long-term osteomalacia that easily forms, arthralgia, fracture and textured bone etc.; The usefulness that also can affect other beneficial elements in body, causes the problems such as hepatorenal damage, poor appetite, insomnia.And further to find that cadmium has in human body certain carcinogenic and cause gene mutagenicity in research.Lead makes vitamin C form the low ascorbic acid lead salt of solubility, thereby disturbs absorption and the utilization of iron, causes the diseases such as hypoferric anemia.Tobacco is a kind of plant that is easy to accumulate heavy metal, particularly from soil, absorb cadmium and with abnormal high concentration enrichment in blade.Heavy metal in tobacco leaf enters human body by main flume in aspiration procedure, and human body is caused to potential harm.In recent years, Chinese scholars has been carried out a large amount of research work to tobacco heavy metal pollution, has confirmed that soil is the main factor that affects content of beary metal in tobacco leaf.Therefore, control heavy metal in soil content, become the most important method of tobacco heavy metal pollution that solves.
To tobacco-growing soil heavy metal pollution state; carried out at present extensive work to reduce the absorption of tobacco leaf to heavy metal-polluted soil; except the Basic tobacco field of making rational planning for, protection tobacco planting environment, reduce heavy metal pollution and strictly control fertilizer special for tobacco quality etc.; the most frequently used method is used various modifying agents exactly; as fertilizers such as the inorganic amendments such as lime, attapulgite, active carbon or chicken manures; change the absorption property of soil pH value, the content of organic matter, soil etc., reduce mobility and the bioavailability of heavy metal.But the modifying agent such as lime, attapulgite amount of application is larger, and easily affect the character of soil, cause degradation bad reaction under soil compaction, fertility; Fertilizer is a certain amount of heavy metal of content own.Chinese patent CN102047808A has invented a kind of method of utilizing arbuscular mycorrhiza to reduce tobacco heavy-metal residual, but the method need to expand numerous fungi and cultivate Mycorrhizal cigarette seedling, and method is more complicated, and popularization is restricted.Therefore it is necessary, selecting a kind of technical measures of more practical simplicity effectively to reduce tobacco heavy metal.
Summary of the invention
The object of the present invention is to provide a kind of method that can reduce heavy metal cadmium and lead content in tobacco leaf, comprise the following steps:
Before cigarette transplantation of seedlings ridging, at upper soll layer, evenly spread fertilizer over the fields humic acid, amount of application is 8kg/667m
2, the particle diameter of described humic acid is less than 2mm.
Advantage of the present invention is: method is simple, and key technology is easily grasped, practical, is convenient to promote in Production of Large Fields.The humic acid of using can pass through heavy metal cadmium and lead in flocculation, reduction, chelating or suction-operated stable soil, effectively reduces heavy metal cadmium and plumbous bioavailability, thereby reduces the absorption of tobacco leaf to cadmium, lead.In addition, humic acid contains several functions base, there are acid carboxyl and phenolic hydroxyl group, and neutral alcoholic extract hydroxyl group, ether, ketone group, aldehyde radical fat, amido and the amide groups of alkalescence, therefore in soil, can show various active, the multiple effect such as performance physics, chemistry, ecological aspect improvement soil.During humic acid is manured into soil, can improve the physical arrangement of soil, strengthen the fertility of soil; Neutralizing acid alkalescence, a lot of mineral elements in absorption, exchange, activating soil, improve crop to the utilization rate of azophoska etc.
The specific embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1: use humic acid and reduce the plot experiment of tobacco leaf to Cadmium in Soil, Pb accumulation, this test is carried out in Mou Zhiyan district, Chongqing, and test is that cigarette yellow earth is planted in locality with soil, Cadmium in Soil 0.425mg/kg, plumbous 40.18mg/kg.Test kind is cloud and mist 87, and test period is 4～October in 2012.
Adopt field plot trial, 3 processing, repeat 4 times, each community area 17m
2.Humic acid is evenly sprinkling upon tobacco-growing soil top layer, community, ridging then, epiphragma.May 18, transplanted cigarette seedling, later stage field management is produced regulation enforcement by tobacco.The ripe Hou An of tobacco samples community in batches, collects sample after baking.
From result of the test table 1, can find out, compared with the control, the humic acid of using low concentration and high concentration all significantly reduces heavy metal cadmium and plumbous content in tobacco leaf, and the reduction rate of cadmium is respectively 34.13%, 23.39%, and plumbous reduction rate is respectively 35.09%, 24.11%.Visible, using of humic acid can reduce tobacco leaf to soil heavy metal cadmium and plumbous absorption, and amount of application is at 8kg/667m
2time reach good reduction rate.
The reduction rate of table 1 humic acid to heavy metal in tobacco leaf
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: the technical scheme that its in description still can be recorded aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement, does not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
