Abstract
The invention discloses a method for reducing a lead content in a ginseng root, which belongs to the field of traditional Chinese medicine modernization. The method solves the problems of high lead content in the ginseng root and declined quality caused by high lead content of soil in a ginseng land. In the method, an additive is prepared by mixing a humic acid, a sodium silicate and a plant straw, then applied to the soil at the time of land preparation. The method is characterized in that: in percentage by weight, 0.5%-1.5% of humic acid, 0.2%-1.0% of sodium silicate and the plant straw which is cut into 1 cm are taken and smashed, then the balance is taken. The humic acid, the sodium silicate and the plant straw are mixed evenly and prepared into the additive. The additive is scattered on the surface of the soil in a dosage of 5.0-20.0 kg.m<-2>. The land is ploughed after the application of the additive. The additive is evenly mixed with 30 cm deep ginseng bed soil, then the ginseng is planted. The method is used for culturing the ginseng, can reduce the lead content in the ginseng root, promote the growth of the ginseng and improve the quality and output of the ginseng.
Description
Technical field:
The invention belongs to modern Chinese traditional medicine field, relate to a kind of method that reduces lead content in the ginseng.
Background technology:
At present, countries in the world generally exceed standard to the Chinese medicine content of beary metal and have strong complaints, and some country has prohibited some bulk drug and Chinese patent drug import, many countries to herbal medicine import set up strict heavy metal control criterion, this is comprising genseng and goods thereof.
Investigate according to environmental monitoring department of the Ministry of Agriculture; the arable area that present China is polluted accounts for 1/5 of the gross area; wherein the heavy metal pollution area accounts for more than 80% of gross contamination area; harmful heavy metal content is tangible positive correlation trend in soil and the plant, and to think little of environmental protection relevant with us for this.The heavy metal pollution of soil source mainly comprises: the air pollution that causes from the exploitation of steam power plant, smelter, oil exploitation and processing enterprise, construction material and manufacturing enterprise, the water body and the soil pollution that cause by trade waste, agricultural chemicals and chemical fertilizer, and the pollution that causes of other discarded object (vehicle exhaust, sewage mud, house refuse etc.).Retrieval shows, still finds no the effective ways that reduce plumbous residual quantity in the ginseng at present, and the present invention uses with humic acid, sodium silicate and after straw mixes, and has reached to alleviate the toxic action of lead-contaminated soil to genseng, has reduced the lead content in the ginseng.
Summary of the invention:
The object of the invention provides a kind of method that reduces lead content in the ginseng, is used for solving owing to join ground soil lead content height, the problem that causes the genseng quality to descend.
The method of lead content in the reduction ginseng of the present invention is with humic acid, sodium silicate and after straw mixes, and makes additive, is manured into soil when whole ground and finishes.It is characterized in that: by weight percentage, by humic acid 0.5%～1.5%, sodium silicate 0.2%～1.0%, plant straw are cut into the long section of 1cm, get surplus after the pulverizing.Humic acid, sodium silicate and straw are mixed, make additive, be sprinkling upon soil surface during whole ground, consumption is 5.0～20.0kgm
-2, turn over after using, itself and the dark ginseng bed soil of 30cm are mixed, plant ginseng then.
The effect of each component among the present invention:
1, the effect of humus.Humus is mainly cooperated to be used for finishing by ion exchange and complexing or huge legendary turtle to the inhibition of heavy metal ion toxic action.Humus has abundant activity functional groups, can various forms of combinations take place with heavy metal, thereby becomes the solubilizer or the fixative of heavy metal-polluted soil, and then influences form transformation and the mobility of heavy metal in soil environment.In addition, humus also contains a large amount of organic matters, has the characteristics of organic manure, also contains available nutrient simultaneously, so be again a kind of multi-functional organic-inorganic composite fertilizer, growth has facilitation to genseng.
2, the effect of sodium silicate.Sodium silicate is a kind of of silicate, and the inhibitory action of sodium silicate mainly is by generating silicate precipitates with heavy metal ion, change the form that exists of heavy metal in soil, cause water-soluble plumbous the minimizing, and its biological effectiveness finishes thereby reduce.In addition, silicon can also promote the synthetic and running of plant carbohydrates, improves the resistance to damage by disease and insect.
3, the effect of plant straw.
The plant straw can strengthen the adsorption capacity of soil to heavy metal, reduces absorption and the enriching quantity of plant to heavy metal.Genseng is perennial medicinal plant, and for a long time in the growth of same place, because the comminuted plants straw has stronger suction-operated, after humic acid and sodium silicate mixed, its slow releasing function can be kept its long-term effectiveness after sowing or the transplanting.In addition, the plant straw still is the organic manure resource that a kind of cheap, quantity is extremely abundant, can directly utilize, and it can increase the soil organic matter and nutrient content, is a kind of good soil conditioner and organic manure.
Test effect of the present invention:
Test is carried out in Jilin Agriculture University Fusong proving ground, and the genseng kind is " Da-maya ".
