Embodiment

[0042] Embodiment: by weight percentage, take humic acid 1.0%, sodium silicate 0.5%, corn stalk is cut into 1cm long section, gets remainder after pulverizing. Mix humic acid, sodium silicate and corn stalks evenly to make an additive, and sprinkle it on the soil surface during site preparation, with an amount of 10.0kg m -2 , After application, plow to make it evenly mixed with 30cm deep ginseng bed soil, and then plant ginseng.

[0043] The present invention cannot replace other field management measures, and the present invention can select other plant stalks according to local resources in the absence of corn stalks.

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: [0001] The invention belongs to the field of traditional Chinese medicine modernization and relates to a method for reducing lead content in ginseng roots. Background technique: [0002] At present, countries all over the world have generally reacted strongly to the excessive heavy metal content in traditional Chinese medicine. Some countries have explicitly banned the import of certain raw materials and Chinese patent medicines. Many countries have established strict heavy metal control standards for the import of herbal medicines, including ginseng and its products. [0003] According to the investigation of the environmental monitoring department of the Ministry of Agriculture, the area of ​​cultivated land polluted in my country currently accounts for 1 / 5 of the total area, and the area polluted by heavy metals accounts for more than 80% of the total area of ​​pollution. The content of harmful heavy metals in soil and plants shows an obvious positive corr...
