Abstract

The invention relates to a nutrient solution for water culture of pseudo-ginseng and a water culture method and belongs to the technical field of soilless culture of medical plants. According to the nutrient solution for water culture of the pseudo-ginseng, purified water is taken as a solvent, and ammonium chloride, sodium nitrate, water-soluble phosphoric anhydride, water-soluble potassium oxide, magnesium sulfate, boric acid, copper sulfate, ferrous sulfate, zinc sulfate heptahydrate, sodium molybdate, manganese sulfate heptahydrate and calcium nitrate tetrahydrate are added. The nutrient solution for water culture of the pseudo-ginseng is used for culturing pseudo-ginseng, tests prove that the nutrient solution can provide nutrients demanded by pseudo-ginseng in the water culture process, the survival rate of the pseudo-ginseng in the water culture process can be greatly increased, growth of fibrous roots of the pseudo-ginseng can be promoted, root exudates of the pseudo-ginseng are collected conveniently, and the successive cropping obstacle research process of the pseudo-ginseng is facilitated.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation of medicinal plants, and in particular relates to a notoginseng hydroponic nutrient solution and a hydroponic method. Background technique [0002] Panax notoginseng[ Panax notoginseng (Burk) F. H. Chen] is a plant of the genus Ginseng in Araliaceae. Its dried roots and rhizomes are a kind of precious Chinese medicinal materials, which have the effects of promoting blood circulation, removing blood stasis, reducing swelling and relieving pain. Notoginseng medicinal materials are widely used. Most of Chinese patent medicines for promoting blood circulation, removing blood stasis and treating cardiovascular and cerebrovascular diseases use notoginseng as the main raw material, such as Yunnan Baiyao spray and Danshen dripping pills. [0003] The distribution of Panax notoginseng is limited to a narrow area around 1500-1800 m above sea level and 23.5°N in southwest China. No wild popula...
