Embodiment Construction

[0031]The present invention is based on the principles of simplicity, practicality, cost-effectiveness and high efficiency, and according to the principle that the ratio of auxin with appropriate concentration can promote plant rooting and the ratio of inorganic salt with appropriate concentration can promote plant growth, adopts the method of hydroponics with nutrient solution, and uses cold boiled water as the Medium, add naphthaleneacetic acid (NAA) 0.1mg / L, indolebutyric acid (IBA) 0.5mg / L, potassium nitrate (KNO 3 ) 900mg / L, ammonium nitrate (NH 4 NO 3 )820mg / L, potassium dihydrogen phosphate (KH 2 PO 4 )85mg / L, magnesium sulfate heptahydrate (MgSO 4 ·7H 2 O) 185mg / L, calcium chloride dihydrate (CaCl 2 2H 2 O) 220mg / L, disodium edetate (Na 2 -EDTA) 12.8mg / L, ferrous sulfate heptahydrate (FeSO 4 ·7H 2 O) 18.6mg / L was made into a nutrient solution, and the rooting of the hydroponic cuttings of Panax notoginseng was carried out. At the same time, the growth of green...

Abstract

The invention discloses a method for quick rooting of divaricate velvetplant root and rhizome by water culture and cutting and belongs to the technical field of rooting of the divaricate velvetplant root and rhizome. The method mainly comprises a basic formula of quick rooting culture solution, preparation for the quick rooting culture solution and a method for quick rooting by the water culture and cutting. According to the method disclosed by the invention, with simplicity, practicality, economy and high efficiency as the rule, and with the principle that the rooting of plants can be promoted according to the mixture ratio of auxin with proper concentration and the growth of the plants can be promoted according to the mixture ratio of inorganic salts with proper concentration, the divaricate velvetplant root and rhizome is rooted by the water culture and the cutting through adopting a water culture mode of nutrient solution with cold boiled water (river water or tap water placed for over 1-2 days) and the like as mediums; meanwhile, the growth of green alga is suppressed by means of blacking a container and other paths, quick rooting of the divaricate velvetplant root and rhizome by the water culture and the cutting is realized, the rooting speed, root amount, survival rate, plant robustness and the like of the divaricate velvetplant root and rhizome by the water culture and the cutting are greatly improved. According to the method disclosed by the invention, the survival rate of the divaricate velvetplant root and rhizome by the water culture can reach over 98 percent, the divaricate velvetplant root and rhizome can be rooted in 6-7 days, the root amount is abundant, and cuttings are quick in growth.

Description

technical field [0001] The invention belongs to the technical field of notoginseng rooting. Background technique [0002] Hydroponics is the cultivation of flowers using water as the medium. Compared with traditional soil cultivation, hydroponics has the characteristics of strong ornamental, clean and environmentally friendly, convenient maintenance and management, and less pests and diseases, so it is very popular among the public. At present, there are two kinds of hydroponic seedlings on the market, one is the real hydroponic seedlings; the other is the fake hydroponic seedlings that wash the rooted soil seedlings and use them for hydroponic cultivation, which is called soil washing seedlings. There are big differences in the structure and physiological characteristics of the soil-cultured root system and the water-cultured root system of the plant. After the soil-washed seedlings are hydrocultured, they often cause rotten roots due to physiological discomfort, and it is ...
