Embodiment 1

[0029] Such as figure 1 As shown, it shows a flow chart of the method for rapid cutting and rooting of Babao Sedum hydroponics in this embodiment, which is described in detail as follows.

[0030] Using the indoor hydroponic test method, the basic nutrient solution is 50% Hogland's nutrient solution, which includes 2.5mmol / L calcium nitrate tetrahydrate, 2.5mmol / L potassium chloride, 0.5mmol / L potassium dihydrogen phosphate, 0.5mmol / L L Magnesium sulfate heptahydrate, 25μmol / L boric acid, 2.25μmol / L manganese sulfate monohydrate, 1.9μmol / L zinc sulfate heptahydrate, 0.15μmol / L copper sulfate pentahydrate, 0.05mmol / L ammonium heptamolybdate and 5μmol / L Sodium iron ethylenediaminetetraacetate. Add plant growth regulator sodium naphthaleneacetate and potassium indolebutyrate to the basic nutrient solution to make their concentrations 0.2mg / L and 0.2mg / L, respectively.

[0031] Specifically, first prepare the basic nutrient solution: prepare mother liquor one (0.25mol / L calcium nitrat...

Abstract

The invention discloses a rooting method of Hylotelephium erythrostictum by using water culture and cutting, which comprises the steps: intercepting a stem section of Hylotelephium erythrostictum without plant diseases and insect pests, inserting the base of the stem portion into a rooting culture medium, and culturing at 18 to 25 DEG C for 1 to 3 weeks, wherein the rooting culture medium is a basic nutrient solution to which a plant growth regulator is added, the plant growth regulator comprises auxin analogue and a cytokinin analogue at a concentration ratio of 1:1, and the basic nutrient solution is a 50% Hoagland nutrient solution. The quick rooting method of Hylotelephium erythrostictum by using water culture and cutting greatly improves the rooting rate and root quantity of Hylotelephium erythrostictum by using water culture and cutting, and solves the key technical problems about rapid propagation of Hylotelephium erythrostictum and has great significance for rapid propagation and industrialized nursery and production of Hylotelephium erythrostictum.

Description

Technical field [0001] The invention belongs to the technical field of rapid rooting of sedum plants, and specifically relates to a method for cutting roots of Babao sedum hydroponics. Background technique [0002] Babao sedum is a perennial succulent herbaceous plant of the sedum family, genus sedum, also known as gorgeous sedum and long-medicine sedum. The underground stems of Babao Sedum are thick, the above-ground stems are clustered, sturdy and erect. The whole plant is gray-green, and the plant height is 30-50cm. The leaves are whorled or opposite, obovate and fleshy, and have wavy teeth. The corymbs are densely packed like flat heads, with a diameter of 10 to 13 cm. The flowers are pale pink, and there are also white, purple, and rose red varieties. They are the most colorful species in the Crassulaceae. Therefore, the Eight Treasure Sedum is commonly used as a slope protection ground cover plant to coordinate with other flowers to arrange flower beds, flower borders or p...
