Embodiment 1

[0028] The method for breeding Lycoris safflower by aeroponic cuttings of bulbs of the present invention, the steps are as follows:

[0029] 1. Preparation of bulbs and acquisition of bulbs

[0030] 1) Treatment of bulbs: select artificially cultivated perennial Lycoris safflower bulbs with basically the same size and healthy growth, with an average circumference of 4.5 cm, an average fresh weight of 45 g, and an average scale layer of 14 layers. Remove the residual leaves, cut off the root system (do not damage the base plate), remove the brown film of the bulb, clean and dry.

[0031] 2) Cutting method to obtain bulbs: use the "cross-shaped" quartering method to cut the selected Lycoris safflower bulbs, first cut off 1 / 3 of the upper part of the bulb, and the remaining part is centered on the base of the bulb, according to the "ten" The shape is evenly cut into 4 equal parts to obtain bulb pieces.

[0032] 3) Auxin treatment and disinfection of bulb tubers: prepare 500mg / L...

Abstract

The invention discloses a Lycoris radiate bulb air culture cuttage propagation method. The Lycoris radiate bulb block air culture cuttage propagation method includes: 1) adopting a +-shaped quartering method to cut health Lycoris radiate bulbs with the same sizes to acquire bulb blocks; 2) soaking the bulb blocks in 500 mg / L IBA solution for 20 seconds, soaking the bulb blocks in 4 g / L carbendazim solution for 30 min to be disinfected, and air-drying the bulb blocks; 3) using an air culture method to rapidly induce growth of axillary buds and root systems of the bulb blocks, transplanting the bulb blocks into a medium to perform cuttage cultivation after a certain time, and acquiring child bulbs. the method uses Lycoris radiate mother bulbs to establish the clone rapid propagation system, and can rapidly induce the axillary buds to develop through air culture; the proliferation rate can reach 720%; the acquired child bulbs are consistent in hereditary basis, are stable in character, and are even in growth vigor; and the method can acquire mass bulbs in short time, and can provide mass raw materials for industries including ornamental horticulture and pharmacy.

Description

technical field [0001] The invention belongs to the technical field of Lycoris safflower cultivation, and relates to a method for breeding Lycoris safflower by aeroponic cuttings of bulbs, in particular to induce and accelerate the growth of axillary buds and roots of Lycoris safflower bulbs by aeroponic cultivation. Background technique [0002] Lycoris radiate (Lycoris radiate) is a perennial herb of the genus Lycoris in the family Amaryllidaceae. It has spherical bulbs underground and is covered with dark brown membranous scales. Its flowers are unique and gorgeous, graceful and graceful, and have high ornamental value. They can be used as cut flowers, potted flowers and ground cover plants for viewing flowers and leaves. Its bulbs contain more than 10 kinds of alkaloids and important medicinal ingredients such as Lycorine and Galanthamine, and are widely used in medicine and biopharmaceuticals. In addition, its bulbs are also rich in starch and sugar gum, which can be u...
