Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0023] 1. Select inserts

[0024] From mid-to-late June to mid-to-late September, cut the required branches in the morning to keep the branches moist and avoid wilting; trim the clipped branches into cuttings as soon as possible. The stem diameter of the cuttings is 1-2 mm and the length is 1-8 cm, with 1-2 intact leaves and at least one node;

[0025] 2. Cutting substrate

[0026] Build a small bow shed on the seedbed, and the cutting substrate is a 1:1 mixture of sand and vermiculite, with a thickness of 10 cm;

[0027] 3. Cutting and management

[0028] Insert the cuttings into the wet cutting substrate as soon as possible. When cutting horizontally, the branches are required to be embedded in the substrate for 1 to 6 cm, and the leaves are exposed to the air. The cutting density should be such that the leaves do not overlap each o...

Abstract

The invention discloses a cutting seedling raising method of peltate yam rhizome. The method comprises the steps of firstly, branch collecting: from last twenty days of June to last twenty days of September, the portion of the peltate yam rhizome with vine length larger than 2m is sheared down, a sheared mouth is placed in water, and sheared peltate yam rhizome is stored in a shade place; secondly, branch cutting: sheared branches are trimmed into branches with 1 to 2 complete leaves and at least one burl to be used as stump plant, the diameter of stem of the stump plant is 1mm to 2mm, and the length of the stem of the stump plant is 1cm to 8cm; thirdly, cuttage: the stump plant is horizontally inserted in a damp cutting medium, the branch is buried in the medium by 1cm to 6 cm, the leaves are exposed in the air, and cuttage density is suitable if leaves are not overlapped; fourthly, management after cuttage: temperature is maintained between 25 DEG C to 33 DEG C, and humidity is maintained between 30% to 40% when cuttage is carried out, plant growth regulating substance solution hastening rooting and forming of corms is sprayed in time during a managing and protecting period; fifthly, transplanting: after one or two months, the peltate yam rhizome after cuttage sprouts adventitious roots and new branches, a planting percent reaches more than 95%, and transplanting requirements are met.

Description

technical field [0001] The invention belongs to the technical field of asexual propagation of plant seedlings, and relates to a cutting seedling raising method of diosminthus scutellaria. Background technique [0002] Dioscorea Zingiberensis C.H.Wright, also known as turmeric and firehead root (Sichuan, Hubei), is a perennial herbaceous vine plant belonging to the genus Dioscorea in the family Dioscorea. It is an endemic species in my country and is distributed in Henan, Hubei, Hunan, Shaanxi, Gansu, and Sichuan and so on. The content of diosgenin (commonly known as saponin) in the rhizome of Dioscorea scutellaria is 1.1% to 16.15%, which is one of the main types of diosgenin plants extracted from diosgenin in my country (Xiao Wei, 2004). [0003] At present, the seedling propagation of Dioscorea scutellaria mainly adopts two methods of asexual propagation and sexual propagation; in asexual propagation, conventionally carry out asexual propagation with rhizomes, and a rapid ...
