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
The invention belongs to plant seedling vegetative propagation technique field, relate to a kind of dioscorea zingiberensis wright cuttage and seedling culture method.
Background technology
Dioscorea zingiberensis wright (Dioscorea Zingiberensis C.H.Wright) another name yellow ginger, duration and degree of heating root (Sichuan, Hubei), the herbaceous perennial vine plant, belong to the Dioscoreaceae Dioscorea, be China endemic species, be distributed in ground such as Henan, Hubei, Hunan, Shaanxi, Gansu, Sichuan.The content of diosgenin in the dioscorea zingiberensis wright root-like stock (disogenin) (being commonly called as saponin) is 1.1%～16.15%, is one of the main yam type extracted of the present diosgenin of China (Xiao Wei, 2004).
At present, the dioscorea zingiberensis wright sapling multiplication mainly adopts vegetative propagation and two kinds of methods of sexual propagation; In vegetative propagation, conventional carry out vegetative propagation and based on rapid breeding method of plant (Meng Ling, 2000 of plant tissue culture technique with root-like stock; Zhao Meng, 2007), do not help the report that branch carries out cottage propagation as yet; Have a very big shortcoming with root-like stock as propagating materials, need take exactly a large amount of ginger pieces as cultivation with kind, 0.07 hectare need be planted stem two, 300 jin, invests very greatly, and cost is higher; Micropropagation of plants is used for laboratory research at present because cost is higher morely; And dioscorea zingiberensis wright sexual propagation (promptly by the seminal propagation) production cycle is long than vegetative propagation, and general vegetative growth year can be gathered in the crops in 2～3 years, and the sexual propagation subterranean stem need just can be gathered in the crops (Xiao Wei, 2004 in 3～4 years; Pay gorgeous magnificent 2002).
The advantage of carrying out cottage propagation comprises that mainly the required cutting of breeding can obtain at a low price or gratuitously, and stable source is arranged, and does not influence the harvest of cultivation commodity ginger piece simultaneously substantially; In the measure of dioscorea zingiberensis wright high-yield culturing, climing since the mid or late June control of pinching, erase the top tip during the promptly climing long 2m left and right sides, suppress overnutrition growth surely by beating, promote phototrophy to the rhizome accumulation to obtain high yield (the poplar love people 2002).
By literature search, do not see the open report identical with the present invention.
Close patent of invention has 4: the vegetative propagation (02115808.8) of (1) yellow ginger, the vegetative propagation object of this invention is that yellow ginger is a dioscorea zingiberensis wright, but the propagating materials that uses is the yellow ginger root-like stock, different with the present invention, its purpose is " the wild family that changes " that realizes yellow ginger, and is also also different with the present invention; (2) quick propagating method for dioscorea seedling through cuttage (200710020593), it is invented at congener Chinese yam (Dioscorea polystachya), and different with the present invention, the cuttage material is the top tender stem segments in addition, needs stream treatment, no survival rate data; (3) a kind of cuttage breeding method of Dioscorea camposita (200610163809.1), the vegetative propagation object of this invention is a Dioscorea camposita, different with the present invention, the plugged ear of this invention needs to handle through the root-inducing powder aqueous solution or pulvis, and the cuttage seedbed is handled with 800 times of liquid pourings of fungicide carbendazim; (4) Dioscorea camposita cuttage breeding method (201110041470.9), the vegetative propagation object of this invention is a Dioscorea camposita, and is different with the present invention, the plugged ear of this invention needs to handle through root-growing agent and bactericide, and to the sterilization of cuttage seedbed.
Summary of the invention
In order to overcome defective of the prior art, solve the problems of the technologies described above, the invention provides a kind of simple operation, dioscorea zingiberensis wright cuttage and seedling culture method with low cost.
Its technical scheme is as follows:
A kind of dioscorea zingiberensis wright cuttage and seedling culture method may further comprise the steps:
(1) adopt branch: mid or late June began to mid or late September, and climing length is cut with top for 2 meters, and clip places water, deposits in the cool;
(2) lopping: with the branch of clip be trimmed to have 1～2 piece of intact leaf and at least one joint branch as cutting, the cane diameter of transplanting a cutting is 1～2 millimeter, length is 1～8 centimetre;
(3) cuttage: insert in the moist cutting medium the cutting level is horizontal, branch is imbedded 1～6 centimetre of matrix, and blade is exposed in the air, and cutting density is advisable with the blade non-overlapping copies;
(4) insert the back management: temperature remains on 25 ℃～33 ℃ during cuttage, and humidity sprays the plant growth regulating substance solution of hestening rooting, bulb formation 30%～40% in good time during managing and protecting;
(5) transplant: the dioscorea zingiberensis wright of cuttage is transplanted a cutting and is formed adventive root and new branch after one or two month, and planting percent reaches more than 95%, reaches the transplanting requirement.
Further preferred, adopt branch in the described step (1) and utilize part below 2 meters.
Further preferred, to transplant a cutting in the described step (3) and adopt perpendicular inserting, the joint of transplanting a cutting during perpendicular the inserting matrix of submerging, blade is exposed in the air.
