A kind of method for culturing seedlings of tea tree
Technical field
The present invention relates to the cutting propagation field of tea tree, more particularly to the method for culturing seedlings of tea tree, and for most wood
This plant all has directive significance.
Background technology
Tea tree is perennial industrial crops, its propagation method is divided into two kinds of generative propagation and vegetative propagation.Wherein, it is sexual numerous
It is to be bred tea tree seed sowing to grow, its advantage is that accommodative ability of environment is strong, seedling cost is low, but the drawback is that is planted
Economic characters mix between strain, and growth differences are big, and breeding time is inconsistent, inconvenience management, the especially low tea tree product of some setting percentages
Kind is difficult to use seminal propagation.Since vegetative propagation can keep the feature of breeding, characters of progenies uniformity is high, is conducive to tea place
Management, enjoys people to pay close attention in recent years, but asexual reproduction method traditional at present is in the rooting efficiency of tea tree and survival rate side
Face is undesirable.
For Water culture reproduction technique as one kind in asexual reproduction method, it is to make matrix with water, utilizes in vitro plant
The regenerability of histoorgan, makes it bud into the nursery side of an Individual plant body through artificial culture under certain condition
Method.But traditional Water culture propagation method is influenced be subject to factors such as temperature, water quality, illumination, generally existing root of hair speed
The defects such as slowly, survival rate is low.If Chinese Patent Application No. is a kind of 201310110582.4 water planting-earth culture skewers for disclosing tea tree
Fast seedling-cultivating method is inserted, its process route is as follows:Greenhouse, solarium prepare, and prepare nutrient solution, adopt fringe, cut fringe, the disinfection of cuttings clip
Sterilizing, HORMONE TREATMENT, greenhouse cuttage, Greenhouse Water Culture, prepares nutrient soil pot, turns seedling cuttage, and solarium's earth culture is taken root, and cuttings is into tea
Seedling, hardening to seedling.Although above-mentioned patent is by the way that water planting temperature control in greenhouse at 25~30 DEG C, is promoted to a certain extent
Take root, but easily lead to the tender shoots of ullage, tender leaf at such a temperature because dehydration is withered very much soon.
In addition, it must be semi-lignified branch that traditional cutting propagation, which requires cuttage fringe, therefore also needed to before cuttage by branch
Non-woodization part on the tip is wiped out, and directly reduces the utilization rate of branch.In addition, traditional cutting propagation is subject to the shadow in time more
Ring, be typically chosen the convenient time progress of spring and summer temperature, also limit the development of tea tree nursery to a certain extent.
The content of the invention
In consideration of it, the object of the present invention is to provide a kind of method for culturing seedlings of tea tree, this method limits from the time, can be one
The four seasons in year complete cuttage, which solve traditional tea tree method for culturing seedlings and are difficult to be suitable for non-semi-lignified branch, and root of hair speed
