Description
Technical field
The present invention relates to field of plant reproduction, more particularly to a kind of rich root method for culturing seedlings of toon rapid cuttage.
Background technology
Toon (Toona ciliata), is Meliaceae Cedrela fallen leaves or half fallen leaves megaphanerophyte, " China is enjoyed in the world
The good reputation of mahogany ".Rapidly, form is satisfactorily logical straight, and material is excellent for toon growth, is the preferable fast-growing treasure for cultivating large diameter material
Your commerical tree species, is also excellent furniture woodses seeds.Toon is national II grade of Top-rated protected wild plants, and NATURAL DISTRIBUTION is in good fortune
Build, Hunan, Guangdong, Guangxi, the provinces and regions such as Sichuan and Yunnan, but because natural renovation is difficult, natural resources is fewer and fewer.Toon is certainly
It is no lack of dry-shaped straight, satisfactory select tree in right resource, current toon breeding mainly passes through seminal propagation, it is impossible to preserve select tree
Good characteristic, and seed is very limited；Using the also prematurity of the current technology of the method for tissue cultures；It can be protected using cutting propagation
The good characteristic of select tree, but cuttings 2-3 bud of band prepared by current common cottage method are deposited, reproductive efficiency is low, unfavorable
In the clone nursery stock for quickly breeding select tree.The present invention is carried out using the rich root seedling-raising technique of single-bud cuttage using soilless substrate
Cuttage, then be transplanted in soil matrix matter and cultivated, the problem of Clones of Plus Trees is quickly bred can be solved, and turn out richness
Offspring is to improve the surrival rate of afforestation, and the quick breeding for toon fine individual plant is significant with promoting.At present, there is not yet
The report of the rich offspring of Clones of Plus Trees is cultivated with toon single-bud cuttage.
Currently available technology has 2 kinds：
Toon seeding and seedling raising technology：Pluck when capsule is brown but when not ftractureing, after seed collection, airing threshing is gone
It is fitted into after miscellaneous in hermetic bag, puts cryopreservation in 5 DEG C or so of refrigerator.General spring is sowed, and spring sowing is preferably entered in mid-March
OK.Fine site preparation is first carried out before sowing, composite fertilizer 30-40kg/ mus is applied, 25kg/ mus of phosphate fertilizer makees base manure, and is made into wide 1.2-
1.5m turtleback shape seedbed.Shallow ridges drilling is opened during sowing, bar sows 1kg/ mus away from 20-25cm, covers fine earth thickness 0.5cm, with
It is degree to lose seed, upper with long covering, treats that seedling is largely unearthed and removes lid grass.Seedling stage be mainly water and fertilizer management, pest and disease damage prevent
Control and weed with a hoe.Timely weeding after emerging；Rainy season will exclude ditch internal water accumulation in time, and arid season is irrigated in time；Fertilising
On a small quantity repeatedly typically to be advisable with annual 3 times, the 1st inferior to 2.5-3kg/ mu of 7 Yue Chushi composite fertilizers, the 2nd inferior to July by the end of June
4-5kg/ mus of bottom application composite fertilizer, the 3rd applies composite fertilizer 9-10kg/ mus inferior to mid-August.Seedling stage will prevent damping-off, stem rot etc.
Occur, can be prevented and treated with 300-400 times of liquid of 300-400 times of liquid of 50% carbendazim or 50% thiophanate.Enter in the ranks during height of seedling 8-10cm
Seedling, to ensure rational seedling art density, the other transplant of seedling of removal.Produce 20,000 plants/acre of seedling amount.
The defect of this technology is：
1) toon popularization and afforestation needs substantial amounts of breeding nursery stock, and domestic toon not yet sets up breeding breeding garden at present,
And the seed that toon seeding and seedling raising is used on the market is substantially the seed arbitrarily gathered, seed collecting elite stand is not selected,
The seed of collection is very different, and the nursery stock quality cultivated is not ensured.
2) small part grows prominent, tree-like good select tree in toon natural resources, and seed amount is very limited, and sowing is educated
The nursery stock quantity that seedling is cultivated is limited, it is impossible to meet the demand of a large amount of breeding nursery stocks of needs in production.
3) the toon seedling root that seeding and seedling raising is cultivated is based on main root, and lateral root is less, and the surrival rate of afforestation is low.
Toon cuttage raise seedling technique：
Enriched from the development of tree body middle and upper part, no disease and pests harm gives birth to coppice shoot then, in the morning clip, by the semi-lignified cut
Spray spreads frescade and notes moisturizing.Cutting is cut into 6cm or so length, and cutting two ends are cut into flat nick.It is required that keeping notch
Position is neat and tangent plane is small.The cutting sheared is bundled into bundle and is totally immersed into 700 times of carbendazols after sterilization 10min, and semi-lignified is tender
Branch is with clip with cuttage, and the timely high 1.7-1.9m shade nets of built shelter from heat or light cooling after cuttage, and shade net can be spread after the 100d that shelters from heat or light.
In moisturizing of watering in time after inserting, insert and all poured once permeable again with 700 times of carbendazols diseases preventions of sprinkling after a ridge again.It
Build high 40-60cm bow member in slotting machine with bamboo chip afterwards, moisturizing is covered with all-transparent agricultural plastic film, with soil by slotting machine four
All films are pressed and sealed.Note inspection in time, seedbed epiphragma has breakage if finding, to subsidize damaged portion with transparent adhesive tape in time close
Seal moisturizing.After cuttage in running check cutting bed situations such as humidity, if matrix is dried, it should select to open in the morning or during the dusk
Seedbed side film water spray, while spray (700 times of the carbendazim aqueous solution or carbendazol wettable powder liquid and flolimat breast
Oily 700 times of aqueous solution) diseases prevention insect prevention and seal mulch film in time, take root when nursery stock, foliation after, with reference to water spray progress foliage-spray
GGR6 liquid (600mg/l) and foliar fertilizer (change 0.3% urea and change 0.2% potassium dihydrogen phosphate solution).120d takes off film after cuttage
(should be noted that during high temperature aeration-cooling), first opens arch membrane two ends when taking off film, allow after its gravity-flow ventilation 4-6d, then take off film.
