The invention discloses a method for cutting a twig of catalpa bungei. The method comprises the following steps: selecting the twig, preparing a soak solution, preparing a matrix, selecting a cutting period, treating a cutting pool, and carrying out management after cutting. The rooting rate and survival rate of a tender sprout, cut by adopting the method disclosed by the invention, of the catalpa bungei are high, the seedling emergence time is short, the growth vigor in a later period is good, and economic benefits of growers are greatly improved.
Description
Technical field
The present invention relates to high quality tree species breed field, specifically a kind of method of Chinese catalpa epicormic branch cuttage.
Background technology
There are many difficulties always in the nursery aspect of Chinese catalpa, and provenance test, breed breeding, seedling-raising technique, cultivation management
The research such as pattern is less, in terms of improving cutting propagation survival rate also no preferable effect so that Chinese catalpa afforestation is not almost had with Seedling
There is source, spread is highly limited.Research Chinese catalpa seedling-raising technique, improve its survival rate of seedling and then seem abnormal heavy
Will.For from propagation method, because Chinese catalpa spends incompatibility certainly, solid rareness, Seedling propagation is difficult, and propagation by grafiting is again easily
The rough sledding such as incompatibility, senilism occur.Current improved seeds rely primarily on grafting expanding propagation, but graft seedling growth needs to train
Educate stock, growing-seedling period extends, incompatibility, the late growing stage of impact nursery stock easily in grafting simultaneously, breeds skill
Art backwardness becomes the technical bottleneck limiting Chinese catalpa popularization.Break through the technical barrier of catalpa bungei vegetative propagation, have extremely important existing
Sincere justice.And cutting propagation is because it has, and simple to operate, seedling growth is fast, breeding coefficient is high, low cost and other advantages, it is increasingly subject to
The attention of people.
Cutting propagation is the totipotency using plant cell, relies on and cuts off the nutrition such as the root getting off, stem, leaf on maternal plant
Body, develops under certain conditions again for a complete new plant.Cuttage can be divided into by the difference of its chosen material firmly
Branch cuttage, epicormic branch cuttage, the form such as root is inserted, bud cutting and leaf are inserted.Wherein, the twig skewer with the twig of plant semi-lignified as material
Simple to operate, seedling growth is fast, breeding coefficient is high, low cost and other advantages because it has for slotting mode, is increasingly subject to the attention of people.
In addition the development of modern solar greenhouse technology is so that epicormic branch cuttage all can be carried out in the whole trophophase of plant.From this century
From the 40's, the synthetic with auxin and the utilization of artificial atomizing sticking device, the technology of cuttage root-taking is flown
Speed development, many seeds difficult to take root can successfully carry out amount reproduction.With the theoretical development of tissue culture, micro-propagation, childrenization and application,
The research of cutting propagation enters brand-new developmental stage.Particularly self-timing sprayer unit aborning commonly used,
Meet the strict demand to ambient moisture condition for the epicormic branch cuttage.Epicormic branch cuttage has been widely used for agricultural, gardening, flowers now
With fields such as Chinese herbal medicine.
Content of the invention
It is an object of the invention to provide a kind of method of Chinese catalpa epicormic branch cuttage, Chinese catalpa tender shoots rooting rate can be made and deposit
Motility rate improves, and seedling-growing time is short, and later stage growing way is good, greatly improves the economic benefit of Planting household.
The purpose of the present invention is achieved through the following technical solutions:
A kind of method of Chinese catalpa epicormic branch cuttage, comprises the following steps:
(1) twig selects: selects the twig material as Chinese catalpa cuttage for the primary lateral branches of raw Chinese catalpa then, the length of twig is 8-
10cm, rugosity is 0.3-0.5cm, after twig cutting is got off, at top down 2-3cm of twig, cuts a 1-3mm with little saw blade
Horizontal mouth;
(2) soak preparation: the Chinese catalpa twig that cutting is got off puts into immersion 10-15min in soak, and wherein soak is by following
The component composition of weight portion: 5-9 part salicylic acid, 7-11 part indole-3-acetic acid, 10-15 part tryptophan, 4-6 part 6-ba, 10-14
Part zeatin, 200-300 part water；
(3) substrate preparation: using the wood flour that becomes thoroughly decomposed of 1:1:1 ratio mixing, perlite, river sand as cutting medium, and to mixed base
Flos Jasmini Sambac extracting solution is added, wherein Flos Jasmini Sambac extracting solution and the mass ratio of mixed-matrix are 1:800-1000 in matter；
(4) cuttage period selects: chooses late Febuary to mid-March as the period of Chinese catalpa cuttage, in this period, Chinese catalpa is internal
Lay in abundant carbohydrate, source growth substance increasingly increases, be conducive to formation and the growth of Chinese catalpa adventitious root；
(5) cuttage pond is processed: cuttage pond is placed in natural lighting abundance, and the flat place of physical features, before cuttage, at the bottom of pond place mat
The thick broken rubble of 8-10cm, to increase breathability and the water penetration in cuttage pond, is then covered with the thick base of 25-30cm again above
Matter, installs a shower nozzle every 1.3-1.5m in cuttage pond, configures automatic intermittent spraying device；
(6) manage after inserting: after Chinese catalpa epicormic branch cuttage, at 25-30 DEG C, relative humidity controls in 80- daylight environment temperature control
90%；Night, temperature control was at 13-16 DEG C, and relative humidity controls in 60-70%, sprayed thiophanate-methyl, hundred bacterium every seven days
Clearly, the mixed liquor of Mancozeb and water, its volume ratio is, thiophanate-methyl: Bravo: Mancozeb: water=8:6:3:15, spray
The amount of spilling is 8-10kg/ mu；Cuttage was transplanted after 50-60 days.
After above-mentioned steps (3) mesostroma has been prepared, ultraviolet disinfection is carried out to it, uitraviolet intensity is 70 μ w/cm2, sterilization
Time is 30-50min.
Beneficial effect:
The method that the present invention adopts, improves rooting rate and the survival rate of Chinese catalpa, and effectively preventing Chinese catalpa tender shoots is in the cuttage phase
Between ill and hyperplastic situation occurs, seedling-growing time is short, and later stage growing way is good, greatly improves the economic effect of Planting household
Benefit.
