Abstract
The invention relates to a technology for propagating an aleurites moluccana seedling by high-altitude layering. According to the technology, an operating method comprises the following steps of: selecting branches of which the sizes are similar and the growth conditions are excellent from the aleurites moluccana tree which has more than 4 age from March to October in every year; performing girdling on the stem bases of the selected branches, wherein the width is about 2 to 4 centimeters, and a cortex layer and a cambium are scraped completely; coating a growth regulator with appropriate concentration at the upper ends of incisions; making a wet matrix into a mud pie, covering wounds with the mud pie, wrapping the outside of the mud pie by using a plastic film, and binding by using a packing rope; and checking the humidity of the mud pie during layering rooting, and when the humidity is low, replenishing moisture by an injection method to keep the humidity of soil, wherein after the girdling is performed, roots are grown at the wounds a month later; and cutting the layering for transplant when a large quantity of root systems are formed two or three month later.
Description
Technical field
The present invention relates to the propagation technique method of a plant species, be the method for candlenut tree tree asexual multiplication seedling.
Background technology
Candlenut tree (Aleurites moluccana) originates from the torrid zone and subtropical zone, is the tall and big aiphyllium of wide leaf, and its kernel fat content is up to 64%-68%, and protein content is 21.6%.Candlenut tree kernel grease is the quality raw materials of production biodiesel, and the resulting cake protein matter content in oil expression back can be processed as the concentrated feed of high-quality or the compoiste fertilizer that high-efficiency high-quality is produced in direct fermentation up to 40%～50% after detoxification treatment.Candlenut tree kind shell heavily fortified point is thick, weight account for seed heavy about 60%, contain oil content, calorific value is up to 4370 kilocalories/kg, can do fuel and substitute coal.Therefore, candlenut tree is to have the high efficient energy sources type forest that important development is utilized prospect.The tradition breeding of candlenut tree is to adopt the sexual propagation mode; Promptly utilize the planting seed seedling raising and transplanting; Because the candlenut tree seed dormancy phase is long, germination rate is low, it is irregular to emerge; Seedling raise period is long, from be seeded into outplanting, transplanting needs the 2-3 year, and seedling grow irregular, yield level is widely different.In addition, candlenut tree tree seedling plant phase of bearing fruit for the first time is long, needs 5-8, and these problems are bottlenecks that restriction candlenut tree tree industrialization plantation develops.
Summary of the invention
Purpose of design: be intended to overcome the defective of seminal propagation technology, a kind of asexual multiplication seedling, plant strain growth neat and consistent be provided, the high candlenut tree height of tree pneumatics bar propagation method of output early of bearing fruit.
Design: utilize the overhead layering propagation technique candlenut tree tree to be carried out asexual multiplication seedling in different seasonal; Have and to keep the good hereditary capacity of candlenut tree tree kind; And technology is simple, operation easily, cost are low; Advantages such as survival rate is high, and is can early flowering solid are the candlenut tree seeds seedling important technology methods of breeding fast.
Technical scheme: a kind of technology of candlenut tree overhead layering breeding and seedling relates to a kind of technology of cultivating good candlenut tree seedling through vegetative propagation technique.Carry out according to the following steps:, on the tree of the candlenut tree more than 4 ages, select the branch that size is close, upgrowth situation is good in the 3-10 month in every year.Branch base portion selected carries out band girdle, and the about 2～4cm of width notes scraping cortex and cambium; Smear processing in the otch upper end with the growth regulator of suitable concentration; The moistening matrix that is modulated into dry rice straw and loam is again made walk parcel wound, and the outside packs tightly walk with plastic foil, and good with the packing rope colligation; Inspection walk humidity during press strip is taken root, humidity are crossed and are adopted injection to keep the skin wet to keep soil moisture when hanging down.Girdling was handled after 1 month, and the wound begins to take root, and can downcut press strip when forming a large amount of root system after 2-3 month and transplant.
The present invention compares with background technology; Its characteristics have: the one, and the branch that utilizes the 2-3 on the growth candlenut tree plant to give birth to carries out overhead layering; Elite stand enterprising field headquarters health long 70-100 days, the girdling wound formed root system, obtained healthy and strong candlenut tree seedling; Its branch rooting rate is 75.0%-91.7%, and transplanting survival rate reaches more than 99.5%; The 2nd, overhead layering breeding candlenut tree seedling can keep good genetic character such as its fruit yield, kernel fat content and disease and insect resistance; The 3rd, the overhead layering breeding and seedling is technological simple, processing ease, and survival rate is high, the seedling growth neat and consistent, survival rate is high, and the time is short, grows seedlings then to go out the garden transplanting then.
Embodiment
Embodiment 1: mid-March, on the candlenut tree tree in 4 ages, 60 in the healthy and strong branch of selection 2-3 life, anosis no insect pest carries out overhead layering.It is wide to carry out girdling 2-4cm at the branch base portion of choosing, and the degree of depth is destroyed the cambium tissue fully to xylem; Coat the NAA solution of 200mg/L in the wound, make walk (long 7-8cm, diameter 5-6cm with moistening matrix (the mixed stack retting that adds 1 kilogram of straw by per 15 kilograms of loam); Heavily about 0.25kg) parcel wound, the outside packs tightly walk with plastic film (long 30cm, wide 20cm); Use the good two ends of packing rope colligation again, see accompanying drawing 1.Check the humidity of 1 walk during taking root weekly, cross when low, adopt injection to keep the skin wet, keep ground moistening like walk soil moisture.Girdling is handled after 1 month and is begun to take root, and a large amount of root systems are sprouted and grown about 1 first quarter moon, downcuts the branch of taking root during the long 4.8-6.4cm of 2-3 month root and transplants plantation, and the individual plant maximum is taken root for counting and reached 26, and the longest root reaches 6.4cm, sees accompanying drawing 2.The branch rooting rate is 75%, and transplanting survival rate reaches 100%.
