Abstract
The invention discloses a jackfruit branch topping and seedling growing method. Firstly, robust branches without diseases and pests are chosen from a jackfruit seed tree with excellent quality; secondly, girdling is conducted on the portion 15-20 cm away from the position where the branches are divaricated, 0.01%-0.06% ABT-1 solution is smeared on a girdling opening by one circle, the girdling position is bound with a wet matrix and wrapped in a thin film, and the two ends of the girdling position are bound through ropes; after branch topping is conducted for 5-25 days, diluted ethephon solution is added to a thin film bag; after branch topping is conducted for 40-50 days, a root system gradually grows from the girdling opening, and half-cutting treatment is conducted on the lower ends of the branches bound by the ropes; after half-cutting treatment is conducted for 20-30 days, the branches are cut off from the half-cut positions and subjected to heeling and transplanting. The jackfruit branch topping and seedling growing method is simple, operation is easy, the seedling growing period is short, the rooting percentage is high, the survival rate of transplanting is high, limitation of seasons is avoided, and the quality of grown seedlings is guaranteed at the same time.
Description
Technical field
The present invention relates to the seedling growing process field of plant, specifically relate to plant and refute the method that branch is grown seedlings.
Background technology
Jack fruit, has another name called jackfruit, artocarpus heterophyllus, belongs to tropical fruit (tree).In China Guangxi, Hainan, Guangdong, southeastern Yunnan and Fujian, there is cultivation in south, Chongqing.The nutritive value of jack fruit is very high, contains carbohydrate, sugar, protein, starch, vitamin, amino acid and the various mineral matters useful to human body.Its fruit is plump soft, and fresh and sweet good to eat, aromatic flavour, has the unique smell of kind of bubble gum, therefore be described as " tropical fruit (tree) queen.Meanwhile, jack fruit also has very high medical value, records the solution of quenching the thirst tired in Compendium of Material Medica, and the beneficial gas of being amusing, also has the effect of body-building and life-prolonging, is deeply subject to liking of consumers in general, and development prospect is wide.
The common asexual seedling breeding method of plant is grafting, cuttage and refutes a method.Close for pineapple, graft technology is bred unfavorable factor restrictions such as being subject to grafting season (generally can only select carry out spring) and growing-seedling period long (go out garden and need the 2-3 year from being seeded into asexual seedling).And cuttage technology is immature, survival rate is extremely low.Refute branch and grow seedlings can constantly obtain moisture and mineral nutrient from maternal plant before taking root, this both took root than the easier reality of cuttage, also unlike grafting, be subject to seasonal restrictions, and method was simple to operation, the cycle is short.But the conventional method rooting rate for jack fruit of refuting is high not enough, take root several less, so that transplant survival is not ideal enough.Due to above reason, the supply of jack fruit seedling is few, can not meet for a long time plantation family demand, has hindered the development of industry.
Summary of the invention
The present invention is directed to defect of the prior art, provide a kind of jack fruit to refute a seedling-cultivating method, after branch is processed, add an ethrel and carry out further growth-promoting root refuting, simultaneously adopt again semi-shear to carry out hardening on elite stand, thereby effectively improve rooting rate, transplanting survival rate.Be not subject to seasonal restrictions like this, reduce the impact on weather, geographical environment, the while has ensured again the quality of growing seedlings, and method is simple to operation, growing-seedling period is short.
Technical scheme of the present invention is as follows:
A kind of jack fruit is refuted a seedling-cultivating method, and it mainly comprises the steps:
(1) branch is chosen, and selects limb stalwartness, branch without damage by disease and insect on colory jack fruit elite stand; Conventionally selecting footpath is slightly the branch on the sunny side of 1.5 ~ 2.5cm.
(2) refuting branch processes, to the branch of choosing, carrying out band girdle apart from its branch bifurcated 15 ~ 20cm place, band girdle phloem width 2.0 ~ 4.0 cm, first smear band girdle mouth one circle with 0.01%～0.06% ABT-1 solution, tie up at band girdle place by moistening matrix, outside packs tightly with film and with rope binding two ends again; Described moistening matrix is the homogeneous mixture that wooden chaff, wormcast, baked wheaten cake soil mass ratio are 1:1:1 ~ 2.
(3) add ethrel, refuting after branch processing 15 ~ 25d, the ethephon solution after dilution is added in film bag; Described ethephon solution is by 6000 ~ 10000 times of 40 % ethrel dilutions; The addition of ethephon solution is 30-70 ml.
This step, to hestening rooting, improves follow-up survival rate very crucial: jack fruit rooting process be divided into induction period, in early days make a start the stage, make a start 4 stages such as later stage and Growth and Differentiation stage.First and second stage of taking root is taking cell division as feature, now needs higher auxin concentration, and mark is that IAA (heteroauxin) oxidase and peroxidase activity are low.And phase III later stage that to be root make a start needs lower auxin concentration.Taking to inject certain density ethephon solution for the physio-biochemical characteristics in this stage, to improve IAA oxidase and peroxidase activity, reduce Endogenous auxin level, is the effective way of hestening rooting.
(4) branch semi-shear, is refuting 40 ~ 50 d after branch processing, and band girdle mouth place grows root system gradually, carries out the processing of branch semi-shear in rope binding place lower end;
The branch semi-shear of described step (4) is that branch cane is cut off to half, gos deep into xylem, but branch still keeps being connected with parent.This step is more crucial, and the processing of branch semi-shear can improve the survival rate of follow-up lower ground hardening.Conventionally plant was refuted after the branch processing 2-3 month, just can direct shearing transplant hardening, but for jack fruit, this method can cause follow-up hardening survival rate on the low side.Because it is very large that unexpected like this shearing is transplanted plant injury, the hardening laundering period is long, poor growth; And the present invention carries out the processing of branch semi-shear after 40 d～50 d refuting branch, the nutrient both having hindered on part branch is back to elite stand tree root, and the nutrient that affects again root is upwards carried, and reaches the object of hardening in advance, thereby improves transplanting success.
(5) heel in transplanting, after branch semi-shear 20 ~ 30d, cut at its semi-shear place, heel in transplanting.This step is also the hardening stage, only needs within 2-3 month, can go out garden.
Adopt a seedling-cultivating method of refuting of the present invention, can carry out asexual multiplication seedling to jack fruit in different seasons, have and can keep the good hereditary capacity of jack fruit kind, and technology simply, easily operation.Branch rooting rate reaches more than 95%, transplants after hardening, and survival rate can reach more than 99%.
The present invention has the following advantages compared with the prior art:
(1) shorten the time of breeding jack fruit seedling, breeding jack fruit seedling according to conventional method needs 1.5 ~ 2 years, and with originally refuting a seedling growing process, effect in about 6 months can go out garden.
(2) seedling-cultivating method of the present invention, refuting injection ethrel after branch, can improve greatly and refute the rooting rate of a seedling and shorten the garden time, improves greatly breeding efficiency.Adopt in this way, rooting rate can reach more than 95%.
(3) seedling-cultivating method of the present invention adopts the processing of branch semi-shear, has realized hardening on parent, can improve transplanting survival rate, and fast, transplanting survival rate has reached more than 99% in growth; And it is lower generally to refute a technology survival rate, because lack parent hardening link, otch damage is larger, poor growth.
