Technical field
The present invention relates to one and overcome the incompatible method of litchi graft, belong to fruit tree cultivation technical field.
Background technology
Fruit-tree grafting compatibility refers to that fruit tree stock and scion can normally be healed after grafting, the ability of growth and division result.Whether affine grafting is, by the similitude of the hereditary capacity of stock, scion, physiological function, biochemical reaction and internal organizational structure etc. and the impact of adaptive capacity mutually, also relevant with weather conditions and virus infection.The size of grafting affinity directly affects grafting survival, the growing way of graft, resistance and life-span and yield and quality etc.
Lichee is the tropical and subtropical zone characteristic fruit tree originating in south China, plant with a long history, in recent years, produce due to lichee and there is the reasons such as kind is aging, fruit quality is poor, the maturing stage is concentrated, mismanagement, cause lichee market price state at a low ebb, therefore, Litchi Varieties structural adjustment is very urgent, and large tree high-grafting also just becomes inevitable choice.
Nandao seedless litchi is the late-maturing breeding of seedless litchi that current lichee market is popular, its fruit subcircular, single fruit weight about 33 grams, pericarp red zone is green, pulp milky, soft sliding succulence, soluble solid 14.5%, taste is fresh and sweet, seedless, edible rate 87.5%, product are of fine quality, in Jimei District, Xiamen, mid or late July in maturing stage, high financial profit, market price 15-20 unit per jin, yielding ability is good, deeply welcomes by orchard worker.
Crow leaf lichee is the ancient landrace that the south subtropics regions following the line of the sea such as Fujian, Guangdong, Guangxi, Taiwan are extensively planted, and Cultural distribution is very wide, the askew heart of its fruit, single fruit weight 19.6 grams, pericarp aubergine is thinner, pulp wax, the soft cunning of meat is careful, and fruit juice is medium many, soluble solid 17.5%, local flavor is fresh and sweet, micro-perfume (or spice), edible rate 75.4%, quality is first-class, and seed is greatly medium, occasionally there is burnt core, mid or late June in maturing stage, ripe Litchi Varieties in genus.This kind is large in market share amount, and market price 1.5-2.5 unit per jin, economic benefit is low, and this kind is just progressively by market at present.
The black old orchard of leaf lichee (high pressure is planted by seed) of a life in 20 years, black leaf lichee is needed to be replaced with lichee breeding " Austronesia is seedless ", but on lichee is produced, large cloves lichee and black leaf litchi graft affine, large cloves lichee and Nandao seedless litchi grafting affine, and there is Incompatibility phenomenon in Nandao seedless litchi and black leaf lichee, therefore, in order to enable Nandao seedless litchi successfully grafting on the large tree of black leaf lichee, we must solve Nandao seedless litchi and black leaf litchi graft this difficult problem not affine.
Summary of the invention
The object of the present invention is to provide one to overcome the incompatible method of litchi graft, enable Nandao seedless litchi successfully grafting on the large tree of black leaf lichee, solve Nandao seedless litchi and black leaf litchi graft this difficult problem not affine.
For achieving the above object, the present invention adopts following technical scheme:
The large tree of black leaf lichee is carried out heavy pruning, retract to major branch, adopt cut-grafting method, by Nandao seedless litchi (fringe) first grafting in vitro large cloves lichee (interstock) brachyplast, fixing with plastic film wrapping, then again by the grafting of large for this section cloves lichee (interstock) brachyplast on the major branch of the large tree of black leaf lichee (stock), fixing with plastic film wrapping, complete in twice grafting at one time.This section of large cloves lichee brachyplast serves the connection function of bridge between Nandao seedless litchi and black leaf lichee.
Described large cloves lichee brachyplast rugosity is 0.7-1.0cm, length 5-6cm, stays 1-2 bud.
Described Nandao seedless litchi is Nandao seedless litchi scion.
Thisly to be combined as: [Nandao seedless litchi (fringe)+large cloves lichee (interstock)]+black leaf lichee (anvil) (as shown in Figure 1, Figure 2), grafting rear port can normally heal, after more than 30 day, Nandao seedless litchi (fringe), large cloves lichee (interstock) have all grown sprouting, erase the sprouting that large cloves lichee (interstock) grows, it is 93.5 % that its height is connected into motility rate, affine branch rate is 100%, within 2nd year, Nandao seedless litchi shows good ability of yielding positive results, the one older tip 4 times, Shoot growth is grown normal, and grow fine (as Fig. 3, Fig. 4).
The invention has the advantages that: the problem 1, solving lichee anvil fringe Incompatibility; 2, the economic benefit in grafting orchard is manifested quickly; 3, contribute to saving lichee production cost, increase economic efficiency.
