Abstract

The invention relates to a late-maturing short grapefruit tree cultivating method. The late-maturing short grapefruit tree cultivating method includes steps of grafting spring twigs of white pomelo with bud mutation onto a common grapefruit tree to cultivate twigs with bud mutation, then grafting to acid grapefruit seedlings to cultivate short grapefruit trees, planting the grapefruit trees in an orchard according to the density of 110-120 per mu, cutting off vertical upward boughs, and cultivating natural heart-shaped crown with three side boles. The late-maturing short grapefruit tree cultivating method has the advantages that operation is convenient, short trees with large fruits in high yield can be cultivated, maturing period is 1 or 2 months late, quality is excellent, taste is good, the trees are high in adaptability, fruits are long in storage life and can keep fresh without falling for six to twelve months and the like.

Description

The breeding method of a kind of late-maturing short grapefruit

Technical field

The present invention relates to the breeding method of a planting fruit-trees, specifically the breeding method of a kind of late-maturing short grapefruit.

Background technology

Cultivate the excellent shaddock tree of knot a kind of morning, high yield, the listing of late-maturing, anti-season, guarantee orchard worker's increasing both production and income, meet people and to live requirement.

Summary of the invention

The object of the present invention is to provide the breeding method of a kind of late-maturing short grapefruit, cultivate the excellent shaddock tree of knot a kind of morning, high yield, the listing of late-maturing, anti-season, guarantee orchard worker's increasing both production and income, meet people and to live requirement.

The object of the present invention is achieved like this:

The breeding method of late-maturing short grapefruit: (1), an annual spring, the spring tip grafting that the short and small and fruitful short Wanbai pummelo that there occurs bud mutation of selection tree crown is set, on common grapefruit, cultivates the branch that bud mutation occurs.(2), at the beginning of annual 1 month sow sour teak seed in ground, seedbed, cover plastic foil insulation vernalization, cultivate rootstock seedling.In March, the rootstock seedling growing to 5 ~ 10 centimeters is transplanted in nursery lot, line-spacing 15 ~ 20 centimeters, spacing in the rows 6 ~ 7 centimeters.(3), 8 ~ September then bud grafting is carried out, the branch spring tip that there occurs bud mutation cultivated is cut a bud grafting on the rootstock seedling of a strain acid shaddock, stock and scion are cut to forming layer, cutting angle is consistent, with the good grafting portion of plastic foil looping after alignment.(4), March of next year, the spring tip is cut anvil on grafting mouth top near bud grafting place 5 ~ 10mm, by the end of September, the grafting in nursery lot is moved to field planting before sprouting, by line-spacing 2 ~ 3 meters, spacing in the rows 1.5 ~ 2 meters, 110 ~ 220 plants/acre plant.(5), the pruning of bearing-age tree, cut off upright major branch, retain 3 side direction scaffold limbs, form natural open centre shape tree crown.In good time watering, fertilizing, deinsectization evil, the good short late shaddock orchard of management of protecting a forest.

The present invention has easy to operation; The short late teak height cultivated only 1 ~ 2 meter, happy shape tree crown, floor space is little, suitable dense planting, and can plant 110 ~ 220 strains in every mu of ground, every strain result 15 ~ 45, and fruit weighs 2 ~ 4 kilograms/, and single shaddock is than Wanbai pummelo weightening finish 30 ~ 80%, and output is high; Ripe before the Spring Festival, more late than the maturing stage of Wanbai pummelo 1 ~ 2 month, the seasonality having filled up fruit was rare; Best in quality, the micro-yellow of pulp, mouthfeel is good, tender and crisp succulence, aromatization slag, and contained soluble solid increases by 15 ~ 25% than Wanbai pummelo; Fruit tree strong adaptability, Plain fertile soil, headland, bare hills and mountains all can be planted; Fruit enduring store property is good, stores half a year more than with under plastic bag packaging normal temperature, and fresh preservation with branches can not fall fruit for 6 ~ 12 months.Suitable southern orchard worker plants application.

Embodiment:

Through long-term observation, in the Wanbai pummelo tree that the whole county is all, find that a strain tree crown is short and small, fruitful Wanbai pummelo tree every year.Cut its spring tip grafting 92 year spring on common large grapefruit, the branch that there occurs bud mutation of grafting on common grapefruit is cut grafting and cultivate short late shaddock seedling on sour shaddock anvil by 93 year spring, in September, 93 by short late shaddock transplantation of seedlings in different soil, by line-spacing 2 ~ 3 meters, spacing in the rows 1.5 ~ 2 meters, 110 ~ 220 meters/mu plant, water in good time, apply fertilizer, killing insect pest management.After 3 years, these short late shaddocks all try bow structure fruit.So far this batch of fruit tree height of tree about 2 meters, shorter about 1 meter than the Wanbai pummelo tree of planting the same year.15 shaddocks are produced in 97 annual strains, and calendar year 2001 is every strain result 31 on average, and nearly 45, result quantities increases year after year.Short late shaddock fruit is respectively at obtaining national high-quality shaddock class " golden cup prize " for twice in November, 99, November calendar year 2001.Just progressively plant to southern area of China Extend culture at present.

Claims

1. a breeding method for late-maturing short grapefruit, is characterized in that: (1), annual spring, and the spring tip grafting that the short and small and fruitful short Wanbai pummelo that there occurs bud mutation of selection tree crown is set, on common grapefruit, cultivates the branch that bud mutation occurs; (2), at the beginning of annual 1 month sow sour teak seed in ground, seedbed, cover plastic foil insulation vernalization, cultivate rootstock seedling; In March, the rootstock seedling growing to 5 ~ 10 centimeters is transplanted in nursery lot, line-spacing 15 ~ 20 centimeters, spacing in the rows 6 ~ 7 centimeters; (3) 8 ~ September, then carries out bud grafting, the branch spring tip that there occurs bud mutation cultivated is cut a bud grafting on a strain acid shaddock rootstock seedling, stock and scion are cut to shape layer by layer, cutting angle is consistent, uses the good grafting portion of plastic foil looping after alignment; (4), the March of next year, the spring tip cuts anvil on grafting mouth top near bud grafting place 5 ~ 10mm, by the end of September before sprouting, grafting in nursery lot is moved to field planting, by line-spacing 2 ~ 3 meters, spacing in the rows 1.5 ~ 2 meters, 110 ~ 220 plants/acre plant; (5), the pruning of bearing-age tree, cut off upright major branch, retain 3 side direction scaffold limbs, form natural open centre shape tree crown.
