Embodiment 1

[0031] A kind of pitaya grafting method, comprises the following steps:

[0032] (1) Rootstock cultivation, in October, the variety Tianchi belongs to "Guizhen No. 1" was used as a rootstock, and 200 plants were cultivated. Get the rootstock variety stem section 30-60cm that is eight mature (and green, harder, full, healthy and disease-free stem section), cut the base edge of the stem section into a wedge shape to expose the vascular bundle about 1.0cm, and then remove the thorns on the stock. All the bases were castrated, then soaked in 600 times carbendazim solution for 1 minute, and dried for 24 hours for later use; using coconut bran as the culture substrate, the rootstock cuttings were placed in the seedling cultivation substrate, and placed in a healing cultivation medium with a shading rate of about 50%. The water rate is maintained at 60-80%, and the daily average air temperature is 20-30°C for 45 days of cultivation. During this period, the water of 0.5% compound fert...

Embodiment 2

[0039] A kind of pitaya grafting method, comprises the following steps:

[0040] (1) Rootstock cultivation, in April, the amount of Tianchi belongs to the "Vietnamese white meat" variety is used as a rootstock, and 200 plants are cultivated, and 30 stems of the rootstock variety that are eight mature (and green, hard, plump, healthy and disease-free) are taken. -60cm, cut the edge of the base of the stem segment into a wedge shape to expose the vascular bundle about 1.0cm, then castrate all the thorns on the rootstock, then soak it in 600 times carbendazim solution for 1 minute, and let it dry for 24 hours for later use; use coconut peat As a culture substrate, the rootstock cuttings are placed in the seedling culture substrate, and placed in an environment where the shading rate of the healing culture is about 50%, the field water holding rate of the substrate is maintained at 60-80%, and the average daily temperature is 20-30°C for 30 days. Spray the compound fertilizer (15-...

Embodiment 3

[0047] A kind of pitaya grafting method, comprises the following steps:

[0048] (1) Rootstock cultivation, in August, use the "Black Dragon Fruit" variety of the genus Serpentis as a rootstock, cultivate 200 plants, and take eight mature (and green, hard, plump, healthy and disease-free stems) stems of rootstock varieties 30-60cm, cut the edge of the base of the stem segment into a wedge shape to expose the vascular bundle about 1.0cm, then castrate all the thorns on the rootstock, then soak it in 600 times carbendazim solution for 1 minute, and let it dry for 24 hours for later use; The bran is used as the culture substrate, and the rootstock cuttings are placed in the seedling cultivation substrate, and placed in an environment with a shading rate of about 50% for healing culture, a field water holding rate of the substrate of 60-80%, and an average daily temperature of 20-30°C for 60 days. Spray concentration every 7 days is the compound fertilizer water of 0.5%, until roo...

Abstract

The invention discloses a dragon-fruit grafting method. The dragon-fruit grafting method includes the following steps of (1) stock cultivating, wherein a cultivation-matured hylocereus or selenicereusvarietal plant is taken and serves as a stock, thorn bases on the stock are completely castrated off, and then cultivation is carried out; (2) stock treating, wherein a part of fleshy parts are cut on an edge which is a section of distance away from the top of the stock along the edge of a central vascular bundle, and a wedge-shaped or right-angle carved notch is formed; (3) scion treating, wherein a target-variety dragon-fruit branch is taken and cut into a single-thorn-base scion along the edge of the central vascular bundle; (4) grafting, wherein the single-thorn-base bud scion is put at the wedge-shaped or right-angle carved notch of the stock, jointing treatment and fixing are carried out, and an unhealed grafted seedling is obtained; (5) nursery stock healing cultivating. Accordingto the dragon-fruit nursery stocks grafted with the method, operation is easy, healing of a grafting opening is good, and the survival rate of the nursery stocks after grafting is 98% or above. The nursery stocks after grafting is standardized and coincident, a few bud-picking workers are wasted in cultivation and management after nursery stock planting, and the growth speed of the nursery stocksis higher.

Description

technical field [0001] The invention relates to the field of pitaya cultivation, in particular to a pitaya grafting method. Background technique [0002] Dragon fruit is a new subtropical fruit tree and a fashionable health-care fruit. In recent years, the demand in the domestic market has been continuously expanding, and the cultivated area is increasing rapidly. The mainstream development direction of dragon fruit cultivation and production is gradually developing from scattered planting, extensive and semi-extensive management to large-scale, intensive and high-quality (high-quality) cultivation. [0003] At present, the dragon fruit nursery stock of industrial application mainly is (1) cuttage seedling, promptly carries out the cutting propagation method with stem section and cultivates; A section (part) of the scion plant body is joined to the rootstock, placed in a suitable environment for healing and cultivation for a period of time, and finally the finished seedling...
