Embodiment 1

[0023] (1) Preparation of the spring orchid inflorescence scion: Cut off a 5 cm long branch from the unopened orchid inflorescence branch, and then use a knife to cut off 2 / 5 of the scion obliquely through the center from a distance of 2.0 cm from the terminal bud.

[0024] (2) Hormone treatment of spring orchid inflorescence scion: use BA 0.1 mg L -1 +NAA 0.5 mg L -1 + 0.2% PVP (polyvinylpyrrolidone) solution of cotton to soak the cut surface of the scion for 1 minute.

[0025] (3) Preparation of spring orchid inflorescence rootstock: choose a section thicker than the scion as the inflorescence of the rootstock, remove the side flowers, and then cut off 3 / 5 from bottom to top with a knife. The length and width of the section of the rootstock should be the same as that of the scion unanimous.

[0026] (4) Grafting: Paste the cutting surface of the scion on the cutting surface of the rootstock, aligning up, down, left, and right.

[0027] (5) Handling of grafting interface: ...

Embodiment 2

[0032] (1) Storage of spring orchid inflorescences: Cut the unopened spring orchid inflorescences from the base of the inflorescences, wrap them in fresh-keeping bags, and store them in a refrigerator at 4°C for 3 days;

[0033] (2) Preparation of the spring orchid inflorescence scion: Cut off 5 cm long branchlets from the orchid inflorescence branch, and then use a knife to cut off 2 / 5 of the scion obliquely through the center from a distance of 1.5 cm from the terminal bud.

[0034] (3) Hormone treatment of spring orchid inflorescence scion: BA 0.1 mg·L -1 +NAA 0.5 mg L -1 +0.2% PVP (polyvinylpyrrolidone) solution of cotton soaked scion cut surface for 2 minutes.

[0035] (4) Preparation of inflorescence rootstock: as the inflorescence of the rootstock, select a section thicker than the scion, remove the side flowers, and then use a knife to cut off 3 / 5 from the bottom to the top. The length and width of the cut surface of the rootstock should be consistent with the cut sur...

Embodiment 3

[0042] (1) Storage of spring orchid inflorescences: cut unopened spring orchid inflorescences from the base of the inflorescences, wrap them in a fresh-keeping bag, and store them in a refrigerator at 4°C for 7 days;

[0043] (2) Preparation of inflorescence scion: cut 5 cm long twigs from the inflorescence branch of the orchid, and then use a knife to cut 2 / 5 of the scion obliquely through the center from a distance of 2.0 cm from the terminal bud.

[0044] (3) Hormone treatment of inflorescence scion: use 0.1 mg·L of imbibed BA -1 +NAA 0.5 mg L -1 + 0.2% PVP (polyvinylpyrrolidone) solution of cotton to soak the cut surface of the scion for 3 minutes.

[0045] (4) Preparation of inflorescence rootstock: as the inflorescence of the rootstock, select a section thicker than the scion, remove the side flowers, and then use a knife to cut off about 3 / 5 from bottom to top. The length and width of the section of the rootstock should be the same as that of the scion unanimous.

Abstract

The invention discloses a pith approach-grafting method for inflorescence of Cymbidium goeringii; the method comprises: (1) storing inflorescence; (2) preparing inflorescence scions; (3) treating the inflorescence scions with hormone; (4) preparing inflorescence stocks; (5) grafting; (6) treating graft unions; (7) managing water content of grafts; (8) managing lighting for the grafts. It is verified for the inflorescence of Cymbidium goeringii cultivated by the above method that grafting survival rate of Cymbidium goeringii reaches 100%, flowering rate reaches 100%, early flowering occurs on day 5 to day 9 after grafting, the flowering phase includes 25-35 days, the problem of adjusting the flowering phase of Cymbidium goeringii is solved, and the method has important actual application value.

Description

technical field [0001] The invention relates to a spring orchid inflorescence pith sticking method, which belongs to the field of grafting. Background technique [0002] The growth status of grafted plants depends on the scion, the ability to absorb nutrients depends on the rootstock, and the accumulation and distribution of nutrients depend on the joint effect of the two. The rootstock has a great influence on the growth and development of the graft. The rootstock regulates scion photosynthesis, yield, stress resistance, flowering period, floral aroma, and even flower type and color through changes in nutrients, hormones, signal transduction substances, and genetic materials. But there is no grafting technique applied to orchid cultivation at present. [0003] Chunlan ( Cymbidium goeringii (Reichb.F. ) Reichb.F.) is small in size, elegant and refined, with elegant flower color and quiet fragrance. It is known as "gentleman among flowers" and "the most fragrant in the wo...
