Problems solved by technology

As a tropical characteristic crop industry, Cai Diannan, Liu Guangze and others have studied the "Ylang-Ylang Fragrant Tree Dwarfing and Shaping Method" and "Ylang-Ylang Fragrant Dew Bud Grafting" and other technical methods, and have made some progress, but the production tree shape is still as high as 4 years after planting. ~15 meters, need frequent top pruning, resulting in difficulty in picking flowers, greatly increased labor costs, resulting in a gradual shrinking of the industry, currently only a small amount of distribution in Xishuangbanna, Baoshan and other places
[0005] In addition, the main flowering period of ylang-ylang is from May to August, and the flowering period is short, but the dwarf pruning needs to be carried out throughout the year, which is high in cost but small in profit
[0006] Therefore, dwarfing and year-round flowering of ylang ylang-ylang have always been key technical problems in planting and production, and there is no technical method suitable for the complete dwarfing of ylang-ylang planting and year-round flowering.

Embodiment 1

[0036] Embodiment 1: grafting method of the present invention

[0037] "Cananga odorata c.v.Mihua" was used as the rootstock, and "Canangaodorata c.v.Xiangshui" was used as the scion to carry out dwarf ylang-ylang grafting varieties.

[0038] Rootstock preparation: choose rootstock as 2-year-old bagged seedlings (approximately 20 centimeters in seedling bag diameter, about 20 centimeters in height, used to limit the growth of ylang ylang-ylang root system), plant height 1.8 meters, plant diameter at breast height about 2.6 centimeters, and healthy plants without disease and insect pests; Five days before grafting, the rootstock was cut 25 cm away from the soil surface for "primary cutting of the anvil", with an incision angle of about 45 degrees.

[0039] Scion preparation: select 2-year-old, strong, and non-mechanically damaged branches from the ylang-ylang tree to be grafted; keep the branch with a diameter of 0.6 cm, cut it into a 8.0 cm scion, and the scion has 3 bud point...

Embodiment 2

[0046] Embodiment 2: conventional dew bud budding method

[0047] "Cananga odorata c.v.Mihua" was used as the rootstock, and "Canangaodorata c.v.Xiangshui" was used as the scion to carry out dwarf ylang-ylang grafting varieties.

[0048] Rootstock preparation: choose rootstock as 2-year-old bagged seedlings (approximately 20 centimeters in seedling bag diameter, about 20 centimeters in height, used to limit the growth of ylang ylang-ylang root system), plant height 1.8 meters, plant diameter at breast height about 2.6 centimeters, and healthy plants without disease and insect pests; Five days before grafting, the rootstock was cut 25 cm away from the soil surface for "primary cutting of the anvil", with an incision angle of about 45 degrees.

[0049] Bud sheet scion preparation: select 2-year-old, strong, and non-mechanically damaged straight branches from the ylang-ylang tree to be grafted to make the bud sheet scion, cut off the leaves on the bud sheet scion branch, and keep...

Embodiment 3

[0056] Embodiment 3: the plant height observation of dwarf ylang-ylang after grafting of the present invention

[0057] Carry out grafting according to embodiment 1 method in 2013, observe plant height for 6 consecutive years, the results are shown in Table 1.

[0058] Table 1

[0059]

[0060]

[0061] As can be seen from the data in Table 1, after grafting by the method of the present invention, the plant height increase rate of the grafted Ylang-Ylang plant decreases year by year, tends to be stable, and the whole does not exceed 120 centimeters; After 6 years of planting, the plant height has exceeded 10 meters. This shows that the solution of the present invention can truly and significantly realize the dwarfing of ylang-ylang.

Abstract

The invention relates to the technical field of plant grafting, and discloses a grafting method for ylang-ylang dwarfing and year-round flowering. The grafting method of the present invention uses Ylang-ylang densiflora as the rootstock and Ylang-ylang perfumiga as the scion, and grafts through grafting; wherein, the rootstock is cut once before grafting, and the rootstock is cut for the second time 5 to 7 days after grafting; Intermittent bud-touching treatment is carried out during the root stock healing period, and the root stock bud points are cleaned in time until the scion grows new buds. In the dwarfing grafting process of ylang ylang in the present invention, with preferred ylang ylang-dense as the rootstock, with the ylang-ylang perfume as the scion, change the commonly used budding mode to the grafting mode, and carry out appropriate secondary cutting of the stock and intermittent grafting at the same time. The rootstock touch-bud treatment has significantly improved the survival rate of ylang-ylang grafted seedlings, realized the purpose of dwarf production and year-round flowering of ylang-ylang, and improved the benefits of ylang-ylang industrial planting.

Description

technical field [0001] The invention relates to the technical field of plant grafting, in particular to a grafting method for ylang-ylang dwarfing and year-round flowering. Background technique [0002] Ylang-ylang (Cananga odorata (Lam.) Hook.f.&Thomson) has important economic value and development prospects. Ylang-Ylang is a perennial tropical woody spice plant of the genus Ylang-Ylang (Cananga) in the family Annonaceae. It is known as the "World Champion of Fragrant Flowers" and "Natural Perfume Tree". The Ylang-Ylang essential oil extracted from its petals is a precious natural High-grade spices and high-grade deodorants have health effects such as anti-depression, antibacterial, aphrodisiac, lowering blood pressure, and sedation. They are daily-use chemical raw materials for the manufacture of perfumes, soaps, and cosmetics. [0003] At present, the world's ylang-ylang is mainly planted in the Comoros Islands, Madagascar, Mayotte and other regions, with an annual outpu...
