Grafting method for dwarfing and year-round blooming of Cananga odorata

Abstract

The invention relates to the technical field of plant grafting and discloses a grafting method for the dwarfing and year-round blooming of Cananga odorata. The method comprises the steps of carrying out scion grafting by taking Cananga odorata c.v.Mihua as a rootstock and Cananga odorata c.v.Xiangshui as a scion, wherein the primary rootstock cutting is carried out before the grafting, and the secondary rootstock cutting is carried out after 5-7 days of the scion grafting; and carrying out intermittent bud touching in the rootstock-scion union period, and timely cleaning bud sites of the rootstock until new buds grow from the scion. Cananga odorata c.v.Mihua and Cananga odorata c.v.Xiangshui are respectively taken as the rootstock and the scion in the dwarfing grafting process of Cananga odorata, a common exposed bud grafting manner is changed into the scion grafting manner, and meanwhile, the two proper rootstock cutting processes and the intermittent bud touching processing are carried out, so that the survival rate of grafted Cananga odorata seedlings is remarkably increased, the dwarfing production and year-round blooming purposes of Cananga odorata are achieved, and the industrial planting efficiency of Cananga odorata is improved.

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...

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.
