Holly propagation method

Abstract

The invention discloses a holly propagation method which comprises the following steps: adding absolute ethyl alcohol containing alpha-terpilenol into holly residual leaves, and carrying out ultraphonic digestion to obtain holly extractive; taking garden soil, peat moss, zeatin, coir dust, vermiculite powder and river sand, adding water, and carrying out fermentation to obtain nutrient soil; scissoring half-lignified twigs, and soaking the twigs in a rooting powder solution containing rooting powder ABT6, chitosamine and mannitol; inserting cuttings in a slotting machine filled with the nutrient soil and the holly extractive, covering a film and cultivating; after the cuttings take root, carrying out hardening-seedling and transplanting, and carrying out water and fertilizer management after seedling recovering. The holly propagation method is simple to operate, high in repeatability, low in cost and high in production efficiency; the raw materials are easy to obtain; the method can ensure holly cuttings to be high in rooting percentage, high in survival rate and developed in root growth; and the obtained seedlings are high in quality, so that the cultivation period is effectivelyshortened, and the holly propagation coefficient is increased.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a propagation method of holly. technical background [0002] Holly, an evergreen tree, is a kind of flowering plant and the only genus under the Ilex family. Its bark is gray or light gray, with longitudinal grooves, and the branchlets are light green and glabrous. The leaves are thin leathery, long and narrow oval or lanceolate, apex acuminate, base cuneate, edge with shallow circular serrations, reddish brown and shiny after drying.

Widely distributed in Asia, Europe, North Africa, North America and South America. In China, it is mainly distributed in the provinces and regions south of the Yangtze River Basin. [0003] Holly has high medicinal value. The leaves, roots, bark, and see...

Problems solved by technology

[0005] Holly is mainly propagated by seeds and cuttings. Although seed propagation has the advantages of easy collection and high germination rate, if it is directly sown and planted with holly seeds, it usually needs to be stored for germination and planting every other year, and the interval is longer. In the storage process, the seeds are also prone to mildew and insects, which will affect the germination rate and germination quality.
