Propagation method of camellia amplexicaulis cohen stuart by using shoot cutting

Abstract

The invention discloses a propagation method of camellia amplexicaulis cohen stuart by using shoot cutting. The propagation method comprises the steps of: firstly, transplanting mother seedlings which are cultured through seedling culturing and are taken as cutting mother seedlings into a garden using composted organic fertilizers and calcium magnesium phosphate fertilizers as base fertilizers, and culturing, wherein the plant spacing between the two adjacent rows is 25cm*30cm; performing cutting back and sprouting promoting at a position where a mother plant base parts is 10-15cm away from the ground, collecting cutting woods with branch lengths of 5-8cm, and cutting in a cutting bed provided with a cutting substrate; and controlling illumination, relative humidity and substrate water content in the cutting bed to obtain a cutting seedling of the camellia amplexicaulis cohen stuart. According to the propagation method, the garden for culturing the mother seedlings, an exposed plot isselected for ridging and close planting, the mother seedlings are developed in root systems, are high in growth speed and are also high in growth speed of branches sprouting, a rejuvenating effect oflow-level trunk cutting is good, cutting woods are easy to root and are shorter than branches in the common shoot cutting, and thus a collecting interval of the cutting woods can be shortened, the propagation efficiency is improved, and 5-6 times of cutting propagation can be carried out one year, so that a large quantity of seedlings are obtained; and the propagation method has the advantages ofbeing low in production cost, relatively small in material consumption, simples in operation, large in supply quality of the cutting woods, and relatively good in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a method for propagating the tender branch cuttings of Vietnamese clam tea. Background technique [0002] Camellia amplexicaulis (Pitard) Cohen Stuart belongs to the Theaceae (Theaceae) Camellia (Section Archecamellia Sealy), the flowers are purple, the buds are spherical, the leaves are large, and the leaf bases are clasped. Named "hugging stem tea", it has shade-loving characteristics. Under suitable cultivation conditions, it can bloom all year round, and the plant type is compact and the leaf shape is peculiar. It is an excellent garden greening and indoor foliage and flowering plant cultivation. It is also one of the parental materials for cultivating new varieties of Camellia that bloom in four seasons. Due to these rare and special ecological characteristics of Vietnamese stalk tea, it has aroused great interest among camellia lovers. In recent years, t...

[0003] At present, Vietnamese stalk teas are grown with seeds (seeds), and Vietnamese stalk teas are only distributed in natural forests in Vietnam. The seedlings used in the market are all from Vietnam, and the seeds of Vietnamese stalk teas germinate for a long time. , It takes almost a year to accelerate germination with sand storage, the cultivation period is long, and the co
