Method for growing seedlings of six-petal stone pencil wood container cuttings

Abstract

The invention discloses a method for cutting and raising seedlings of tutcheria hexalocularia employing a container. An offspring plant container seedling which is kept consistent with an excellent single strain in inheritable characters is obtained in manners of selecting an excellent single strain of the tutcheria hexalocularia as a stock plant by an inventor; selecting a nursery land, and preparing soil; preparing and sterilizing matrix; collecting, cutting and processing cuttings; moisturizing, shading, managing after rooting, and the like. Blooming is earlier than sowing seedling, and the cutting survival rate and the transplanting survival rate are high. The method disclosed by the invention is simple to operate, low in production cost and applicable to vegetative propagation of excellent single strain of the tutcheria hexalocularia; the difficulties of propagating and transplanting of the excellent single strain of the tutcheria hexalocularia can be effectively solved; the method can be applied to massive cultivation of seedlings of rare plants and excellent ornamental tree tutcheria hexalocularia; the difficulty of seedling of the key protected wild plant, namely the tutcheria hexalocularia in Guangxi can be broken through; protection of the rare plant tutcheria hexalocularia resource, and application and promotion thereof in landscaping are facilitated.

Description

technical field [0001] The invention belongs to the technical field of plant container cutting propagation, and in particular relates to a method for raising seedlings by cutting in a six-petal stone pencil wood container. Background technique [0002] Tutcheria hexalocularia is an evergreen tree of the family Theaceae, 12 meters high, with thick shoots and glabrous leaves; leathery, oval, alternate, serrated edges; bisexual flowers, white or light yellow, Born solitary in the axils of the top leaves, flowering from May to June; capsule oblate, 5-6 cm wide, 3-3.7 cm high, 6-chambered, 6-valve split, covered with brown hairs. Six-petal stone pen wood is mainly distributed in Guangxi, Guangdong, Yunnan and other places. The six-petal stone pen tree has a straight trunk and a beautiful tree shape; the leaves are bright green; it blooms in summer, with a large amount of flowers, and the color is white or light yellow; it can be used for gardens, parks or street greening; Ideal...

Problems solved by technology

However, there is no report about the container cutting seedling cultivation of the six-petal stone pen tree so far.

In recent years, the inventors have adopted seedbed cutting seedling breeding technology to propagate Hexapetia spp., and the survival rate of cuttings is 61%, but the transplanting survival rate of annual Hexapodia is only 20-30% when it is removed from the seedbed and planted in the nursery. It shows that the technology of cutting seedlings in seedbeds is of low application value in the propagation of S.
