Rapid method for developing different camellia varieties in the same tree

Abstract

The invention discloses a method for rapid developing multi-variety camellia on a tree, which belongs to a method for grafting trees in horticulture. The method comprises the processes: (1) technique of selecting variety of rootstock and scion; (2) technique of transplanting rootstock; (3) technique of grafting the scion; (4) managing technique after transplanting and grafting. The method for rapid developing multi-variety camellia on a tree of the invention has the advantages that grafting can be carries out at all seasons; varieties of the rootstock and the scion are not limited with a high survival rate and quick growth; flower blossoms out in current year; the survival multi-variety camellia has strong adaptive capacity and can grow and blossom in a temperature of -6 to 35 DEG C. By adopting the invention, gene of the camellia can be promoted to change, which makes the camellia grow developed fibrous root but not earth root and have little sideway root; the camellia only blossoms red and white flowers can be changed in a short period into an unique tree which can blossom tens of varieties of flowers, which achieves an effect of beautifying environment and is used for an occasion that the camellia is regarded as ornamental trees. The invention is a gardening technique with a strong artistry.

Description

[0001] Field [0002] The invention belongs to a method for grafting and cultivating trees in horticulture, in particular to a method for grafting multiple varieties of camellias on tea trees. technical background [0003] Camellia (Camellia japonica) is a tree of the family Theaceae, blooming in winter and spring, with large flowers, often bright red. There are many varieties in horticulture, both single petals and double petals, and the flower colors are red and white. Today both at home and abroad mainly produce camellia with the method of planting by cuttings, and there are few of grafting and propagation. For a small number of high-grade camellia varieties that do not survive cuttings, such as Yunnan Dali tea, Zhangjia tea, Zipao, Jiulong lion head, Tongzi noodles, etc., some people also use grafting to propagate, but the survival rate is not ideal; It also needs long-term cultivation. Normally, it takes 7 to 8 years for a camellia to be successfully cultivated from roo...

Problems solved by technology

For a small number of high-grade camellia varieties that do not survive cuttings, such as Yunnan Dali tea, Zhangjia tea, Zipao, Jiulong lion head, Tongzi noodles, etc., some people also use grafting to propagate, but the survival rate is not ideal; It also needs long-term cultivation. Normally, it takes 7 to 8 years for a camellia to be successfully cultivated from rootstock and grafted, and it will take 3 years at the fastest.

The traditional grafting method of camellia is grafting, and the patent application CN200510023485.7 "Camellia big tree fast-growing technology-card grafting" is a typical method of this method. Although this method can graft living camellias, it needs to use small potted trees As a scion, it can only be carried out in small quantities, and generally only a single variety can be grafted
