Grafting propagation method of yellow camellia

Abstract

The invention relates to a propagation method of yellow camellia, in particular to a grafting propagation method of yellow camellia. The grafting propagation method comprises the steps of cutting a rootstock; whittling a scion bud, wherein the scion bud is 1.8-2.2 cm long, one bud and one leaf are kept, half of each leaf is sheared, the part 0.4-0.6 cm from the upper end of a flat axillary bud is cut, the lower end of the flat axillary bud is kept by 1.2-1.8 cm, when the scion bud is whittled, a whittling opening of 12-17 degrees is aslant and downwards cut at the two sides of the part 0.3-0.5 cm from the lower part of the bud to form a pointed wedge-shaped scion bud with the cut length of 1-1.5 cm and of 25-35 degrees, and the scion bud after whittling is directly inserted into a rootstock opening; conducting grafting, wherein the whittled wedge-shaped scion bud are straightly inserted into the rootstock opening, a cambium layer of the scion bud and the cambium layer of the rootstock need to be aligned during inserting the scion bud, then the scion bud is bound up with a grafting special aluminum sheet, and a grafting opening is sleeved with a thin film bag; conducting filed planting, wherein after grafting, the scion bud is covered with a damp towel to preserve moisture, and is planted into a prepared nursery field in 25-30 min. The provided grafting propagation method of yellow camellia is high in survival rate and sprouting rate, early in blossom, low in cost, and suitable for large-scale production.

Description

technical field [0001] The invention relates to a breeding method of camellia japonica, in particular to a method of grafting and breeding of camellia japonica. Background technique [0002] Camellia Camellia is the only species with golden petals in the Camellia family. It is a rare ornamental plant and germplasm resource. It is a first-class protected plant in my country. It has important medicinal value and scientific research value. It is known as the "Queen of the Tea Clan". The roots, leaves and flowers of Camellia chrysalis can be used as medicinal materials, and the flowers and tender leaves can also be made into tea leaves. Camellia camellia was first discovered in Guangxi in the 1960s. In recent years, domestic and foreign experts and scholars have studied the geographical distribution, population ecology, biological characteristics, genetic diversity, morphological characteristics of pollen, chemical components, introduction and cultivation of Camellia camellia pl...

AI Technical Summary

Problems solved by technology

Research on Camellia Camellia reproduction and seedling cultivation includes seedling breeding for sexual reproduction, cuttings, grafting, high-altitude layering for asexual reproduction, etc., but each method has advantages and disadvantages. The cost of propagation is relatively high, cutting and layering all need to consume a large amount of propagation materials, the cost is high, and the propagation speed of high-altitude layering is slow and the reproduction coefficient is low, which is not conducive to the large-scale production of asexual propagation of Camellia japonica
