Breeding method of wild large-leaf tea tree

Abstract

The invention discloses a breeding method of a wild Daye tea tree. The method comprises the following steps of: selecting a seedling culture field as a seedbed; vertically placing a cylindrical mesh-bag seedling culture container industrially produced on the seedbed; selecting a semi-hardwood branch of the wild Daye tea growing in the current year; shearing the branch into cutting branches each of which contains a tea leaf; performing asexual cutting breeding from July to October every year; rooting the lower part of the cutting branch, and then planting the cutting branch into the seedling culture container; tightly pressing the lower part of the cutting branch by hands, and exposing one tea leaf out of the ground; arranging a sunshade net above the seedbed; keeping the seedbed wet; and when the tea leaf seedling grows to 16-20cm high, transplanting the tea tree seedling to a garden together with the seedling culture container. Through the invention, the mesh-bag container can be industrially produced, thereby being very simple and convenient; since the formula matrix preserves moisture and fertility and is permeable and breathable, the seedling rate can reach 90%; when in transplanting, the rejuvenation period is short, and the survival rate is high to 85%; and the mesh-bag container seedling is planted into soil so as to prevent pollution.

Description

technical field [0001] The invention relates to plant breeding, that is, a method for breeding wild big-leaf tea trees. Background technique [0002] In 1969, Lu Wanjun and others found a nearly 100-year-old wild big-leaf tea tree with excellent quality in the deep mountains of Taipingpu Township, Taoyuan County, Hunan Province. In 1992, it passed the approval of the Hunan Provincial Crop Variety Approval Committee and named it "Taoyuan Daye". [0003] Taoyuan big-leaf tea has now become a local high-quality tea tree variety unique to Taoyuan County, Hunan Province. All kinds of tea made from Taoyuan big-leaf tea are emerald green, fresh and strong, and have a long-lasting fragrance. In October 2005, Taoyuan big-leaf tea was protected by the country as a product of origin, and the "Wild Tea King" processed from big-leaf tea has been certified by the National Geographical Indication. In recent years, under the great attention of the Taoyuan County Party Committee and the co...

Problems solved by technology

[0006] Although this conventional asexual cutting propagation method has achieved some results, its disadvantage is that the survival rate of seedlings is low, only 60%, and the survival rate of transplanting is not high, only 70%.
