Embodiment 1

[0035] (1) Seedbed construction: The mass ratio of seedbed soil is: the bottom soil layer is composed of 85% acidic red loam and 15% fine river sand, with a height of 20cm-25cm; The soil is used as the core soil layer, and the red soil core soil with a height of 6cm to 8cm is used as the topsoil layer, which is scraped and slightly compacted to form a seedbed with a width of 110cm and an east-west direction. The interval between the seedbeds is 33cm. Open a 53cm wide and 45cm deep ditch around the seedbed.

[0036] (2) Seedbed disinfection and sunshade: the mass concentration is 45% carbendazim solution to spray the seedbed, cover the grass and suffocate the soil for 18 days, build a high shade shed with a shading degree of 65% and a height of 1.65m on the seedbed, and shade materials Using sunshade net, the shading rate is 75%.

[0037] (3) Collection of cuttings: The cuttings are collected in late December, and the annual thick branches of the young and middle-aged large-le...

Abstract

The invention relates to a cutting propagation method of yellow tea. The method comprises the following steps: (1) seedbed construction; (2) seedbed disinfection and shading; (3) collection of cuttings: the cuttings are selected from the annual thick branches that have been pruned deeply or regenerated by platform mowing on young and middle-aged etiolated tea trees (4) Cutting treatment: select the middle and lower part of the gained cuttings of step (3) near lignified or lignified parts, and cut the cuttings, and the cuttings after cutting have a full axillary bud and a strong leaf; ( 5) cuttings; (6) water management. The cutting propagation method of the yellow tea of ​​the present invention greatly improves the survival rate and the rooting rate of the cutting propagation of the yellow tea.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a cutting propagation method of yellow tea. Background technique [0002] The development and utilization of high-quality and specific resources is an important part of promoting the development of the tea industry. As a kind of characteristic germplasm resources with different color from normal shoots, etiolated tea tree germplasm resources not only have the ecological value of ordinary tea trees, but also have much higher ornamental and economic value than ordinary tea trees. Compared with normal color tea leaves, the processed products have unique advantages in quality and health care functions, and are favored by the market. [0003] In order to obtain a large amount of tea tree seedlings, tea trees are mainly propagated by methods such as cuttings and grafting. The tea tree varieties with normal color have strong growth potential, and a large number of seedlings can be ob...
