Bird king tea cutting reproduction method suitable for karst region

Abstract

The invention relates to a bird king tea cutting reproduction method suitable for the karst region. The reproduction method includes the following steps: (1) selecting a tea tree variety; (2) preparing a cutting medium: evenly mixing, by mass, 3-4 parts of mixed soil samples, 4-6 parts of edible mushroom slag, 2-3 parts of silkworm excrement and 3-4 parts of rice bran shells, adding 2-3 parts of Lonicera hypoglauca dregs, controlling the pH of soil in 4.0-5.5, and paving the cutting medium on a wooden box for use, wherein the mixed soil samples includes 10 parts of humic acid soil in the karst mountain and 1-3 parts of Guizhou plateau swamp soil; (3) preparing cutting seedlings; (4) performing cuttage; and (5) cuttage management. The method can improve the growth speed of cutting seedlings of the bird king tea trees, is stable in survival rate, is low in cost, can play a role in retaining water and soil in the karst region, can achieve large-scale planting of the bird king tea trees, and provides a road to fortune for farmers in a Guizhou karst mountainous area.

Description

technical field [0001] The invention relates to a cutting propagation method of Niaowang tea suitable for karst areas, and belongs to the technical field of forward cutting propagation of tea plants. Background technique [0002] Niaowang tea has become a high-quality tribute tea as early as the prosperous Tang Dynasty. "Guiyang Fuzhi" (Shihuo Volume) in the Wanli period of the Ming Dynasty stated that "all provinces in Guizhou produce tea, and Guiding Yunwu is the most famous". One of the eight famous teas in China. Niaowang tea was used as a tribute as early as the Yuan Dynasty, and it is a rare and precious variety of tea. Niaowang tea is mainly produced in Guiding County, Guizhou Province, at the foot of Yunwu Mountain at an altitude of more than 1,560 meters. As a high-quality tea, Niaowang tea is determined by the local Niaowang species with high grade, good quality and good physical and chemical indicators. More than 2,000 years ago, the artificial cultivation of te...

Problems solved by technology

[0005] In recent years, people's demand for tea is increasing day by day. In order to expand the area of ​​cultivated varieties and improve the yield and quality, local farmers do not pay attention to science and technology and blindly expand the area of ​​tea plantation. The frequent occurrence of hazards such as water and soil erosion has seriously damaged the natural ecological environment

[0006] At present, the cutting propagation of Niaowang tea adopts the traditional cutting propagation method, which is covered with a film for heat preservation. This propagation method usually uses untreated mother tree resources for cutting, which is easy to rot, and the survival rate of reproduction is relatively low, and the cost of cutting propagation is high.

Another cutting propagation method is to use tea tree branches to take short-ear cuttings for propagation, that is, place the tea tree explants on an outdoor ordinary medium for propagation. In order to promote the cutting seedlings to take root and survive as soon as possible, the raw root powder is soaked in water for 3 hours. Cutting after cutting, although this cutting propagation method can make the cutting seedlings take root and survive as soon as possible, but the cutting seedlings cannot fully absorb the nutrients in the soil, the cutting growth speed is slow, and the survival rate is unstable.
