Rejuvenation culture method for aged and endangered ancient tea trees

Abstract

The invention relates to the field of planting, in particular to a rejuvenation culture method for aged and endangered ancient tea trees. The rejuvenation culture method for the aged and endangered ancient tea trees comprises the following steps: the rejuvenated ancient tea trees are prepared and can bear tea seeds, tea seeds of related tea tree varieties are selected, the tea seeds are cultivated in a container, the to-be-rejuvenated ancient tea trees are classified into a bud mutation variety and a whole variant variety, classification treatment is conducted, firstly, the ancient tea trees belong to the bud mutation variety, only part of the tea tree branches are subjected to bud mutation, the bud mutation branches are marked, and then non-bud mutation branches are classified and marked; the ancient tea trees belong to the whole variant variety, and all branches are classified and marked according to vulnerable branches, moderately strong branches and strong branches; and therefore, the aged and endangered tea trees can improve the nutrition supply while the tree vigor capacity is gradually recovered, and the overall vitality of the trees can be increased on the premise that the tree vigor capacity is enhanced.

Description

technical field [0001] The invention relates to the field of planting, and mainly relates to a method for cultivating ancient tea tree rejuvenation. Background technique [0002] Tea tree germplasm resources are indispensable and important materials for tea tree breeding and theoretical research. The development of new products such as black tea and white tea requires new germplasm support. Therefore, germplasm resources are important for the transformation and upgrading of the tea industry, especially for the development of new products. The basics. At the same time, breeding research requires a large number of local characteristic germplasm resources. Many excellent tea tree varieties are derived from the bud changes of ancient tea trees, such as "Anji white tea", "Hui Mingming tea", "Jinyun yellow tea", "Zicuckoo", etc., but these tea tree varieties with specific bud changes generally grow in ecological environment. The environment is poor, the growth potential is weak,...

Problems solved by technology

Many excellent tea tree varieties are derived from the bud changes of ancient tea trees, such as "Anji white tea", "Hui Mingming tea", "Jinyun yellow tea", "Zicuckoo", etc., but these tea tree varieties with specific bud changes generally grow in ecological environment. The environment is poor, the growth potential is weak, and it is generally a single plant, which is in an endangered state, basically cannot be transplanted, and management is difficult

The traditional model generally adopts the method of removing weeds and shrubs around aging and endangered ancient tea trees, artificially applying certain chemical fertilizers, organic fertilizers, etc. In the short term, the ancient tea trees will grow slightly better than the previous period, but the long-term effect is not good, because aging , Endangered ancient tea trees are basically in an aging state due to their physiological and biological characteristics, and their aboveground and underground root systems are relatively weak. In clearing the garden, fertilization can easily damage the already fragile root system, but the effect is not obvious
