Method for conducting single node cutting seedling cultivation by utilizing branches after spring tea-picking in three-dimensional tea garden

Abstract

The invention discloses a method for conducting single node cutting seedling cultivation by utilizing branches after spring tea-picking in a three-dimensional tea garden. The method comprises the steps of carrying out comprehensive preservation of fish leaves or one-leave picking on spring treetops sprouted on overwintered braches in the three-dimensional tea garden; from after spring tea-picking to before second round tea sprouting, raising pruning openings by 3-5cm to be subjected to ear and branch cutting after the spring of the last year; conducting ear removal and cutting on the cut ears and branches according to a regular single node cutting seedling technology; from early June to early July, in the sprouting and growth process of new treetops of the cut ears, pruning sprouted young buds and promoting the growth of a main sprout in time. According to the method for conducting the single node cutting seedling cultivation by utilizing the branches after the spring tea-picking in the three-dimensional tea garden, efficient utilization of tea tree biological resources is achieved, and by the reuse of the pruned and waste branches and treetops after spring tea in the three-dimensional tea garden, the utilization rate of the tea tree biological resources are increased, and the method is particularly suitable for reproduction and popularization of new varieties of tea trees with scare resources; an annual seedling cultivation period is prolonged, and the history that cutting seedling cultivation cannot be carried out for long time due to the fact that no cutting is conducted between spring the summer is changed; three-dimensional tea garden management achieves double benefits which takes tea leaves and ear harvest into account.

Description

technical field [0001] The invention relates to a method for raising seedlings by cuttings, in particular to a method for raising seedlings by short-ear cuttings by utilizing post-harvested shoots of spring tea in a three-dimensional tea garden. Background technique [0002] Tea tree short panicle cutting seedling cultivation is currently the best way to advance the improvement of tea tree clones, which can achieve rapid multiplication of tea seedlings while maintaining the excellent characteristics of the mother tree. [0003] The "short spike" technical feature of short spike cutting seedlings is to use "one bud, one leaf, one inch long" spike branches, which require appropriate thickness, length, maturity and integrity. The general requirements are: the thickness of the short ear is 2.5mm-5mm, with 3mm-3.5mm being the best; the length is 2.5cm-4cm; Each cutting contains a full axillary bud and a complete leaf. The upper and lower cuts are required to be smooth, and the b...

Problems solved by technology

[0011] 2. Spring cuttings have caused a major reduction in the production of spring tea in the current year. Spring teas cannot be harvested because plum cuttings need spring shoots as fringes. Late autumn cuttings and winter cuttings have most of the impact on spring tea production in the second year.

Since spring tea occupies most or all of the annual income of tea gardens, it is not possible to balance ear picking and tea picking.
