Protective cultivation method of young tea trees of Ruixue No.1 tea

Abstract

Disclosed is a protective cultivation method of young tea trees of Ruixue No.1 tea. The protective cultivation method includes steps: before spring tea in a new tea garden planted in autumn and winter germinates and unfolds in the next year, covering a small arch shed with a thin film and a shade net; during planting, for a new tea garden planted before spring, directly covering a small arch shed with a shade net; uncovering the thin film at the later stage of germinating and unfolding of the spring tea, and uncovering the shade net on early June; applying quick-acting nitrogen fertilizer for one time from middle April to early May, and then performing conventional tea garden management of the current year; if the trees develop not well enough in the current year, applying the quick-acting nitrogen fertilizer for one time before spring tea germinates and unfolds of the next year; in spring of the next year, when the trees develop well in the previous year, fully plucking over fish leaves of spring tea, removing whitened shoots, and performing shaping and trimming after spring; when the trees develops not well enough in the previous year, performing shaping and trimming before spring, covering the small arch shed with the thin film and the shade net to promote spring shoots to return green, uncovering the thin film and the shade net like the previous year, and performing conventional tea garden management. By the protective cultivation method, whitening of shoots is controlled, and the shoots are prevented from physiological damage like sunlight burning.

Description

technical field [0001] The invention relates to a method for protecting and cultivating Ruixue No. 1 young tea tree. Background technique [0002] Ruixue No. 1 is a new generation of low temperature sensitive white albino tea (also known as white leaf tea) variety bred by Siming Xueya as the female parent. The albino characteristics of this variety are: [0003] 1. Shoot albinism is induced by low temperature, but the albinism expression is not strongly dependent on low temperature, and the upper limit of the albino temperature threshold is high (about 25-26°C, while the female parent is 23-25°C, Baiye 1 22 -23°C), so it is suitable for a wide range of planting, and can be cultivated in South China and Southwest tea areas in my country. [0004] 2. The albinism only occurs in the new shoots that germinate in spring, and the albinism phenomenon can be maintained until the spring shoots mature before turning green; the summer and autumn shoots are the same as the conventional ...

Problems solved by technology

[0006] 4. Highly albino new shoots have low resistance to sunlight

For the albino new shoots of one-year-old and two-year-old tea trees that have not been put into production, when they encounter sunny days at 25-27°C for 2-3 days before turning green, they will experience sunburn and other phenomena, and because the young tea trees are small , mature leaves are few, and the tree is weak. When the new shoot withers and dies, the impact on the subsequent development of the young tree is far greater than the impact of the new shoot being daylighted, and severe stunting or even the death of the whole plant will occur.
