Seedling growing method for tea trees

Abstract

The invention discloses a seedling growing method for tea trees.The method comprises the steps of shearing spikes, preparing a water culture container, performing water culture on cut spikes, preparing a red soil solution, transplanting to a nutrition pot, hardening seedlings and the like.First, a field planting tray is used for dividing the water culture container into an upper cavity and a lower cavity, and cut spike branches are made to penetrate through the field planting tray, fixed and then subjected to water culture.In the water culture process, temperature and humidity are controlled at different segments, the temperature of the upper cavity is kept at 10-12 DEG C, the humidity is controlled at 70-80%, and the water temperature of the lower cavity is kept at 30-32 DEG C; low temperature and high humidity are utilized for lowering metabolism of buds and leaves of the cut spikes, so that moisture and nutritional substances in cut branches are better locked, and meanwhile high-temperature water culture is utilized for promoting rooting at the bases of the cut branches.The cut spikes subjected to water culture are transplanted to the nutrition pot for hardening seedlings 20 days after releasing air and growing roots.Through the method, the requirement on the cut branches is lowered, a part of non-semi-lignified scions in the branches are utilized, and the survival rate of tea seedlings is increased.Meanwhile, the method has the advantages that operation is easy, the rooting speed is high, the seedling growing cost is lowered, and maintenance is more convenient.

Description

technical field [0001] The invention relates to the field of cutting propagation of tea trees, in particular to a method for raising seedlings of tea trees, and has guiding significance for most woody plants. Background technique [0002] Tea tree is a perennial economic crop, and its propagation method is divided into sexual propagation and asexual propagation. Among them, sexual reproduction is to broadcast tea tree seeds for propagation, which has the advantages of strong adaptability to the environment and low cost of seedlings, but its disadvantages are mixed economic traits among plants, large growth differences, inconsistent growth periods, and inconvenient management. Some tea tree varieties with low seed setting rate are difficult to propagate by seeds. Because asexual reproduction can maintain the characteristic characteristics of fine varieties, the traits of offspring are highly consistent, and it is beneficial to the management of tea gardens. It has attracted ...

Problems solved by technology

[0005] In view of this, the purpose of the present invention is to provide a method for raising seedlings of tea trees, which is not limited by seasons and can be cut in all seasons, which solves the problem that traditional tea tree seedling raising methods are difficult to apply to non-semi-lignified branches and hairy roots. The problem of slow speed and low survival rate
