Method for propagating tea plants

Abstract

The invention relates to a method of propagation, in particular to a method for propagating tea plants (also known as camellia sinensis). The method comprises the following steps: (1) the first stage, inducing primary roots: cutting the collected branches of the tea plants into 3cm to 5cm long sprigs and carrying out the root induction for 10 to 30 minutes by growth hormones, then, cutting the processed sprigs in a soilless culture substrate and further arranging the substrate in a rooting environment under artificial regulation; and (2) the second stage, inducing secondary roots: planting the whole tea plant seed which is subjected to the first stage of induction of the primary roots in a nutrition bag filled with nutrition soil, and watering the tea plant seed for 15 to 25 days by depending on whether the surface of the nutrition soil turns white. By carrying out the root induction of the two stages, the invention has the advantages of simple operation, high propagation coefficient, low investment cost and easy popularization; and the invention constitutes the best way to propagate the rare difficult-to-root tea plant variety.

Description

technical field [0001] The invention relates to a propagation method, in particular to a tea tree propagation method. Background technique [0002] Traditional methods of tea tree propagation mainly use technologies such as cuttings in small arched sheds, grafting, and tissue culture. Cutting propagation and grafting propagation in small sheds and fields are limited by seasons, generally only in winter and spring, and have disadvantages such as low rooting rate, low reproductive success rate, and low reproductive coefficient for rare and difficult-to-root varieties. Although tissue culture has no disadvantages such as seasonal restrictions and low reproduction coefficient, it has problems such as difficult rooting induction, long cycle, seedling hardening, high investment cost, large investment in equipment and instruments, and difficult operation by non-professional technicians, which limits its promotion. Contents of the invention [0003] In order to overcome the above...
