The present application belongs to the technical field of
tea tree cultivation, and discloses a cultivation method for promoting multi-root resistance of asexual tea seedlings, comprising:
seedbed preparation; selection and treatment of
bud sticks;
cutting and water and
fertilizer management; composition application: 15-20 days after
cutting of the tea seedlings,
Trichoderma harzianum is applied by root
irrigation, and the
fungus is applied periodically twice; 45-50 days after
cutting of the tea seedlings, water-soluble
fertilizer containing
Ascophyllum nodosum is applied through a
drip irrigation system, and the
fertilizer is applied periodically 2-3 times;
seedling hardening. The
Trichoderma harzianum is applied at the initial stage of root formation of the tea seedlings to promote root
colonization and root
primordium differentiation, and the water-soluble fertilizer containing
Ascophyllum nodosum is applied after the root formation to provide
nutrition, and the two are combined in time to significantly promote multi-rooting of the tea seedlings, enhance the resistance, and improve the
survival rate, and the operation is simple, and the method is suitable for large-scale breeding of asexual tea seedlings, and is especially suitable for
arid and semi-
arid areas in the north.
