Remedial Measures After Freezing Injury Of Tea Garden

1. Prune in time. After the tea tree is frozen, part of the branches and leaves lose their vitality and must be pruned to make new branches grow, cultivate the skeleton and pick the surface. Treat the tea trees according to the degree of damage. In principle, the frozen part can be cut off. In order to make the latent buds germinate better at the incision, it is better to place the trimmed part 1~2cm on the fork of the branch. The pruning period is appropriate after the temperature has risen steadily in early spring. Premature pruning can easily be attacked by the "back spring cold" and be frozen again.

Our company is committed to tea management and production equipment, and can provide customers with high-quality tea pruning machines.

2. Shallow tillage and fertilization. After thawing, shallow ploughing and fertilization in early spring play a major role in increasing the ground temperature and cultivating soil fertility. In addition to topdressing quick-acting nitrogen fertilizer to promote the germination of tea buds and the growth of new shoots, some mineral phosphorus and potassium fertilizers can also be used to enhance the growth ability of branches and promote the production of summer tea. After the freezing injury occurs during the spring tea germination period, spraying foliar fertilizer when the tea bud fish leaves to one leaf unfolds can promote the restoration of tea tree vitality and the germination of young buds and the growth of new shoots. It can be sprayed with 0.5% urea.

3. Cultivate the canopy. After the plants are frost-damaged, the branches and leaves will scorch and fall off, and the leaf area will be significantly reduced. In the picking method, it is necessary to strengthen the leaves and shoots, and the method of multiple picking in multiple batches.

Applying reasonable pruning methods, fertilizing methods, and cultivating tree crowns can promptly recover the loss after freezing damage. Make the tea tree quickly regain its vitality.
