The kiwi tree is a temperature-sensitive fruit tree and is therefore susceptible to low temperatures during the winter months. If the kiwi tree is frost damaged, it needs to be treated in time to avoid losses. The following is an introduction to the treatment of kiwi trees after they are frozen.
1. Prune in time.
If a kiwi tree is frost damaged, the first thing you need to do is check whether the tree is damaged. If the tree is not damaged, light pruning can be done to remove severely frost-affected branches and leaves. When pruning, cut lightly and do not hurt the tree.
2. Strengthen fertilizer and water management.
After pruning, fertilizer and water management should be strengthened to promote the recovery of kiwifruit trees. Some fast-acting fertilizers, such as urea, can be used for extra-root topdressing to promote the growth of the tree. At the same time, it is necessary to keep the soil moist to avoid drought having a greater impact on the tree.
3. Prevention and control of pests and diseases.
After the kiwi tree is frozen, it is susceptible to pests and diseases. Therefore, it is necessary to check the tree body in time for the occurrence of pests and diseases, and take corresponding control measures. Some biological pesticides can be used for control, such as BT emulsion.
Fourth, strengthen thermal insulation measures.
Before the onset of winter, it is necessary to strengthen the insulation measures to avoid the influence of low temperatures on the kiwifruit trees. Some insulation materials, such as straw mats, films, etc., can be used to cover the tree to maintain a suitable temperature.
5. Strengthen management.
After the kiwifruit tree recovers its growth, it is necessary to strengthen management and promote the growth and development of the tree. Management work such as cultivating and weeding, pruning and shaping, fertilizing and watering can be carried out to maintain the health and growth of the tree.
In conclusion, kiwi trees need to be treated in time after being frozen to avoid losses. The recovery and growth of kiwifruit trees can be promoted through timely pruning, enhanced fertilizer and water management, pest and disease control, enhanced thermal insulation measures, and enhanced management.
