What if the kiwifruit tree is frozen?

Kiwifruit has strong adaptability to the environment and has been planted in most parts of our country, but due to the influence of climatic conditions, we need to prepare kiwifruit to survive the winter before entering winter in some areas. But sometimes there will be freezing, so after the kiwifruit tree is frozen, how can we remedy it? Let's learn about it together.

1. Strengthen management and supplement nutrition

After kiwifruit is frozen, its vitality is very fragile, in order to restore the growth of kiwifruit, then we need to strengthen the soil and fertilizer management in the garden to supplement the nutrients needed for kiwifruit growth, so as to restore the tree potential as soon as possible. First of all, we should increase the application of fertilizer combined with watering, and spray an appropriate amount of photosynthetic nutrient film fertilizer, which can strengthen the photosynthesis of trees, improve the utilization efficiency of fertilizer, and promote the growth of new branches. Or it can be sprayed with Canon and Yizhikang, as well as probiotics, which are also used to promote the growth of branches and leaves and enhance the vitality.

2. Bridging, grafting or seedling replenishment

Bridging is usually in the kiwifruit tree when the degree of freezing damage is small, or the initial fruit tree, then we can bridge the freeze-damaged parts of the trunk before sprouting. However, if the kiwifruit tree is seriously damaged by freezing, then we have two ways to deal with it. The first is to plant new varieties and strengthen management as soon as possible, and the second is to replant and replenish seedlings to achieve premature and high yield as far as possible.

3. Pruning frostbitten branches

After the kiwifruit trees are frostdamaged, we need to prune the frostbitten parts after the new branches sprout, and trim the rest of the branches and leaves as much as possible, leaving a branch that can grow into a crown in the same year. In addition, after pruning the frostbitten parts and other branches, in order to prevent the branches from being infected by germs, we had better apply a layer of anticorrosive film in time, which can effectively protect the branches and promote wound healing.

4. do a good job in the control of diseases and insect pests

After the kiwifruit tree is frozen, its own immunity and resistance are correspondingly reduced, if no protective measures are taken, it is easy to be damaged by diseases and insect pests. First of all, we need to trim off the frost-damaged branches, then seal the trimmed area with 50 times oil emulsion, and when the block is sprouting, we can spray the right amount of Baumedu stone sulfur mixture. this can effectively prevent canker and other pests and diseases.
