Kiwifruit trees must pay attention to the following four key points in preventing frost damage in winter

In winter, as the temperature continues to decline, kiwifruit growers will be busy for a while, pruning branches and leaves of kiwifruit, watering and irrigating kiwifruit trees to prevent frost damage should be solved. One of the most important is the anti-freezing work. Doing a good job of anti-freezing in kiwifruit orchards in winter will effectively reduce frost damage.

1. Key points of preventing frost damage of kiwifruit trees in winter

1. Clear the snow

Recently, as the temperature continues to drop, it is about to usher in the snow weather. After the snow, it is necessary to clean up the snow on the branches and under the shelves of rhesus monkeys and peaches in time, which will cause damage to the branches and buds and lead to sprouting in the second year. After clearing the snow on the shelf surface and the lower part of the rhizome, it should also be matched with the way of cultivating soil to prevent freezing.

2. Keep the trees warm

Dry corn stalks can be used to keep trees warm. If you do not prepare corn straw in advance, you can also use cotton clothes that are not worn at home, or other materials with good air permeability and warm properties, and the height of the package should be more than one meter. In case of continuous low temperature and snowfall, Kuaikuling + Wofengsu + brown sugar + organosilicon can be used to brush the trunk.

3. Tree brushing treatment

The tree was brushed with biological germicidal smear + phytonutrient + brown sugar + organosilicon, and combined with biological germicidal smear + phytonutrient + brown sugar + organosilicon + potassium sulfate + calcium nitrate spray. Rebrush those trees that are prone to frost damage 3 times. The first time plays the role of wound repair, the second time plays the role of killing potential hidden bacteria, and the third time plays the role of adding nutrients to enhance the tree's ability to keep out the cold. Sugars not only improve the nutrition of trees, but also increase the content of soluble sugar in tree cells, so as to reduce the freezing point of trees. So that the tree has a stronger ability to resist low temperature.

4. Pruning branches

Choose less cold weather to prune the branches of kiwifruit trees. About half of the branches need to be pruned in the growing season, not in winter. Winter belongs to the dormant period of kiwifruit trees, pruning branches in winter is not as operable as pruning in growing season, because rhesus monkeys stop growing and pruning in winter, and the wound can not be healed for a long time, which is easy to induce frost injury. and easy to cause the attack of canker disease.

2. Types of kiwifruit trees prone to freezing injury

The main results are as follows: 1. Young seedlings have poor resistance, not many nutrients, and are easy to suffer frost injury.

2. Fertilizing and watering or using too many chemical hormones will empty the tree, so that the tree can not withstand the freezing damage.

3. Diseased trees with diseases such as root rot and yellowing have poor resistance and are prone to frost injury; fourth, for trees that hung too many fruits in those years, the nutrients of kiwifruit trees were absorbed too much, resulting in severe overdraft and becoming weak trees. Their resistance is greatly weakened, and they are more vulnerable to cold and cold.

All right, friends of growers, in the explanation of today's article, we talked about several key points of preventing frost damage of kiwifruit trees in winter, and some prevention and solutions.
