4 key points to remember for preventing freeze damage in kiwifruit trees in winter

In winter, as temperatures continue to drop, kiwifruit growers get busy again for a while, pruning branches and leaves, watering and irrigating, and the problem of preventing kiwifruit trees from suffering freeze damage needs to be solved. The most important part is the freeze protection work. Doing a good job of freeze protection in the kiwifruit orchard in winter will effectively reduce freeze damage.

1. Key points for preventing freeze damage in kiwifruit trees in winter

1. Clear away accumulated snow

Recently, as temperatures continue to fall, snowy weather is about to arrive. After it snows, promptly clear the accumulated snow on the kiwifruit branches and trunks and under the trellis surface. If it is not cleared in time, it will damage the branches and buds and affect budding the following year. After clearing the accumulated snow on the trellis surface and around the lower part of the roots and stems, you should also combine this with mounding soil for freeze protection.

2. Keep the trees warm

Dry corn stalks can be used to keep the tree warm. If corn stalks were not prepared in advance, you can also use cotton clothes kept at home that are no longer worn, or other materials with good breathability and warming properties, to wrap the tree. The wrapping height should be greater than 1 m. If continuous low-temperature snowy weather occurs, you can use Kuifuling + Wofengsu + brown sugar + organosilicon to brush the trunks.

3. Trunk brushing treatment

Use biological fungicidal smear + plant nutrients + brown sugar + organosilicon to brush the trunks, and at the same time spray with biological fungicidal smear + plant nutrients + brown sugar + organosilicon + potassium sulfate + calcium nitrate. Re-brush those trees prone to freeze damage 3 times. The first brushing repairs wounds, the second kills potentially hidden fungi, and the third adds nutrients and enhances the tree's cold resistance. Sugar substances, while improving tree nutrition, also increase the content of soluble sugar in tree cells, thereby lowering the tree's freezing point. This gives the tree stronger low-temperature resistance.

4. Prune branches

Choose not very cold weather to prune kiwifruit branches. About half of the branches need to be pruned during the growing season, not all at once in winter. Winter is the dormant period of kiwifruit trees. Pruning branches in winter is less workable than pruning during the growing season, because kiwifruit trees stop growing in winter, and after pruning, the wounds cannot heal for a long time, which not only easily induces freeze damage but also easily causes canker disease.

2. Types of kiwifruit trees prone to freeze damage

1. Young seedlings have poor resistance and not many nutrients, and are prone to freeze damage

2. Too many rounds of fertilizing, watering or using chemical hormones will force the tree to become hollow, and such trees are even less able to withstand freeze damage

3. Diseased trees with root rot, yellowing and other diseases have very poor resistance and are also prone to freeze damage; fourth, trees that bore too much fruit in the same year, because too much fruit was borne, the nutrients of the kiwifruit tree were also absorbed too heavily, causing serious depletion of the tree, turning it into a weak tree, greatly reducing resistance, and making it more susceptible to cold and freezing
