Anti-freezing measures of kiwifruit in winter

The temperature continues to drop in winter, when kiwifruit planting comes to a busy period, pruning, watering, and the most important thing is anti-freezing work. Only when the anti-freezing work is done well in winter, can we effectively reduce frost damage and ensure the yield and quality of the coming year. So how to prevent kiwifruit from freezing in winter? Come and have a look with the editor.

1. Clear the snow

As the temperature drops, it is snowing in many areas, and after snowing, the snow on the kiwifruit branches and under the shelf is needed in time. If it is not cleaned up in time, it will cause damage to the branches and buds of kiwifruit and affect the sprouting of the following year. After cleaning the snow on the shelf surface and the lower part of the rhizome, it is also necessary to cultivate the soil at the root, which can increase the ground temperature of the root system by 1-2 degrees and prevent the root from freezing, which is an important measure to prevent kiwifruit from freezing.

2. Package to keep warm

After clearing the snow, the next step is to warm the trees, which can be planted with corn stalks. If there is no corn stalks, you can also wrap them with cotton clothes that are not used at home or other materials that are breathable and warm. The height of the package should be more than one meter, which can also play an excellent role in anti-freezing. In case of continuous low temperature and snowfall, Kuaikuling + Wofengsu + brown sugar + organosilicon can be used to coat trees.

3. Tree brushing treatment

Biological germicidal smear + phytonutrient + brown sugar + organosilicon can be used for tree brush drying, with biological germicidal coating + phytonutrient + brown sugar + organosilicon + potassium sulfate + calcium nitrate spray. For those plants that are extremely prone to freezing injury, they should be re-brushed 2-3 times, the first time can play the role of wound repair, the second time can eliminate hidden bacteria, the third time can increase nutrients and enhance the cold resistance of plants. In addition, sugars can not only enhance tree nutrition, but also increase the content of soluble sugar in tree cells, reduce the freezing point of trees, and make plants more tolerant to low temperature.

4. Pruning

In winter, plants should be pruned when the temperature is not very low, or in sunny weather. About half of the branches can be pruned in the growing season, without the need for one-off pruning in winter. During the dormant period of kiwifruit in winter, pruning is not as operable as pruning in the growing season, because kiwifruit stops growing in winter, the wound can not be healed for a long time after pruning, it is very easy to freeze, and it will cause canker disease.

The above is the introduction of kiwifruit winter anti-freezing measures, hope to help you, want to know more related knowledge, please pay attention to us.
