How to protect kiwifruit from freezing in winter? A detailed explanation of the latest antifreeze measures

As winter temperatures continue to drop, kiwifruit cultivation has entered another busy period, with pruning and irrigation, but the most important task is antifreeze work. Only by doing a good job of antifreeze protection in winter can freeze damage be effectively reduced and the yield and quality of the coming year be ensured. So how should kiwifruit be protected from freezing in winter? Let's take a look together.

1. Clear snow

As temperatures drop, many areas are seeing snow, and after snowfall, the snow on the kiwifruit branches and under the trellis surface needs to be removed in time. If it is not cleared promptly, it will damage the kiwifruit branches and buds and affect sprouting the following year. After clearing the snow from the trellis surface and the lower part of the root crown, the roots also need to be earthed up. Earthing up around the roots can raise the soil temperature at the root zone by 1-2 degrees and prevent the roots from freezing, making it an important antifreeze measure for kiwifruit.

2. Wrap for warmth

After clearing the snow, the next step is to keep the tree warm. Corn stalks can be used to wrap the plants. If there are no corn stalks, unused cotton clothing from home or other materials with good air permeability and insulating properties can also be used for wrapping. The wrapping height should be greater than one meter, which can also provide excellent antifreeze protection. If there is continuous low-temperature snowy weather, a treatment of Kuifuling + Wofengsu + brown sugar + organic silicon can be used to coat the trees.

3. Brushing treatment for the trees

A biological fungicidal coating agent + plant nutrients + brown sugar + organic silicon can be used to brush the tree trunks, combined with a spray of biological fungicidal coating agent + plant nutrients + brown sugar + organic silicon + potassium sulfate + calcium nitrate. For plants highly prone to freeze damage, they should be brushed heavily 2-3 times. The first time can repair wounds, the second time can eliminate hidden pathogens, and the third time can add nutrients and enhance the plant's cold resistance. In addition, sugar substances, while enhancing tree nutrition, can also increase the content of soluble sugar in the tree's cells, thereby lowering the tree's freezing point and making the plant more tolerant of low temperatures.

4. Pruning

In winter, choose weather when the temperature is not too low to prune the branches of the plants; it can also be done in clear weather. About half of the branches can be pruned during the growing season and do not need to be pruned all at once in winter. Winter is the dormant period for kiwifruit. At this time, pruning branches is less workable than pruning during the growing season, because kiwifruit stops growing in winter, and after pruning, the wounds cannot heal for a long time, making them highly prone to freeze damage and also causing canker disease.
