The cold damage of the forest fruit seedlings is caused by the cold winter weather. Freezing damage to seedlings has a great influence on the quantity and quality of seedlings. Some of the seedlings were frozen and the whole plant was dead. Some of the tops of the seedlings were freeze-dried, affecting the survival and growth of the fruit in the following year. In particular, after the summer and autumn drought weather, the growth of seedlings was hindered, relatively thin, and the ability to resist cold was reduced. Therefore, in order to improve the antifreeze ability of seedlings, antifreeze measures should be taken to strengthen seedling management in order to facilitate safe wintering of seedlings. The specific measures are as follows:

The application of P and K fertilizers to promote the lignification of seedlings should be carried out with roots of 0.3% potassium dihydrogen phosphate every 10-15 days from November onwards, with 3 applications, or 200-250 kg per acre with plant ash. Continuously applied 2 times. The nursery will stop applying nitrogen fertilizer after autumn.

Boron sprayed from outside the roots to improve cold resistance. From the beginning of November, 0.5% borax solution was sprayed once every 10 days (also mixed with 0.3% potassium dihydrogen phosphate solution) and sprayed three times.

In winter, the seedlings with weak cold-resistance ability can be buried in the soil for winter, and precious seedlings can be used in anti-freezing greenhouses (greenhouses). Alpine nurseries can be built wind barriers, that is, in the wind surface hanging pine wood branches to withstand the cold wind. A layer of straw or thatch can also be kept warm.

Before the onset of antifreeze frost, watering the nursery can make the soil temperature no lower than 0°C, and prevent the seedlings from freezing.

Smoke, cold, and especially cold weather, can be set around the nursery 2-3 cigarettes, smoke when the temperature dropped to 0 °C, and keep the smoke until sunrise.
