1. Orchard irrigation. Pour 2 or 3 times of water before sprouting. The flowering period can be postponed by 2 to 3 days. After the budding of fruit trees, watering can be delayed for 3 to 5 days. If the spout is sprayed on the fruit trees with a two-minute spray and two-minute pause before the low-temperature frost, the flowering period can be delayed by more than 10 days.
2. Smoke smoke. When the temperature falls to 0°C at night, igniting the smoke in the orchard can increase the temperature of the environment, effectively reducing its freezing damage. Each orchard orchard should discharge 4 to 6 cigarettes.
3. The trunk is painted white. The use of a whitening agent in the spring to whiten the fruit branches can effectively reduce the absorption of solar heat and delay fruit sprouting and flowering for 3 to 5 days.
