Kiwi enjoys a warm and humid climate, and it is most afraid of budding late bloom and late spring. At this time, if there is frost damage, it will often cause kiwifruit shoots, buds, and leaves to be frozen. The light will grow weaker, reduce production, and severe harvests will be rejected.

Smoke smoke method. In the direction of the orchard's upper hand, every 15 meters or so, a smoke release point is set up. The raw material for smoking can be composed of wet wheat bran, straw, deciduous, and weeds. When the temperature drops to about 1 to 2°C in the early morning, it can ignite.
