How to prevent chrysanthemum freezing
The low price of frozen chrysanthemum will greatly affect the income. Chrysanthemums are harvested during the frost period until the beginning of winter. Chrysanthemums are related to the coldness of the frost, weakening or preventing the cold current, making it difficult to prevent frost formation. First of all, we must know when the cold has arrived. We must pay attention to watching or listening to the weather forecast before and after the frost falls. We must be ready to hear the cold weather. From 5am to 7am, guarding at the side of the chrysanthemum field, this time is the time for the frost, and there will be a cold flow before the frost. The cold wind and the biting bone are very sensible, usually based on the north wind. Immediately lit the firewood placed on the north side of the chrysanthemum field, that is, the upwind outlet, so that a layer of smoke in the chrysanthemum field can effectively prevent frost. This cold stream lasts for more than ten minutes. Be sure to grasp the timing. If it is too late, it will be ineffective. If there are many cold currents, smoke a few more smoke until harvested.
