In winter and spring, vegetable snow damage is very common. In case of heavy snow and continuous snowfall, snowstorms will occur greatly. The exposed vegetables will be buried or the sheds will be crushed, resulting in a large reduction or no harvest, impacting the supply of vegetables and pushing vegetables. The price, therefore, the vegetable farmers should pay great attention to this.
Prevent vegetable crops from being frozen and harvest early. Control watering and top dressing to reduce humidity and avoid prolonged growth. If it is a warm vegetable, you can spray a new high-fat film and take a small arch shed; if there is more cooling, the nursery shed will be covered with a small arch shed to protect the cold.
In the case of continuous snowy weather, the reflective curtain can be hung, the light can be supplemented and heated, and the photosynthetic nutrient film fertilizer can be sprayed to help the growing vegetables absorb the light energy and improve the fertilizer efficiency, and the wind should be released when the snow stops at noon. Snowfall during the day, if the temperature is not very low, you can not fall into the grass. If the temperature of the shed does not drop, you should extend the time of seeing light. If the temperature is low or snowfall at night, the grass should be dropped and covered with shed film to prevent wet grass.
Strengthen management, promote the rejuvenation of seedlings, carry out the cultivating, raise the ground temperature, and gradually increase the temperature of the shed. Spraying vegetables with strong stems and vegetables can make plants stems strong and improve their ability to resist disasters. For example, the weather in the rainy and snowy weather is long, and when the snow is suddenly clear, pay attention to the gradual uncovering in a few days to avoid the vegetable smashing seedlings. For the weaker shed vegetables, spray a new high-fat film, that is, put the health care transparent clothes on the plants. Insulate germs, improve the ability to resist natural disasters and photosynthesis, and protect plants to thrive.
