While snowfall can be beneficial to crops, it significantly impacts Greenhouse. Snow directly affects sunlight exposure within the greenhouse, leading to lower temperatures and causing vegetables to grow slowly or even suffer frost damage.
1. Timely Planting and Marketing: For Commercial Greenhouse susceptible to frost damage, timely planting and marketing are crucial to minimize snow-related losses.
2. When growing vegetables in open fields, promptly clear ditches, drain standing water, lower the water table, reduce root damage to the environment, and promote healthy root growth. This helps improve the cold resistance of Greenhouse.
Take measures such as covering with small arched tunnels, mulch, dry straw, and applying a thin layer of ash to the leaves for frost protection.
Combined with tilling and hoeing, remove withered leaves and apply a one-time top dressing of 0.2% potassium dihydrogen phosphate and 0.2% urea to the roots and stems.
