Take off the veil of the sun, and the freezing rain will fall like diamonds, as beautiful as a fairyland. However, behind this beauty lies a serious challenge! In the spring of 2024, one after another freezing rain hit most provinces across the country, bringing a series of problems to agricultural production and also bringing a lot of trouble to farmers.
Freezing rain is one of the common forms of precipitation in winter, which causes falling water droplets to freeze quickly when they come into contact with objects due to the interaction of low temperature and atmospheric humidity. This freezing precipitation can have the following effects:
Destruction of crops: Freezing rain will quickly solidify when it touches the surface of crops, forming ice to cover crops, causing mechanical damage to crops, resulting in losses such as leaf collapse and branch breakage. Hinders photosynthesis: Freezing rain covers the leaves of plants, blocking the normal exposure of sunlight, causing plants to not be able to photosynthesize adequately, thus affecting their growth and yield. Destruction of infrastructure: The ice formed by freezing rain not only causes harm to plants, but also causes damage to the infrastructure of the farmland, such as blocking the drainage system, leading to problems such as water accumulation and soil stagnation.
In the face of the challenge of freezing rain, there are some coping strategies we can adopt to help farmers better protect their crops and farmland.
Early warning: Strengthen the weather monitoring and early warning system, grasp the dynamics of freezing rain and the possible impact range in advance, and issue early warning information in a timely manner to prepare for response. Strengthen greenhouse covering: Before the onset of freezing rain, the greenhouse coverage can be increased, effectively isolating the direct contact of ice and rain to the crops, and reducing losses. Proper drainage: After freezing rain, it is necessary to clean up the stagnant water in the farmland in time to ensure smooth soil drainage and reduce the adverse impact of soil moisture retention on crop growth. Strengthen fertilizer supplementation: Freezing rain will lead to a decrease in nutrient uptake by crops, so it is necessary to increase the supply of fertilizer to help crops better resist frost damage and resume growth. Choose cold-resistant varieties: Planting crop varieties with strong cold resistance can increase the resistance of crops to freezing rain and reduce the risk of loss.
The threat of freezing rain to agriculture cannot be underestimated, but its impact on agriculture can be reduced through prevention, prevention and response. Farmers should always pay attention to weather changes, be prepared to deal with them, make rational use of scientific and technological means and agricultural experience, improve the resistance of crops, and ensure the stability of farmland production.
