With the change in weather, most farmers have started their spring plowing and planting activities. From March to April each year, the region is particularly vulnerable to a phenomenon known as "cold spring," which can bring sudden temperature drops and frost. Recently, technical staff from the Agricultural Technology Service Center in Xiyong Town, Shapingba District, visited local farms to provide guidance on how to effectively prevent cold damage and protect vegetable crops from frost.
It has been reported that "cold spring" conditions can cause varying degrees of frost injury to young seedlings, fruit vegetables grown in greenhouses, and early-season vegetables in open fields. This can lead to losses such as rotting, plant death, and premature fruit drop. Therefore, it's crucial for farmers to remain vigilant and take preventive measures as soon as possible to minimize potential damage.
Director Ma from the Xiyong Town Agricultural Technology Service Center visited a field shed to personally advise the farmers. He emphasized that during frosty nights, many farmers tend to use traditional methods like burning smoky materials to create a protective smoke screen. However, he reminded them that the placement of these smoky spots should be carefully planned so that the smoke can cover the entire farm area effectively. The best time to light the smoke is between midnight and 2:00 a.m., ensuring that the smoke screen remains active until sunrise. This method has proven to be one of the most effective ways to shield crops from frost damage.
In addition to this, farmers are encouraged to monitor weather forecasts closely and prepare additional protective measures, such as using mulch or covering plants with blankets when necessary. By combining these strategies, farmers can better safeguard their crops and ensure a successful growing season despite the unpredictable weather.
