How to prevent crop frost damage through weather forecast
Preventing crop frost damage through weather forecast is an important agricultural management task. The following are some preventive measures summarized based on search results:
Pay attention to weather forecast
Agricultural producers should pay close attention to weather forecasts so that they can take preventive measures in time when abnormal weather occurs to reduce the damage of low temperature to crops.
Improve agronomic cultivation measures
Strengthen covering, keep warm and prevent frost
Before the evening when the temperature is low, use materials such as straw and plastic film to cover crops to block frost, increase ground temperature and prevent frost damage.
Clear ditches and prevent water logging
Clear drainage ditches in time to prevent water accumulation in the field and avoid secondary frost damage caused by collapse of greenhouse film or melting of snow.
Prune dead branches and prevent diseases in time
Vegetables are prone to diseases after freezing. Fumigants can be used in the greenhouse for disinfection, and dead branches can be pruned in time to prevent the occurrence of diseases.
Harvest in time to reduce frost damage losses
Harvest vegetables that meet commodity standards in time before the disaster occurs to reduce the yield losses that may be caused by the disaster.
Using antifreeze to keep warm
Using antifreeze containing clinical acid, seaweed polyacrylamide and other ingredients can stimulate the crop's own immune system, resist cold and stress, promote crop root growth, prevent root diseases, improve crop quality, and increase crop yields.
Through the above measures, agricultural producers can effectively use weather forecast information, take corresponding preventive measures, reduce the occurrence of crop frost damage, and ensure the safety of agricultural production.
