Recently, most of the southern part of China has more precipitation. In the next few days, precipitation and strong convective weather are obvious. It is necessary to guard against local heavy rainfall and its urban-rural accumulation, mountain torrents, landslides and other disasters.

Agricultural advice
Recent rainfall and strong convection have become the most important weather processes in most parts of the South. Heavy rainfall and strong convective weather have caused some areas to be affected. Local areas need to strengthen field management and timely spring work. The winter wheat area and the northeast spring sowing area will have precipitation in the next three days, and there will be more windy weather. Watering and fertilization should be carried out in a timely manner, and low-temperature freezing damage should be prevented. The facility vegetables should be reinforced in time to avoid windstorms.
Based on the meteorological weather forecast and combined with the current agricultural situation, the following recommendations are made:
1, strong convective weather will affect the growth of rice seedlings, rapeseed, flue-cured tobacco and other crops and tea gardens, orchards, is not conducive to rapeseed flowering pods and early rice sowing. All localities should pay attention to the weather forecast, arrange the farming affairs reasonably, strengthen the field management and clear the ditch, and ensure the smooth progress of spring sowing and the normal growth of crops.
2. Most winter wheat will enter the jointing stage, and the winter wheat will enter a vigorous growth stage after jointing. Therefore, all localities should promptly check the wheat field sensation, timely watering and fertilizing, promote the stable growth of winter wheat, and reduce the number of infertile spikelets.
3, the future cold air activities are frequent, the temperature rises unsteadily, all localities should pay close attention to the weather changes, and do a good job of defense against night frost damage to prevent winter wheat or fruit tree buds from freezing. There are many windy weather, and the facility vegetables should be reinforced in time to avoid mechanical damage.
