On the 16th, most of Henan Province began a new week with clear weather, and the temperature rose significantly during the day. Today and tomorrow, Henan will continue to be sunny and hot, and most areas will be invaded by dry and hot weather. The agricultural sector needs to be irrigated when there is no strong wind to ensure smooth wheat filling.
According to the Henan Provincial Meteorological Observatory, most areas of Henan will be invaded by dry and hot weather on the 17th and 18th, and the southerly wind will be blown up by 4-5 in the daytime. The maximum daily temperature will exceed 32°C, but the relative humidity will be lower than 30% at 14 o'clock. . The specific forecast is as follows:
On the 17th, the province was sunny to cloudy, with a southwest wind of 4-5, the highest temperature: 32-33 degrees; 14 hours relative humidity: 20-30%.
On the 18th, the province was cloudy with sunny days, about 4 southerly winds, with the highest temperature: 34-36 degrees; 14 hours relative humidity: 15-20%.
At present, most of Henan Province is in the filling stage, especially in the area south of the Yellow River, which coincides with the peak filling period. Experts suggest that the above areas should focus on measures to prevent the adverse effects of dry hot air on the wheat field. For wheat fields with low humidity in the field, water should be poured in the absence of strong winds to increase the humidity in the field. At the same time, chemical agents such as potassium dihydrogen phosphate, zinc sulfate and boric acid should be sprayed in proportion to accelerate the grouting process and nutrient operation. Increasing the dry weight of wheat ears is also an effective measure to reduce the damage caused by dry hot winds to crops.
