Along the Huaihuai North, precipitation has continued to decrease since October last year, and the drought has occurred and has intensified. The rain and snow weather on February 7-10 temporarily eased the drought along Huaihuai River, but due to the obvious lack of precipitation, the mitigation effect was limited. Since mid-February, along the Huaihuai River, it is still dominated by fine weather, and the temperature has risen remarkably, which has led to accelerated evaporation of soil water, and the drought in the early Huaihe River has increased again.
According to the forecast of the Anhui Provincial Meteorological Observatory, there will be a precipitation process along the Huaihei-Huai area from February 25 to 28, with a cumulative precipitation of 10-20 mm. In addition, from February 27 to March 3, affected by cold air, the temperature in our province will continue to drop by 7 to 9 °C.
The precipitation process along the Huaihei-Huabei area on the 25th to 28th will relieve or alleviate the drought in the dry area and improve the soil moisture, which is conducive to the transformation of winter wheat in the dry area and the normal tillering after greening. As the ability of winter wheat to withstand low temperatures after gradual decline, the cold air at the end of February and early March has an adverse effect on the fast-growing winter wheat. In order to alleviate the yield loss caused by drought to winter wheat, avoid the freezing damage caused by low temperature to winter wheat. All localities must seize favorable weather conditions and do a good job in current field management.
1. There will be significant precipitation along the Huaihei River in the next few days, and the continued drought will be relieved or alleviated. Therefore, irrigation areas that are being irrigated or ready for irrigation can stop irrigation, so as to avoid wasting human and financial resources and causing unnecessary economic losses.
2. For wheat fields with poor soil fertility and small populations, it is necessary to apply fertilizers and supplement nutrients in the rainy season. In the case of drought-heavy fields, it is necessary to re-apply body fat, promote early growth, increase the rate of tillering and increase the number of grains per ear.
3. After winter wheat is returned to green, the cold resistance is obviously reduced. It is necessary to pay close attention to the effects of low temperature freezing damage caused by strong cooling, and seize the favorable opportunity to carry out a repression, so that the wheat roots are in close contact with the soil to enhance the cold resistance of the wheat seedlings and promote root development and nutrient.
