Anhui Province is in the critical period of wheat growth and development, and all regions need to catch favorable weather and timely topdressing

According to the Anhui Meteorological Science Research Institute, according to the agricultural meteorological conditions, satellite remote sensing seedling monitoring, ground seedling dynamic monitoring information, socio-economic factors and the results of the winter wheat main production market meeting and production forecasting model since the winter wheat planting in Anhui Province , It is estimated that the winter wheat yield in the province in 2010 is flat compared with last year, compared with the average of the past five years. Provincial Agriculture Commission, according to preliminary statistics, the province's 2010 winter wheat acreage increased slightly compared with last year, compared with nearly 5-year average increase of 5.9%; the province's total output of winter wheat in 2010 compared with last year as a non-leap year, and nearly The average of 5 years is a good year.

At present, winter wheat in Anhui Province is generally in the jointing and booting stage. The overall advantages and disadvantages of agrometeorological conditions since winter wheat planting have been comparable. There have been several severe weather processes since sowing. For example, the drought in the sowing period affects the sowing and emergence of wheat ; the low temperature and cold in the emergence period and the low temperature and rain in the south of Hefei in the wintering period affect the safe wintering and recovery of wheat, which leads to the general delay in development; booting stage temperature ups and downs, and more cold and rainy, spring wheat affect hair and Changchun. The agro-meteorological conditions in the remaining periods are basically favorable. At present, the wheat seedlings in Huaibei are basically normal, which is equivalent to last year. The seedlings south of the Huaihe River are generally weak.

Future weather trends and production recommendations

According to Anhui Province Center for Climate Prediction: mid-April - early May, the province was more than normal rainfall, average temperature near normal. The extreme minimum temperature is 1 to 3 °C in Huaibei and the mountainous areas of the province , and 3 to 5 ° C in other areas . The main cold air activities affecting our province are generally in the middle of April , the middle of April and the early May .

According to the latest forecast of the Anhui Meteorological Observatory: From the 16th , the temperature in the province will rise significantly. There was another precipitation process in the province around the 19th . Therefore we recommend: April temperature changes significantly, all localities should pay close attention to weather changes in a timely manner remedial work after the frost disaster in the cold air. At present, it is a critical period for wheat growth and development, and all localities must seize favorable weather and timely topdressing. At the same time, for the fields where the soil moisture continues to be high, it is necessary to continue to do a good job in clearing the ditch and promoting the steady growth of the seedlings. April is the peak period of wheat scab, early field humidity, moisture provides conditions for the occurrence of scab, late after the temperature rose, hot and humid microclimate environment easily lead to the occurrence of wheat scab epidemic. Therefore, we must pay attention to the monitoring and prevention of wheat scab.
