As of 8:00 pm on the 12th, some counties and cities in northern Fujian and eastern Fujian have relatively more precipitation, generally 6 to 9 mm, of which Zhangzhou is the largest, 11 mm, and the drought has been alleviated. There is less precipitation in central and southern Yunnan, generally below 4 mm, and the drought is slightly relieved.
According to the investigation of the expert group in the city of Bengbu, the wheat field that was not sown after sowing, not suppressed after the sowing, and not watered before winter, the soil was only wetted by 1 to 1.5 cm, and there was still about 4 cm of dry soil down. The soil moisture content was 9.4% by immediate measurement. Therefore, after the precipitation, the problems of the “problem†wheat field in the central and southern parts of the province still exist, and there are five main reasons for the problems in the wheat field: 1 shallow rotation, extensive land preparation, large amount of shallow soil straw; 2 sowed Shallow; 3 sowing too early; 4 density is too large; 5 poor ground foundation or insufficient base fertilizer. Therefore, the management of this type of problem wheat field still can not be relaxed, and still take active measures to combat drought. This type of wheat field should be watered immediately, preferably with small white dragon watering, and the amount of water should be small. Pay close attention to temperature changes when watering, and predict that there will be cold currents and no watering. After a cold wave has elapsed, water should be watered when the average daily temperature is above 3 °C to ensure that the water is infiltrated on the same day, leaving no clear water to avoid freezing damage. Combined with watering, 7 to 10 kg/mu of urea can be applied to promote early growth and early growth. After watering, it is necessary to plan in time to increase the temperature and ensure the transformation of the seedlings.
è¶å¢’ sowing, high quality of land preparation, post-sowing suppression, soil compaction, unfrozen water in the wheat field, the soil moisture content of 0-15 cm after the precipitation is 12.0%. Although the drought in this type of wheat field has not been lifted, most of the seedlings are better and should not be immediately watered. If there is no obvious precipitation process in the near future, water should be watered after the wheat is returned to green, and 20 kg/mu of urea should be chased in combination with watering.
The sowing time is good, the quality of the land preparation is high, and the wheat field that has been poured over the winter water. After the precipitation, most of the dry soil in the wheat field disappears, and the sensation is good. Do not blindly inject water and topdress.

Although the drought in the wheat field eases the management of water and fertilizer, don't relax.
On February 12th, after the spring rain in the main wheat producing areas of Hebei Province, on February 13th, the “Wheat Drought Expert Service Group†of the Institute of Grain and Oil of the Provincial Academy of Agricultural Sciences conducted the latest developments of rainfall distribution throughout the province and drought conditions in the wheat area after the rain. Follow-up inspection and technical guidance services.
