The drought in Huibei is alleviated, and the balance of water supply and demand in farmland

The meteorological indicators of agricultural droughts and floods calculated according to the temperature and precipitation data of 78 stations in Anhui Province indicate that there were different degrees of drought in most areas north of Hefei in early June 2011, including heavy drought along the central and western parts of Huaihuai, and most of the south of Hefei. Light to heavy, there are specialties in southern Fujian, which is not good for growing crops in the area.

Analysis of temperature and precipitation conditions from the previous period and the first ten days: In May, except for the beginning of the month, the end of the first month to the beginning of the first half of the year, and the beginning of the first half of the year, there were precipitation processes in most of the other periods. Precipitation continues to be less and less, and most areas in Jiangbei maintain different degrees of drought, which is unfavorable for the normal growth of spring-sown crops and rice transplanting in the seedling stage, but the sunny and hot weather is conducive to the harvesting of wheat and rapeseed. In the first half of June and the end of the first half of Anhui Province, there was a distinct rainfall process, resulting in oversupply of farmland in most areas south of Hefei, with light to severe waterlogging, which had a certain impact on the growth of spring-sown crops, but was planted in a season. The plug provides plenty of moisture. In most areas north of Hefei, there is basically no effective precipitation. Most areas maintain light to moderate drought, and some areas have heavy drought, which affects the summer planting.

According to the weather forecast issued by the Provincial Meteorological Observatory in mid-June 2011, in the case of normal precipitation in Jiangbei and 2 to 50% in Jiangnan, the average temperature in the whole province is normal. It is expected that the supply and demand of farmland water in the north of Hefei will be basically in mid-June. Balance, the south of Hefei has light to heavy.
