According to the National Meteorological Center, in the first half of June 2011, cotton in the Xinjiang, Yellow River Basin and Yangtze River basins were in the fifth true leaf to the bud stage. The photothermal conditions in the northwest, north China and Huanghuai areas are good, which is beneficial to the growth of cotton seedlings. Jianghuai, Jianghan, and central and northern Jiangnan showed two obvious precipitation processes on the 3rd to 6th and 9th to 10th, respectively. The precipitation in the southwestern part of the Yangtze River, the eastern part of Jianghan, and the southern part of the Yangtze River reached 50 mm or more, and 100~ in most areas. 300mm, the drought has been alleviated, and the precipitation is conducive to the growth of cotton, but some areas such as Hunan, Hubei, Jiangxi and other provinces have experienced severe storms and floods, causing some farmland to be flooded. The precipitation in the northwest of Jianghan and the northern part of Jianghuai is less than 10 mm, and the drought continues.
It is estimated that in the next 10 days (12-21 days), there will be more rainwater in the middle and lower reaches of the Yangtze River. The main rainfall period will be 12 to 17 days. The total rainfall is generally 40-90 mm, and some areas in the northern part of the Yangtze River are 120-240 mm. Local areas can reach 260-300 mm; precipitation will benefit the growth and development of dryland crops such as cotton; however, rainfall in some areas is too large, and heavy rains in some areas will affect agricultural production. In the next 10 days, the northwestern region, the north China, the Huanghuai wheat harvest area will have fine weather, and there will be more obvious rainfall on the 18th to 21st, and the soil moisture will be improved, which is conducive to summer planting.
