According to the monitoring and forecast of the China Meteorological Administration, there will be scattered showers or thunderstorms in the northern winter wheat area around April 29, with a cumulative rainfall of 5 to 15 mm. The shallow soil moisture will be supplemented to facilitate spring sowing; There is basically no precipitation in central and northern Shanxi, and drought in some areas is not good for spring sowing. In the northeast region, there will be a windy and cool weather process from April 30 to May 1, but the cooling range is limited, and the thermal conditions are generally favorable for spring sowing. At present, the spring maize in the northeastern region, the eastern part of the northwestern region, the north China, the Huanghuai, the Jianghuai and the Jianghan region are in the sowing and emergence stage, and the cotton in the Yellow River Basin and the middle and lower reaches of the Yangtze River are in the sowing period. From April 29 to May 1, most of the northeastern region has 10 to 25 millimeters of rainfall, with rainfall in some parts of the southeast reaching 25 to 50 millimeters. Most of the northeastern region is suitable for spring, which is conducive to spring sowing; the soil in the eastern part of Heilongjiang and northeastern Jilin will continue to be too wet, which is not good for spring maize sowing.
Make the following suggestions:
1. Most of the northeastern regions should plant spring corn in time; the eastern region should pay attention to soil diversion and avoid soil over-wetting to affect sowing.
2. The eastern part of the northwestern region, North China, and Huanghuai and other places should seize the favorable opportunity of this precipitation, sowing spring corn and cotton; in areas where soil dryness and drought persist, attention should be paid to timely planting and sowing.
