1. The wheat in the winter wheat area has entered the jointing growth stage, and the water demand is gradually increasing. The rainfall at this time is conducive to the growth of northern wheat. The heavy rainfall in the south of the Yangtze River will cause the soil moisture to be too large. The local areas need to strengthen the field management, pay close attention to the accumulation of rainwater in the field to prevent waterlogging.
2. Jiangnan South China needs to do the post-rain drainage work of vegetable fields, strengthen the management of rape fields, pay attention to clearing the ditch and reduce the humidity in the field, and at the same time seize the favorable opportunity to apply the rapeseed flowering and pod-forming fertilizer.
