According to weather forecast in early April, it is recommended that: 1. All localities should make full use of the favorable conditions when the current temperature rises and the weather is relatively stable. The rice and maize planting and seedling raising work should be carried out in a timely manner, and measures for keeping warm should be actively carried out accordingly; field management work focusing on fertilizer and water should be carried out for the Xiaochun crops, and timely. Increase fertilizer application to promote active crop growth and lay a foundation for the formation and improvement of later production. 2. To strengthen the field management of seedlings that have sown rice and timely dismantling seedlings for seedlings; and pay close attention to the changes in the seedlings situation. In the case of crops with dead seedlings, the timely replanting should be considered in case of mistakes. For weaker growing fields, fertilization should be added to promote seedling growth. Since the temperature has fluctuate since 3.3 months, and the humidity in the fields is high, the field environment conditions are very suitable for the occurrence and development of wheat rust and rapeseed sclerotinia. Localities should pay close attention to weather changes, strengthen monitoring, and use favorable weather conditions to further grasp the pests and diseases of small springs. Prevention work to reduce pest damage. 4. All localities should make full use of favorable precipitation conditions, and do a good job in water storage and flood protection in time to provide favorable moisture conditions for the active growth of small spring crops and planting and planting in spring.
