In summer, it is hot and rainy, and it is prone to continuous rainy weather. Long-term continuous rainy weather will make crops appear ill, withered, and cracks in fruits and many other adverse reactions. Therefore, the following issues should be noted:
1. Dispose of water in the field according to local conditions, fix the fallen crop while supporting the soil while draining, and wash away the surface mud to facilitate photosynthesis and promote plant growth.
2. Pay attention to the prevention of pests and diseases. Because continuous cloudy days have long duration, high humidity, and lack of light, which are conducive to the growth of pests and weeds, timely prevention and control of pests and diseases should be carried out and pesticides should be promptly sprayed.
3. Apply nutrients in time after rain, and apply appropriate amount of available nitrogen fertilizer to the flooded crops to supplement the lack of nutrients caused by rain leaching, ensure the supply of fertilizers, and promote the plants to restore robust growth as soon as possible.
Finally, we must pay attention to: Topdressing nitrogen and potassium fertilizers should be covered with soil to avoid nitrogen loss during hot and rainy seasons.
