According to the Guangdong Provincial Meteorological Bureau, the tropical disturbance originally located in the central and eastern parts of the South China Sea developed into a tropical depression on the morning of the 19th. In the central South China Sea about 600 kilometers southeast of the Xisha Islands, the maximum wind power near the center is 7 meters, reaching 16 meters. The wind speed per second (equivalent to 58 km / h), the central minimum pressure of 1002 hectopascals. Linyi Fertilizer Network Copyright

It is expected that the tropical low pressure will move to the northwest in the next 24 hours at a speed of about 10 kilometers per hour, which may be strengthened into a tropical storm and gradually approach the sea surface in the northern part of the South China Sea. Affected by the tropical depression, the winds in the central South China Sea will be level 6 to 7 in the next 24 hours. Linyi Fertilizer Network Copyright

In the next three days, Guangdong Province is in an unstable region with high altitudes. Showers and thunderstorms are more obvious, but sunshine is strong, and the highest temperatures in some cities and counties will exceed 35 °C. Among them, from 19 to 21, there were showers or thunderstorms in the western part of Guangdong and the Pearl River Delta, scattered showers in other places, and high temperature in the central and northern parts. From 22 to 23, there were heavy rains and heavy rains in the central and southern parts of the province, and some heavy rains and heavy rains. There are scattered showers or thunderstorms in the north. Linyi Fertilizer Network Copyright

It is suggested that mature early rice, peanuts and lychee should be harvested in advance to avoid or mitigate the losses caused by strong wind showers; high temperature weather is not good for early rice filling and late rice breeding, and field management needs to be strengthened. Farmers and friends in the field should do a good job in sun protection, heatstroke prevention and cooling, and prevent heat stroke and other diseases. In the early rice production area, water temperature adjustment (such as daytime irrigation, night irrigation, sprinkler irrigation, etc.) or spraying of chemicals can be used to reduce the adverse effects of high temperature on early rice filling, increase the grain weight, and pay attention to prevent high temperature burning of late rice seedlings. Dry vegetables, melons, or seedlings can be used to reduce the damage caused by high temperature by using shade nets, grass laying or sprinkling irrigation. Linyi Fertilizer Network Copyright
