The sunny weather in South China is good for early rice growth, and the weather in the middle and lower reaches of the Yangtze River is not favorable for spring sowing.

From late February to early March, it is an important period for early rice breeding in most parts of South China. If the weather is fine and the average daily temperature reaches above 12 °C, it will help the early rice planting and emergence, since the 20th. The temperature in most parts of South China is obvious, the sunshine is sufficient, most of the temperature is above 12 °C, and the precipitation is less. The meteorological conditions are very beneficial for early rice sowing and breeding strong seedlings. At present, most of Guangdong Province in southwestern Guangdong Early rice is in the stage of sowing and emergence, and most of the early rice in Hainan has entered the tillering stage and grows well. Most of southern China has continued to have good weather these days. It is very suitable for seedling emergence and normal growth of early rice. It is expected that before March 4th, the temperature in early rice producing areas in southern China will continue to be above 12 °C, and most of the time will be full of sunshine. It is recommended that the peasant friends here seize the favorable timing of this weather and plant in time to ensure the smooth emergence of seeds. Some early rice producing areas that have been planted and emerged should continue to strengthen the field management of early rice.

However, compared with the sunny weather in the early rice producing areas of South China, the weather conditions in the middle and lower reaches of the Yangtze River are not suitable for spring planting in the next few days. It is expected that from February 28 to March 1, medium-intensity cold air will affect the central and eastern regions. In most areas, the temperature drops by 4-6 °C, and the cooling rate in some areas reaches 8-10 °C. The winds in most parts of the Yangtze River are 4-6. There are 6 to 8 northerly winds in the Bohai Sea, the Yellow Sea and the East China Sea.

From March 2nd to 3rd, there was light rain in the Hanshui River Basin, Jiangnan, western South China and the southwestern part of the country.

Heavy rain will occur in parts of the middle and lower reaches of the Yangtze River.

In the greenhouses in the cooling area, please pay attention to the regulation of temperature and humidity in the shed. In addition, the low temperature and rainy weather with an average daily temperature of ≤12 °C is unfavorable for the spring sowing. Some areas may need to wait for a few more days.
