Key Points for Rice Cultivation Management During Spring Cold Waves
I. Characteristics of Cold Wave Disasters Due to the invasion of cold air, when the temperature drops sharply by more than 10°C within 24 hours, and the minimum temperature within that day is below 5°C, it is called a cold wave. In the middle and lower reaches of the Yangtze River, when strong cold air moves southward and causes the temperature to drop by more than 10°C within 48 hours, it is also called a cold wave. Cold waves generally occur in spring and autumn, with spring being the most common, and spring cold waves mostly occur from March to May. Cold waves mainly cause seed rot, seedling rot and dead seedlings during the rice seedling stage. II. Rice Cultivation Manage
