What are the main meteorological disasters that affect sericulture production?

South silkworm area: there are low temperature, frost and continuous rainy weather in spring and autumn, and local disasters such as typhoon, flood, hail and tornado in summer. Drought, high temperature and heavy rain are common disastrous weather in South Silkworm Area. In addition, there are many strong winds in coastal areas every year, which is not conducive to the cultivation of mulberry seedlings.

In the northern silkworm areas, natural disasters such as low temperature, frost, strong wind and dry-hot wind will do harm to the buds, leaves, branches and even trunks of mulberry trees, ranging from leaf damage to death (especially young mulberry). Disaster weather such as waterlogging, drought and high temperature will cause mulberry stunting, mulberry leaves wither, affect the growth and development after eating leaves, and silkworm bodies are prone to diseases. When strong winds and typhoons appear, trees will even be uprooted, so natural disasters should be prevented in silkworm areas.
