The influence of cold dew solar terms on agriculture;
1. Growth and development of crops: The temperature drops obviously in the cold dew solar term, which will hinder the growth and development of crops to some extent. During the cold dew period, the growth rate of some crops will obviously slow down, and even the phenomenon of stiff seedlings will appear, which will lead to the extension of crop growth period and further affect crop yield and quality.
2. Occurrence of crop diseases and insect pests: The low temperature environment in the cold dew period is conducive to the reproduction and spread of germs and pests. Low temperature environment will break the dormancy of some pests and make them enter the breeding period ahead of time, which provides conditions for large-scale outbreak of pests. At the same time, the low temperature and high humidity environment in the cold dew period is also conducive to the propagation and spread of pathogenic bacteria, which is easy to cause some crop diseases, such as rice sheath blight and rice blast, and has a great impact on crop growth and yield.
3. Release of soil nutrients: Low temperature will slow down the release of soil nutrients during cold dew. At low temperature, the decomposition rate of organic matter in soil will slow down, resulting in insufficient release of soil nutrients, which will further affect the nutrient absorption and normal growth of crops.
