What is the effect of millet flowering on yield in foggy and rainy days?

Cross-pollination is often easily limited by environmental conditions, and there is no opportunity for pollination, such as windless pollination, strong wind or low temperature insect pollination, which reduces the opportunity for pollination and fertilization and affects the yield of fruits and seeds. In agricultural production, auxiliary pollination is often used to overcome the defect that pollination cannot be guaranteed due to insufficient conditions and achieve the expected yield. Plants bloom in rainy days.
