The effects are as follows:
1. Affects photosynthesis and respiration: higher temperatures during the day are conducive to photosynthesis and can accumulate more nutrients; low, crop respiration is weakened and energy consumption is low, which promotes nutrient storage.
2. Promote crop growth and nutrient synthesis and accumulation: Appropriate temperature difference between day and night can promote crop growth and metabolism, increase yields, and improve nutritional quality and stress resistance . and crop adaptability.
3. Increase crop resistance to diseases and insect pests: Improve plant immunity, make them more resistant to diseases and insect pests, and reduce the use of pesticides.
