What temperature requirements does soybean growth have? Detailed explanation of the suitable temperature range

Growing Techniques 0 views
Soybean is a warm-season crop and has different temperature requirements at each growth and development stage. First, seed germination is very sensitive to temperature: the minimum germination temperature is 6°C, emergence is 8-10°C, and seedlings suffer slight frost damage at a low temperature of -4°C. Throughout the growth period, the optimum growth temperature for soybean is a daily average temperature of 20-25°C, among which the optimum growth temperature for seedlings is 20-21°C, the flower bud differentiation stage is 21-23°C, the flowering stage is 22-25°C, the pod-setting and seed-filling stage is 21-23°C, and the maturation stage is 19-

The accumulated temperature required for the entire growth period is generally 2400-3800°C.
