1. Where does the broad bean grow?

The broad bean grows in warm wetlands at 63°N latitude and tolerates low temperatures of -4°C, but it fears heat. Its temperature requirements vary with the growth stage: the suitable temperature for seed germination is 16-25℃, the minimum temperature is 3-4℃, and the maximum temperature is 30-35℃. During the vegetative growth period, the required temperature is lower, with a minimum temperature of 14-16℃, while the flowering and fruiting stage requires 16-22℃. If exposed to a low temperature of -4℃, its aboveground parts will suffer frost damage. Although the broad bean can fix nitrogen from the air through rhizobia, it still needs to absorb large amounts of various elements from the soil for its growth, and nutrient deficiencies often cause various physiological diseases.
