Influence of increased temperature on the yield and quality of broad bean in semiarid regions of northwest China
In this study, a simulation experiment by farm warming with infrared ray radiator was carried out, and results showed that the broad bean (Vicia faba L.) growing days were shortened by increased temperature. The seedling, ramifying, budding, blooming, podding, and maturing stages were shortened by 1–4, 1–2, 1, 2–3, 1–2, and 2–4 days, respectively, and the whole growing period was shortened by 7–16 days when the temperature increased by 0.5–2.0°C. The broad bean yield increased by 10.1–16.6% when the temperature increased by 0.5–1.0°C, and significantly decreased by 38.1–90.1% when the temperature increased by 1.5–2.0°C. Increased temperature significantly improved the fat, carbohydrate, ash and energy contents.
