Temperature requirements for the growth and development of soybean

Published: 2024-11-22 Author: mysheen
Last Updated: 2024/11/22, Soybean is a temperature-loving crop. The accumulated temperature of soybean varieties in Heilongjiang Province is about 1800 ℃. The main results are as follows: (1) the optimum temperature for seed germination is 18 ℃ 20 ℃, at which time the germination is fast and the seedling is uniform; the lowest temperature is 6 ℃ 8 mol, but it is very slow; when the temperature reaches 33 ℃, the germination is the fastest, but the seedling is weak. (2) the lowest temperature needed for seedling emergence is 8 Mel 10 ℃. (3) it is suitable for flower bud differentiation to be 21 ℃ 23 min. It is suitable for 22 ℃ to blossom. The temperature is too high or too low to blossom less. (4) suitable for root growth.
