Abstract:
In order to investigate the water demand characteristics of soybean in albic soil, water consumption of soybean in specific environment of albic soil was studied with pot experiment of entire ablic soil layers in 2009-2010. The results indicated that: with the increase of water supply quantity of different water treatments, the soybean plant height, dry weight per plant and leaf area were all increased. Their increase ranges were increased with the development stages. The spectral reflectance curves were significant differences in the red and near infrared light, which reached maximum value in 1200 mm. The photosynthetic rate, transpiration rate were also showed an increase trend with the increase of water supply quantity. The 800-1000 mm water treatment was the best in synthesized performance of soybean physiological indexes.
