摘要：

为了探讨白浆土大豆需水特点，笔者在2009—2010年采用全土层白浆土盆栽试验，研究了在白浆土特定环境条件下，大豆的耗水特征。结果表明，随着不同处理给水量的增加，大豆株高、单株干重及叶面积增加，且随生育时期推进，增幅加大；光谱反射曲线在红光及近红外光内差异明显，以1200 mm值最高；光合速率和蒸腾速率也随给水量增加而呈明显的上升趋势。综合可知，大豆各项生理指标以800~1000 mm给水处理表现最佳。

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.
