摘要
本文根据１９９２－１９９４年三年的试验数据，研究了在黑土特定环境条件下，大豆的耗水特征，结果表明，大豆强度最大时期为开花－鼓粒期，阶段耗水量相当于总耗水量的５０％，大豆耗水量在旱作农区，主要受到降水量的影响，耗水量年际间的差异，也是降水量年际间的差异。
Based on experimental data from 1992 to 1994, the study on water consumption feature of soybean has been conducted in black soil region. The result shows that the maximum water consumption of soybean occurs between flowering and pod swelling; the amount of water consumption in this phase accouts for 50% of the total. In arid farming region, water consumption of soybean is maily determined by precipitation; The difference of water consumption amount between years is also that precipition between years.
