| 摘 要： | 土壤水是水资源的组成部分，是农作物的主要水资源。徐州湖西平原地区的土壤水资源为600mm／a。对农作物不同生育阶段有效降水量和耗水量的计算表明．小麦和棉花是普遍缺水的．必须灌溉；玉米生长期内降水较多，一般不须灌水。土壤水资源的管理必须引起重视．并提出土壤水资源管理的几点措施。

| Abstract: | Soil water is part of water resources and the main ones needed by crops. This paper analyses the concept and characteristics of soil water resources, estimates thase in Huxi plane of Xuzhou,which is 600 mm/a. According to the calculation of effective precipitation and crop evapotransipiration in different growing periods,wheat and cotton are deficient in water .irrigation is neces-sary and that the amount of precipitation in growing period of cron is great,irrigation is generally un-necessary. Some menaging methods of soil water resources are brought up. |
