摘要
本文根据吉林省20年（1981～2000）的气象资料，应用Y．M．安格斯坦提出的土壤干湿指标，分析了吉林省通化、长春、农安、四平、白城地区小麦生长期内土壤干湿程度状况。分析的结果表明：通化地区土壤水分能够满足小麦生育阶段生长的需求；长春、农安、四平地区自上世纪90年代以来，出现土壤干旱情况的频率增加，需要采取适当的灌溉措施；白城地区春季频繁干旱．小麦种植需依赖灌溉，由于水资源紧张，所以不宜发展小麦种植。
This paper analyzed the status of soil moisture in farmland of wheat of five areas about the area of Tonghua, Changchun, Nong, an, Siping, Baicheng in JiLin province and how well it was suitable to the need of water in breeding period based on climatic data from 1981 to 2000. The index of Soil Moisture advanced by Y. M. Egastein has been used on the paper. The results showed that the need of water in breeding period can be met by soil moisture in Tonghua. As the frequency of drought was increasing in Changchun, Nongan and Siping from 1990s, irrigation methods should be improved. The water for the growth of wheat depended on irrigation in Baicheng and because the water resources was in tight situation, it is always dry in spring so it was not appropriate to plant wheat in this area.
