摘　　要：利用NIM插件探测器及金硅面垒探头组装了植物活体水分探测仪;筛选并分析了仪器的最佳工作条件;检测了春小麦、玉米、苜蓿、豌豆、红豆草叶片鲜重的变化。结果表明;叶片水分随时间损失大的,其抗旱性差。叶片保水的秩序为:红豆草、豌豆>苜蓿>春小麦>玉米。The instrument for woater content of living plant was made up of NIM(standard nuclear instrument module)and junction semicoductor detector. The best condition of the instrument was analyzed and chosen. The results indicated that the sequence of preserrating water of leaves was onohrychis pea>lecerne>spring wheat>corn. The greater the water lost, the less the drought resistance
