摘　　要：为研究燕麦的抗旱栽培技术,本研究以皮燕麦‘冀张燕5号’为试验材料,对不同水分梯度下燕麦喷施S-诱抗素和黄腐酸,通过测定燕麦株高、叶面积(系数法)、干物质积累量(称重法)、脯氨酸含量(酸性茚三酮法)、可溶性糖含量(蒽酮比色法)、可溶性蛋白含量(考马斯亮蓝法)、超氧化物歧化酶(SOD)活性(光下还原法)、过氧化物酶(POD)活性(愈创木酚法)及过氧化氢酶(CAT)活性(紫外吸收法)等指标,利用显著性分析及隶属函数法进行综合评价。结果表明:喷施S-诱抗素和黄腐酸能提高皮燕麦的抗旱性及产量,正常供水情况下,产量分别比对照提高27.04%和9.21%;中度胁迫下,产量比对照提高25.65%和18.13%;重度胁迫下,产量比对照提高37.11%和21.10%。正常供水情况下,喷施S-诱抗素效果优于黄腐酸,受到水分胁迫时,喷施黄腐酸的效果优于S-诱抗素。To study the drought-resistance cultivation technology, the oat variety‘Jizhangyan5’was used as material, S-abscisic acid(S-ABA) and fulvic acid were sprayed to oats under different moisture gradients. A series of indexes were determined, including oat plant height, leaf area(coefficient method), dry matter accumulation(weighing method), proline content(acid-triketone process), soluble sugar content(anthrone colorimetry), soluble protein content(Coomassie bright blue method), superoxide dismutase(SOD) activity(under-light reduction method), peroxidase(POD) activity(guaiacol method), catalase(CAT) activity(ultraviolet absorption method). A comparative evaluation was conducted with significance analysis and membership function method. The results showed that both S-ABA and fulvic acid improved drought resistance and yield of oat. Under normal water supply, the yield of oat increased by 27.04% and 9.21%,respectively, compared with the control. Under moderate drought stress, the yield of oat increased by 25.65%and 18.13%, respectively. Under severe drought stress, the yield of oat was raised by 37.11% and 21.10%,respectively. Under normal water supply, the effect of spraying S-ABA was better than that of fulvic acid, while under drought stress, the effect of spraying fulvic acid was better than that of S-ABA.
