中文摘要	内蒙古长城沿线丘陵地区干旱少雨严重制约作物出苗,导致作物产量低而不稳。腐殖酸作为土壤改良剂具有抗旱保苗效应。基于田间定位试验,本研究分析了施用腐殖酸1~5年对谷子出苗率、干物质积累量、根长和抗氧化酶活性及苗期土壤水分的影响。结果表明:施用腐殖酸处理均提高了苗期0~60 cm土层土壤含水量和土壤贮水量;施用腐殖酸处理显著提高了谷子出苗率、地上部干重、地下部干重、根冠比和根长,增加幅度分别为2.62%~16.53%、3.70%~111.11%、8.21%~ 181.33%、4.22%~ 33.25%和2.00%~ 23.87%;施用腐殖酸处理显著提高了苗期叶片过氧化物酶(POD) 、超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性;施用腐殖酸处理显著增加了谷子生物产量和籽粒产量,增加幅度分别为4.06%~20.65%和0.67% ~ 16.25%。不同年限腐殖酸处理以连续施用5年腐殖酸效果最佳,但连续4年施用腐殖酸和连续5年施用腐殖酸之间差异不显著;考虑实际生产成本投入,推荐选用连续施用4年腐殖酸。研究结果可为长城沿线黄土丘陵旱作农田抗旱保苗提供技术支撑。
英文摘要	Drought seriously limits seedling emergence of crops,resulting in low and unstable crop yield in arid and semi-arid areas in northern China. As a soil amendment,humic acid could resist drought and protect seedlings. Based on a field experiment,we investigated the effects of humic acid applications with duration of 1 to 5 years on foxtail millet emergence rate,dry matter accumulation,root length,antioxidant enzyme activity,and soil moisture at the seeding stage. Results showed that humic acid application increased soil moisture and soil storage water in the 0-60 cm layer at the seedling stage. All the treatments significantly increased emergence rate, above-and below-ground dry matter accumulation,root-shoot ratio,and root length at the seeding, with the increments ranging from 2.62% to 16.53%,3.70% to 111.11%,8.21% to 181.33%,4.22% to 33.25%,and 2.00% to 23.87% respectively. Humic acid application significantly increased SOD,POD and CAT activities. Above-ground biomass and grain yield increments ranged from 4.06% to 20.65% and 0.67% to 16.25%,respectively. The treatment with continuous application of humic acid for five years had the greatest effect,but there was no significant difference between the humic acid treatments continuously applied for four and five years. It is recommended to apply humic acid continuously for 4 years considering the actual production cost. Our results provide technique supports for combating drought and protecting the seedlings in dryland farming in the loess hilly-gully regions along the Great Wall in northern China.
