摘　　要：以3个国外引进工业大麻品种格列西亚(V_(1))、金刀15(V_(2))和格里昂(V3)为试验品种,研究在轻、中度盐碱条件下工业大麻的生长特性、叶面积、干物质重以及原茎产量。结果表明,不同品种的株高、茎粗、根长、根体积、叶面积及干物质重随着土壤盐碱浓度的提高呈降低的变化趋势,轻度盐碱土高于中度盐碱土,差异显著;在盐碱土胁迫条件下,V_(1)的生长发育特性优于V_(2)和V3,中度盐碱胁迫V_(1)的原茎产量最高,V_(2)比V_(1)和V3分别减少4.34、0.74 t/hm^(2),差异显著;结论:V_(1)的抗盐碱性最强,V_(2)最差。Three imported industrial hemp varieties ofГлесия(V_(1)),Золотоношские15(V_(2))andГляна(V_(3))were used as experiment,the growth characteristics,leaf area,dry matter weight and stem yield of industrial hemp under light and moderate saline-alkali conditions were studied.The results showed that plant height,stem diameter,root length,root volume,leaf area and dry matter weight of different varieties decreased with the increase of soil salinity and alkali concentration,light saline-alkali soil was higher than moderate saline-alkali soil,and the difference was significant.Under saline-alkali soil stress,the growth and development characteristics of V_(1) were better than those of V_(2) and V_(3).The stem yield of V_(1) under moderate saline-alkali stress was the highest,and V_(2) decreased by 4.34,0.74 t/ha,respectively.Compared with that of V_(2) and V_(3),the difference was significant.The conclusion is that V_(1) has the strongest salt and alkali resistance and V_(2) has the worst.
