【摘要】 为了研究不同改良措施对盐碱地枸杞生长发育的影响，以宁杞1号为试验材料，采用拉丁方设计，设置5个改良措施，分别为脱硫石膏、改良剂+有机肥、排灌、脱硫石膏+排灌、脱硫石膏+有机肥+改良剂+排灌措施，以不采用任何改良措施为对照，分析不同改良措施下枸杞生长的生理指标、果实有效成分质量分数及产量等的变化，并对2年的测定结果进行主成分分析。结果表明：各项改良技术均降低了土壤的pH和碱化度，并增加了枸杞黄酮质量分数；施用有机肥的2个处理对果实产量的促进效果较大，施用脱硫石膏和排灌措施可促进枸杞果实中多糖的积累。主成分分析结果显示，与对照相比，脱硫石膏+有机肥+改良剂+排灌措施处理下，枸杞叶片的净光合速率增加23.3%，果实产量、果实黄酮质量分数分别增加32.57%、41.5%。因此，施用脱硫石膏和有机肥及改良剂等技术综合模式可以显著促进盐碱枸杞的生长发育及其有效成分的积累。更多还原

【Abstract】 To investigate the effects of various improvement measures on the growth and development of Lycium barbarum in saline-alkali soil, with L. barbarum ‘Ningqi No.1’ was used as the test material. A Latin square design was employed to evaluate five improvement measures: desulfurized gypsum, amendment+organic fertilizer, drainage and irrigation, desulfurized gypsum+drainage and irrigation, and desulfurized gypsum+organic fertilizer+amendment+drainage and irrigation, with no improvement measures as the control. The changes in physiological indices, active component content, and yield of L. barbarum under different improvement measures were analyzed, and principal component analysis on the two-year measurement results was conducted. The results showed that all improvement techniques reduced soil pH value and alkalinity, and increased the flavonoid content in L. barbarum. The two treatments involving organic fertilizer significantly enhanced fruit yield. Desulfurized gypsum combined with drainage and irrigation promoted polysaccharide accumulation in the fruits. Principal component analysis showed that, compared to the control group, the treatment with desulfurized gypsum+organic fertilizer+amendment+drainage and irrigation increased photosynthetic performance by 23.3%, fruit yield by 32.57%, and fruit flavonoid content by 41.5%. Therefore, the integrated use of desulfurized gypsum, organic fertilizer, and amendments can significantly promote the growth, development, and accumulation of effective components in L. barbarum grown in saline-alkali soil.更多还原
