摘　　要：目的:比较有机栽培条件下宁夏枸杞不同品种生长特性及抗性差异,为筛选适合有机生产的枸杞品种提供参考。方法:以宁夏枸杞6个品种(“宁杞1号”“宁杞4号”“宁杞5号”“宁杞7号”“杞鑫10号”和枸杞品系“0909”)为实验材料,按中国有机标准种植于同一地块并统一管理,分别调查枸杞物候期、生长量、果实性状、产量、枸杞群落5种主要害虫种群数量、黄叶率,测定枸杞多糖和甜菜碱含量并进行综合比较分析。结果:6个参试品种中,“宁杞7号”植株长势较好,产量和品质较高;“宁杞4号”“宁杞1号”产量次之,但抗性较强;“宁杞5号”长势旺,瘿螨问题较严重,果粒较大但整体产量较低;“杞鑫10号”长势较好,果粒较大但对修剪管理技术要求较高,本试验期间未高产;枸杞品系“0909”长势较弱,产量较低,抗性较差。结论:推荐将“宁杞7号”“宁杞4号”和“宁杞1号”作为宁夏枸杞产区有机种植优选品种。Objective:To explore the difference in growth characteristics and resistance among different cultivars of Lycium barbarum under organic cultivation conditions,so as to guide the screening of cultivars suitable for organic production.Methods:The six cultivars of L.barbarum("Ningqi 1","Ningqi 4","Ningqi 5","Ningqi 7","Qixin 10",and"0909")were cultivated in the same plot according to relevant organic standards in China and managed with the same method.The phenological period,growth,fruit traits,yield,populations of five main pests in L.barbarum community,and percentage of yellow leaves were investigated,and the content of polysaccharides and betaine was determined and compared.Results:Among the six cultivars,"Ningqi 7"showed ideal growth vigor and high fruit yield and quality.The fruit yield of"Ningqi 4"and"Ningqi 1"came in the second,but the two demonstrated strong resistance."Ningqi 5"displayed strong growth vigor,large fruits,and low yield with severe invasion of Aceria pallida."Qixin 10"had vigorous growth with large fruits,but it requires high pruning management,so the yield was not high during the experiment period.The cultivar"0909"showed weak growth vigor,low yield,and poor resistance.Conclusion:"Ningqi 7","Ningqi 4",and"Ningqi 1"were recommended as the preferred cultivars for organic cultivation in Ningxia.
