摘要: 以薄壳山核桃3年生实生苗为研究对象,选取911、IBA和NAA 3种生根剂,并分别设置50、100、200、300、400 mg/L 5种质量浓度梯度进行浸泡,以不浸泡为对照。探讨苗木移栽成活率、生物量、根系性状等生长指标的变化情况,并利用主成分分析和隶属函数值法对其苗木质量进行综合评价,为薄壳山核桃实生苗移栽后苗木质量研究提供参考。结果表明:不同种类和不同质量浓度生根剂对薄壳山核桃实生苗移栽成活率存在极显著差异,以较低质量浓度的911-50、IBA-50、911-100和IBA-200处理成活率较高,分别达到96.30%、96.30%、92.59%和92.59%,较高质量浓度的911-400、IBA-400、NAA-400处理成活率较低,分别仅为55.56%、77.78%和18.52%;不同处理移栽苗木的地上和地下鲜质量和干质量、新梢鲜质量和干质量、根冠比均不存在显著性差异;不同处理移栽苗木的根长、根表面积、根体积和根直径存在极显著差异,以NAA-200、911-300、NAA-300、911-50、IBA-100处理移栽苗木根系生长效果较好。综合评价结果表明,采用911-300、IBA-50、911-50、911-100、IBA-100、911-200和IBA-300 七个中低浓度生根剂对薄壳山核桃移栽苗木浸根12 h,能显著提高移栽成活率,促进苗木快速生根,培育出优质苗木。

Abstract: With 3‑year‑old seedlings of Carya illinoensis as experimental materials,the growth indexessuch as survival rate,biomass and root traits were investigated under conditions of 50,100,200,300,400 mg/Lof 911,IBA and NAA. Moreover seedlings quality of different treatments was also evaluated by principal component analysis and membership function.The results showed that there was very significant difference in survival rate among treatments with different variety and different concentrations of rooting agents.The survival rates of treatments with lower concentration of rooting agents,911‑50,IBA‑50,911‑100 and IBA‑200 reached 96.30%,96.30%,92.59% and 92.59%.The 911‑400,IBA‑400,NAA‑400 treatments with higher concentration were only 55.56%,77.78% and 18.52%.Fresh quality and dry quality of above ground part,underground part,1‑year‑old branches and root‑crown ratio of transplanted seedlings with different treatments did not show significant difference,but the root length,root surface area,root volume and root diameter showed very significant difference. NAA‑200,911‑300,NAA‑300,911‑50 and IBA‑100 had better effect on root growth. The comprehensive evaluation results showed that when transplanted seedlings were soaked in 911‑300,IBA‑50,911‑50,911‑100,IBA‑100,911‑200 and IBA‑300 treatments with medium and low concentration for 12 h,it could significantly improve the surviv
