摘要
[目的]研究促进白刺(Nitraria tangutorum)硬枝扦插生根成苗的最佳生长调节剂种类、浓度及其组合.[方法]以白刺2～3 年生直径＞0.4 cm的木质化枝条为插穗材料,进行不同生长调节剂、不同浓度处理的扦插对比试验.[结果]不同处理下白刺扦插苗的成活率、苗高、总根数、最长根长差异显著;其中NAA 400 mg/L处理下白刺的成活率最高,达57.69%,复硝酚钠400 mg/L处理下白刺的苗高最高,为38.00 cm;IBA+NAA 200 mg/L处理下白刺的总根数最多,为15.00条;NAA-Na 600 mg/L处理最长根长最长,为35.00 cm.[结论]经隶属函数法综合评价,IBA-K+NAA-Na 600mg/L处理的隶属函数值最高,是适合白刺扦插的最佳处理.
Abstract
[Objective]In order to find out the best kind,concentration and combination of growth regulators for promoting rooting of hardwood cutting of Nitraria tangutorum.[Method]In this study,the different growth regulators and concentrations of different treatments were used to control the cutting of woody twigs of Nitraria tangutorum with diameter＞0.4 cm from 2 to 3 years old.[Result]The results showed that there were significant differences under different treatments in survival rate,seedling height,total number of roots,longest root length;and the sur-vival rate of treatment NAA 400 mg/L was the highest,up to 57.69%.The seedling height of treatment Sodium Nitrophenolate 400 mg/L was the highest,up to 38.00 cm.The total number of roots of treatment IBA+NAA 200 mg/L was the highest,up to 15.00 articles.The longest root length of treatment NAA-Na 600 mg/L was the highest,up to 35.00 cm.[Conclusion]After comprehensive evaluation by the membership function method,the membership function value of IBA-K+NAA-Na 600 mg/L treatment is the highest,which was the best treatment for the hard wood cutting of Nitraria tangutorum.
