摘要
为了优化蛇皮果高空压条繁殖技术,以挪威产雅苒苗乐N、P、K复合肥为叶面肥料,研究了叶面施肥、不同最大叶长的萌条和造伤方法对蛇皮果高空压条生根的影响。研究结果表明:叶面施肥对蛇皮果高空压条生根具有显著的影响,叶面肥料的最佳质量浓度为3 000 mg/L;不同最大叶长的萌条对压条生根具有显著的影响,其中最大叶长为100～120 cm的萌条生根效果最好;深度造伤与刮茎对压条生根影响无显著差异,两者均适用于蛇皮果高空压条繁殖。
In order to optimize propagation techniques of Salacca zalacca air layering, taking N, P, K compound fertilizer made in Norway as foliage fertilizer, effects of foliage fertilizing, maximum leaf length in layering shoot and injuring method on layering shoot rooting during S. zalacca air layering were studied. The results show that foliage fertilizing and maximum leaf length in layering shoot both have significant effects on layering shoot rooting in S. zalacca, the optimum mass concentration of foliage fertilizer is 3 000 mg/L, and the optimum length of the longest leaf is 100-120 cm. Scraping stem has a similar effect on layering shoot rooting with deeply injuring stem, and both of them are suitable for S. zalacca air layering.
