摘要
通过对美国红栌引种、培育繁殖、造林等试验研究,结果表明:美国红栌适应性强,生长迅速,在黏性重、土层紧实、排水不良地块,成活率仅23%;在砂性重、不积水地块,成活率92%;在南方影响红栌生长的主要因素是雨水,过多雨水会造成烂根。在干旱条件下,施用保水剂能明显提高其造林成活率和生长量;嫁接速度对美国红栌嫁接成活率有显著影响。
Through experiments of the introduction, cultivation, afforestation on Continvs coggygria, the results show that the adaptability of Continvs coggygria are stronger and the growth of it are rapid. On the plots with heavier tenacious clay and burly soil layer, the survival ratio is only 23% and all on heavier viscous and non water-storing plots , the survival ratio is 92%. The rainwater are the main factors influcing the growth of Continvs coggygria. Lot of rainwater can cause root rot. Super absorbent polymer application can increase the survival ratio and growth under drought. Grafting speed has significant influence on grafting survival ratio.
