半干旱地区野生平榛人工恢复试验初报

摘要

In Xingjiu Village of Gannan County , according to ecological habits of Corylus heterophylla, artificial cultivation experiments were conducted by using four measures :water retaining agent +rooting powder, water retaining agent, rooting powder, natural planting (CK). Result shows that: different measures have significant differences;among which water retai- ning agent +rooting powder which have the highest survival rate, being 81%, and are significantly higher than that of CK; to some extent different measures promote the growth of wild Corylus heterophylla; artificial wild Corylus heterophylla sapling sensitively reflect to extreme drought or cold weather, and their deadwood occur.%在甘南县兴久村，根据平榛的生态习性采用施用保水剂＋生根粉、保水剂、生根粉、自然栽植（对照）等4种不同处理措施进行了人工栽培试验。结果表明：不同处理措施之间成活率存在较大差异，其中保水剂＋生根粉处理成活率最高，可使当年栽植的野生平榛成活率达81％，明显高于对照的58％；同时不同处理措施在一定程度上促进了野生平榛的生长；另外野生平榛人工栽植幼林对极端干旱或低温天气反应敏感，有枯枝情况出现。
