不同基质对闽西青冈扦插生根的影响
摘 要:通过开展不同基质对闽西青冈扦插生根时间和生根率的影响研究,结果表明:闽西青冈在不同基质中的平均生根时间和平均生根率差异极显著,且平均生根时间与平均生根率呈极显著负相关;A4处理(3泥碳土∶3珍珠岩∶4红心土)最有利于闽西青冈的扦插生根,平均生根时间和平均生根率分别为30d、%,其他依次是A1处理组(3泥碳土∶3锯末∶4红心土)、A6处理组(3泥碳土∶3蔗渣∶4红心土)。

Abstract:Study on rooting time and rooting rate of Cuttage of Cyclobalanopsis minxiensis by different results show that:The average rooting time and rooting rate of Cuttage were significantly different with different the same time,the average rooting time was negatively correlated with the average rooting rate;Treatment A4 (3 pebspar: 3 perlite: 4 red core soil) was the most favorable for cuttings rooting,the average rooting time and rooting rate were 30 d and %,respectively,and the average rooting time and rooting rate were 30 d and %,respectively,In turn,the treatment group A1 (3 mud carbon soil: 3 sawdust: 4 red core soil) and the treatment group A6(3 clay carbon soil: 3 bagasse: 4 red core soil).

闽西青冈(Cyclobalanopsis minxiensis)为壳斗科青冈属的常绿大乔木,其幼树幼苗耐荫性强,能天然更新,具有速生和硬木质等特性[1],耐贫瘠、耐干旱,是水土流失综合治理的重要树种之一。闽西青冈不但是良好的用材树种,还是良好的园林观赏树种,可用于四旁绿化和景观改造等[2-5]。笔者对闽西青冈在不同基质中扦插生根进行了研究,旨在为闽西青冈的扦插繁殖和保护提供理论依据。
1 材料与方法
材料来源 2017年5月中旬,在福建农林大学南平校区后山采穗,选择半木质化、叶芽饱满的穗条,将采下的穗条装入水桶和盖上湿报纸,将穗条保湿和避免组织损伤,
