摘要
以科尔沁沙地栽培的辽榛3号(84-226)、辽榛7号(82-11)和达维(84-254)3个平欧杂种榛(Corylus heterophylla Fish.×Corylus avellana L.)为试验材料,研究不同材质、不同粗度的缢根材料对平欧杂种榛压条苗生根率、生根数量、生根基径、生根长度以及地上部分的影响。结果显示:科尔沁沙地栽培的平欧杂种榛在繁育苗木时,采用22号铁丝(?=0.711mm)作为缢根材料,效果最佳,成本最低。
Taking Corylus heterophylla Fisch.×Corylus avellana L.‘Liaozhen 3＇（84-226）,Corylus heterophylla×Corylus avellan ‘Liaozhen 7＇（82-11）,and Corylus heterophylla ×Corylus avellan ‘Dawei＇（84-254）as research objects,effects of different root-tied materials with different material thicknesses on rooting rate,rooting number,rooting diameter,rooting length aboveground part were studied.Result shows that taking No.22 iron wire（φ=0.711mmφ）as the root-tied material can obtain the optimal effect and its cost is the lowest.
