摘要
对‘红妃’鸡爪槭(Acer palmatum‘Hongfei’)的快繁与容器栽培技术进行总结,并分析了其在江苏句容、溧阳和吴江3个试验点的区域试验结果,3个试验点均以‘出猩猩’鸡爪槭(Acer palmatum‘Deshojoi’)为对照品种。快繁技术包括采穗圃营建、砧木苗培育、嫁接苗培育和嫁接后管理,应选择土壤深厚、排水良好的圃地作为‘红妃’鸡爪槭的采穗圃,选用生长健壮且无病虫害的2~3年生优良无性系作为采穗圃的母株,在秋季采用嵌芽接法嫁接成活率较高,科学进行嫁接后的管理。容器栽培技术包括容器选择、基质选择、水肥管理、整形修剪,容器以苗木根系在其中自然展开为宜,基质以泥炭和蛭石的混合物为宜,施用1∶200浓度的氮、磷、钾混合肥料水溶液或苗木栽培的专用肥料,适时进行整形修剪。该植物在江苏句容、溧阳和吴江3个试验点的物候期均早于‘出猩猩’鸡爪槭,叶色稳定,生长良好。本文为‘红妃’鸡爪槭在华东地区的园林绿地推广应用提供参考。
The rapid propagation and container cultivation technology of Acer palmatum‘Hongfei’were summarized,and the regional trial results of it at 3 test sites in Jurong,Liyang and Wujiang,Jiangsu Province were analyzed.At all 3 test sites,Acer palmatum‘Deshojoi’was used as the control variety.The rapid propagation techniques include the construction of the spike nursery,the cultivation of rootstock seedlings,the cultivation of grafted seedlings and the management after grafting.A nursery with deep soil and good drainage should be selected as the spike nursery for Acer palmatum‘Hongfei’.Healthy and disease-free excellent clones of 2 to 3 years old should be selected as the mother plants of the spike nursery.The survival rate of grafting by bud entraption in autumn is relatively high.Manage the grafted area scientifically.Container cultivation techniques include container selection,substrate selection,water and fertilizer management,and shaping and pruning.The container should be such that the root system of the seedlings naturally spreads in it.The substrate should be a mixture of peat and vermiculite.Apply a 1∶200 concentration nitrogen,phosphorus and potassium mixed fertilizer solution or special fertilizer for seedling cultivation.Shaping and pruning should be carried out in a timely manner.The phenological period of this plant in the 3 experimental sites of Jurong,Liyang and Wujiang,Jiangsu Province,was earlier than that of the Acer palmatum‘Deshojoi’.It had stable leaf color,good growth.This article provides a reference for the promotion and application of Acer palmatum‘Hongfei’in garden green spaces in East China.
