4种槭树苗木生长特性及其培育措施

Research on Seed Properties and Cultivation Measures of Four Species of Acer

白牛槭（Acer manshruricum）、紫花槭（A．pseudo‐sieboldianum）、色木槭（A．momo）和茶条槭（A．ginala）实生苗培育试验表明：4种槭树种子育苗在东北地区易行；1年生幼苗中白牛槭长势相对较弱，从第2年至第5年紫花槭转为弱势生长，4种苗木生长势强弱依次为色木槭＞茶条槭＞白牛槭＞紫花槭。茶条槭和白牛槭苗木无需人工修剪，2～3年龄苗即可直接应用；色木槭生长速度快但冠型发育较晚，辅以人工修剪整形，4年龄苗可出圃应用；紫花槭具有风干稍现象，严重影响其生长和冠型发育，在东北地区可考虑灌木型紫花槭苗木的培育和园林应用。

Acer mandshuricum Maxim .,Acer pseudo‐sieboldianum ,Acer mono Maxim .and Acer ginnala seedling cultivation test showed that ：four species of Acer seed‐seedlings to be easy in the northeast ,one year seedling all strong growth except for Acer mandshuricum Maxim ., Acer pseudo‐sieboldianum reversion to weak grow th from second to fifth years ,the order of seedling growth potential strength were ：Acer mono Maxim .〉 Acer ginnala 〉 Acer mandshuricum Maxim .〉 Acer pseudo sieboldianum .Acer ginnala and Acer mandshuricum Maxim .seedlings without artificial pruning ,the seedlings which would natural growth about two and three ages can be plantation ;High growth speed but crown type growth later of Acer mono Maxim .,sup‐plemented by artificial pruning , four ages seedlings provide an effective for application ;A cer pseudo‐sieboldianum due to dry slightly phenomenon seriously affect the grow th and development of tree crow n ,application of shrub seedlings cultivation can be considered in the mandshuricum landscape .
