黄山栾树切根育苗试验研究

Test of Growing Seedlings for Koelreuteria bipinnata by Cutting Roots

通过黄山栾树切根和沾灰处理育苗试验,结果表明,切根在一定程度上降低了发芽率,但同时能使黄山栾树苗木主根变短,侧根发根部位提高,侧根变粗,使得根系发达,苗木地径和苗高明显增加,生长旺盛,从而有利于苗木质量的提高;沾灰处理可以在一定程度上提高了成活率。研究结果可以为黄山栾树园林苗木培育提供参考。

Test on growing seedlings for Koelreuteria bipinnata Fr.Var.integriforioota by cutting roots and staining with ash was carried out.The results showed that cutting roots decreased the germination percent？age in a certain extent,and could shorten main root of nursery stock,raise the position of roots on the side,largen fibrous root and make root system be developed so that nursery stocks had vigorous growth in form that diameter and height increased significantly,and that cutting roots were useful for improving the quality of nursery stock;Staining with ash improve the seeding rate in a certain extent.The conclusion can provide reference for cultivating garden nursery stock of K.bipinnata.
