栓皮栎具有幼苗期间地上部分生长缓慢、地下部分主根生长迅速而侧须根少的特点。为了提高植苗造林成活率,需要控制主根长度,促进侧须根生长。控根方法不同,促其侧须根生长的效果不同,对苗木质量和育苗成本会有影响,本研究对栓皮栎的几种控根方法进行对比试验,探讨有利于栓皮栎侧根和须根生长的措施,试图揭示最有利于培育栓皮栎优质苗木的方法。
Quercus variabilis has the characteristics of slow growth of aerial parts during seedling growth, rapid growth of main root roots in the underground part and few lateral roots. In order to improve the survival rate of plantation and afforestation, it is necessary to control the length of main root and promote the growth of lateral fibrous roots. Different root control methods promote the growth of lateral fibrous roots and have different effects on nursery stock quality and nursery costs. In this study, several control methods of Quercus variabilis were compared to explore the measures that are conducive to the growth of lateral and fibrous roots of Quercus variabilis , Trying to reveal the most conducive to nurturing high quality seedlings of Quercus variabilis.
