摘要
为提高阔叶树种造林成活率,对栓皮栎、榆树、辽东栎等树种开展了不同穴盘规格、育苗基质、育苗方式试验,采用方差分析、多重比较(duncan)等对试验数据进行分析。结果表明:(1)28孔穴盘苗木生长及根系发育情况最优,32孔次之,50孔最差,且28孔与32孔之间差异不显著,考虑育苗成本,建议采用32孔穴盘育苗;(2)最适的穴盘育苗基质配比为草炭土∶珍珠岩∶蛭石=2∶1∶1(体积比);(3)3种育苗方法,在侧根量和须根量方面,穴盘苗>容器苗>裸根苗,因此,选用穴盘培育的种苗,可以提高造林成活率。
In order to improve the survival rate of broad-leaved trees in afforestation,the experiments on different hole plate specifications,seedling substrate and seedling method of Quercus variabilis,Ulmus pumila and Quercus Liaotungensis,etc.was carried out.The data were analyzed by variance analysis and multiple comparison(duncan).The results showed as the following three aspects.(1)The growth and root development of 28-hole tray seedling was the best,followed by 32-hole tray,and the 50-hole tray was the worst,and there was no significant difference between 28-hole tray and 32-hole tray.Considering the cost of seedling cultivation,32-hole tray is recommended to be used for seedling cultivation.(2)The optimal substrate ratio of pothole seedling rearing was peat soil∶perlite∶vermiculite=2∶1∶1(volume ratio).(3)Three seedling rearing methods were adopted,in terms of lateral root quantity and root quantity,pothole seedling>container seedling>bare root seedling.Therefore,the selection of pothole seedling breeding can improve the survival rate of afforestation.
