5种壳斗科树种1年生幼苗生长比较
|
摘要
笔者以1年生橿子栎(Quercus baronii)、栓皮栎(Quercus variabilis Bl.)、辽东栎(Quercus liaotungensis)、槲栎(Quercus aliena Bl.)和欧洲山毛榉(Fagus sylvatica)营养钵幼苗作为试验材料,分析对比其各项生长指标以及地上部分、地下部分生物量和根系生长情况。结果表明,在山西省南部地区,相同的生长环境及育苗措施下,5种壳斗科树种的幼苗在部分生长指标上表现出差异性。其中,山毛榉1年生幼苗苗高、侧根重、1级侧根长、2级侧根数、2级侧根长表现最好;槲栎地径指标表现最好;栓皮栎地下生物量、主根重、根冠比指标表现最好;而辽东栎、橿子栎各项生长指标表现均一般。
1-year-old Quercus baronii, Quercus variabilis Bl., Quercus liaotungensis, Quercus aliena Bl. and Fagus sylvatica nutrition container seedlings were used as experimental materials. Their growth indicators, aboveground biomass, underground biomass and root growth were analyzed and compared. The results showed that 5 species of broad-leaved tree seedlings showed differences in partial growth indicators under the same growth environment and nursery measures in the southern part of Shanxi province. 1-year-old seedling height, lateral root weight, level 1 lateral root length, level 2 lateral roots and level 2 lateral root lengths of Fagus sylvatica were the best. Ground diameter index of Quercus aliena Bl. was the best. Underground biomass, main root weight and root-shoot ratio indicators of Quercus variabilis Bl. were the best. While the growth indicators of Quercus liaotungensis and Quercus baronii were all in general.
