摘要
为了解福建柏人工林生长与土壤物理性质的关系,为福建柏人工林经营管理提供理论参考,以福建柏-刨花润楠混交林(Ⅰ)、福建柏-桉树混交林(Ⅱ)和福建柏纯林(Ⅲ)为研究对象,对福建柏、林分生长指标和土壤物理性质进行测定。结果表明:人工林Ⅰ福建柏胸径、树高、冠幅及郁闭度最大,Ⅱ总密度最大。Ⅰ土壤最大持水量、田间持水量和孔隙度最大;Ⅲ最小,而土壤密度为Ⅲ最大,Ⅰ最小,土壤体积含水量在3种人工林间变化较大;3种人工林土壤最大持水量、田间持水量和孔隙度随土层加深而降低,土壤密度则增加,土壤体积含水量在不同土层间变化差异较大。据此,提出了营造福建柏-刨花润楠混交林有利于促进林分生长,提高土壤质量;在福建柏人工林经营管理中,要重视土壤物理性质与林分生长的关系。
In order to understand the relationship between the growth of Fokienia hodginsii plantation and soil physical properties and provide theoretical reference for the operation and management of F. hodginsii plantation, the growth index of F. hodginsii and stand and soil physical properties were measured by F. hodginsii-Machiluspauhoi mixed forest(Ⅰ), F. hodginsii-eucalyptus mixed forest(Ⅱ) and F. hodginsii pure forest(Ⅲ) as research objects. The results show that chest diameter, tree height, crown width and depression closure of F. hodginsii of the plantation I are the largest, and the total density of Ⅱ is the largest. The maximum water holding, field water holding capacity and porosity of the soil of I are the largest, and that of Ⅲ is the smallest, while the soil density of Ⅲ is the largest, that of I is the smallest.The soil volume water content varies greatly between the three types of plantations. The maximum water holding, field water holding capacity and porosity of the soil in the three plantations decreased with the deepening of the soil layer.The soil density increased, and the soil volume water content varied greatly between different soil layers. Therefore, the creation of F. hodginsii-M. pauhoi mixed forest is conducive to promoting stand growth and improving soil quality, and in the management of F. hodginsii plantation, it is necessary to pay attention to the relationship between soil physical properties and stand growth.
