摘要
研究采用泥炭、树皮、谷壳、珍珠岩、黄心土、河沙、田土等原料,按照不同体积比例配制了11种基质配方,探讨了这些配方对浙江楠和闽楠容器苗生长的影响,旨在筛选出这2种珍贵树种的最佳育苗基质。结果表明:配方3(泥炭∶树皮∶谷壳∶珍珠岩=2.5∶4∶2∶1.5)最适宜浙江楠容器苗的培育,而配方7(泥炭∶树皮∶谷壳∶珍珠岩∶河沙=1∶4∶2.5∶0.5∶2)则更适合闽楠容器苗的生长。这一差异可能源于2种树种在生物学特性、生长习性以及对环境条件的适应性上的不同。适宜浙江楠生长的基质依赖泥炭基质,因其提供优质养分和良好物理环境,而对闽楠而言,使用树皮和谷壳等替代材料,也获得良好育苗效果,且成本更低,为林业生产提供经济可持续的育苗方案。
In this study,11 different substrate recipes were prepared by various materials such as peat,bark,husk,perlite,yellow subsoil,river sand,and farmland soil based on different volumetric ratios.The objective was to investigate the effects of these substrate on the growth of Phoebe chekiangensis and Phoebe bournei container seedlings,aiming to identify the optimal seedling substrates for these two precious tree species.The results indicated that Recipe 3(peat∶bark∶husk∶perlite=2.5∶4∶2∶1.5)was most suitable for the cultivation of Phoebe chekiangensis seedlings,while Recipe 7(peat∶bark∶husk∶perlite∶river sand=1∶4∶2.5∶0.5∶2)was more favorable for the growth of Phoebe bournei container seedlings.This variation might be attributed to differences in biological characteristics,growth habits,and adaptability to environmental conditions between the two tree species.The ideal substrate for Phoebe chekiangensis relied on peat due to its ability to provide high-quality nutrients and a favorable physical environment.In contrast,for Phoebe bournei,the utilization of alternative materials such as bark and husk achieved satisfactory seedling cultivation results with lower costs,offering an economically sustainable seedling cultivation solution for forestry production.
