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.
Abstract
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 in-vestigate the effects of these substrate on the growth of Phoebe chekiangensis and Phoebe bournei container seed-lings,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 chek-iangensis seedlings,while Recipe 7(peat∶bark∶husk∶perlite∶river sand=1∶4∶2.5∶0.5∶2)was more fa-vorable 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 spe-cies.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 sus-tainable seedling cultivation solution for forestry production.
