Chino. 利用农业生产废弃资源，对泥炭、木屑、农家肥（牛粪＋山核桃壳）、树皮4种不同基质材料的物理性质、水分特性及对园林植物红叶石楠容器苗生长影响进行研究。研究结果表明：通过性能指标比较和主成分分析，农家肥（牛粪＋山核桃壳）、珍珠岩、蛭石（三者基质比为60：20：20）等轻基质资源作为容器育苗的基质原料使用，具备国内外通用育苗基质原料的相似理化基础，是较理想的容器育苗复合基质的原材料。另外，木屑和泥炭也是较好的复合基质原料，基质肥力持久性能好；树皮须与其它原材料按合适的配比混合使用，改善复合基质的性能，能降低生产成本。[著者文摘]

With the fast development of greening seeding enterprises and their industrialized management, medium materials are widely used in seeding culture under the condition of limited farmland resources. The demand for medium materials increases greatly. It is necessary to find medium materials which are rich in local resources and cheap. Using the abandoned resources of agricultural production, the study was conducted to investigate the physical and water chanaters of four materials, namely, peat, wood pellet, cattle excrement with walnut shell and bark and their influences on the growth of the container seedlings of the garden plant Photinia frasery. The results showed that the best media were consisted of cattle excrement with walnut shell ,perlite and vermiculite, which have the same physical characters of the universal media at home and abroad, the ratio was 60： 20：20 respectively. However,wood pellets media and peat media were also good for container seedlings. Bark must be used with other materials at a suitable ratio, so as to improve the characters of the mixed media and reduce the cost.
