桉树育苗容器与基质研究

桉树种苗年需求量在15亿株以上,如何改善苗木质量、提高苗木抗性、降低成本等是亟待解决的问题。目前桉树种苗培育方式主要是采用塑料薄膜容器装填黄心土,少量苗圃采用穴盘、纸杯和装填轻型基质培育方式。轻型基质网袋配合特制穴盘育苗方式所培育的苗木具有根系平衡且发达,苗木抗逆性强;种植时不用脱掉容器,根系穿透网袋,水平自然生长,提高造林成活率;造林后无缓苗期,初期生长量显著提高;重量轻,包装运输方便等优点,其技术和产品发展较快。

Research on Container and Growing Media of Cultivation Eucalyptus Seedlings

Eucalyptus afforestation need about 1.5 billion seedlings per year in China. It is a big problem how to improve seedling quality and reduce cultivating cost. Now, the primary method is to use plastic film plot and soil filler for eucalyptus seedling cultivation. Plastic tray and paper-pot are used in a few nurseries. A new cultivation technology to use no-spin-sacking container and special plastic tray is expanding rapidly. The seedlings cultivated by new technology have more roots, stronger resistances against poor growing conditions,and are used easily to plant with container and the seedling roots can penetrate through sacking to grow naturally. Therefore this seedling breeding by container and media would improve survive ratio,growth of the stand in initial stages. The other advantages include the seedlings are more light,and helpful to pack and transport.
