马尾松和湿加松轻基质网袋容器育苗试验

以传统基质（黄心土50％＋森林表土50％）为对照，对马尾松和湿加松轻基质网袋容器育苗进行试验的结果表明：松皮粉100％（A）、松皮粉70％＋锯末20％＋森林表土8％＋杉皮粉2％（B）配方的容器苗高和地径均显著高于对照，容器基质重量最轻；松皮粉50％＋锯末4JD％＋森林表土8％＋杉皮粉2％（C）配方次之，但其单株干物质的总重量最大；松皮粉30％＋锯末60％＋森林表土8％＋杉皮粉2％（D）配方生长表现最差。建议生产上培育马尾松和湿加松轻基质网袋苗时，添加约70％的松皮粉、20％的锯末作为育苗基质。

Research of Pinus massoniana and P. elliottii×P. oaribeea seedlings with Light Growing Media and Degradable Container

A trial was carried out on media selection for raising Pinus massoniana and P. eUiottii × P. oaribeea seedlings with light growing media and degradable containers. The result showed that seedling height and diameter in media A （100% of pine skin） and B （70% of pine bark, 20% saw powder, 8% top-soil under pine forest, 2% Chinese fir bark, v/v） were remarkably higher with lower weight of container than the control, seedlings grew also well inmedia C （50% of pine bark, 40% saw powder, 8% topsoil under pine forest, 2% Chinese fir bark, v/v） with the highest biomass per plant, while seedlings grew poorest in media D （30% of pine bark, 60% saw powder, 8% top - soil under pine forest, 2% Chinese fir bark, v/v）. It was recommended that the media containing 70% of pine bark and 20% saw powder be used to grow container seedlings of P. massoniana and P. eUiottii × P. oaribeea.
