A Study of Container Seedling-raising Tests of Pterocarpus marsupium
-
摘要: 以培育6月苗龄囊状紫檀容器苗为对象,采用正交试验设计方法开展容器规格、肥料种类和育苗基质对苗木各指标生长的影响研究。结果表明,随着育苗容器规格的增大,苗木的各项指标的生长量明显增多。施5%有机肥的苗高和地下部分的干重明显优于施2%磷肥和1%复合肥,但三者间的地径、主根长、地上部分干重及全株生物量差异不显著。采用80%森林土+20%火烧土的育苗基质培育的容器苗生长表现最好。对不同因素、不同水平的各个组合处理进行分析,6月生囊状紫檀的容器育苗最佳组合为12 cm×16 cm (或9 cm×12 cm)的容器规格,施用2%的磷肥作为基肥,采用80%森林土+20%的火烧土作为育苗基质。Abstract: Taking six-month containerized seedlings of Pterocarpus marsupium as the research object,studies were made of the influence of container size,fertilizer type,nursery substrate on the growth of seedlings by using the orthogonal experiment design method. The results showed that the growth indexes of seedlings obviously increased with the increasing of container size. The height and undergrounddry weight of seedlings by applying 5% organic fertilizer were significantly higher than that by applying 2% phosphorus and 1% compound fertilizer,but there were no obvious differences among three samples in the ground diameter,main root length, aboveground dry weight and whole-plant biomass. The containerized seedlings grew best by using substrate of 80% forest soil + 20% fire soil. By analyzing the difference factors and levels of each combination,the best combination for six-month seedlings of Pterocarpus marsupium was to use 12 cm×16 cm (or 9 cm×12 cm) container size,2% phosphorus and substrate of 80% forest soilt + 20% fire soil.
