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.
