Study on Container Seedling Raising Techniques of Ormosia hosiei in Southern Sichuan

In order to establish a container seedling raising technical system for Ormosia hosiei in southern Sichuan, the effects of substrate ratio, container specification and of slow-release fertilizer amount on the growth of Ormosia hosiei were analyzed by the factorial experiment design. The results showed that the growth of container seedlings of 1-year-old Ormosia hosiei tree was affected by three factors, including substrate ratio, container specification and slow-release fertilizer amount, and their pairwise interaction. The highest quality seedlings could be obtained in medium-sized containers and low amount of slow-release fertilizer by using A2 substrate （coconut bran 2∶peat 2∶soil 1） and A3 substrate （coconut bran 1∶peat 1∶soil 2）, which could save the cost of container seedling. The most suitable combination of factors for container seedling raising of Ormosia hosiei in southern Sichuan was as follows: the substrate ratio was coconut bran 2∶peat 2∶soil 1, the amount of slow-release fertilizer was 1 kg/m³, the container specification of non-woven container was 10 cm ×13.5 cm.
