Breeding Techniques of Taiwania flousiana Plantation in Changning

This study was conducted on Taiwania flousiana seeding which were cultivated in 2 types of seedlings in Changning. Through 6 different planting methods, 4 kinds of clearing land preparation methods and 3 kinds of management measures, the growth of 20 years old T.flousiana was observed and analyzed. The results showed that there were significant differences on survival rate between 2 types of seedlings after planning (P < 0.05). The survival rate of container seedling with different planting methods reached an average of 90.82%, which was significantly higher than that of bare root seedling afforestation (P < 0.05). There was no significant difference between planting patterns. Soil B layer excavation planted pond backfill soil contact seedlings root and seedling root wall direct contact with colonization was significantly higher than other planting methods The afforestation effect of T.flousiana was influenced by the management measures. 5 a After planting, the forest than tending more than once a year was benefit to the afforestation. The slope aspect and position was the important terrain factors for the growth of T.flousiana. A ridge block was unsuitable for the propagation of T.flousiana.
