Abstract: In order to explore the cultivation potential of Dendrocalamopsis oldhamii in Nanchong, the barreled seedlings of Dendrocalamopsis oldhamii were used to carry out summer and winter cultivation experiments in three districts and counties of Nanchong. The number of shoots, the diameter of the grown bamboo, the morphological characters of the height of the plant, and the cold tolerance were compared. The results showed that the survival rate of D. was above 82%. After planting in summer, bamboo shoots could be produced in the same year, with an average of 3.4 to 5 shoots. When bamboo shoots developed into a first generation of bamboo in winter, the average ground diameter was 1.76~2.49cm, the average plant height was 2.4-3.1m. In the second year, the second-generation induced from the first-generation bamboo shoots was on average 2 shoots, and the average ground diameter of the second-generation was 1.5 times that of the first generation, and the average plant height is 1.56-1.85 times that of the first generation. After planting in winter, 5.1-5.8 bamboo shoots could be produced in the next summer and autumn, and the average diameter of the developed adult bamboo was 2.11-3 cm, and the average plant height was 2.65-3.86 m. There was no obvious freezing injury of D. in winter. It is considered that D. is suitable for introduction and cultivation in Nanchong, and the relevant research has increased the suitable range of D. in Chongqing to the north by 2 to 3 latitudes.
