Comparative Analysis of Growth of Container Seedlings of Cunninghamia lanceolata Under Seedling Cultivation Conditions
To study the growth status of container seedlings of Cunninghamia lanceolata under different seedling cultivation methods,in 2023,three seedling cultivation methods,namely sand bed,hole tray,and sand bed+hole tray,to cultivate container seedlings of Cunninghamia lanceolata were used as the research object.Measurement and analysis of growth rate,growth range,and biomass was conducted.The results indicate that:The growth and biomass of container seedlings cultivated on sand beds showed better performance.The average height,diameter,and total biomass of container seedlings cultivated under three different seedling cultivation methods were 10.7％,2.6％,and 13.0％higher,respectively;There was a significant difference in the distribution frequency of container seedlings of Cunninghamia lanceolata cultivated under three different seedling cultivation methods between 20～30 cm and 30～40 cm in height(P＜0.05).The distribution frequency difference of seedling height between 10～20 cm was not significant(P＞0.05),and the distribution frequency difference of ground diameter in each interval was not significant(P＞0.05).
