The forest seeds is an important material basis for efficient cultivation of forest resources,to optimize the allocation of Cunninghamia lanceolata seed-application resources,take Fujian province Cunninghamia lanceolata center production area Jianou and the Datian County two place seedling source seed as the comparison,produced the State-owned forest of Youxi,in Fujian province 10 units 14 a1-3 varieties of Cunninghamialanceolataseed Orchard light substrate container experiment.Through on height,and stems,and high stems than,and quality index,8 a seedling growth and quality index of survey determination analysis,results showed that:Cunninghamia lanceolata different generation seed and same generation different seed Orchard seed between of growth index are exists very significantly or significantly differences,Cunninghamia lanceolata different seed of seedlings growth characteristics exists differences;according to height,and diameter and biomass for seedlings quality integrated evaluation results showed:different generation seed of seedlings quality General Shang is better than control group,seedlings quality index highest of is Youxi forest 3 generation,Total population average 25.21% percent higher,followed by Yangkou forest 3 generations,Guangzehuaqiao forest3-generations,Guanzhuang forest 2.5-generation,Changting 2-generation,higher average total population 14.12%.
