福建小湖赤枝栲苗期生物产量的研究

Study on the Biomass Production of Castanopsis kawakamii Seedling in Xiaohu Region of Fujian

研究了四种不向的育苗方式对赤枝栲苗期生物产量的影响,结果表明;赤枝栲一年生苗木的生物产量比二年生的低,在生物量的分配上,一年生的根(42.93％～56.48％)>叶(33.27％～44.64％)>茎(9.32％～13.98％);二年生的根(34.02％～40.34％)>叶(27.71％～37.64％)≈茎(27.26％～38.27％);在不同育苗方式的影响下,生物产量发生很大的变化,用根蘸药物最佳,苗床垫底,切胚根次之,以营养袋为最差;赤枝栲苗木生物产量,在各器官之间存在着密切的相关性。

This paper deait with the effects of various methods of growing seedling on the biomass production of Castanopsis kawakamii seedlings. The results showed that(1): biomass production of the first year seedling is lower than that of the second yean (2) the distribution of biomass:the first year seedling, root (42. 93%-56. 48%)>leaf (33. 27%-44. 64%)>stem(9. 32%-13. 98%);the second years seedling:root (34. 02%-40. 34% )> leaf (27. 71%-37. 64%)≈stem(27. 26%-38. 27%);(3)the effects of various methods .med-icai treatment>cutting radical treatment, treatment of padding with plastic cloth>treatment with nutrient bag. (4) various organs biomass of the seeding were closely correlated.
