摘　　要：[目的]探究不同肥料对加勒比松(Pinus caribaea)林下种植大百部(Stemona tuberosa)的生物量及可溶性糖含量的影响。[方法]在百部生长过程中施用稀释50倍和100倍的花生麸液、腐熟羊粪液和发酵猪粪,分别在首次施用后30、60、180、360 d取样进行根数量、鲜重、干重及可溶性糖含量的测定。[结果]各稀释倍数处理的肥料对根数量、鲜重和干重均有促进作用,其中发酵猪粪稀释50倍处理的根数量最多,发酵猪粪稀释50和100倍处理的百部根鲜质量最大,分别为(1 838.5±90.3)g和(1 762.1±90.1)g,分别较清水对照(CK)增加38.24%和32.49%,发酵猪粪稀释50倍和腐熟羊粪稀释50倍处理百部根干质量位居前列,分别较CK增加96.45%和74.86%;可溶性糖含量随着时间的推移先增加后减少,且与肥料浓度呈负相关,发酵猪粪稀释50倍处理含量最低,仅(340.80±17.50) mg/g。[结论]林下种植百部推荐施用发酵猪粪。[Objective]In order to study the effects of different fertilizers on the biomass and soluble sugar content of Stemona tuberosa under Pinus caribaea forest.[Method]Peanut bran,rotten sheep manure and fermented pig manure diluted 50 times and 100 times were applied.The number of roots,fresh weight,dry weight and soluble sugar content were measured at 1,3,6 and 12 months after the first application.[Result]The results showed that the fertilizer under each dilution ratio promoted the number of roots,fresh weight and dry weight of S.tuberosa Lour.Among them,the application of 50 times dilution of fermented pig manure produced the largest number of roots,and the application of 50 and 100 times dilution of fermented pig manure generated the largest root fresh weight,which were(1838.5±90.3)g and(1762.1±90.1)g respectively,38.24%and 32.49%improved from the CK.The dry weight of S.tuberosa root with the treatment of 50 times dilution of fermented pig manure or 50 times dilution of rotten sheep manure was in the top.It was 96.45%and 74.86%higher than CK respectively.The content of soluble sugar was ascending and then descending during the growth.It was negatively correlated with the fertilizer concentration.The content of soluble sugar with the treatment of fermented pig manure diluted 50 times was the lowest(340.80±17.50 mg/g).[Conclusion]It is recommended to use fermented pig manure in the process of planting S.tuberosa under the forest.
