| 摘 要： | 目的]对地果植株的叶部性状与主要土壤生态因子进行相关性分析。方法]在对野生地果进行野外调查的基础上，研究了土壤生态因子（水分、N、P、K、有机C）对地果叶部性状的影响。结果]土壤含水量对地果单叶面积、叶片数量有显著影响。随着土壤含水量上升，地果叶片变长、变宽，单叶面积增加而叶片数减少，茎节长度增加。土壤N和有机C含量对地果叶部性状的影响不显著，其中土壤N含量与叶片数量呈不显著负相关，与茎节长度呈不显著的正相关，表明地果具有耐贫瘠的特点。地果对土壤P的耐性较高，随土壤P量增加，单叶面积减小而叶片数量增加。地果对土壤K含量不敏感。结论]该研究为人工栽培地果时土壤条件的控制提供参考。

| Abstract: | Objective] The study aimed to make the correlation analysis between leaf traits of Ficus tikoua Bur plant and the main soil ecological factors.Method] Based on an investigation on wild F.tikoua in wild land,the effect of main soil ecological factors as the water,N,P,K and organic C on the leaf traits of F.tikoua were studied.Result] The water content in soil was the most important factor that influenced the leaf area and leaf number significantly.With the rising of water content in soil,the leaf of F.tikoua became longer and wider,leaf area and inter-node length were increased and the leaf number was reduced.The soil N and organic C content had no significant effect on the leaf traits of F.tikoua.The soil N showed no significantly negative correlation with the leaf number and no significantly positive correlation with the inter-node length,showing that F.tikoua was resistant to soil impoverishment.F.tikoua had higher tolerance to soil P.With the increment of P content in soil,the leaf area was decreased and leaf number was increased.F.tikoua was not sensitive to soil K content.Conclusion] The study provided reference for control of the soil conditions in artificial cultivation of F.tikoua. |
