中文摘要 | 本研究為探討琉球松菌根對煤礦棄土地土壤與土壤水化學性質之影響。試驗地位於臺北縣平溪鄉菁桐村煤礦,1989年於該煤礦棄土地上栽植接彩色豆馬勃(Pisolithus tinctorius (Pers.) Coker & Couch.)之琉球松(Pinus luchuensis)菌根苗,生長良好,設為植生;未接種菌根菌之硫球松則完全無法於礦區棄土地生存,全數枯死,設為裸露地。琉松菌根植生地與裸露地土壤之pH值皆為極酸性,凱氏全氮、有效磷含量、有機質之含量皆甚低,無機態硫含量甚高,裸露地之無機態硫含量(173.85 mg/g)較植生地含量(101.65 mg/g)為高,証實琉球松菌根對礦區棄土含硫量有極重要之影響。植生地與裸露地土壤溶液之SO42- K+ Mg2+ Ca2+ Al3+濃度變化,隨著土壤深度增加而增加,PO4-濃度過低無法測得,NO3- F-離子濃度隨著土壤深度而降低,煤礦棄土地含有大量之SO42- Al3+離子則較1995年之測定結果大幅降低。 |
英文摘要 | The purpose of this study was to investigate soil chemical and soil solution influenced by Luchu pine (Pinus luchuensis) with ectomycorrhizae on coal mine spoils. The study site was located in Jing-Torng, Ping-Shi village, Taipei county, north Taiwan. The coal mine was characterized by rugged topography and fragile geological formation. These harshly physical conditions together with the large amount of aluminum and sulfate in soil would increase soil acidity. Therefore, vegetation was very difficult to service in this site. In 1989, Luchu pines inoculated wit Pisolithus tinctorius, as the plantation soil (PS), were planted and growth very well. However, those non-inculated Luchu pines, as the bare-soil (BS), were all dead. In general, the pH of soil which collected from both PS and BS were very acid. Kjeldahl nitrogen, availability p and organic mater were also very low, but the contents of inorganic S were very high. The amount of inorganic S in BS (173.85 mg/g) was higher than those in PS (101.65 mg/g). The result proved that mycorrhizal Luchu pine play a very important role in this high S-containing soil. The concentrations of SO42-, K, Mg2+, Ca2+ and Al3+ in both PS and BS soil solution increased with depth of soil. The concentration of PO43- was too low to detect in this studied soil. On the contrary the NO3- and F- ions concentration were decreasing with the depth of soil. In coal mine soil, soil solutions had high SO42- and Al3+ concentrations, but were largely decreased when compare with those data in 1995. |
