| 摘 要： | 本文的主要目的是探讨堆肥对砂壤土阳离子型微量元素-Fe，Mn，Zn，Cu可溶性的影响．通过试验并进行堆肥比例和时间因素的双因子统计分析得出Fe的可溶性随时间的延长而增加，可溶Zn和Mn由于堆肥的加入而减少，可溶Cu极低，实际不受堆肥施入的影响．

| Abstract: | The main objective of this thesis was to investigate the solubility of cation microelements in a sandy loam soil mixed with compost.The experiment was designed in two factors: 0, 0. 1, 0. 5,1, 5, 10 % of compost added to the soil for assessing the influence of amount of compost on the solubility of canon microelements Fe, Mn, Zn, Cu; 15, 30, 45, 60, 75, 90 days of incubation after amendment of the compost for evaluating the influence of time on the solubility of Fe, Mn, Zn and Cu. The extracting solution was 0. 01 M CaCl2 and 0. 01 M CuCl2 respectively. Statistical analysis was conducted to identify the variation tendency as rate of compost and as time.Soil pH slightly increased with rate of compost, but gently decreased with time. Extractable Fe increased with time. Soluble Zn and Mn decreased due to addition of compost. Soluble Cu was quite low and practically not affected by addition of compost. |
