| 中文摘要 | 本文对云南、贵州和安徽三省区紫色土有机胶体组成和特性作了初步探讨,其共同特点是:三省区紫色土有机质含量均小于1%,普遍低于贵州的对照土壤—黄壤的有机质含量;紫色土腐殖质的HA/FA值均小于1,比其对照土壤—黄壤HA/FA值高;紫色土结合态腐殖质中松结态和稳结态较紧结态低,紧结态占重碳的50%以上。并且还分析了有机胶体与土壤肥力的关系。 |
| 英文摘要 | The characteristics of organic matter ,humus and combined humus of purple soils from Yunnan , Guizhou and Anhui provinces were analyzed ,and were compared with that of yellow soil1The results showed : (i) the content of organic matter of some purple soils were less than 1% and lower than that of the yellow soil from Guizhou province; (ii) the ratio of humic acid to fulvic acid(HA/ FA) in purple soil was lower than 1 and higher than that of the yellow soil from Guizhou province; (iii) the percentage of the loosly combined humus (H1) and the stably combined humus (H2) were both lower than the tightly combined humus (H3) in purple soil; and (Ⅳ) the percentage of the tightly combined humus (H3) was over 50% in heavy fraction carbon. Furthermore,the relationship between organic colloid and fertility of purple soil was studied. |
