中文摘要：

以安溪县崩岗洪积扇农田为研究对象,采集不同培肥方式改良茶园的土样进行分析研究,探讨该地区沙化农田恢复过程中土壤颗粒组成及土壤养分的效应。结果表明：施化肥、施农家肥、施沼液肥、施沼液肥＋种植绿肥均能有效改善洪积扇土壤理化性质。沙化农田经培肥后,砾石、砂粒含量均显著减少（P〈0.05）,而粉粒、粘粒含量显著增加（P〈0.05）;土壤CEC、有机质、氮磷钾含量也均呈显著增加趋势（P〈0.05）。土壤CEC、有机质、氮磷钾含量与砾石和砂粒含量呈显著负相关,与粉粒和粘粒含量则呈显著正相关。经分析,施农家肥与施沼液肥＋种植绿肥总体效果较明显。

英文摘要：

By collecting soil samples in the tea garden which are were cultivated in a variety of fertilizing patterns and exploring explored soil mechanical compositions and soil nutrient changes in this region in the process of the farmland desertification restoration to analyze slope collapse in alluvial sector in Anxi County. The results showed that： Fertilizer, farmyard manure, biogas manure and biogas manure together with planting green manure are were prone to effectively improve soil physical and chemical properties of alluvial sector. After the improvement of the farmland soil fertility, gravel and sand content reduced significantly （P %0.05）, whereas silt and clay contents increased remarkably （P〈0.05）. Soil CEC, organic matter, NPK contents also showed a significant increasing trend （P〈0.05）. It showed negative correlation between soil CEC ＆ organic matter ＆ NPK contents and gravel ＆ sand contents, in contrast, positive correlation could be seen between silt ＆ clay contents and Soil CEC ＆ organic matter ＆ NPK contents. In conclusion, the effect of farmyard manure and biogas manure together with planting green manure was more obvious than the other after comparisons.
