- 摘要:
- 崩岗是我国南方危害性极大的一种土壤侵蚀类型，尤其是产生的大量洪积物冲入农田，严重影响洪积扇农田质量。以苍梧县崩岗洪积扇为研究区域，采集洪积扇柑桔园不同培肥模式土样对其进行分析，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变化。结果表明：不同的培肥模式均能改良洪积扇土壤性质，土壤中的粉粒和黏粒含量有显著增加，养分含量也有显著提高。采用修正的内梅罗综合指数法对洪积扇土壤进行肥力评价可知，施化肥、施农家肥、种植绿肥+秸秆还田土壤肥力等级系数P值比对照区分别增加了42.11%，139.47%，135.53%，施肥模式以农家肥效果最佳。相关分析显示，土壤肥力指标与土壤砾石和砂粒含量呈显著负相关，而与粉粒和黏粒含量呈显著正相关。研究结果对改良崩岗洪积扇农田土壤，提高农业生产力和效益有重要的科学意义。
- Abstract:
- The collapse hills are a great danger of soil erosion types in southern China, especially, large quantities of alluvial material moving into the farmland seriously affect the quality of farmland alluvial fan. In this paper, Cangwu collapse of Gang alluvial fan area was studied. Soil samples were collected from different fertilization patterns under alluvial fan citrus groves for the analysis of farmland desertification in the region to explore the process of the composition change of the soil particles and soil nutrient recovery. The results showed that different fertility patterns could improve alluvial fan soil properties. Soil silt and clay contents and nutrient contents increased significantly. Nemerow composite index using the modified method of alluvial fan soil fertility evaluation showed that fertilizer, manure, green manure + straw soil fertility level coefficient P values increased by 42.11%,139.47%,135.53%, compared to the control area, the manure fertilization mode was the best practice. Correlation analysis showed that soil fertility index was significantly negatively correlated with and soil gravel and sand contents, and was significantly positively correlated with silt and clay contents. The results are of great significance to improve agricultural soils in collapse Gang alluvial fan, promote the understanding of agricultural productivity and efficiency.
