| 摘 要： | 为探讨喀斯特山地土地整理后有效的土壤培肥模式,揭示不同粒级组分中养分含量的分布,以贵州省普定县陈家村进行土地整理后的坡地为例,进行小区施肥种植试验,研究不同施肥方式对整理后岩溶土壤养分培肥的影响。结果发现,各培肥模式中,施用农家肥、深松、使用本地蚯蚓对土壤有机质、全氮的改善效果较好,施用农家肥+尿素+过磷酸钙+氯化钾对增加土壤磷、钾养分的效果较好。同时发现0.002~0.02mm粒级组分中有机质和养分含量普遍高于其他粒级。 |

| Abstract: | The purpose of this paper was to study the effective fertilizer application modes in the Karst slope land after land consolidation, and to analyze the contents of nutrients in different soil particle fractions. A slope land in the Chenjiazhai Village of Puding County, Guizhou Province, China was involved, in which different fertilizers at different rates were applied. Among different fertilizer application modes, the farmyard manure mode, subsoiling mode, and local earthworm mode, made a good effects on the... |
