摘要/Abstract

摘要：

磷供应不足是南方红壤区农、林业生产所面临的主要问题，为探究施用袋控缓释肥是否对提高磷素有效性及有效磷组分含量有显著正向效应，以广西国有高峰林场桉树人工林红壤为研究对象，设计袋控缓释肥常规施肥(G1)、袋控缓释肥减量施肥(G2)、传统复混肥(G3)、施用基肥(G4)、不施肥(G5)等不同肥料种类与施肥量对比试验，采用土壤磷分级方法测定土壤中磷素各组分含量，以冗余分析方法研究各组分对林木生长量的影响。结果表明：（1）相比传统施肥，袋控缓释肥处理显著提升了土壤中AP、Pi、Fe-P等组分含量；（2）G2、G1的磷活化系数显著高于其余3个处理，PAC排序顺序为G2>G1>G4>G5>G3；（3）冗余分析结果表明，PAC、Fe-P提升对植物生长量均有显著正效应。在南方红壤区桉树人工林经营过程中施用袋控缓释肥可以促进土壤中磷素的累积并提高磷活化率。袋控缓释肥具有较高磷素利用效率的机制可能是通过磷元素的持续输入以及阻隔磷元素与酸性土壤的接触进而减少磷素在土壤中的固定，达到保证林木生长过程中的磷素供给。

Abstract:

The insufficient supply of phosphorus is the main problem restricting agriculture and forestry production in red soil region of south China. To investigate whether applying bag-controlled slow-release fertilizer can improve the phosphorus availability and have a significant positive effect on phosphorus components’ content, with Eucalyptus plantation forest in Gaofeng State-owned Farm in Guangxi red soil region as the research object, we designed bag-controlled slow-release fertilizer with conventional fertilization (G1), bag-controlled slow-release fertilizer with reducing fertilization (G2), traditional compound fertilizer application (G3), basal fertilizer application (G4) and no fertilization (G5) to conduct the comparative tests, and used soil phosphorus classification method to determine the content of phosphorus components in soil. The results showed that: (1) compared with traditional fertilization, bag-controlled slow-release fertilization significantly increased the content of AP, Pi, Fe-P and other phosphorus components in soil; (2) the P activation coefficient of G2 and G1 were significantly higher than that of the other three treatments, the order was G2>G1>G4>G5>G3; (3) redundancy analysis showed that PAC and Fe-P had the most significant effect on plant growth among all phosphorus components. The application of bag-controlled slow-release fertilizer in red soil Eucalyptus plantation in south China can promote the accumulation of phosphorus and increase the phosphorus activity, and the mechanism of high phosphorus use efficiency is mainly through the sustained input of phosphorus and reducing phosphorus immobilization by obstructing the contact of phosphorus with acid soil to guarantee the phosphorus supply.

Key words: red soil, bag-controlled slow-release fertilizer, phosphorus component, traditional, fertilization, redundancy analysis
