Abstract

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
