油茶果壳改良材料对红壤有效磷的影响研究
Effects of the improved material of Camellia oleifera Abel shell on the Effective Phosphorus Content in Red Soil
摘要
Abstract
Isothermal adsorption was conducted to investigated the activation of phosphorus under the in-fluence of amelioration materials composed of shell of Camellia oleifera Abel,zeolite and polyacrylamide. The result shows that:shell of Camellia oleifera Abel improved material could significantly increase the available phosphorus content in soil.The content of available phosphorus in soil was increased with the increase of adding amount.The contents of Fe-P,O-P and Ca-P were significantly increased by different materials,but not due to the increase of adding amount.The results showed that the available phosphorus released from shell of Camellia oleifera Abel was fixed by soil,but the fixed amount was limited.The contents of available phosphorus in the soil applied with different improved materials of shell of Camellia oleifera Abel but the same adding amount were significantly different. Treatment 11 and 12 maintained a high soil available phosphorus content at different treatment times.The average available phosphorus content was 0.90 mg/kg,0.98 mg/kg,which was 5.6 times and 6.1 times that of the control,respectively,which was significantly higher than that of other treatments. Treatment 11 also had lower Al-P ,O-P contents compared to other treatments of the same addition,and treat-ment 12 had a lower Ca-P content.关键词
