摘    要:研究了生物有机肥对土壤中磷的吸附和解吸特性的影响。试验结果表明,经过Langmuir方程拟合生物有机肥对土壤中磷的等温吸附特性,两种作物条件下,最大缓冲容量(KXm值)各处理的变化趋势相同,依次为:PMS(W富磷城市生活垃圾肥)HF>WSM>CK。

关 键 词:生物有机肥    吸附-解吸

Abstract:This paper studied effects of bio-organic fertilizers on phosphorus adsorption-desorption in soil under two kinds of plants(soybean and tomato).The experiment results show: the maximum buffering capacity(Xm·K) among different treatments followed the order: PMSW(P-riched municipal solid wastes)< HF(hen feces) < MSW(municipal solid wastes) < CK(chemical fertilizer);the intensity of absorbed phosphate in MSWP was the least,but its energy lever was the highest,and the phosphate supply capability was the highest among all four treatments.The percentage of phosphorus desorption over absorption for CK,MSW,PMSW and HF was 22.1%,22.54%,28.88%,25.31% under soybean and 19.01%,22.44%,24.23%,21.28% under tomato,respectively,resulting in the following ranking: MSWP > HF > MSW > CK in phosphoric desorption capacity.
Keywords:bio-organic fertilizer  phosphorous  adsorption-desorption
