| 摘 要： | 本文就污灌对土壤-植物体系中有机质及N、P、K等的含量变化的影响进行了研究。结果表明:污灌可使土壤K素的含量增加幅度最大为27.0%,但由于氨的挥发、硝化及反硝化作用易造成氮素损失。土壤-植物体系对有机污染物有较强的净化能力。0～60!的土层对有机质、N、P有一定的富集作用,有利于植物吸收利用。而植物对K素的吸收利用率较低。植物对养分的吸收积累顺序为叶>根>茎,P>N>K素。从不同植物的吸收情况来看,榆树对养分的吸收则明显优于苹果树和山桃。相关分析表明:表层土壤中有机质与N、P、K含量密切相关。

| Abstract: | The influencesof sewage irrigation on changes in the content of O. M., N, P, and Kin the soil-plant system were studied. The results showed that sewage irrigation would increase the content of K about 27.0% at most. But loss of nitrogen was found due to volatilization of ammoniac, nitrificationand denitrification, and the soil-plant system had strong rectificationability on organic pollutants. The soil stratificationfrom 0 to 60 cm had enrichment capabilityon O.M., N and P, that was in favor of plant absorption, but absorptive availabilityfor K was decreased. The absorptive accumulationof nutrients followed the order leaf >root > stem, and P >N >K. It was found that the nutrient absorptionof elm had much superiority over that of apple tree and david peach. Correlation analysisillustrated that O. M. had prominent relationship with N, P and K content. |
