摘要

用盆栽试验研究了不同浓度的土壤侵蚀磁性示踪剂对土壤理化性状、微生物量及小白菜生理特性、产量、品质的影响。结果表明

磁性示踪剂提高了土壤pH、电导率值以及速效钾含量

降低了小白菜对土壤碱解氮、速效磷的利用;显著提高了土壤微生物量碳、氮及碳氮比(p<0.05)

改善了土壤微生物学性状。低浓度(5%)的磁性示踪剂提高了小白菜的叶绿素含量

有效改善了小白菜叶片的光合性能。磁性示踪剂还显著提高了小白菜SOD、POD活性及MDA含量(p<0.05)

对CAT活性具有抑制作用。另外

磁性示踪剂降低了小白菜的产量

但低浓度(5%)处理改善了小白菜的品质

且Cu、Pb和Cd含量均在国家蔬菜食品卫生标准范围内

不会对食品安全构成威胁。

Abstract

In order to determine the effects of the soil erosion magnetic tracer on soil and plants

pakchoi(Brassica chinensis) grown in the pots was exposed to different concentrations of magnetic tracer on basic physical and chemical properties

microbial biomass of soil and on physiological characteristics

yield and quality of pakchoi.The results showed that

compared with CK

the soil pH

EC and available K increased significantly with the application of magnetic tracer

but the applications of available N and P were s...
