钼矿开采对球囊霉素相关土壤蛋白和土壤化学计量特性的影响

以不同开采程度钼矿区根际土壤为研究对象，探索了钼矿开采对土壤球囊霉素相关土壤蛋白、化学计量特性及其两者之间关系的影响。结果表明，开采区土壤碳、氮含量分别为25.30和1.00 g/kg，显著低于恢复区和未开采区土壤的碳、氮含量。开采区土壤的碳氮比达到29.36，分别是恢复区和未开采区的2.02倍和1.30倍。恢复区和未开采区土壤的总提取球囊霉素含量为2.81和3.64 mg/g，易提取球囊霉素含量为1.22和2.02 mg/g，分别是开采区土壤总提取和易提取球囊霉素的2.08倍、2.70倍和1.97倍、3.26倍。此外，土壤碳、氮含量对丛枝菌根真菌分泌球囊霉素相关土壤蛋白有显著的影响。可见，钼矿开采主要导致了土壤碳、氮的大量流失，并对丛枝菌根真菌分泌球囊霉素相关土壤蛋白具有明显的抑制作用。

Effect of Molybdenum Mining on Glomalin Related Soil Protein and Soil Stoichiometric Characteristics

In this experiment, the response of soil globulin content to ecological chemical characteristics in molybdenum ore areas with different mining levels was investigated, in order to provide more theoretical basis and scientific basis for ecological restoration in molybdenum ore areas. In this study, the rhizosphere soil in molybdenum mining area was taken as the research object, and explored the influence of molybdenum mining on soil glomalin, stoichiometry characteristics and the relationship between them. The results showed that the soil C and N content in the mining area were 0.25 and 0.01 g/kg, respectively, which were significantly lower than the soil C and N content in the recovery and virgin areas. The soil C/N reached 29.36 in the mining area, which was 2.02 and 1.30 times that of the recovery area and virgin area, respectively. The TG content of the soil in the recovery area and virgin area was 2.81 and 3.64 mg/g, respectively, and the content of EEG was 1.22 and 2.02 mg/g, respectively, which were 2.08, 2.70 times and 1.97 and 3.26 times of the TG and EEG in the mining area, respectively. In addition, the results of regression analysis showed that soil carbon and nitrogen content had a significant effect on the secretion of GRSP by arbuscular mycorrhizal fungi. It can be seen that molybdenum mining mainly had led to a large loss of soil carbon and nitrogen, and had a significant inhibitory effect on the secretion of GRSP by arbuscular mycorrhizal fungi.
