火烧频率对草原土壤养分及球囊霉素相关土壤蛋白含量的影响
Impact of Burning Frequency on Soil Nutrients and Glomalin Related Soil Protein in Grassland
摘要
Abstract
Objective] The study aims to reveal varying patterns of soil nutrients and glomalin related soil protein (GRSP) in different burning treatments by analyzing associations between soil nutrients and GRSP in grassland with different burning frequencies .This study will provide theo-retical basis for improving grassland vegetation and soil quality with using reasonable burning measure .[ Method ] Chinese wildrye grassland of different burning frequencies in Xilingol was selected as object.We determined some soil parameters,including soil organic carbon (SOC),total nitrogen (N),total phosphorus (P) and GRSP content.[Result] For SOC of 0-5 cm,there was a decreased trend with increasing burning fre-quencies.Lower burning frequency (every 4 years) could significantly increase SOC in 0-40 cm layer (P<0.05),while higher burning frequen-cy (every 2 years) could markedly decrease SOC in the same layer (P<0.05).Soil P and N were not affected by different burning treatments in 0-40 cm (P>0.05).Lower burning frequency (every 4 years) could increase EE -GRSP content in soil surface (0-5 cm) and T-GRSP content in 0-40 cm (P<0.05).Meanwhile,highly significant correlations among SOC,N and GRSP were observed(P<0.01).[Conclusion] Lower burning frequency could improve SOC sequestration in deeper soil layer and increase GRSP output and input ,which was mainly responsible for improving degraded grassland soil quality .关键词
