积雪变化对东北农田黑土盐基离子及有效硅铝含量的影响

Shuitu Baochi Xuebao
[目的] 为探究冬季积雪深度变化下东北农田黑土盐基离子及有效硅铝含量的季节性变化特征。[方法] 采用人工控制积雪深度的方法,通过测定除雪处理组(SR)、减雪处理组(SL)、自然积雪对照组(C)、增雪处理组(SA)的东北农田黑土环境因子(温湿度、含水率、pH、总有机碳)、盐基离子、有效硅以及活性铝,分析土壤盐基离子及有效硅铝的含量变化过程,以及两者对土壤环境因子的响应关系。[结果] 积雪深度的降低使季节性雪被覆盖下黑土受到积雪的保温作用减弱,0—30 cm土壤温度及湿度(未冻水含量)显著下降 ...
