【摘要】：探讨了不同有机物配施化肥对植烟土壤腐殖质碳的影响,旨在为衡量和评价不同有机物对植烟土壤质量和肥力的影响提供科学依据。结果表明,与单施化肥(T_1)处理相比,总体上腐熟麦秸秆(T_2)、生物炭(T_3)、芝麻饼肥(T_4)、牛粪(T_5)配施化肥处理土壤腐殖质总碳、富里酸碳、胡敏素碳的含量均有不同程度升高,增幅分别为13.71%、9.31%、12.57%、28.10%,24.35%、6.30%、13.73%、14.80%,10.93%、16.11%、3.96%、26.27%,另外,T_2、T_4、T_5处理土壤胡敏酸碳含量增加,增幅分别为10.56%、66.14%、103.93%;T_4、T_5处理土壤胡/富分别提高32.20%、63.93%,PQ(胡敏酸在腐殖酸中所占的比例)分别提高22.96%、48.95%。综上,有机物配施化肥能改善土壤腐殖质碳组分,牛粪配施化肥处理效果最好,生物炭表现最差。
[Abstract]:The effect of different organic matter combined with chemical fertilizer on humus carbon in tobacco planting soil was discussed in order to provide scientific basis for measuring and evaluating the effect of different organic matter on soil quality and fertility of tobacco planting. The results showed that the contents of total carbon, fulvic acid carbon and humin carbon in soil humus, fulvic acid carbon and humin carbon were increased by 13.71%, 9.31%, 12.57%, 28.10%, 24.35%, 6.30%, respectively, compared with those treated with chemical fertilizer alone (T 鈮，
