【摘要】：探討了不同有機物配施化肥對植煙土壤腐殖質(zhì)碳的影響,旨在為衡量和評價不同有機物對植煙土壤質(zhì)量和肥力的影響提供科學依據(jù)。結(jié)果表明,與單施化肥(T_1)處理相比,總體上腐熟麥秸稈(T_2)、生物炭(T_3)、芝麻餅肥(T_4)、牛糞(T_5)配施化肥處理土壤腐殖質(zhì)總碳、富里酸碳、胡敏素碳的含量均有不同程度升高,增幅分別為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處理土壤胡敏酸碳含量增加,增幅分別為10.56%、66.14%、103.93%;T_4、T_5處理土壤胡/富分別提高32.20%、63.93%,PQ(胡敏酸在腐殖酸中所占的比例)分別提高22.96%、48.95%。綜上,有機物配施化肥能改善土壤腐殖質(zhì)碳組分,牛糞配施化肥處理效果最好,生物炭表現(xiàn)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，
