    摘要:

    采用盆栽试验研究不同用量的猪粪与化肥配施对植烟土壤酶活性和微生物生物量碳氮动态变化的影响。结果表明:植烟土壤中脲酶、过氧化氢酶、蔗糖酶活性和微生物生物量碳含量随栽培天数的增加呈动态变化,表现出先增加后减少的趋势,且在栽培10天或25天达到最高峰,各处理中以配施30% 猪粪 + 70% 化肥处理较好;微生物生物量氮含量随栽培天数增加表现出先下降后上升再下降的趋势,且在20天时达到最高峰,以化肥处理最好,配施处理以70% 猪粪 + 30% 化肥处理较好。综合所有指标,在该试验条件下,配施30% 猪粪 + 70% 化肥处理对植烟土壤酶活性和微生物生物量碳含量作用较好。

    Abstract:

    In this paper, the effects of pig manure and chemical fertilizer on the changes of soil enzyme activities and microbial biomass C and N of tobacco-planting soils were investigated with pot experiment. Results showed that the activities of soil urease, catalase, invertase and microbial biomass C changed with the increasing days of tobacco cultivation: they increased with cultivation days at first, and reached their maximum values in 10 days or 25 days, and then decreased with further increase in cultivation days. The treatment with 30% pig manure + 70% chemical fertilizer was better to increase the activities of these enzymes and microbial biomass C than other treatments. Microbial biomass N content decreased at first and then increased with the increasing cultivation days, and reached its maximum value in 20 days and then decreased with further increase in cultivation days. The treatment with only chemical fertilizer was the best one to increase microbial biomass N followed by the treatment with 70% pig manure + 30% chemical fertilizer. Considering all indexes comprehensively, we concluded that combined application of 30% pig manure and 70% chemical fertilizer was better choice to increase soil enzyme activity and microbial biomass C.
