摘要
在静态通气条件下,以养殖场鸡粪、猪粪、牛粪为材料,小麦秸秆作为堆肥调节物质,分别研究了接种微生物菌剂(接种菌剂处理)和不加菌剂(对照处理)堆肥过程中蔗糖酶活性的变化特征及其与温度的关系。结果表明,接种菌剂处理与对照处理在堆肥过程中蔗糖酶活性的变化趋势基本一致,即在高温腐解期蔗糖酶活性持续较高,在低温腐殖化期蔗糖酶活性急剧下降,且维持较低水平。接种菌剂能明显地提高堆肥过程蔗糖酶的活性,酶活性峰值高且出现时间较对照早4～8d。供试的3种物料蔗糖酶活性差异不显著,接种菌剂处理鸡粪、猪粪和牛粪蔗糖酶活性的最高值分别为87.84、81.3和86.8mg·(g·d)-1,对照处理分别为62.9、60.9和63.79mg·(g·d)-1,但3种物料接种菌剂和对照处理酶活性峰值出现的时间不尽相同,鸡粪的两种处理相同,猪粪加菌剂比对照提早8d,牛粪加菌剂较对照早4d出现。整个堆肥过程中蔗糖酶活性与堆体温度变化关系密切,对照处理堆体温度与蔗糖酶活性的关系为一元二次方程,表现为高温腐解期为显著性直线负相关,低温腐殖化期为显著性直线正相关,而加菌剂处理堆体温度和蔗糖酶活性间为极显著直线正相关。
Changes of sucrase activities and temperatures in static animal excrement composting with added microbial agents were studied at aeration composting process. The animal excrement included cow manure, chicken manure and pig manure. Wheat straw was used to adjust the compost bulk. Results revealed that the patterns of sucrase activities were similar during the composting process for both treatments, it was bigger during high temperature decay process and smaller during low temperature humification period. Nevertheless, the peak values of the sucrase activities were bigger and occurred 4-8 days earlier with added microorganism agent than in the control. The peak sucrase activities in the treatment with added microorganisms were 87.84 mg· （g·d）^-1（ 10th d）, 81.3 mg· （g·d）^-1（8th d） and 86.8 mg· （g·d）^-1（ 10th d） for chicken manure, pig manure and cow manure, respectively, while the respective activities in CK treatment were only 62.9 mg· （g· d）^-1 （ 10th d ）, 60.9 mg· （ g· d ）^-1（ 16th d ） and 63.79 mg·（g· d ） ^-1（ 14th d ）, respectively. There wasn＇t any significant difference for peak sucrase activities among chicken excrement, pig excrement and cow excrement as composting materials. However, except sucrase activities of chicken excrement peaked at the same time for both treatments, while pig excrement with adding agent appeared 8 days earlier than in the control, and cow excrement occurred 4 days earlier than CK. There was a significant correlation between composting temperatures and sucrase activities for all treatments. An exponential increase was seen for CK, and a linear rise for the treatment with added microorganisms.
