摘    要:堆肥过程中的氮损失及其控制正引起国内外越来越多学者的关注.受堆肥物料组成、pH值、通风/温度、湿度和堆肥添加剂等的共同影响,C/N质量比低的物料在好氧堆肥过程中会产生大量的氮损失(约为16%~74%).目前控制氮损失的方法,除了改变工艺条件,如保障适量的通风/控温、加湿等,主要就是在堆肥过程中加入添加剂.加入的物质主要有4大类:富含碳的物质,如秸杆、泥炭等;金属盐类及硫元素;吸附剂,如沸石、黏土、椰壳纤维等;外源微生物,如固氮菌、纤维素分解菌、EM菌等.今后堆肥过程中的氮损失调控将向各方法的优化和集成方面发展.

关 键 词:堆肥    损失控制

Abstract:Nitrogen loss usually occurs in composting of wastes, which is dependent on the composition, pH, aeration/temperature, moisture and compost additives, etc., especially in the cases of low C/N with a loss of 16%-74%. Effective reduction of such may be realized by addition of compost additives, or by using the appropriate aeration/controlling temperature and moisture. The additives may be classified into four types: rich carbon, such as crop stem, turf; metallic salt and sulfur; absorption including zeolite, clay, coconut shell; and inoculating microbes such as azotobacter, cellulose degrading bacteria, EM and so on.The control of nitrogen loss during the composting will be developed in the pattern of optimization and integration of various methods and techniques.
Keywords:composting  nitrogen  loss control
