生物菌剂对烟用有机肥堆制腐熟的作用效果研究

主要研究了生物菌剂对烟用有机肥堆制腐熟指标变化的影响。结果表明,随堆肥的腐熟,添加生物菌剂处理堆温先升高至较高温度(>50℃)后降低,常规腐熟处理堆温基本保持不变;相同腐熟时间内,添加生物菌剂处理堆肥物料外观腐烂程度、碳氮比下降速度、硝态氮含量升高幅度、腐殖化指数和种子发芽指数上升速度均高于常规腐熟处理。添加生物菌剂进行烟用有机肥堆制仅28 d即达到安全施用要求。与常规腐熟处理相比,添加生物菌剂能明显缩短堆肥腐熟时间,提高堆肥腐熟质量。

Effect of Microorganism Inoculants on Manure Composting for Tobacco Planting

The effects of microorganism inoculants application on index of composting were studied in present paper.The results showed composting temperature increased at first(>50℃)and then decreased with the application of microorganism inoculants,wherase composting temperature of conventional composting changed little.The decay degree in composting materials,the reduction of carbon/nitrogen ratio,the addition of NO+3-N content,the increase of humus index and seed germination index were strengthened by the application of microorganism inoculants.Manure composting could reach the requirement of fertilize after 28 days of the composting period when applying the microorganism inoculants.The application of microorganism inoculants could improve the composting process and its quality.
