生物复合菌剂在西藏发酵有机肥研究

Fermenting Organic Fertilizer by Biological Compound Bacteria in Tibet

通过添加5种不同的生物复合菌剂,以羊粪、油渣和酒糟为原料,在西藏拉萨进行生物有机肥发酵试验研究,并用腐成的5种生物有机肥进行燕麦种植试验,结果表明:在西藏添加复合菌剂进行发酵有机肥产品基本可以达到有机肥国家生产标准;添加M3菌剂处理发酵后生物有机肥有机质含量和总养分含量较高;M5处理有机肥施用后燕麦产量最高;施用生物有机肥能够显著增加土壤有机质含量,增加土壤中放线菌和真菌数量,活化土壤养分使土壤水解性氮和有效磷含量显著增加。

5 kinds of biological compound bacteria were added to organic wastes including sheep dung,oil residue and liquor to study the fermentation organic fertilizer in Lhasa,the finished products were used for oat planting test.The results show that:the organic fertilizer fermented by adding compound bacteria substantially meets the national production standard of organic fertilizer,the finished product has a high content of organic matter and total nutrient by fermentation of adding M3 bacteria,the highest oats yield is achieved after M5 fermented organic fertilizer.Soil organic matter could increase significantly while actinomycetes and fungi in the soil have obvious growth after using bio-organic fertilizer,activating soil nutrients to dramatically increase hydrolysable nitrogen and available phosphorus.
