Abstract:

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.

Key words: Tibet, organic fertilizer, fermentation, biological compound bacteria
