Abstract:

In order to use the wasted pseudostem effectively, the banana pseudostem was inoculated with the combining bacterial agents, and the effects of these external microorganisms on compost organisms and nutrients compound were investigated. Results showed that inoculating combining bacterial agents could increase the total number of microorganisms in the compost, and increase the quantity of organisms in early phase of composting and accelerate the decomposition of organic matter, thereby speed up the composting process. During the process of fermentation, the number of bacteria was higher than both fungi and actinomycetes significantly, and in the early phase of fermentation, the number of bacterial was around 100-1000 times, and 10-100 times higher than fungi and actinomycetes respectively. The complex strains increased the temperature of the composting pile and speeded up the arrival of high-temperature phase, and lengthened the sustainable time of high temperature, thereby enhanced the composting process. Compared to the control, the time for composting was shortened for 7 days with the combining bacterial agents. In addition, the combining bacterial agents could increase the amount of total nitrogen, available phosphorus and potassium, and after composting, rapid available potassium was 86.8% higher than before.
