Study on Waste Cabbage Leaves Compost by Adding used Shiitake Growth Bag
Waste cabbage leaves
Shiitake Growth Bag
The demand for vegetable and agricultural products is increasing with the economic development in Taiwan. The processing of large vegetable wastes is becoming more and more important. The methods of treating vegetables wastes in general engineering include incineration, sanitary burial and composting. In this study, the self-developed experimental fermentation tank was used, and the highest amount of cabbage in the vegetable waste was selected as the main material of fermentation. The waste shiitake growth bag was used as the auxiliary material. The important factors such as temperature, pH value, conductivity, water content, C / N ratio and organic matter content, etc., were measured and recorded during the process of composting by adjusting the proper moisture content, ventilation volume and stirring frequency. To explore the main materials and sub-materials of the weight ratio and its ventilation frequency on the impact of composting. This study was carried out at a stirring frequency (stirring 0.5 hr-stop 7.5 hr), main materials and sub - materials with higher weight mixing ratio (2: 1) and lower weight mixing ratio (5: 1) and high frequency ventilation (ventilation 0.5 hr-stop 1.5 hr) and low frequency ventilation (ventilation 0.5 hr-stop 7.5 hr), to explore the effect of these factors on composting. The results showed that there were significant fermentation trends in the high mixing rate (2: 1 weight ratio) of the cabbage waste and the waste mushroom growing materials, and the high mixing rate of the mixing method was better than the low mixing rate in the performance of the fermentation parameters, but the addition ratio is too high, it will cause the conductivity of more than 4 mS / cm. Increase the ventilation frequency can increase the flow of oxygen, but because of insulation is not easy, excessive ventilation frequency will cause the fermentation temperature to decrease.
