摘要

The present experiment investigated durability during the repetitive use of washed rice straw, as bedding material, and washing water as a model study. Residual nitrogen levels, elasticity, and water suction rates for washed rice straw-adhered urea were measured. In addition, outflow levels of nitrogen and mineral ions (Na+, NO2-+NO3-, SO42-, PO43-, Cl-) for washing water were measured to determine durability. Nitrogen levels of rice straw significantly (P<0.05) decreased after two washings. There was no significant change in elasticity of repetitively used rice straw. Suction rates of rice straw after the second and third washings increased significantly (P<0.05) compared to the first time. With regard to the number of washings, the mineral ion outflow level in the washing water for nitrogen, Na+, NO2-+NO3- and PO43- after each washing was not significant. However, nitrogen outflow level tended to decrease after the third washing. SO4- and Cl- did significantly decrease (P<0.05) with the number of washings. In this study, it was considered that rice straw and washing water could be used repetitively three times. Furthermore, in order to maintain effluent standards, washing water from the first washing needs to be processed in a septic tank.
