摘要

Compost production systems have changed considerably from windrow to bunker phase Ⅰ, followed by introduction of phase Ⅲ. Variations in composition of chicken manure and structure of straw can influence formulation. The present study was aimed at identifying a range of the quality parameters, which could identify changes during production due to variations in the composition of raw materials. Monitoring of parameters during phase Ⅰ, Ⅱ, Ⅲ of composting was carried out using 83 batches. Commercial yields harvested from the batches. Optimal parameters for pH, ammonia, total nitrogen, moisture content, ash and C:N ratio were identified. A model for prediction of potential yield of phase Ⅲ was generated from data set and validated using 10 samples. A new model consisting of the calibration and validation samples explained 81% of variation in mushroom yield (r~2 = 0.81), with a standard error for calibration of 1.59 kg/m~2. The evaluation of compost parameters during production to optimize substrate quality is discussed.
