摘要： 为解决发酵床网上肉鸭养殖过程中鸭粪排放导致的污染环境和降解问题，提出一种基于传感器对垫料性能监测系统。利用简单克里金插值法(simple Kriging, SK)，研究鸭舍发酵床垫料的温湿度空间分布，并结合发酵床内温湿度实际测量值进行交叉验证。结果表明：鸭舍发酵床垫料温度和湿度的测量值与预测值的均方根误差(root mean square error, RMSE)分别为0.292 2 ℃、0.68，平均偏差(mean bias error, MBE)分别为-0.015 ℃、-0.017，决定系数(coefficient of determination, R2)分别为0.970 7、0.987 5。整体鸭舍发酵区域集中在设施中部，最高维持在45 ℃以上，靠近出风口处基本趋于室温，发酵床发酵周期约200 h。基于此方法，不仅可以确定发酵床垫料腐熟规律，还可以通过垫料环境分布情况来为发酵床管控提供数据基础。

Abstract: In order to deal with environmental pollution and degradation caused by the discharge of duck manure during the breeding of meat ducks on fermentation beds, a sensor-based monitoring system for litter performance was proposed. By means of the simple Kriging (SK), the spatial distribution of temperature and humidity of the fermented mattress in the duck house was studied, and the cross-validation was carried out with the actual measured values of temperature and humidity on the fermentation bed. The results showed that the root mean square error (RMSE) of the measured value and the predicted value of the temperature and humidity of the fermented mattress material in the duck house were 0.292 2 ℃ and 0.68 respectively, the mean bias error (MBE) was -0.015 ℃ and -0.017, and the coefficient of determination (R2) were 0.970 7 and 0.987 5 respectively. The fermentation area of the whole duck house was in the center of the facility, and the highest temperature was maintained above 45 ℃, and the room near the air outlet was basically at room temperature. The fermentation period of the fermentation bed was about 200 h. With this method, could not only determine the maturation rule for the material of the fermentation bed, but also provide a database for the management and control of the fermentation bed by means of the environmental distribution of the bedding material.
