| Abstract: | The applicability of attenuation index smoothing model for predicting soil moisture in vegetable greenhouses was investigated.The attenution index smoothing model was calibrated and validated by the measured soil moisture values of vegetable greenhouses in Chuanhang irrigation district,Suqian city.The results showed that compared with the Holt double parameters model,the attenuation index smoothing model provided better predictions and had higher accuracy for predicting soil moisture of vegetable greenhouse. |
