Abstract: In the era of "Internet + Agriculture", user experience is an important factor in determining the quality of agricultural service websites. Based on the analysis of the user experience of the agricultural service website, the task performance is used as the basis of user experience evaluation. The task performance evaluation index of agricultural service website is explored, and the user experience evaluation model based on task performance is constructed. Finally, with the evaluation model, the experimental results of the comparison of the "Xinghua Crab Net" and the optimized "Crab House" show that the user experience of the latter is obviously better than the former.
