In order to help Fuping dried persimmon climate quality evaluation and enhance market competitiveness,climate quality evaluation model of Fuping dried persimmon was established,based on the daily meteorological data of Fuping meteorological station from 1992 to 2022,growth period data and quality test results.Threshold range and weight coefficients of each meteorological index in key growth periods were determined by expert decision method,percentile method and weighted sum method.And the climate quality of Fuping dried persimmon in 2023 was evaluated with the model.Results show that,sunshine duration,average temperature,≥10℃accumulated temperature,precipitation during bud opening and leaf spreading period,sunshine duration,average temperature and precipitation during flowering period,and sunshine duration,daily temperature range and precipitation during fruit expansion period of persimmon,are the key indexes affecting the climatic quality of dried persimmon.The climate quality index of dried persimmon were graded as superior(≥2.2),excellent(1.8～2.2),good(1.5～1.8)and average(<1.5).Through the typical year test method,it was found that the evaluation results of the constructed climate quality model were basically consistent with the actual production,which could quantitatively reflect the influence of meteorological conditions on the dried persimmon quality.The climate quality index of Fuping dried persimmon produced in 2023 was 1.82,and the grade was"excellent".
