Abstract:
Based on meteorological conditions, physiological and biochemical indicators of Tieling
Corylus heterophylla Fisch from shady and sunny slopes were investigated, and key meteorological factors affecting quality of
Corylus heterophylla Fisch were analyzed．Through expert argumentation, comparative analysis, and use of index-weighted summation method, key factors influencing climate quality of
Corylus heterophylla Fisch were determined, and an evaluation index model for
Corylus heterophylla Fisch climate quality was established．Results showed that there were five key factors affecting climate quality of Tieling
Corylus heterophylla Fisch, namely frost damage during flowering and pollination period, drought during fruit growth and development period, annual sunshine hours, diseases, and insect pests．Expert decision-scoring method was used to determine weight coefficients as 0.10, 0.30, 0.30, 0.15, and 0.15, respectively．A theoretical basis for creating "climate ecological superior products" and climate quality evaluation and certification work was provided．
