Statistical analysis was performed on the climatic resources and main meteorological disasters of various growth periods of crisp pear in Henan province Ningling county demonstration park in 2017, and score calculation was performed. The results show that the climate resources during the key growth period of this year can meet the growth of fruit trees and fruits. There are sufficient light and heat resources, sufficient precipitation during the young fruit period and fruit expansion period, and the main meteorological disasters are high temperature heat damage and drought in midsummer.
