Abstract:

To explore the temporal variations of climate suitability during different growth stages of juicy peaches and provide support for the sustainable development of the juicy peach industry in Ningbo, the suitability model of temperature, precipitation, and sunshine was established using the fuzzy mathematics method based on meteorological indices of juicy peaches and daily meteorological data. A climate suitability model was then established using the geometric average method. The results showed that the constructed climate suitability model can better describe and analyze the climate suitability of peaches, based on the climate yield verification. From the ranking results of the suitability of single meteorological elements, the temperature suitability is the highest, followed by the precipitation suitability, and the sunshine suitability is the lowest. The suitability of various climate factors has internal changes and a downward tendency. The sunshine suitability has the most significant downward trend, with a climatic tendency rate of -0.069/10 a. The suitability of temperature and climate is the lowest during the fruit-expansion period, with the highest coefficient of variation. The suitability of precipitation is the lowest and the coefficient of variation is the highest during the period from expansion to maturity. The sunshine suitability is the lowest during the hard core stage and has the highest coefficient of variation during the fruit-expansion stage. Except for the suitability of sunshine, all suitability during the nutritional recovery period is at a high level, with the lowest coefficient of variation. Therefore, there are significant temporal variations in temperature, precipitation, sunshine, and climate suitability at the different growth periods of juicy peaches, with the most significant changes occurring during the fruit-expansion period. Targeted cultivation measures should be developed in production to mitigate the impact of adverse climate conditions on the yield and quality of juicy peaches.
