Abstract: In order to quantitatively evaluate the influence of meteorological conditions on the coloring quality of red kiwifruit, the red kiwifruits in the main kiwifruit producing areas in Sichuan province are selected, and the climate conditions of kiwifruit coloring are studied by means of experimental sampling, field investigation, regression analysis and comparative analysis. The results show that: The coloring of red kiwifruit and microclimate environment factors are closely related. Coloring of red kiwifruit in greenhouse, above 650 m, with good environmental permeability and bagging is better. When the daily temperature range is 13.9 ℃ and above, and the minimum daily temperature is less than 21.6 ℃, it is conducive to coloring.
