The relationship between Litchi fruit growth process and the meteorological data such as temperature of the same period in continuous 3 years for an orchard is analyzed.The result shows that the time and length of the fruit growth period vary with various years,and its difference is related with the temperature conditions in the fruit growth duration.The big absolute value of the coldness-accumulated before the bloom will be helpful to promote the flower bud differentiation.The fruit growth process will be accelerated and the bearing fruit stage will be shorter with higher daily growth temperature in the duration from the bud to pulp arise,otherwise,the fruit growth process would be delayed and the stage will be lon-ger.But the days from pulp appearance to the fruit maturity are more stable.The statistic result shows that the accumulated growth temperature could more reflect the temperature influence on litchi fruit growth than effective accumulated growth temperature.
