Abstract:

In order to reveal the close correlation between the growth of cigar and meteorological factors in Laifeng of Hubei Province, based on the meteorological observation data of Laifeng in Hubei Province from 2008 to 2021, combined with the foreign data of some literatures, using the time distribution of nonlinear polynomial fitting and the linear trend change diagnosis and tendency rate to calculate and analyze the climate characteristics suitable for the growth of Laifeng cigar in different growing stages. The correlation between meteorological factors and meteorological yield was analyzed by using the separation calculation method of meteorological yield and Person correlation coefficient. The results showed that light and temperature were complementary, precipitation was moderate, light was suitable and monthly distribution was good in Laifeng cigar area, which provided excellent growth conditions for Laifeng cigar, and also provided reference for suitable meteorological factors in each period of development. It was proved that the comprehensive meteorological conditions of Laifeng cigar basically well met the demand of cigar quality development index.
