- Abstract
In order to explore the relationship between fruit diameter and yield of red Fuji apple and environmental meteorological conditions, using the fruit diameter,single fruit weight,yield of red Fuji apple and environmental meteorological data in Wanrong from 2011 to 2020, the main environmental meteorological factors closely related to fruit diameter and yield were selected by the method of mathematical statistical analysis, and the multi-regression equation was established.The results showed that there was not obvious difference between transverse diameter and longitudinal diameter of red Fuji apple in young fruit,the growth rate of transverse diameter was greater than that of longitudinal diameter after mid June,and it initially presented partial circle or oblate circle in appearance.After late August, the growth rate of transverse diameter reached the peak, and the fruit increased the fastest.The ratio of transverse and longitudinal diameter was basically finalized by mid September.The fruit diameter was greatly affected by air temperature and precipitation, was positively correlated with the temperature in a specific period, and the precipitation in early August was significantly positively correlated with the transverse diameter.The yield was greatly affected by air temperature and sunshine, was positively correlated with precipitation in April and the relative humidity in early August. In production, increase of irrigation in April is necessary for enhancement of the fruit diameter and increase of yield.
