Abstract:
In this study,the 4,5,7 years old layered spindle spur-type ‘Red Fuji’ apple trees were used as test materials,by analyzing architecture,branch quantity,canopy structure,fruit yield and quality of the different tree-age.The growth dynamics of canopy,fruit yield and quality of the layered spindle apple from the juvenile period to full bearing period were studied.The results showed that the tree height,canopy height,canopy diameter,canopy volume,stem circumference,coverage rate,LAI,MTA,total branch quantity increased with the growth of tree-age,of which,the tree height,canopy height,canopy diameter,canopy volume,stem circumference,coverage rate of 7 years old trees were significantly higher than that of 4 and 5 years old trees.The branch number of different ages increased by one times.The total branches of the 4,5,7 years old trees reached 116 325 branches per hectare,264 000 branches per hectare,735 900 branches per hectare.However,the ratio of different branch types did not change much,and the proportion of short branches was higher than 70%,which was the key to early fruiting and high yield.The difference of fruit quality between different canopy locations on the same tree-age was not obvious,but the difference of fruit quality between different tree-ages was significant,and the fruit yield and quality were also increased with tree-age.
