Abstract:
Taking‘Red Fuji’apple trees of 16yearold as test materials，the effect of different improving stem on the net photosynthetic efficiency，effective relative light intensity，yield and quality were studied.The results showed when the height of stem was ≤100 cm，with the increasing of stem height that‘Red Fuji’apple’s net photosynthetic efficiency，effective relative light intensity，yield and quality significantly increased；When the height of stem was＞110 cm，with the increasing of stem height that the net photosynthetic efficiency，effective relative light intensity and quality had a slight increase but no significant differences and the yield began to decrease.When the density was 3 m×4 m，that the stem height of full fruit period apple was 100-110 cm was a good index of cultivation of adult‘Red Fuji’apple cultivation in the Longnan mountainous area of Gansu.
