Abstract:
‘Tianhong 2’ ‘Jizhen 2’ ‘Baleng Crabapple’ were used as materials，three load levels were designed (T1,0.6 fruits per square centimeter dry cross-sectional area；T2,1.4 fruit per square centimeter of dry cross-sectional area；T3,2.2 fruits per square centimeter of dry cross-sectional area).The effects of different loadings on mineral elements and fruit quality of Fuji apple leaves and fruits on ‘Jizhen2’ interstock were studied，in order to provide reference for the orchard managment.The results showed that with the increase of load，the fruit weight，longitudinal diameter and transverse diameter increased gradually，the fruit hardness increased gradually，the soluble solids content decreased gradually，and the fruit surface brightness (L) increased first and then decreased.The load had little effect on the fruit malic acid content，fruit redness (a) and yellowness (b).The contents of nitrogen，phosphorus and magnesium in leaves of T2 treatment were at a high level，and the contents of iron，zinc and manganese in leaves of T3 treatment were at a high level.In terms of mineral elements in fruit，compared with the other two treatments，T1 treatment had the highest iron and boron content in fruit，T2 treatment had the highest nitrogen and potassium content in fruit，and T3 treatment had the highest phosphorus,calcium and copper content in fruit.The load had little effect on the content of magnesium and zinc in fruit.The correlation between mineral elements in leaves and fruits will vary with different loads.Therefore，for different loads，the content of mineral elements in fruits can be regulated by regulating the level of mineral elements in leaves.
