Abstract:

In order to optimize the fertilizer application amount and proportion of high-quality grapes,the effects of different nitrogen(N),phosphorus(P),potassium(K),calcium(Ca)and magnesium(Mg)treatments on external quality index(including spike length,longitudinal diameter,transverse diameter,berry shape index,cluster weight and single grain weight),color indicators(including L*,a*,b*,C,color index),internal quality indicators(including total soluble solid content,fruit firmness,titratable acid content,vitamin C)of Sunshine rose grapes were studied by L16(45)incomplete orthogonal experimental design.The results of comprehensive fruit quality evaluation showed that T10 treatment had a strong effect on the improvement of transverse diameter,cluster weight,a* and color index,and the cluster weight of T10 treatment was 844.3 g,which was significantly increased by 10.5%(T15)-55.8%(T4)compared with other treatments except of T11 and T12 treatments.T1 treatment had a strong effect on the increase of longitudinal diameter,and its longitudinal diameter is the largest(31.27 mm).T16 treatment had a strong effect on improving titrable acid content,vitamin C and fruit firmness,among which T16 treatment had the highest fruit firmness(4.93 N).Based on the comprehensive quality of fruits,the optimal theoretical formulation of N,P,K,Ca and Mg was N3P3K4Ca1Mg1,and the optimal dosage of N,P2O5,K2O,CaO and MgO were 6.8,6.3,14.2,0,0 kg for producing 2 000 kg fruits,respectively.In production practice,the optimal fertilization scheme should be determined according to the soil fertility status.
