Abstract:

To provide a theoretical basis for the high-quality production and precise fertilization of Merlot grapes,through the determination of the mineral element content of each growth and different tissue parts,and the nutritional diagnosis and analysis based on the quality index formed by the phenolic substances in the fruit.The comprehensive quality index of fruit phenolics,namely CI value,was calculated by Topsis analysis method.By comparing the correlation between content of various mineral elements in different growth stages/ tissues and CI value,the nutritional diagnostic factors are determined.In order to provide a theoretical basis for the high-quality production and precise fertilization of Merlot grapes,high-CI vineyards were classified by CND method.The results showed that there was a significant synergistic and antagonistic relationship among the mineral elements in the leaves,petioles and fruits of the Merlot grapes.VS_F_N,MS_F_P,VS_F_K,VS_L_Ca,FBS_F_Mg,VS_F_Fe,FBS_L_Mn,MS_F_Zn,FBS_P_Cu,VS_P_B,FBS_L_Mo were selected as plant nutrition diagnostic factors.The quality index inflection point value of high-CI vineyards was 0.735 5,of which 7 orchards met this condition,accounting for 14.58% of the overall sample.According to the mineral element content range of Merlot plant within high-CI vineyards,the appropriate values of nutritional diagnostic factors were:N(8.85—11.81)mg/g,P(1.98—4.26)mg/g,K(14.97—20.70)mg/g,Ca(35.57—68.83)mg/g,Mg(3.69—15.51)mg/g,Fe(70.96—103.26)mg/kg,Mn(166.20—277.67)mg/kg,Zn(10.71—20.27)mg/kg,Cu(9.54—14.90)mg/kg,B(11.44—17.07)mg/kg,Mo(0.69—1.60)mg/kg.The nutritional diagnosis of high-CI vineyards showed that the K,Ca,Mn,and Mg in Merlot plants were on the low side.The obtain the highest fruit quality index as the goal,the recommended fertilizer rates per hectare were N 62.25 kg,P2O5 46.50 kg,K2O 0.00 kg,CaO 56.25 kg,and MgO 46.50 kg.Ca and Mg fertilizers should be applied in small amounts and multiple times;we should strengthen the management of water and fertilizer in the orchard to increase the absorption of K element by the tree.Through foliar spraying,the lack of Mn elements can be appropriately supplemented.
