Effects of Different Soil Amendments on Yield and Quality of Mango Fruit
With Tainong No.1 mango as the test material and routine management(CK)as the control,microbial agents 0.5 kg/plant(T1),2.0 kg/plant(T2),3.5 kg/plant(T3),quicklime 1.0 kg/plant(T4),1.5 kg/plant(T5),2.0 kg/plant(T6),biochar 4 kg/plant(T7),6 kg/plant(T8),8 kg/plant(T9)were applied to the mango orchard to study the effects of three types of soil amendments,including microbial inoculants,quicklime,and biochar,on the yield and quality of mango fruits.The results showed that all three kinds of soil amendments could increase fruit yield.Compared with the control,all three types of soil amendments could increase the edible rate,hardness,soluble sugar,vitamin C,soluble protein and soluble solids content of mango fruits,and reduce the titratable acid content.After conducting TOPSIS analysis on the fruit yield and quality treated with three types of soil amendments,the performance of each treatment was as follows:T4>T5>T7>T6>T8>T1>T9>T2>T3>CK.According to TOPSIS analysis,the mango fruits treated with the optimal concentrations of three types of soil amendments T4,T7 and T1,were selected for qPCR testing.It was found that all three types of soil amendments could increase the expression of sucrose synthase genes MiSS1,MiSS2 and sucrose phosphate synthase gene MiSPS in mango fruits,which could promote sugar metabolism in mango fruits and improve mango fruit quality.This study showed that treatment with a certain concentration of microbial inoculants,quicklime,and biochar could promote the yield and quality of mango fruit,which further verified the improvement effect of soil amendments on acidic soil in mango orchard.
