Abstract: 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.

摘要: 以台农1号杧果为试验材料,以常规管理为对照(CK),在杧果园再分别施入微生物菌剂0.5 kg/株(T1)、2.0 kg/株(T2)、3.5 kg/株(T3),生石灰1.0 kg/株(T4)、1.5 kg/株(T5)、2.0 kg/株(T6),生物炭4 kg/株(T7)、6 kg/株(T8)、8 kg/株(T9),分别研究微生物菌剂、生石灰、生物炭3类土壤改良剂对杧果果实产量和品质的影响。结果表明,与对照相比,3类土壤改良剂均能增加果实产量,提高杧果果实可食率、硬度及可溶性糖、维生素C、可溶性蛋白和可溶性固形物含量,降低可滴定酸含量。将3类土壤改良剂处理的果实产量与品质进行TOPSIS综合分析,各处理表现依次为T4>T5>T7>T6>T8>T1>T9>T2>T3>CK。根据TOPSIS分析分别选出3类土壤改良剂的最佳用量T4、T7、T1,对其处理过的杧果果实进行qPCR检验,发现3类土壤改良剂均可提高杧果果实中蔗糖合成酶基因MiSS1、MiSS2 及蔗糖磷酸合成酶基因MiSPS的表达量,促进杧果果实糖类代谢,提高杧果果实品质。表明一定用量的微生物菌剂、生石灰、生物炭处理对杧果果实产量和品质具有促进作用,进一步验证了土壤改良剂对杧果园酸性土壤的改良效果。
