Screening fruit and vegetable cultivation recipes for waste grape branch recycling using compound substrate
[Objective]This study aimed to develop a complex matrix for the cultivation of fruit veg-etables through compost treatment of grape branches,The goal was to screen the optimal matrix formula that supports the growth and development of fruit vegetables,thereby providing a theoretical foundation for the recycling of waste grape branches.[Method]The physicochemical properties of fermented grape branches,grass char,and perlite were compared across five different volume ratios:20∶50∶30(T1),30∶40∶30(T2),40∶30∶30(T3),50∶20∶30(T4),and a commercial control(CK),The growth characteristics and quality indexes of three kinds of vegetables(cucumber,eggplant and tomato)planted in these matrices were deter-mined,followed by a correlation analysis of each index.[Result]The physicochemical properties of the vari-ous substrates were found to be within the suitable range for fruit vegetable cultivation,Compared to CK,the yield-to-input ratio for cucumber and eggplant in T3 was 0.64 and 0.38,respectively,For tomato,the T4 yield-to-input ratio difference was 3.02,The daily temperature range of the matrix for T3 and CK was 6.01℃and 5.75℃,respectively,On a typical cloudy day,the average substrate temperature for T4 was 1.17℃higher than that for CK,Significant or highly significant correlations were observed between the growth and quality indices of the three types of vegetables and the substrate characteristics,The highest cor-relation for cucumber was with matrix total phosphorus content,for eggplant with matrix electrical conduc-tivity(EC)value,and for tomato with matrix available nitrogen.[Conclusion]Cucumber and eggplant ex-hibited better growth and development under the T3 treatment,whereas tomato showed improved growth and development under the T4 treatment,The composite matrix developed through treatments T3 and T4 can be recommended for the cultivation of fruit vegetables using waste grape branches,offering an innova-tive approach to the reuse of vineyard waste.
