Abstract:

Taking‘ sand∶slag=2∶1（V∶V）’formula as the CK，this experiment added different volume
of mushroom residue with 10%（T1），20%（T2），30%（T3），40%（T4）and 50%（T5）on this basis，and
studied the effects of combined substrates of sand，slag and mushroom residue on the yield and quality of eggplants.
The results showed that in winter-spring crop，the contents of soluble sugar and free amino acid in eggplant pulp
were significantly higher than that of the CK under T3 treatment. The content of ascorbic acid in eggplant pulp
under T4 treatment was significantly higher than that of the CK. The contents of anthocyanin，flavonoids and total
phenol in eggplant peel were also higher. In autumn-winter crop，the contents of soluble sugar，soluble protein
and free amino acid in eggplant pulp were significantly higher than that of the CK under T3 treatment. The ascorbic
acid content was significantly higher under T4 treatment. The contents of flavonoids and total phenol in eggplant
peel were significantly higher under T1 treatment. In both crops，the yield of T1 treatment was the highest，
increased by 5.5% and 11.2% than those of the CK，respectively. In summary，adding 10% mushroom residue
was most favorable for the yield forming of eggplant in both winter-spring and autumn-winter crops. While adding
30% or 40% mushroom residue were favorable for the fruit quality forming of eggplant.
