Abstract:
In order to promote soilless culture,different proportions of oyster mushroom residue,cow dung and rice husk were carried out in this study,taking peat and vermiculite(volume ratio 3∶1)as the control to study the effects of different formulas on the growth,yield and quality of tomatoes.The results showed that the biostroma prepared from total waste could reach the cultivation effect of commercial stroma,and the treatment of P3 and P4(bacterial residue∶cow dung∶rice husk∶ratio was 4∶3∶3 or 3∶3∶4)could obtain a better effect,and the yield and vitamin C content of P4 increased by 2.0% and 6.3%,respectively,compared with the control group.Rich nutrients and trace elements in biological matrix contribute to crop growth,but attention should be paid to its salt content.
