| Abstract: To screen out a special substrate based on mushroom residue suitable for tomato cultivation in the suburbs of Beijing, different ratios of flammulina velutipes residue and tea tree mushroom residue with peat and water retention agent were used as tomato cultivation substrate. Through comprehensive analysis and comparison of tomato growth vigor, fruit setting habit, yield and morbidity, the treatment 5 with tea tree mushroom residue(peat+water retention agent)=3.56.5 performed best. The yield was 9 319.73 kg per 667 m2 and the plants had strong growth vigor, good commercial properties and low morbidity. Mushroom residue was more suitable as a special substrate for tomato cultivation in the suburbs of Beijing. |
