Ecologicalization of Facility Tomato Growth in Beijing Study on Cultivation Substrate Screening
The purpose of this study is to screen out the ecological cultivation substrate suitable for tomato production in Beijing area.The ecological horticultural cultivation substrate was developed by using waste resources such as earthworm manure,mushroom residueand fly ash as raw materials,and the ecological cultivation substrate suitable for tomato production was screened out.Compared with the traditional cultivation substrate,the growth,yield,quality and water production efficiency of tomato produced by substrate 4(peat∶vermicompost∶organic fertilizer∶soil=3∶4∶1∶2)were the best.After 50 days of planting,the plant height of tomato cultivated by substrate 4 was the highest,which was 173.8 cm,5.33%higher than that of the control substrate(CK),and the difference was sig-nificant.The final yield was 29.31%higher than that of CK.Vc content and soluble solids content increased significantly,Vc content reached 207.8 mg·kg-1,7.8%higher than CK treatment,the difference was significant.The soluble solids content was 4.1%,which was 21.78%higher than CK treatment,and the difference was extremely significant.The water production efficiency was 31.32 kg·m-3,which was 30.71%higher than that of CK treatment.In conclusion,the ecological substrate with a mixture ratio of peat,vermicompost,or-ganic fertilizer and soil of 3∶4∶1∶2 is suitable for the growth of greenhouse tomato in Beijing.
