Abstract:

The objective is to explore the reasonable fertilizer and pesticide managements for greenhouse tomato production by studying the effects of different fertilizer and pesticide applications on soil health, tomato quality and yield. In this study, two pesticide levels (conventional pesticide P1 and no pesticide P0) and five fertilization treatments (no fertilizer CK, conventional chemical fertilizer F1, farm manure combined with chemical fertilizer F2, farm manure and biological fertilizer combined with chemical fertilizer F3, perishable waste organic fertilizer combined with chemical fertilizer F4) were designed in the field experiment. The effects of different treatments on soil properties, soil enzyme activity, fruit quality and yield of tomato were analyzed. The results showed that the application of pesticides had a significant effect on soil properties and tomato quality. The soil organic matter content, total nitrogen content, soil urease, sucrase and catalase activities of P1 treatment were significantly decreased, while the vitamin C content, soluble sugar content, sugar acid ratio and fruit yield of P1 treatment were significantly higher than those of P0 treatment. Under the same pesticide level, fertilization had a significant effect on soil enzyme activity and pH value. Compared with the CK, soil pH value decreased significantly under P0F1 treatment, while the organic fertilizer application can slightly increase soil pH value. At the same time, soil nutrients of fertilization treatments were slight increased than CK, but there was no significant difference among the fertilization treatments. F2 treatment significantly increased soil urease, sucrase and catalase activities than CK. Followed by F3 treatment, it also significantly improved these soil enzyme activities, but F1 treatment had the lowest soil enzyme activity. For tomato nutrition, fertilization treatments can significantly increase vitamin C content, soluble sugar content and sugar-acid ratio than CK, but no significant difference was found among the fertilization treatments. Integrated all indicators, F3 treatment with significantly lower nitrogen fertilizer showed similar good effects on soil properties, tomato quality and yield with other fertilization treatments. Therefore, it is recommended F3 treatment as the suitable fertilizer management for greenhouse tomato planting, that is, farm manure combined with biological bacterial fertilizer and a small amount of chemical fertilizer. In order to get good tomato yield and quality, applying appropriate pesticides is also suggested.
