Abstract:

To explore the effects of bio-organic fertilizer on the yield and quality of vegetable crops, tomato was used as the test material to investigate the influences of single bio-organic fertilizer, single application of chemical fertilizer, and bio-organic fertilizer + chemical fertilizer on facility soil nutrients, microorganisms, enzyme activity, yield, and quality under the condition of solar greenhouse by a randomized block experiment method. The results showed that compared with single application of chemical fertilizer, single application of bio-organic fertilizer and bio-organic fertilizer+ chemical fertilizer significantly increased the yield of tomato fruits by 27.28% and 47.56%, respectively. Compared with other treatments, single application of bio-organic fertilizer significantly increased the content of organic matter, alkali-hydrolyzed nitrogen, available phosphorus and available potassium in the facility soil, while clearly reduced the content of nitrate nitrogen. It significantly increased not only the three microbial groups of soil actinomycetes, fungi and bacteria, but also the activities of alkaline phosphatase, invertase, polyphenol oxidase and catalase. In addition, single application of bio-organic fertilizer also significantly increased the contents of lycopene and Vc in tomato fruit, and significantly decreased the content of nitrate compared with other treatments. It is suggested that bio-organic fertilizer can significantly increase the yield and quality of tomato, and effectively improve the fertility of the facility soil. The present study can provide a certain basis and reference for the production of pollution-free vegetables.

Key words: tomato, enzyme activity, lycopene, microbial population, bio-organic fertilizer
