Abstract:

In order to select rotation crops suitable for tomato in southeastern of Shanxi Province,we planted six cropsrotation patterns,namely maize(LVZm),zucchini(LVCp),peanut(LVAh),green onion(LVAf),okra(LVAe),and cucumber(LVCs),taking treatment with continuous tomato cultivation(LLLe,CK)as control. The changes in the microbial community structure and diversity in the ITS1 region of soil fungi were analyzed by Illumina Miseq high-throughput sequencing technology. At the same time,the quality indicators(soluble total sugar,organic acid content,sugar-acid ratio,Vc content,soluble protein,soluble solids,lycopene content,nitrate)and yield indicators(single fruit weight,yield)of the following tomatoes were measured. The results showed that Ascomycote was the dominant phyla in the 7 treatments,and the species and abundance were quite different,LVCs,LVZm,LVAh and LVAe increased the diversity index of fungal,while LVCp decreased the index. LVZm had better taste;LVAe and LLLe had the highest Vc content;no significant difference in soluble protein content;the content of soluble solids were the highest in LLLe and LVCp;the content of lycopene was highest in LVCp;LVAe had the highest nitrate content. The yields significantly increased in LVAe and LVCp patterns,and the quality of single fruit significantly increased in LVCp rotation. Principal component analysis(PCA)showed that the scores of quality and yield among different patterns from high to low were LVCp>LVAe>LLLe> LVAh>LVAf> LVZm>LVCs. In summary,crop rotation changes the soil fungal community structure,affects the index of the fungal,the quality and yield of tomatoes in subsequent crops. Based on various factors,zucchini and okra are the dominant rotation crops suitable for the growth of local tomatoes.
