In this study, 20 tobacco-rice fields, 20 single cropping rice fields, 22 Chinese medicinal materials fields, 20 double cropping rice fields, 20 rice-rape fields and 20 rice-wheat fields were selected in September 2018, pH, soil organic matter (SOM), available phosphorus (AP) and rapid available potassium (RAK) of plough soil (0-20 cm) were analyzed, and then soil integrated fertility index (IFI) was calculated based on these four indicators in order to recommend the suitable fertilization for improving soil fertility by comparing the planting patterns. The results showed:1) pH of tobacco-rice was the highest, and pH of Chinese medicinal materials was significantly lower than those of other planting modes; SOM of double cropping rice was the highest, and SOM of Chinese medicinal materials was significantly lower than those other patterns; AP of Chinese medicinal materials was significantly higher than those of the other patterns, and single cropping rice was significantly lower than those of other patterns; RAK of Chinese medicinal materials and double cropping rice patterns were significantly higher than that of rice-rape patterns; IFI from high to low was double-crop rice (0.880) > tobacco-rice rotation (0.821) > single-crop rice (0.817) > rice-wheat rotation (0.760) > Chinese medicinal materials (0.693) > rice-rape rotation (0.645). 2) After comprehensive analysis and comparison of soil indicators, IFI values and net income, double-crop rice and tobacco-rice models were recommended. 3) For suitable fertilization, rice-wheat, single cropping rice and rice-rape patterns should pay attention to increasing the application of phosphorus, potassium and organic fertilizer appropriately; for tobacco-rice, 45% of the fields should continue to apply alkaline materials to change acid, and 15% and 45% fields should be added with organic and potassium fertilizers, 10% and 60% field should reduce organic fertilizer and phosphate and potassium fertilizer, and 15% and 45% fields should be added with organic and potassium fertilizers, 10% and 60% field should reduce organic fertilizer and phosphate and potassium fertilizer.
