The results showed that compared with conventional chemical fertilizer+rotary tillage（CK）,the application of soil conditioner and microbial organic fertilizer could garlic growth and development，reducing disease index，and increase yield. Among them，conventional chemical fertilizer+rotary tillage+microbial organic fertilizer+soil conditioner（T3）had the best effect.Compared with conventional chemical fertilizer+rotary tillage（CK）,the contents of soil organic matter，alkali hydrolyzable nitrogen，available phosphorus，and available potassium were increased by 22.06%，13.47%，18.80% and 14.89%，respectively，and soil powder was significantly increased. The activity of catalase，sucrase，phosphatase，and urease of soil was significantly enhanced，and the control effects of sclerotinia disease，leaf blight and root rot reached 63.36%，66.47%，and 60.15% respectively，which increased the height of garlic，stem diameter and garlic diameter，and the garlic yield was increased by 25.64%.In summary，the combination of soil conditioner and microbial organic fertilizer on the basis of conventional rotary tillage and chemical fertilizer（T3）has the best effect on soil improvement，disease prevention，and yield increase of the continuous cropping garlic.

The results showed that，the straw degradation rate of SM treatment was 73.1%，which significantly increased by 35.4—46.7 percentage points compared with WM treatments.Compared with WM treatments，the contents of cellulose，hemicellulose and lignin of residual straws of SM treatment significantly decreased by 40.7%—57.1%，29.9%—50.2% and 12.1%—17.3%，respectively.The soil water content of SM treatment significantly increased by 5.4—8.7 percentage points compared with WM treatments，soil bulk density of SM treatment significantly decreased by 9.4% and 6.5% compared with WM3 and WM6 treatments，and soil porosity of SM treatment significantly increased by 5.7 and 4.0 percentage points compared with WM3 and WM6 treatments.The contents of soil organic matter，available phosphorus and available potassium of SM treatment significantly increased by 17.7%—31.1%，42.2%—65.9% and 14.2%—24.5% compared with WM treatments，and soil alkali hydrolysable nitrogen content of SM treatment significantly increased by 18.5% compared with WM3 treatment. The yields of Stropharia rugosoannulata and maize of SM treatment were 33 543.1 kg/ha and 10 266.9 kg/ha，and maize yield of SM treatment significantly increased by 13.9%—22.9% compared with WM treatments，but maize yields were not significantly different among WM3，WM6 and WM9 treatments.The economic benefit of SM treatment increased by 96 600—99 100 Yuan/ha compared with WM treatments.In conclusion，Stropharia rugosoannulata‑maize rotation can not only promote straw degradation and improve soil fertility，but also increase economic benefit，so it is an effective measure to realize straw resources utilization and soil fertility improvement.

Soil samples were collected before sowing,plant samples were collected at the early flowering stage,and pH value,total salt,nutrient and mineral element contents were determined.The results showed that feed rapeseed could reduce the pH value,total salt and Na +contents of saline-alkali soil,and Na +was mainly concentrated in the root system of feed rapeseed.The contents of available phosphorus and available potassium in saline-alkali soil could be improved to a certain extent by planting feed rapeseed,but there was no obvious advantage in the increase of content of soil organic matter in the same year after planting feed rapeseed(harvest at early flowering).After planting feed rapeseed,the content of available Fe in soil increased significantly,while the contents of available Ca,Mg,B and Mn decreased significantly.In conclusion,feed rapeseed has certain effects on soil improvement in saline-alkali land,and can improve soil fertility and soil environment.

Shannon index of rhizosphere soil bacterial community of sorghum/corn rotation treatment was significantly higher than that of continuous cropping treatment.There was an obvious difference in the number of bands of fungus 18S.Specific bands were found in continuous cropping and applying biological agent treatments,indicating that the fungi gene Shannon index in 18S zone was higher in the rhizosphere soil of continuous sorghum.Applying biological agent and sorghum/corn rotation could alleviate the continuous cropping obstacles of sorghum to a certain extent, it should be noted that the effect of applying biological agent to continuous cropping soil had the best effect.

At 150 days after transplant,the incidences of southern blight and root rot of Atractylodes macrocephala were 61.97% and 91.67% lower than that of A1 B1 treatment,respectively.The average value of soil S-UE activity was the lowest,and the average value of soil S-ACP activity,the seedling rate of Atractylodes macrocephala,the content of leaching substance and yield were the highest.The yield increased by 361.33% compared with A1 B1 treatment.In summary,adding quicklime(300 kg/ha) and humic acid granule fertilizer(300 kg/ha) in the soil of continuous planting of Atractylodes macrocephala for one year can effectively regulate the soil enzyme activity,reduce the incidence of disease of Atractylodes macrocephala,and improve the seedling rate,quality and yield of Atractylodes macrocephala.
