Abstract
To investigate the effects of tobacco garlic crop rotation and tobacco garlic crop intercropping on soil agrochemical characters and tobacco yield. In tobacco different mature stage,soil samples and tobacco yield were collected at tobacco monoculture,tobacco garlic crop rotation and intercropping system. And analysis of the results.Results indicate that the soil p H in rhizosphere increased in different system,with the growing of tobacco. In addition the soil p H in non-rhizosphere and rhizosphere of tobacco garlic crop rotation and intercropping system were higher than that of tobacco monoculture treatment. The organic content in tobacco rhizosphere and non-rhizosphere soils with the tobacco garlic crop rotation and intercropping treatment were higher than that of tobacco monoculture at mature stage of upper leaf. Moreover,the available nitrogen content in tobacco non-rhizosphere soil with the tobacco garlic crop rotation and intercropping treatment were significantly higher than that of tobacco monoculture treatment at mature stage of lower and upper leaf. The available phosphorus and potassium content in tobacco rhizosphere soil with the tobacco garlic crop rotation and intercropping treatment were also higher than that of tobacco monoculture treatment at mature stage of upper leaf. And furthermore,the tobacco yield and ratio of the middle class and superior leaves of tobacco garlic crop rotation and intercropping treatment increased by 35. 04 and 17. 55 percentage points,5. 88 and 3. 88 percentage points compared to the tobacco monoculture treatment,respectively. To sum up,the system of tobacco garlic crop rotation and intercropping can help mitigate the tobacco soil sickness,improve the soil microbial eco-environment and raise the yield of tobacco. Exploring the effects of tobacco garlic crop rotation and intercropping system on soil agrochemical characters and tobacco yield,which would provide a theoretical basis and technical support for improving tobacco soil,alleviating continuous cropping obstacle and creating a new cultivating system.
