Research Progress on the Mechanisms and Models of the Rotation Cultivation in Chinese Traditional Medicinal Crops
With the increasing demand for Chinese traditional medicinal crops,the area cultivated artificially has also expanded.However,due to the limited land area in authentic production regions,severe continuous cropping obstacles have inevitably arisen.Crop rotation is one of the main measures to overcome or alleviate these obstacles in Chinese traditional medicinal crop cultivation.It can effectively improve the soil quality of the fields,suppress disease occurrence,enhance the yield and quality of medicinal crops,and reduce the conflict between grain and medicinal plant cultivation.Starting from issues like autotoxicity from allelochemicals,changes in soil physicochemical properties and soil microbiota,and soil nutrient imbalances,this paper analyzes the mechanisms by which crop rotation mitigates continuous cropping obstacles and summarizes the crop rotation models and characteristics with various Chinese traditional medicinal crops,aiming to provide references for implementing reasonable crop rotation in Chinese traditional medicinal crop cultivation.
