Abstract

Abstract: Continuous cropping of Morchella will bring continuous cropping obstacles, resulting in a decline in the yield of Morchella and economic efficiency. On the plot of two years of continuous cropping of Morchella, the treatment group was planted with Morchella after planting a crop of rice by paddy-upland rotation, and the control group was planted with Morchella after planting a crop of watermelon by dry land rotation. By comparing the changes of soil physical and chemical properties, the growth indexes and diseases of Morchella, the effects of paddy-upland rotation on morel in continuous cropping fields were explained. The results showed that paddy-upland rotation could alleviate the continuous cropping obstacle of Morchella, which was mainly reflected in the fact that paddy-upland rotation could repair the soil environment for the growth of Morchella to a certain extent, shorten the growth cycle of Morchella, improve the stress resistance of Morchella, and at the same time reduce the occurrence of morel disease.

Key words: Morchella esculenta L., continuous cropping, soil, resistance, disease
