AbstractThe manifestations and mechanisms of continuous croppng obstacles in ornamental gourds，with fruit morphology and cortexqualityas the core values were systematicallyreviewed，and integrated control measures for cucurbit crops were proposed.The obstacle of continuous cropping of ornamental gourds refers to the growth inhibition phenomenon that occurs aftercontinuous cultivationof the crop，which not only manifestsas slow sedling growth， abnormalroot development，decreased plant resistance，and high incidence of pests and diseases，but also directlyleads to problems such as fruit deformityand rough cortex.The mechanisms primarily involve：imbalanceof soil nutrients due to excessive fertilizer application，leading tomicronutrient deficiencyand salt accumulation;buildupof soil-borne pathogens and pests （Fusarium spp.and root-knot nematodes）;and the accumulation of phenolic acids released through root exudates and residue decomposition.Basedonthis，acomprehensive prevention and control strategy for continuous croppingobstacles of cucurbit crops was summarized，with the premise of ensuring thecommercializationof the crop， includingsoil management，regulatingsoil nutrition throughbalancedfertilization，increasedorganic fertilizer application，andsupplementationof secondaryand micronutrients，while utilizing plant growth-promoting rhizobacteria to improve the microecology.Pathogen control，implementing croprotationmodelsto disrupt pathogen cycles，combined with physical and chemical methods suchas solarizationand chemical disinfection to reduce soil pathogen load. Beneficial microorganisms should bereintroduced after disinfection torestore soilfertility.Biotechnology appications， breeding disease-resistant varieties and using grafting techniques （with pumpkin rootstocks）to enhance plant stress tolerance.These measures colectively form an integrated management system，providing a reference for addressing continuous cropping obstacles in ornamental gourds.
