Causes and Control Measures of Field Wilting of Watermelon and Melon
At present,the field wilting phenomenon of watermelon and melon is serious.The reasons of wilting of watermelon and melon are complicated,mainly caused by physiological factors and diseases and pests.In order to alleviate the field wilting of watermelon and melon during production,the causes and occurrence rules of field wilting of watermelon and melon were summarized from five aspects of physical acute wilting,fungal wilting,bacterial wilting,root-knot nematode and underground pests.Then,five control measures were put forward,including breeding and spreading resistant varieties,managing soil scientifically,breeding seedlings scientifically,strengthening field management,strengthening plant quarantine and improving field diagnosis ability.In the future,it is necessary to coordinate the varieties,cultivation and plant protection of watermelon and melon.The collection and innovation of resistance germplasm resources in watermelon and melon will be strengthened to breed multi resistant varieties by fully taping and utilizing wild watermelon and melon resources and extracting resistance genes from them through genetic engineering.Promoting grafting cultivations which take the grafting rootstocks for watermelon and melon that are highly resistant to various diseases and pests and have no adverse effects on fruit quality as the core of future grafting and reproduction work.The establishment of a rapid detection technology system for pathogens will be accelerated to reserch on rapid detection methods such as pathogen detection,disease and pests rapid diagnosis kits,which can improve the accuracy of pathogen diagnosis of watermelon in the field.
