Abstract: The main types, harming properties, and prevention & cure techniques for diseases in storage of "Dongzao" jujubewere studied systemically in the paper. The softening and decay disease ("Jiangbao" disease) was studied qualitatively byseparating, cultivating, and back-inoculating of the pathogenic bacteria whereas the damages were most serious in storage of"Dongzao" jujube.The effects on the development of pathogenic bacteria of softening and decay disease during storage at differenttemperatures were also studied.The optimum conditions of the prevention and cure techniques on main pathogenic bacteria instorage were studied and the medicament and dosage concentration were determined.

Key words: Dongzao", jujube, period of storage, disease, techniques of prevention and curing
