冬枣贮期主要病害及防治技术的研究

Studies on Prevention and Cure Methods for Main Diseases in Storage of “Dongzao”Jujube

本文对冬枣贮期主要病害种类、危害特点和防治技术进行了系统研究;通过对冬枣贮期危害最为严重的病害病原菌的分离、培养和回接试验,对冬枣浆胞病进行了定性研究;同时研究了不同温度对冬枣浆胞病病原菌生长的影响。并在此基础上,对冬枣贮期主要病害进行了防治技术研究,选出了最佳防治药剂和使用浓度。

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.
