Five kinds of bacteria were isolated from disease Meretrix meretrix and culture water (two isolated from the M. meretrix, three from the culture water) in Lvsi harbor, Jiangsu province. The results of infection showed that strain WG1702 can cause disease with the mortality rate 100 percent and the same symptoms as original. It was cued that strain WG1702 was the pathogenic bacteria and caused the death in large scare, a preliminary research was done on the bacteria including morphological, physiological, biochemical characteristics, phylogenetic position and pathogenic. Strain WG1702 was a straight-rod gram negative bacterium, the physiological and biochemical indicators were lysine decarboxylase, ornithine decarboxylase, reduction of NO3- to NO2-, mannitose, oxidase and methylred reaction positive, arginine decarboxylase, arginine dihydrolase, salicin and voges-proskauer negative.

本文从江苏吕泗文蛤养殖区发病文蛤和养殖水体中分离到5株优势菌(病蛤中分离到3株优势菌，养殖水体中分离到2株优势菌)，人工感染实验结果显示，菌株WG1702能引起供试文蛤发病，死亡率为100%，且发病症状与原发病症状相同，提示该菌是引起文蛤大面积死亡的主要致病菌，对其形态、生理生化特征、分类地位及致病性进行了初步研究，菌株WG1702为革兰氏阴性菌，直杆状，生理生化指标为：赖氨酸脱羧酶、鸟氨酸脱羧酶、硝酸盐还原、甘露糖、氧化酶、甲基红阳性，精氨酸脱羧酶、精氨酸双水解酶、水杨素、V.P阴性。

A new method of disease area mensuration and the percentage of diseases area of tea leaves with computer has been established by using Photoshop software to scan many leaves at the same time, and the further investigation also has been fulfilled. The results showed that when scanned with resolution 150 dpi,there were be short time to scanning and less disk space beenoccupied, and the effect as same as scanned with high -resolution. The results of disease area mensuration and percentage of diseases area of tea leaves using the new method also as same as the results using artificial mensuration, and the efficiency of the new method is much higher than the efficiency of artificial method.

摘 要：建立了通过对茶树叶片进行扫描，利用Photoshop软件同时获得多张叶片及其受害部位的像素值，从而快速计算茶树叶片受害面积以及受害面积百分率的测定方法，并对此方法进行了系统的研究，结果表明：扫描分辨率为150dpi时，扫描时间和存储占用空间较优，测定效果和高分辨率扫描效果基本一致，该方法测定结果与人工测定结果无显著差异，其效率远远高于人工测定。
