广州亚运会运动场草坪建植质量调查与分析

对广州亚运会运动场草坪的坪床结构、建植水平、养护管理技术及草坪状况进行调查研究,系统客观地评价各个运动场草坪质量。调查发现,运动场草坪的基础坪床结构对运动场的使用质量有直接的影响,草坪的建植和养护水平与草坪状况和草坪质量有密切关系,草坪的养护管理水平比草坪建植水平对草坪状况有更大的影响;广州天然运动场草坪在草坪建植和养护管理方面的投入不够,如果加强和提高建植草坪的技术方法和措施,运动场草坪质量将会有很大的提高空间。此次研究结果能较全面和准确的反映运动场草坪使用质量,与实际情况相吻合。

Heartworm in dogs in Canada in 1983

In late December 1983, 2 800 veterinarians across Canada were sent a questionnaire in order to assess the status of heartworm disease in Canada in 1983 and 26% of them responded.

Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario.

Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada. Southwestern Ontario continues to be the focus of the infection and most of the dogs there had not left the province previously.
