摘要

The effects of high temperature treatment by non-ventilation of greenhouse on fruit yield and the incidence of diseases and insects in summer cucumber production were evaluated against constant ventilation (control). Fruit yield for 5 cultivars of summer cucumber was increased by setting the ventilation temperature at 45 degreesC from 4:30 until 10:30. Diseases and insects were effectively Suppressed by high temperature. Non-ventilation should be done during the lunch break during 11:30-13:20 in consideration of the worker's comfort. Most diseases and insects (except mites) could be controlled. However, with daily high-temperature treatment the number of dead or malformed fruits increased. Until the beginning of harvest, frequent non-ventilation treatment may exterminate diseases and insects and increase the number of fruiting nodes. Thereafter, frequency of the treatment should be reduced to ensure fruit set and growth.
