Planting
In polyhouse, mainly cucumber is cultivated by
transplanting. However, directly seeding in bed is implemented for early autumn
or late summer planting, when the temperature is generally high for good
germination of seeds. Cucumber cultivation is successfully possible, if
transplantation is done properly. The root system of young seedlings may be
damaged and growth is restricted if soil temperature is low. On the other hand,
overgrown or aged seedlings do not establish in soil. Cucumber seedlings should
be placed deeply in soil and irrigated immediately for stand establishment.
Irrigation water helps plant to protect from fluctuation of temperature during
day and night.
