environmental protection, economic efficiency and simplicity. It has outstanding
advantages and is of great significance for cultivating strong seedlings. Studies have
reported that light environment regulation has a significant impact on the growth and
development of cucumber, tomato, sweet pepper, rapeseed and other seedlings. In
addition, the gender performance of melons is susceptible to environmental factors
and chemical regulation. Since the sex differentiation of melons occurs in the seedling
stage, the gender performance of melons can be artificially controlled during the
seedling period by controlling the light irradiation. LED has unparalleled superiority
in the application of light environment regulation in vegetable seedling stage, and
will play an important role in vegetable plantation.
11.4.3 Lighting Design Features
According to the light quality required by specific plant, the design of the luminaire
and the artificial light supplement in the greenhouse have three main elements such as
light quality, light intensity and photoperiod. The light intensity, i.e. the illuminance
requirement, is based on the daylight compensation point of the main crop. The
