We are facing global issues concerning environmental pollution and
shortages of food, feed, phytomass (plant biomass) and natural
resources, which will become more serious in the forthcoming
decades. To solve these issues, immeasurable numbers of various
plants and huge amounts of phytomass are required every year for
food, feed and for the improvement of amenities, the environment
and our quality of life. Increased phytomass is also required as
alternative raw material for producing bio-energy, biodegradable
plastics and many other plant-originated industrial products. Only
by using phytomass as a reproducible energy source and raw
material, instead of fossil fuels and atomic power, we can save
natural resources and minimize environmental pollution. To increase
phytomass globally, we need billions of quality transplants (small
plants) to be grown yearly, in the field or in the greenhouse,
under various environmental conditions. However, these high quality
transplants can be produced only under carefully controlled, rather
than variable environment al conditions. Recent research has shown
that the closed transplant production system requires considerably
small amounts of electricity, water, fertilizer, CO) and pesticide
to produce value-added transplants as scheduled with minimum
release of environmental pollutants and minimum loss of
transplants. The closed or closed-type transplant production system
is defined as a transplant production system covered with opaque
walls with minimized or controlled ventilation rates, using
artificial lighting. With this system, photoperiod, light intensity
and quality, air temperature, humidity, CO) concentration and air
current speed can be controlled as desired.
