Made in the shade:Low-cost protection of valuable space is made possible with shadehouses

摘要

Excessive solar energy and wind can wreak havoc on greenhouse inventory if not protected sufficiently. When solar energy is converted to heat energy, it strikes plant leaves, resulting in excessive air, leaf, and soil temperatures. Placing plants under a 30 to 50 percent shade in the middle of the summer can lower leaf temperature by 10°F or more. This along with reduced wind speeds can significantly lower transpiration water losses during the growing season.
