Morphological characteristics Small shrubs, 1–2 meters high. Branchlets grayish brown, densely yellow-brown pubescent; stems erect, much branched. Leaves alternate, oblong to oblong-lanceolate or obovate-oblong, 3–5 cm long, 1.5–2.3 cm wide, apex slightly cuspidate, base cuneate, entire, slightly recurved, above except midvein Outer hairless, densely pubescent below. Flowers unisexual, monoecious or dioecious; apetalous, 2–5 clustered leafhoppers; sepals 6, 2 round, oblong, abaxially pubescent; male flowers with 3 stamens, non-degenerate ovary, female flowers ovary Being fuzz, usually 5-celled, styles shortly tube-shaped. Capsules pubescent, oblate, with prominent longitudinal furrows. Seed yellow red. Flowering from June to September. Fruiting period 7–10 months. Capsule flat spherical, diameter 12 ~ 16 mm, depression on the top, outside the longitudinal groove. Dried seeds contain about 20% oil. The roots of the plant (counting the roots of the plants) and the branches and leaves (counting the leaves of the plants) are also used for medicinal purposes. Ventilation is one of the most important components in a successful greenhouse.

If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
