Greenhouse ventilation management: Spring graded ventilation should pay more attention. After the morning opened the shed one hour, open the vent 3-5 cm put a small wind, the purpose is to shed moisture to escape, adding carbon dioxide greenhouse vegetable greenhouses single quotes, for the smooth conduct photosynthesis supplementary materials. Isochronous Pengwen rose to above 28 ℃, will gradually leaked mouth open, keeping the greenhouse temperature does not exceed 33 ℃ (for cucumber, gourd and other vegetables for thermophilic) either. Translucent greenhouse: greenhouse vegetable greenhouses are single building lighting, which is a basic indicator light transmittance evaluate greenhouse light transmission properties. Transmission rate is the percentage of the amount of light penetration into the greenhouse and outdoor illumination volume. Greenhouse transmittance by translucent covering greenhouse affect material properties and light transmission rate of greenhouse skeleton shadow, and with different angles of solar radiation in different seasons, the transmittance of the greenhouse are subject to change.
