PROBLEM TO BE SOLVED: To provide a plant cultivation greenhouse capable of decreasing agricultural noxious insect intrusion in the plant cultivation greenhouse having a ventilating fan, and having agricultural noxious insect intrusion preventing function. SOLUTION: This noxious insect intrusion preventing greenhouse for plant cultivation is such that the inside of the greenhouse is positively pressured to atmospheric pressure of the outside of the greenhouse by adjusting gas volume through driving one or a plurality of air intake ventilating fans (i) which are set on a boundary part between the greenhouse and the outside thereof, or alternatively, atmospheric pressure in the greenhouse is put together and positively pressured to atmospheric pressure of the outside by adjusting gas volume balance through simultaneously driving a plurality of the air intake ventilating fans (i) and exhaust ventilating fans (e). A temperature in the greenhouse is kept almost the same as that of the outside by performing ventilation in the greenhouse. COPYRIGHT: (C)2008,JPO&INPIT
