<P>PROBLEM TO BE SOLVED: To provide a growth promotion method of a plant that can reduce a cultivation cost, and can accelerate the growth of a plant. <P>SOLUTION: The growth promotion method of a plant is characterized as follows. Seeds of a plant are sowed, the exposure to NO<SB POS="POST">2</SB>is begun within 14 days at latest after the seeding, is stopped by seven days before the harvesting at latest. In addition, the period of exposure to NO<SB POS="POST">2</SB>is continued at least seven days and at most 28 days. The exposure to NO<SB POS="POST">2</SB>is performed only for an early period after seeding, thereby a growth cost can be reduced. Moreover, the exposure to NO<SB POS="POST">2</SB>is performed at a beginning stage of the growth of a plant, thereby the growth of a plant after that can be promoted, and thereby the equivalent growth with the growth of a plant always under an atmosphere of NO<SB POS="POST">2</SB>after the seeding can be promoted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
