The Analysis Of Vegetable Greenhouse Growers' Willingness Under Greenhouse Disease In Economics Horizon

With the development of modern agriculture science and technology, vegetable greenhouse had already become the very important part of facility Agriculture. Greenhouse can plant vegetable throughout the year without seasons' impediment.
