PROBLEM TO BE SOLVED: To provide a white asparagus-growing vessel which dissolves problems that growing asparagus is technically very difficult as it is cultured in invisible soil, wastes a firm and requires time and labor, as the white asparagus is conventionally cultured in soil with raising the soil to be high for shadowing and then harvested. SOLUTION: Shoots of asparagus in size ofϕ10 m/m-ϕ25 m/m come out of the soil. A means combiningϕ20 m/m-ϕ40 m/m VP pipes or VU pipes and weeding sheets excellent in shadowing and permeability is used. Therefore, both white and green asparagus are simply cultured in the same farm at the same time. COPYRIGHT: (C)2004,JPO
