CULTIVATION METHOD OF ASPARAGUS

To solve problems that a method for moving only a root part of asparagus into a greenhouse in winter season and planting the part in the greenhouse as a method for causing seasonal sensory illusion in asparagus can only be performed in a cold district, or necessary additional fertilization cannot be performed in a dormant period because of a perennial plant.SOLUTION: A method comprises: light shielding means for shielding light to asparagus; and cooling/heating means for cooling/heating a root part of asparagus, where seasonal sensory illusion is caused in asparagus to delay growth and harvest time of asparagus, seasonal sensory illusion is caused in asparagus without transplanting or despite a cold district, and growth and harvest time are delayed to make it possible to harvest from late autumn to early winter.SELECTED DRAWING: Figure 2 【課題】 アスパラガスに季節の錯覚を起こさせる方法として、冬季に根の部分だけをビニールハウスへ移し、定植させる方法があるが、寒冷地でなければできない、また、多年草なため、休眠期に追肥の手入れが必要であるが手入れが行えない。【解決手段】 本発明は、アスパラガスへの光を遮光する遮光手段と、アスパラガスの根部を冷暖房する冷暖房手段とを具備し、アスパラガスに季節の錯覚を起こさせ、アスパラガスの成長および収穫時期を遅らせ、移植することなく、また、寒冷地でなくてもアスパラガスに季節の錯覚を起こさせ、成長および収穫時期を遅らせ晩秋から初冬季にかけて収穫できるようにしようとするものである。【選択図】図２
