PROBLEM TO BE SOLVED: To provide a method for facilitating vegetation growth in which the uptake of water and specific nutrients into plants can be artificially managed or adjusted so that their growth can be facilitated.SOLUTION: There provided is a method for facilitating vegetation growth in which plants, water and specific substances are affected from one or more directions by a periodically fluctuating magnetic field, and the affecting AC magnetic field whose frequency is between 0.01 and 300 Hz, intersects with a DC magnetic field with 100 &mu；T or less.【課題】 植物の成長を促進し又、水、特定栄養物質の植物内部への取り込みを人為的に調節できる植物の促進方法を提供する。【解決手段】植物、水、特定物質に周期的な変動磁場を１方向以上から作用させる方法であって、その作用させる交流磁界の周波数は０．０１Ｈｚ～３００Ｈｚと１００μＴ以下の直流磁界を交差させることを特徴とした植物の成長促方法。【選択図】 図２
