Disclosed herein is an indoor leaf multiplication method for aquatic plants, which is applicable in aquatic plants capable of reproducing leaves. The method includes cutting the petioles of aquatic plants off first to separate the leaves from the parental body, and then placing the leaves in the sink in which the water temperature is maintained at above 23 DEG C. Light is provided to irradiate the plant leaves in the sink. By cutting off the petioles of aquatic plants and controlling the water temperature and providing light illumination, the cut-off leaves can be subjected to the photosynthesis for producing nutrients, so as to grow bud recruits in the leaves. In this way, aquatic plants can be reproduced with simple equipments without being limited by the external climate conditions. Under the controlled environmental condition, the present invention can improve the survival rate of recruits and shorten the recruits cultivation time, thus having better reproductive efficiency and economic benefits.一種具有葉片繁殖能力之水生植物的室內葉片繁殖法,適用於具葉片繁殖能力的水生植物,該繁殖法為先切斷水生植物植株的葉柄,使其葉片與母體分離,再將該葉片放置於水槽,並使該水槽的水溫維持在23℃以上。再提供光線照射水槽中的植物葉片。藉由切斷水生植物的葉柄,並控制水溫與提供光線照明,就能促使被切離的葉片進行光合作用產生養份,進而在其葉片長出幼芽苗株。藉此,能以簡易設備在不受限於外界氣候的條件下進行水生植物繁殖。在控制環境條件下,能提高苗株存活率及縮短苗株培育時間,使本發明具有較佳的繁殖效率與經濟效益。
