This paper introduced the advantages of planting sprout vegetables in family rooms,expounded assembly principle of indoor cultivating device and the key techniques for indoor cultivating sprout vegetables in families.In the experiment,we assembled a set of indoor cultivating device for sprout vegetables,and summarized the indoor cultivating techniques of sprout vegetables in families.The indoor planting device was suitable for family members to cultivate sprout vegetables in the living rooms,kitchen,balcony and other corner space by using their spare time.It could not only provide high-quality vegetables for families,but also beautify the indoor environments of family rooms,and increase the oxygen content in rooms.This set of indoor cultivating device and techniques was suitable for planting various sprout vegetables(e.g.radish seedling,water spinach seedling,pea seedling,pine willow seedling,sunflower seedling and various bean seedlings,etc.).This is a set of high-efficient spatial planting technique in families,and also an effective way to increase organic vegetable supply for family. 展开更多
