摘要： [Problems] Prior art technology has a problem in that when a plant is cultivated for a long period of time on a polyvinyl alcohol (PVA) film having its lower surface positioned in contact with a nutrient fluid, plant roots that have formed penetrate through the film.[Means to solve the problems] A plant cultivation system wherein the PVA film has an equilibrium degree of swelling in the range of from 125 to 250% as measured in water at 30° C. and has a loss tangent (tan δ) in the range of from 0.005 to 0.2 as measured in an equilibrium swollen state in water at 30° C., and a method for cultivating a plant by using this plant cultivation system.[Industrial applicability] Plant cultivation can be performed for a long period of time while avoiding infection by bacteria and the like causative of plant diseases. Therefore, the present invention is useful in, e.g., agriculture and the manufacture of pharmaceuticals.
摘要翻译： 现有技术存在的问题在于，当将植物长时间培养在其下表面与营养液接触的聚乙烯醇（PVA）膜上时，已经形成的植物根部穿过 电影。 [解决问题的方法]一种植物栽培系统，其中在30℃下在水中测量的PVA膜具有在125至250％范围内的平衡膨胀度，并且在其中具有损耗角正切（tanδ） 在30℃的水中以平衡溶胀状态测定的0.005〜0.2的范围，以及使用该植物培养体系培养植物的方法。 [工业实用性]植物栽培可以长时间进行，同时避免细菌感染等引起植物病害的发生。 因此，本发明在例如农业和药物的制造中是有用的。
