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： The present invention provides a film for packaging chemical agents, which contains an oxyalkylene unit-containing polyvinyl alcohol resin (A) and a carboxyl-containing polyvinyl alcohol resin (B), and preferably further containing a sulfo-containing polyvinyl alcohol resin (C). This film shows fine solubility in water even after a long-term packaging of an acidic chemical agent or alkaline chemical agent, and is superior in mechanical strength. Thus, the film for packaging chemical agents of the present invention is suitably used for packaging a chemical agent, such as powdered soap, synthetic detergent, agricultural chemical, antibacterial, deodorant, insecticide and the like, which is cast into water when in use.
