PROBLEM TO BE SOLVED: To provide a method for growing plants using a water-absorptive sheet having water-retaining and water-supplying ability for growing a lot of plants, and easily improving the water-retaining properties of soil without troublesome operation such as mixing operation.SOLUTION: The method for growing plants using a water-absorptive sheet includes placing a water-absorptive sheet so that the water-permeable surface of the water-absorptive sheet at least one surface of which has water permeability and contains powder of the following water-absorptive resin, faces to the root side of each of the plants in the soil to be in contact with the soil. The water-absorptive resin: the electric conductivity ratio of the water-absorptive body when making 100 pts.wt. of ion exchange water at 25°C absorb 1 pts.wt. of water-absorptive resin is 0-2.0 mS/cm and the water-absorption magnification of the 25°C ion exchange water is 80-1,000 times.COPYRIGHT: (C)2010,JPO&INPIT【課題】 多くの植物を育生するための保水と給水能力を備え、混合するなどの面倒な作業をすることなく容易に土壌の保水性を向上させる方法を提供する。【解決手段】 少なくとも片面が透水性であって下記吸水性樹脂の粉末を含む吸水性シートの、該透水性面を土壌中の植物の根側に向け土壌に接して配置して植物を育生する方法。吸水性樹脂: 吸水性樹脂1重量部を25℃のイオン交換水100重量部に吸水させた時の吸水体の電気伝導率が0~2.0mS/cmであり、且つ25℃のイオン交換水の吸水倍率が80~1000倍である。【選択図】 図2
