WATER-HOLDING CARRIERS FOR PLANTS AND WATER-HOLDING MATERIALS FOR GROWING PLANTS
摘要
A water-retaining support for plants comprising a hydrogel-forming polymer (A) having a calcium ion absorption of 0-100 mg per 1 g of the dry weight thereof, having a chlorine ion content of 0.07-7 mmol per 1 g of the dry weight thereof and having a water absorption magnification in ion-exchange water at 25 DEG C of 1.0 x 10<1> to 1.0 x 10<3>; or a plant body-growing water-retaining material comprising a molded product of a mixture of such a polymer (A) and a plant body-growing support (B). The water-retaining support for plants and the plant body-growing water-retaining material are those which have an excellent water-retaining property and they substantially do not cause inhibition of root generation or inhibition of root elongation.
