    • A horticultural growing medium comprises a polyisocyanate-polyol-based polymer, and at least one filler material. A method of making a horticultural growing medium comprises the steps of mixing at least one filler material with a polyisocyanate-polyol-based quasi-prepolymer composition, to form a quasi-prepolymer/filler mixture and applying water to the quasi-prepolymer/filler mixture to form a hydrophilic growing medium. A method of growing plant seedlings comprising planting a seed or seedling in a horticultural growing medium containing a hydrophilic polyisocyanate-polyol-based polymer and at least one filler material, is also disclosed. A hydrophilic urethane polymer comprises the reaction product of a quasi-prepolymer and water wherein the quasi-prepolymer contains an isocyanate and a hydrophilic polyol. A method of making a hydrophilic polyurethane comprises the steps of adding a hydrophilic polyol to an isocyanate, mixing the polyol and isocyanate to form a quasi-prepolymer, and contacting the quasi-prepolymer with water.
    • 园艺培养基包括多异氰酸酯 - 多元醇基聚合物和至少一种填充材料。 一种制备园艺培养基的方法包括将至少一种填料与多异氰酸酯 - 多元醇基准预聚物组合物混合以形成准预聚物/填料混合物并将水施加到准预聚物/填料混合物 以形成亲水性生长培养基。 还公开了种植植物幼苗的方法,其包括将种子或幼苗种植在含有亲水性多异氰酸酯 - 多元醇基聚合物和至少一种填充材料的园艺培养基中。 亲水性聚氨酯聚合物包括准预聚物和水的反应产物,其中准预聚物含有异氰酸酯和亲水多元醇。 制备亲水性聚氨酯的方法包括以下步骤:向异氰酸酯中加入亲水多元醇,混合多元醇和异氰酸酯以形成准预聚物,并使准预聚物与水接触。
