Abstract
[Objective] The aim was to screen the optimum seedling substrate for Stromanthe sanguinea.[Method] With S.sanguinea as tested material, corn stalk, peat and garden soil as seedling substrates, the physical and chemical indexes of S.sanguinea seedlings on each kind of straw seedling substrates were studied.[Result] The bulk density and total porosity of seedling substrate prepared by corn stalk with different proportions and garden soil were decreased with the decomposition of corn stalk and growth of crop.The nitrogen, phosphor and potassium content in substrate showed downtrend basically.Among them, the descending speed of each element in treatment with corn stalk-garden soil ratio being 3 to 7 was faster and under the treatment, the seedlings adapted the growth environment gradually, and had strong growth vigor and better development in the substrate through observing the exterior growth vigor of S.sanguinea seedlings.[Conclusion] The substrate with corn stalk-garden soil ratio being 3 to 7 was better seedling substrate for S.sanguinea.关键词
