| Abstract: | These experiments were to select the optimum formula of substrate for Betula platyphylla Suk.grown in container by means of automatically recirculating ebb & flow subirrigation systems. By analyzing and measuring the substrates' physicochemical characteristics and plant growth of B. platyphylla including plant height and mass, net photosynthesis and leaf chlorophyll contents, concentration of nutrient elements, also media's uptake of water and nutrition, the results indicate that treatment M 1 of mixed substrate, namely peatmoss 3 + perlite 3 + vermiculite 3 expressed the best effects of plant growth, net photosynthesis and nutrient element contents when seedlings of B. platyphylla were planted in it. |
