In order to select suitable substrate formula for cultivating strawberry cuttage seedlings,this study used strawberry variety Momoiro hoppe No.8 as experimental material.Through measuring physical and chemical indices of sub-strates with different ratios and growth indices of strawberry cuttage seedlings,the effects of different substrates on the growth of strawberry cuttage seedlings were analyzed.The results showed that there were differences in total porosity,water-holding porosity and aeration porosity of different substrates,and different substrates had different effects on the growth of strawberry cuttage seedlings.The optimum substrate ratio was coconut bran∶peat∶perlite=4∶1∶1(weight ratio).The bulk density,total porosity and water-holding porosity of the optimum substrate were high.The strawberry cuttage seedlings cultivated with the optimum substrate had relatively larger petiole diameter,plant height,stem diameter,petiole length,leaf length and leaf width.The underground part of strawberry cuttage seedlings cultivated with the optimum substrate had higher fresh weight and dry weight.The stomatal conductance,intercellular CO2 concentration and transpiration rate of strawberry cuttage seedlings cultivated with the optimum substrate were high.The results of the study provided a reference for the substrate configuration of strawberry cuttage seedlings.
