| Abstract: To improve the strong seedling rate of strawberry virus-free seedling in the stage of domestication and transplanting, grass carbon, vermiculite and perlite were used as seedling substrates with the conventional substrate as the control (CK, grass carbon∶vermiculite∶perlite = 2∶1∶1), the effects of different substrate ratios on the growth of strawberry seedlings were studied to screen out suitable cultivation substrate. The results showed that the different substrate ratios had obvious effects on the strawberry seedlings in domestication and transplanting stage. The substrate formula D (grasscarbon∶vermiculite=2∶1) had the best effect on the plant height, stem diameter, leaf area, above ground and underground biomass, root total length, root surface area, root volume and seedling index of strawberry seedlings. It was suitable for strawberry seedlings domestication and transplanting, and prefer able to cultivate robust seedling. The substrate formula A (Dachang seedling substrate: vermiculite∶pearlite=1∶1 ∶1) was better than the control in the upper part of strawberry seedling, and the cost of per cubic meter was 14.18% lower than that of CK with 50 yuan less. It was suggested that the above two substrate formulas should be popularized and applied. |
