Abstract
Substrate is gradually being used in strawberry (Fragaria × ananassa Duch.) seedling cultivation to reduce pathogen infection in seedlings and improve efficiency.
To determine the effect of substrate composition on strawberry seedling cultivation, the growth of strawberry mother plants and seedling emergence were evaluated using six commercial substrates.
The results show that T2 (20% peat + 40% coir + 20% perlite + 20% wood fiber) and T3 (50% peat + 15% perlite + 35% well-rotted manure) have advantages in terms of strawberry mother plant growth and seedling emergence rate.
Peat improves the aeration porosity, total porosity, and water-holding capacity of the substrate.
The addition of well-rotted manure also enhances the aeration porosity and water-holding capacity, both of which positively affect strawberry growth.
However, fermented twigs show a negative correlation with water-holding capacity of the substrate.
The addition of fermented twigs promotes the accumulation of excess AN (ammonium nitrogen) and AK (available potassium) in the substrate, which may be detrimental to the growth of strawberries after planting.
Therefore, peat and well-rotted manure as organic components in the substrate are more conducive to the growth of strawberry seedlings.
The nutrient storage capacity and microbial structure of different substrates are also critical for strawberry growth.
These results suggest that a suitable substrate for strawberry seedling cultivation requires a comprehensive evaluation of the physical, chemical, and biological properties of the components.
