Seashore paspalum, also known as Hawaiian grass, is a plant of the genus Paspalum in the Poaceae family, native to tropical and subtropical coastal areas.
The stalks are very long, up to tens of centimeters long, with long pedicels and hairless nodes. It is extremely salt-tolerant, almost twice as salt-tolerant as Bermuda grass, with a salt tolerance concentration of 0.04%~0.06%, and can be irrigated with seawater.
It has strong adaptability to soil, and the suitable soil pH value is 3.5~10.2. It can grow well in sandy soil, loam, heavy clay, and silt, and is resistant to flooding.
Application of plant growth regulators on seashore paspalum:
- Promote rapid greening in spring
Use 30~50mg/L gibberellic acid solution to spray the plants on the leaves, and cooperate with water and fertilizer management, which can significantly accelerate the growth of lawn grass in the low temperature season in spring and promote the early greening of seaside paspalum lawns.
- Regulate growth and reduce manual pruning
In the hot summer season, the growth rate of seashore paspalum lawn is fast and the pruning frequency is high. Spraying the leaves of seashore paspalum with a mixture of 600mg/L DA-6 + 600mg/L Ethephon + 200mg/L Uniconazole can effectively slow down the growth rate of the lawn and reduce the pruning frequency.
