Mott dwarf elephant grass is suitable as forage for fish farming
Mott dwarf elephant grass is a grass-family forage introduced from the United States a few years ago. This grass is perennial, with a plant height of 0.8-1.4 m, short and numerous nodes, a large amount of leaves per plant, and strong tillering and regrowth ability. It is relatively cold-tolerant; in winter the aboveground part turns yellow and withers, while the underground part survives. It sprouts in spring and begins to grow when the temperature is around 12°C. It prefers to grow in places with deep, fertile and moist soil.
This forage is high-yielding and highly nutritious. Under good water and fertilizer conditions, it can produce 15,000-20,000 kg of fresh grass per mu, and its leaf amount accounts for more than 80% of the total grass amount. The hay contains 12%-14% crude protein and has good palatability. If managed well, newly planted grass can begin to be cut for green use after 45-55 days, and thereafter it can be harvested about once every 15-20 days. For the first cut, leave a stubble of 5-10 cm; for later harvests of regrowth grass, it can be cut level with the ground. It can be used continuously for 5-8 years.
