快速事实
植物特征
Robust, creeping perennial legume with good shade tolerance. Produces persistent ground cover even under established plantation canopies. Deep-rooting system contributes to subsoil nutrition and aggregate stability.
USES
Nitrogen fixation under shade, erosion control, soil cover in cacao and agroforestry systems, and establishment for replanting and slope protection. Centrosema pubescens sustains biological nitrogen fixation at 120–270 kg N/ha/year even under canopy shade up to 80% — making it a strong choice where other cover crops struggle beneath closed cacao or rubber canopies. Tissue nitrogen remains stable at 2.4–2.7%, maintaining continuous fertility contribution through leaf turnover.
GROWTH HABIT
Achieves dense ground cover within 4–8 months under adequate rainfall. Requires good conditions during establishment but produces persistent, self-maintaining cover once rooted. Suitable for slope gradients where erosion risk is high.
PLANTING TYPE & SEEDING RATE
Monoculture or mixture: 2–4 kg/ha
PLANTING METHOD
Direct sowing — broadcast or rows
DRY MATTER PRODUCTION
5–9 t/ha/year
NO. OF SEEDS/KG
~65,000 seeds
