Rhododendron seed propagation method

Abstract

The invention discloses a rhododendron seed propagation method. The rhododendron seed propagation method includes following steps of (1) soil disinfection; (2) seedbed selection and preparation; (3) seed selection and processing; (4) seeding; (5) seedling management which includes fertilization, weeding, scarification and pest prevention and curing. The rhododendron seed propagation method performs bud forcing treatment on seeds 10d before the seeding, uses 0.5% potassium permanganate liquid to disinfect the seeds, covers the seeds with a film in bud forcing, and achieves short seedling emergence time, uniform seedling emergence and quick growth speed.
