Production Technology of Alstroemeria
This document provides information on the production technology of Alstroemeria, commonly known as the Peruvian lily or Inca lily. It discusses the species, varieties, climate and soil requirements, propagation methods, cultivation practices like planting, irrigation, and pest and disease management. The key points are that Alstroemeria is native to South America, grows well in cool sub-tropical climates, and its straight stems that last 2-3 weeks in water make it a popular cut flower for bouquets and arrangements.
