Irrigation and Easter lilies E

摘要

Easter lilies are usually watered on demand using either overhead or subirrigation. During the winter months, when plants are _ small and evapo-transpiration is low, the irrigation strategy may be questioned. One of the common questions is whether towater small amounts often or large amounts less frequently.With this question in mind, we started an experiment during the fall of 2009 to determine whether there is an effect from irrigation frequency.
