水仙开花报春,是不可多得的花中珍品。然而,在水培过程中,常常花葶夭折,花蕾枯萎或花蕾未开先衰,出现哑花。水仙出现哑花,一是鳞茎较小,花芽发育不良或还没形成花芽。有的鳞茎大小尚可,但在大田栽培时受到病虫危害,产生根腐、根早衰、叶早枯。这类鳞茎外观上不饱满,根盘干朽,根眼少,俗称“漏底花头”,水培后发根少,植株瘦弱,花葶低矮或花朵变小。
Narcissus flowering primrose, is a rare flower treasures. However, during the hydroponics process, flowers often bloom, flower buds wither or flower buds are not decapitated, and dull flowers appear. Daffodils appear dull flowers, first bulbs smaller, poorly developed flower buds or flower buds have not yet formed. Some bulb size is acceptable, but in the field cultivation by pests and diseases hazards, root rot, root premature aging, leaves early dry. Such bulbs appearance is not full, the root disk dry, root less, commonly known as “missing the end of the flower head”, hydroponics less hair roots, thin plants, scape lower flower or smaller.
