引起郁金香产生盲花的因素分析

Analysis on the Causes of Tulip Blind Blooms

盲花的产生是郁金香 (TulipagesnerianaL)发生退化的重要标志。郁金香种球贮存期间温度处理不当 ,会使种球在花芽分化后花芽的正常发育受到影响 ,这是郁金香产生盲花的主要原因 ;种球连续多年栽培 ,盲花率随栽培年分大幅上升 ,原因可能是种球病毒逐年积累所致 ;栽培温度过高主要影响郁金香切花质量 ,对郁金香盲花的形成也有影响 ;种球大小与盲花无关。创造适合郁金香正常生长的栽培环境 ,尽量延长生长期 ,可提高郁金香切花品质及产生新球的数量和质量。

The emergence of blind blooms is an important sign of tulip retrogression.One of the main reasons for tulip blind blooms is that inappopriate storage temperature of tulip seed bulbs affects the normal development of flower buds after the differentiation of flower buds.Another reason for tulip blind blooms is that years of continuous cultivation of seed bulbs results in the accumulation of viruses in bulbs.During the cultivation of tulip,if temperature is high,the quality of cut flowers may be affected,and tulip blind blooms may be induced.The size of seed bulbs has nothing to do with the formation of blind blooms. By providing appropriate cultivation and by prolonging the vegetative period to the greatest extent,the quality of cut flowers can be improved,and the number of new seed bulbs can be increased.
