东方百合露地越冬覆盖材料筛选试验

Selection of Covering Materials for Overwintering of Oriental Lilies in the Open Field

以东方百合品种"索邦"(‘Sorbonne’)、"西伯利亚"(‘Siberia’)和"提伯"(‘Tiber’)为试材,采用测定6种覆盖材料下表土日均温、定时日积温和总积温的方法,对露地越冬球产花性状指标与窖藏球进行对比,研究了不同覆盖材料对东方百合露地越冬的影响。结果表明:草帘+塑料薄膜是实现东方百合种球露地安全越冬的覆盖材料,为东北地区东方百合种球露地越冬栽培提供依据。

The three oriental hybrid lily cultivated varieties were used as experimental materials.The topsoil daily mean temperatures,timing accumulated temperatures and total accumulated temperatures under six covering materials were surveyed,and the flowering character index between overwintering bulb and cellar storage bulb were contrasted.The effect of different covering materials to overwinter safely for oriental hybrid lily was studied.The results showed that the straw＋plastic film was the best covering material for safe overwintering.It provided a scientific basis of overwinter safely for oriental hybrid lily in Northeast China.
