| 摘 要： | 越冬覆盖可减少冬季土壤水分的损耗,在地膜和秸秆覆盖中,以地膜覆盖保墒最好;覆盖物的不同,春季地温回升快慢不同,各处理间黄花菜生育期以地膜覆盖出现较早,秸秆覆盖出现较迟;同一时期测定的黄花菜叶长和叶宽,以地膜覆盖长势较好,秸秆覆盖长势最差。同时地膜覆盖抽薹数和落蕾数比对照多,秸秆覆盖抽薹数比对照多,而落蕾数比对照少,从而使秸秆覆盖产量比对照增产27.3%～165.9%;地膜覆盖产量因受干旱和冰雹灾害的影响不同,产量与对照比有增有减,在试验地两年里,2004年因干旱影响严重,产量比对照减产4.9%,2005年虽有干旱影响,但在春苗期,主要是受5月30日冰雹的影响,使产量比对照仅增产7.9%。黄花菜日鲜重与采摘天数呈现二次型曲线变化。 |

| Abstract: | Cover treatments through the winter period can reduce the loss of soil moisture;hence the effect of plastic film and straw covers were investigated on the soil planted with lily flower.It was found that the cover treatment with plastic film was better than straw in terms of holding soil moisture and reducing the loss of soil water.Also the increase in temperature was different between the two treatments.Moreover,cover treatments could increase the yield of lily flower. |
| Keywords: | Water loss through winter Cover treatment Lily flower |
