不同种植密度对睡莲切花品质的影响

Effect of Different Planting Density on Quality of Cut Flower of Nymphaea spp.

以睡莲品种"豪华"为试材,研究了不同种植密度对其叶片数量、开花数量、叶茎、根茎和花冠径的影响。结果表明:不同种植密度对睡莲品种"豪华"的叶片数量、开花数量、叶茎和根茎均有显著影响,但对花冠径影响不大;种植密度越大(处理A,20株/10m2),总叶片数量、开花数量、叶茎和根茎越少;处理B(10株/10m2)的叶片数量、开花数量、叶茎和根茎长均保持在合理的水平上;而与处理B相比,处理C(5株/10m2)叶片数量、开花数量、叶茎和根茎长均无显著差异。综上,处理B(10株/10m2)是睡莲切花栽培的合理种植密度。

Using Nymphaea ＇ Somptuosa＇ as material, the leaf number, flower number, leaf steams, roots, and the corolla diameter at the different planting density were investigated. The results showed that the different planting density on leaf number, flower number, leaf steams, and roots of all had significant impact, but little influence on corolla diameter. The greater the planting density （treatment A, 20 plants/10m2 ）, the less the leaf number, flower number, leaf steams, and roots. For treatment B（10 plants/10m2 ）,the leaf number,flower number,leaf steams,and roots were kept at a reasonable level,and when compared to C （5 plants/10m2 ） and B, the leaf number, flower number, leaf steams, and roots were no significant difference. In conclusion,treatment B（10 plants/10m2 ）was reasonable planting density of Nymphaea spp. cut flower cultivation.
