柔毛齿叶睡莲的繁殖及盆栽技术研究

以柔毛齿叶睡莲休眠茎为材料，分别采用水培法和泥栽法对其进行繁殖，并研究不同容器规格、施肥频率对其生长势的影响。结果表明，水培法可大幅度提高其繁殖系数，成苗数是泥栽法的5.2倍；盆栽容器规格、施肥频率对植株生长势具有显著影响，较大规格容器中植株生长势较好，不同处理的施肥频率均对植株生长具有促进作用。幼苗期宜选择15 cm口径大小的容器栽植，成年期宜选择30 cm以上容器；施肥频率以每30 d 1次为宜。

Propagation and Pot Cultivating Techniques of Nymphaea lotus var.pubescens

The dormant stems of Nymphaea lotus var.pubescens were chosen as the experimental materials.The plantlets were separately propagated with dormant stems in the water and mud to test propagation coefficient differences of different culture methods.The effects of different container sizes and fertilization frequencies to the growth potential were compared.The results showed that water could greatly improve the propagation coefficient,and plantlets number was 5.2 times more than that cultured in the mud.Container size and fertilization frequency had significant influences on plant growth potential and plant growth,and the growth of the plantlet was better in the container with large size.The fertilization in all the treatments could promote the plant growth.It was suggested that in the plantlet stage,the size of the container was 15 cm in diameter,and 30 cm or more for adult stage.Fertilizing once a month was recommended.
