Studies On Soilless Culture Of Chrysanthemum

The chrysanthemum (Dendranthema X grandiflora ) is the perennial herbaceous flowers. It originated in our country and now has become one of the ten famous flowers of China. There are many extremely famous and precious cultivars in China. At present, these cultivars are propagated by traditional cultivation techniques. These techniques that only caused low outputs are complicated to be operated and not suitable for the large-scale production. We are unable to get aseptic propergation and cannot make the products going abroad. So traditional way has no longer fit modern flowers demand. Chrysanthemum industrialization need soilless culture.The substrate and nutrient solution are the two important links in soilless culture. The soilless culture experiments of 'taizhenhanxiao' 'Ivkongque' 'qianshouguanyin' 'huanglongzhua' and 'shenma' 'helanfen' 'helanhuang' and so on were carried out with substrate and nutrient solution experiments. Plant height, stem thickness, florescence and period of flowering of chrysanthemum were analysised by using field test design and mathematics analyse. Results indicate that there are obvious differences among the treatments. The mixed substrate vermiculite + perlite 4- peatl: 1: 1 and peat + perlite 1: 1 expressed the best effects. And the chrysanthemum need sufficient nitrogen in growth period of nutrition, after entering reproduction growth period, it should reduce the content of nitrogen element in the nutrient solution.The paper comprehensivly analyses the substrate and nutrient solution in soilless culture of chrysanthemum and thus provides useful data for industrialization of cultivated chrysanthemum.
