Take fuzzy comprehensive evaluation method in the study of 20 large flower rose varieties, screening, selection suitable for potted flower rose varieties, lay the groundwork for the facilities potted flower Rose planting. Culture substrate choice the potted flower Rose soilless growing media, filter out the potted flower Rose matrix suited to do to prepare for the production of potted flower Rose facilities. Forcing cultivation under greenhouse conditions, due to light and temperature limit, potted flower Rose often plant type is too high, there will be the phenomenon of lodging, flowers the slender and blades light green, thus affecting its ornamental effect. Pot production of flower Rose appropriate dwarfing treatment will help to improve their growth status and increase its ornamental value. Investigated the effects of solar greenhouse under the conditions of use of growth retardants PP333 processed and combined with water and fertilizer management Potted cultivation to provide theoretical and technical basis for a solar greenhouse planting potted flower Rose. 1, according to the potted flowers industry standards and Rose's ornamental characteristics, select plant height, plant type, flower rate, length of flowering 8 traits such as evaluation index, fuzzy comprehensive evaluation approach, the pot 20 flowers rose varieties comprehensive evaluation and rating classification results by rating, to elect suitable for large flower pot rose varieties. In 20 varieties, selected the seven most suitable for potted varieties, six more suitable for potted varieties, three varieties of potted plants can be considered and not suitable for the four varieties of potted plants. 2, the paper using peat, perlite, vermiculite and sand, and other raw materials are mixed in different proportions to form four kinds of new matrix, Potted cultivation experiment, as a comparative and the garden soil cultivation, filter suitable for potted flowers rose cultivation soilless matrix. Five kinds of physical and chemical properties of the formulation and the Potted growth characteristics were measured indicators and observation data were analyzed by ANOVA and multiple comparisons. Ultimately determine the optimal matrix formulation: peat: vermiculite: perlite = 1:1:1. 3 In this paper, the the growth retardants PP333 processing potted flower Rose 'Fei Fan', using a foliar spray and root watering 2 treatment, a total of five different mass concentration, the results showed that: foliar spray 1000mg.L-1 paclobutrazol best results, extend potted viewing period, increase the ornamental value. Spraying PP333 can increase chlorophyll content, quality improve flower Rose 'Fei fans' flowers heavy with flower diameter.
