当今市场上,绝大部分春节催花的牡丹盆土都较笨重,花色品种少,规格单一,叶片小而稀,综合质量不能尽善尽美。俗话说:“好花还需绿叶配。”与自然生长的牡丹相比,春节催花牡丹叶片相对小而稀,原因大体有以下几个:一是牡丹具有花谢后叶片迅速增厚的特性,加之催花牡丹生产仅50天左右,生长期短,不待叶片完全放大,花蕾就率先开放投入市场了。因此,催花牡丹的生产期安排在60～70天较好。特别是当牡丹进入展叶期后,在平蕾和垂萼透色期,将温度掌握在下限,延长开花时间,对叶片的生长有明显的效果。二是催花技术虽有不断提高,但使用的仍是口授身教的传统方法,仍处于想尽一切办法提高成花率这样的水平上,对成花质量谈不上深入研究。至今没有催花数字化的依据和资料、催叶技术相对滞后。三是催花生产设备简陋,绝大多数生产场地是塑料大 In today’s market, the vast majority of peonies in the Spring Festival are more cumbersome, with fewer flower varieties, simple specifications, small and thin leaves, and the comprehensive quality can not be perfect. As the saying goes: “good flowers need green leaves with.” Compared with the natural growth of peonies, the Chinese New Year peony leaves relatively small and thin, for the following reasons: First, peony flowers with Xie rapid leaf thickening characteristics , Coupled with the promotion of peony production only 50 days or so, the growth period is short, not to be fully enlarged leaves, flower buds on the first open to the market. Therefore, the flowering of peony arrangements for 60 to 70 days is better. Especially when the peony into the leaf stage, in the smooth bud and calyx transparent period, the temperature at the lower limit, to extend the flowering time, the growth of leaves have a significant effect. The second is that although the technology of promoting flowers continues to improve, the traditional method of teaching is still used. It is still at the level of trying every means to increase the rate of flowering, so as not to mention further studies on the quality of flowers. So far there is no basis for the digital and reminder flower data, leaves technology is relatively lagging behind. Third, reminder flower production equipment is simple, the vast majority of production sites are large plastic
