瓜叶菊(Cineraria cruenta Mass)是重要的温室盆花之一,其生长适温为15～20℃,苗期不耐高温,因此,在江浙地区瓜叶菊的安全播种期为8月中下旬,其自然开花期3～5月,形成瓜叶菊开花上市集中,经济效益低。为了克服平原夏季高温对瓜叶菊播种期的限制,本试验利用高山夏季凉爽的气候条件,于7月下旬在高山播种,约在11月上旬将瓜叶菊盆栽苗运回本所(杭州钱塘江畔)塑料大棚内继续培育,可以促使瓜叶菊在元旦、春节期间开花。
Cineraria cruenta Mass is one of the most important greenhouse potted plants. Its suitable temperature for growth is 15-20 ℃ and its seedling is not tolerant to high temperature. Therefore, the safe planting period of cineraria in Jiangsu and Zhejiang is mid to late August. Flowering from March to May, the formation of cineraria flowering market concentration, low economic benefits. In order to overcome the plains summer high temperature on the cineraria seeding period limits, the use of alpine summer cool climatic conditions, in late July sown in the mountains, about early November will be returned to the cineraria plant seedlings (Hangzhou Qiantang River ) Plastic greenhouse to continue nurturing, can promote cineraria during New Year’s Day, during the Spring Festival flowering.
