繁殖扶桑用常规的扦插法一般成活率都不太理想,短期内很难获得大量的商品苗木。而若借助高温、高湿环境进行扦插,则不但成活快,繁殖量多,还能在当年就培育出较理想的株形,提供商品花上市。扶桑性喜温暖湿润气候,最适宜生长温度为25～30℃。扦插育苗在温室条件下虽全年都可进行,但以春、夏季最为适宜。春季扦插可于2～4月在温室内进行。此时外界气温开始回升,“地气”上升,室内土温已达18℃以上,对插条愈合生根极为有利。为节省温室用地,提高基质温度,插床可用厚0.5厘米、高30厘米的玻璃条,
Fusifing propagation with the conventional method of cutting the general survival rate is not ideal, in the short term it is difficult to obtain a large number of commodity seedlings. If the high temperature and high humidity environment for cutting, then not only live fast, breeding more, but also in the year to cultivate the ideal plant shape, to provide goods to market. Hibiscus like hi warm humid climate, the most suitable growth temperature of 25 ~ 30 ℃. Cutting seedlings in the greenhouse conditions can be carried out throughout the year, but the most suitable spring and summer. Spring cuttings can be carried out in the greenhouse from February to April. At this point the outside temperature began to rise, “ground gas” rise, the indoor soil temperature reached 18 ℃ above, the cutting root healing is extremely beneficial. To save greenhouse land, increase the substrate temperature, slotting available thickness 0.5 cm, 30 cm high glass,
