费菜的繁殖方法有扦插、分株、压条、播种,其中扦插中也包括叶插。在这几种方法中以扦插和分株为主,而用种子繁殖尚待进一步研究(各繁殖法见图)。 1.扦插①枝插要求温度15～30℃,以20～25℃最为适宜。南方地区3月中旬至5月中旬为最适期,其次为10月至11月上旬。6～9月气温高,湿度大,容易烂苗;12月到次年2月气温太低,不易生根。北方地区4月中旬至6月初为扦插适期,冬季扦插应在温室中进行。 Propagation methods of feeders have cuttings, ramets, battens, sowing, including cuttings also include leaf plug. In these methods to cuttings and ramets mainly, and breeding with seeds is yet to be further studied (the breeding law see map). 1. Cuttings inserted branch requirements temperature 15 ~ 30 ℃, 20 ~ 25 ℃ most appropriate. The southern region from mid-March to mid-May for the most suitable period, followed by October to early November. June to September high temperature, humidity, easy to rotten seedlings; December to February next year, the temperature is too low, not easy to root. The northern region from mid-April to early June for the cutting period, winter cuttings should be carried out in the greenhouse.
