桂花很少用种子繁殖。这是因为其种子具有后熟性,一般随采随播后,受各种因素(如温度、湿度、害虫等)的影响,往往出苗率低或不出苗。所以通常沙藏后再播,以提高萌芽率。但笔者经实践摸索,感到桂花种子随采随播并非不行,只要搞好保温、保湿、透气、防害工作,萌芽率可达90％以上。方法如下: 一、采种及处理桂花的果实为核果。4～5月,当果实外皮由淡绿转为紫黑色时,表明已成熟,可进行采收。采收后及时除去果皮,清洗干净,获得种子。同时除去空壳、哑壳等不正常的种子,余下的在25℃左右的温水中浸泡24小时。二、播种及方法 Osmanthus seldom used seed breeding. This is because the seed has a maturity, usually with the companion, by a variety of factors (such as temperature, humidity, pests, etc.) the impact of the emergence rate is often low or not sprout. So sand is usually broadcast afterwards to increase the germination rate. However, I practice the exploration, I feel osmanthus seeds with the companion does not work, as long as good insulation, moisturizing, breathable, anti-injury work, budding rate of up to 90%. The method is as follows: First, seed and deal with osmanthus fruit as stone fruit. From April to May, when the skin of the fruit turned from light green to purple-black, it indicates that it has matured and can be harvested. Remove the peel promptly after harvest, clean it and obtain the seeds. At the same time remove the shell, dumb shell and other abnormal seeds, the remaining soaked in warm water at 25 ℃ for 24 hours. Second, sowing and methods
