一、播种繁殖。播种繁殖一般适宜于大批量繁殖,但不易保持品种特性。10月种子成熟时,及时采收晾干,用小布袋装好放在通风干燥处。次年3月播种。播种前用0.2%高锰酸钾液浸泡消毒24～48小时,清洗后置于40℃～50℃温水中,自然冷却浸泡2～3天,捞出后稍晾片刻。 First, planting and breeding. Seeding and breeding generally suitable for high-volume breeding, but not easy to maintain variety characteristics. When the seeds are ripe in October, they should be harvested in time and dried in a well-ventilated, dry place with a small cloth bag. The following year sowing in March. Prior to sowing with 0.2% potassium permanganate solution disinfection for 24-48 hours, after cleaning placed in 40 ℃ ~ 50 ℃ warm water, soak for 2 to 3 days, remove a little dry moment.
