以观赏蕨类栗柄金粉蕨为试材,研究了其孢子繁殖关键技术。结果表明:将成熟孢子播撒于腐殖土上,约5d萌发长出原丝体,55d左右发育为成熟配子体,65d左右完成受精,随后长出幼孢子体。播种4个月后,幼孢子体长到3~5cm时,进行分株处理,分株2个月后进行分盆处理,炼苗2个月后,成苗定植于露天。从孢子到繁殖园艺用苗定植,全程8个月,1株野生植株可以成功繁殖出园艺苗3 000余盆。
In order to observe the fern chestnut Fern Fern as test material, the key technology of its spore propagation was studied. The results showed that the mature spores were sown on the humus soil, the protonema grew and grew out about 5 days, the mature gametophytes developed on the 55th day, fertilized after 65 days, and then the sporophytes grew out. After sowing for 4 months, when the sporophytes grow to 3 ~ 5cm in length, the ramets are treated by ramets. After 2 months of ramets, the ramets are divided into two groups. After 2 months, the seedlings are planted in the open air. From spores to reproductive horticulture Miao colonization, the entire eight months, a wild plant can successfully reproduce horticultural seedlings more than 3,000 pots.
