胎生狗脊的引种栽培与繁殖

Cultivation and Breeding of Woodwardia prolifera

通过对引种栽培的胎生狗脊的观察和试验,对其生物学特性和物候进行了总结,表明胎生狗脊能够适应南京的气候,并有较高的观赏价值。沙+泥炭(1∶1)和珍珠岩+泥炭(1∶1)两种基质可以做为芽孢幼苗合适的培养基质。高温抑制胎生狗脊幼苗的生长,幼苗在秋李冷凉气候条件下,生长速度要快于夏季。

Through the observation and experiment of introduction and cultivation of the Woodwardia prolifera,their biological characteristics and phenology were summarized.The results showed that the Woodwardia prolifera was able to adapt to the climate in Nanjing and had a high ornamental value. Two kinds substrates of sand ＋ peat （1∶1） and perlite ＋ peat （1∶1） could be used as the cultivation of bacillus seedlings. High temperature inhibited the growth of the Woodwardia prolifera seedling. The seedling growth was faster under the cold weather conditions than in summer.
