对用塑料大棚、塑料小拱棚和露田栽植等３种不同覆盖管理方式的３年生人工蕨菜的生长发育进程、地上茎的生长量及藓菜产量进行了观测和分析，结果表明：塑料大棚内光、温、湿条件比较适合蕨菜生长发育的要求，因而蕨菜出苗早、生长量大，产量高；塑料小拱棚对棚内温、湿条件和蕨菜生长发育及产量也产生一定影响，比露田蕨菜具有一定增产效果，但较大棚效果为次
The growth and development of 3-year-old artificial bracken, the growth of above-ground stems and the production of moss sprouts were observed and analyzed with 3 plastic coverings, plastic small shed and open field planting. The results showed that: Light, temperature and humidity conditions more suitable for the growth and development of fern requirements, and thus fern emergence early, the growth of large, high yield; shed plastic shed temperature and humidity conditions and the growth and yield of Bracken also have a certain impact, Bracken compared with the field has a certain yield-increasing effect, but the effect of larger shed times
