不同栽培模式对铁皮石斛产量和品质的影响

Effects of Different Cultivation Modes on Yield and Quality of Dendrobium Officinale Kimura et Migo

铁皮石斛是中国特有的名贵药用植物,在中国区域经济中发挥重要作用。栽培模式的选择对铁皮石斛的产量和品质十分重要。该研究选用大棚床栽与3种林下栽培模式,测定铁皮石斛的生长和品质指标,并利用隶属函数法进行综合评价。结果显示:大棚床栽对铁皮石斛的伸长生长促进效果最佳,林下附生栽培明显增加铁皮石斛的产量;相比大棚床栽,林下附着物栽培显著提高铁皮石斛粗纤维、生物碱、总黄酮和蛋白质的含量;4种栽培模式中,附着物栽培综合评价效果最佳,林下床栽效果最差。

Dendrobium officinale is a unique and valuable medicinal plant in China,which plays an important role in regional economy.The selection of cultivation mode is quite important for the yield and the quality of Dendrobium officinale.In this study,the growth and quality indexes of Dendrobium officinale were determined by using greenhouse bed planting and three kinds of under-forest cultivation modes,and evaluated by membership function method.The results showed that:Greenhouse bed planting had the best effect on the elongation growth of Dendrobium officinale,and under-forest epiphytic cultivation significantly increase the yield of Den-drobium officinale.Compared with greenhouse bed cultivation,the contents of crude fiber,alkaloids,total flavonoids and protein in Dendrobium officinale were significantly increased by under-story attachments cultivation.Among the four cultivation modes implemented in this study,under-story attachments cultivation was the best,and the effect of bed planting under forest was the worst.
