摘要

近年来由于绞股蓝的过度采收,野生资源面临枯竭的危险,为了扩大绞股蓝植物的资源,人工栽培势在必行。1990~1993年在皖东琅琊山进行林下人工栽培试验。结果表明,在粗放管理的条件下,林下种植绞股蓝是可行的,选择适合的种源及林分郁闭度是关键因子。在刺槐林下栽培产量可到3300kg/hm

Abstract

The wild resources Gynostemma pentaphyllum(Thunb .) Makino decreased obviously in recent years since over harvest, therefore. it is necessary to build a basis for production. A cultivated investigation in some forest lands has been done for three years (1990-1993) at the Langya Mountain of Chu County, Anhui Province. The results showed that to build an agroforestry ecosystem for the extensive management  of (Gynostemma under forest is advantageous, the major factors are the selection of forest land and its shadow density. Based on the comparative studies in three years in different forest stands, the production of dry weight reaches up to 3 3 0 0 kg / hrn2 per year under black locust platation with 0.5 -0. 6 shadow density, the content of saponin is more than 5. 0%.
