川东獐牙菜的引种栽培研究

A Study on the Introduction and Cultivation of Swertia davidii Franch

川东獐牙菜是我国的一种珍稀药用植物 ,湖南湘西地区是其分布区之一。针对川东獐牙菜野生资源受到严重破坏的情况 ,对其人工引种栽培进行了研究 ,旨在为川东獐牙菜的栽培及保护提供理论依据。研究结果表明 :川东獐牙菜自然状态下结实率高 ,但萌发率不高且随环境条件的不同有不同的休眠期 ,人工栽培状态下结实率与萌发率均高 ,而且种子休眠期较短。小苗引种情况与所选择的栽培条件有很大的关系 ,泥培、沙培和水培中 ,以沙培效果最好 ;高、中、低湿度培养中 ,以中湿度培养效果最好。实验结果同时也表明 。

Swertia davidii Franch is a rare and precious medicinal herb in China and is distributed in the Xiang xi regions of Hunan. Because of the natural resources of Swertia davidii Franch having been destroyed seriously, this paper research systematically the way of artificial introduction and cultivation in order to offer substantial theoretical foundation for protecting of Swertia davidii Franch. The results showed that Swertia davidii Franch had high rate of fructification, low rate of germination and dormant period different with various conditions in the natural state, while had higher rate of germination and shorter dormant period in the artificial cultivation. The circumstances of introduction of the young Swertia davidii Franch plants were relevant with selected condition of cultivation. Sand fostered had the best effect among soil fostered, sand fostered and water fostered, and medium humid had the best effect among high humid, medium humid and low humid. This experiment also showed that the artificial introduction and cultivation of Swertia davidii Franch had been completely feasible.
