摘要
搜集穿心莲种质资源19份,进行种植试验和生物学性状调查,结果表明:各地种植的穿心莲种子纯度不一致、混杂严重,主要存在大叶型和小叶型两种生态类型;不同产地的穿心莲干品重量差异显著,大叶型的茎叶平均干重明显高于小叶型的茎叶平均干重,说明大叶型穿心莲的产量、产值较小叶型穿心莲具有明显的优势。
To have collected 19 varietis of Andrographis paniculata idioplasm resource,and to have planted and investigated about their biology characters, as a result: the seed pure degree of Andrographis paniculata is differ and serious intermix, but there are mostly two zoology varietis, big foliage type and small foliage type, there are obviously different with weight of dry medicinal material ,stem's and leaf's average dry weights of big foliage type are more hefty than that of small foliage type, it is account for that the yields and production values of big foliage type are obviously prior to that of small foliage type.
