| 摘要: |
| 于2002年11月在广西南丹县河池林业科学研究所浅山丘陵区的缓坡杉木林地,按照《DB42/213盾叶薯蓣栽培规程》的种植方法,用1级、2级、3级和4级种用根茎进行盾叶薯蓣(Discoria zingiberensis C.H.Wright)大田种植对比试验,分别测定盾叶薯蓣栽培1年和栽培2年的产量和薯蓣皂素含量。结果显示,播种第1年栽培期盾叶薯蓣出苗率为1级种 > 2级种 > 3级种 > 4级种,在栽培满1年后的生长期中各级别的植株苗蔓长势差别不明显;盾叶薯蓣栽培满1年时各级别种茎产量为1级种 > 2级种 > 3级种 > 4级种,薯蓣皂素含量为2级种=3级种 > 4级种 > 1级种;栽培2年的产量为1级种 > 2级种 > 3级种 > 4级种,1级种和2级种产量差异不显著,其他各级别种茎之间产量差异极显著;栽培2年后薯蓣皂素含量为4级种 > 3级种 > 2级种 > 1级种,3级种和4级种含量较高但差异不显著,其他各级别种茎之间有效成分含量差异极显著。建议选用2年生根状茎作种时,宜选用当年新萌生形成的芽头作种。 |

| Abstract: |
| According to the planting technique list in Planting Rules of Discoria zingiberensis C.H. Wright DB42/213,a comparative experiment is conducted on Discoria zingiberensis C.H. Wright in Fir woodland along glacis of foothill by Hechi Forestry Research Institute of Nandan County, Guangxi. There were total four classes of Discoria zingiberensis C.H.Wright that are planted according to the quality of bud of the biennial rhizome of Discoria zingiberensis C.H.Wright segment.The experiment was supposed to examine the stem yield and Diosgenin content of Discoria zingiberensis C.H.Wright in the one-year cultivation and two-year cultivation.The experiment result shows that in the first year cultivation the bud growing rate is:class 1 > class 2 > class 3 > class 4.There was no noticeable difference among them in young plant growing speed after one-year cultivation. After one year of cultivating, the stem yield is:class 1 > class 2 > class 3 > class 4;the Diosgenin content is:claas 2=class 3 > class 4 > class 1. After two years of cultivating, the stem yield is:class 1 > class 2 > class 3 > class 4 while there is no significant difference between class1 and class2 but the diferneces between the rest two classes is significant.The Diosgenin content:class 4 > class 3 > class 2 > class 1 after two years of cultivating. The content of class 3 and class 4 is almost of the same high level, but there is still some diference between class 1 and class 2. The experiment reveals that newly growing buds of the year should be taken into the first consideration in choosing the bienial rhizome as seed. |
