不同肥水搭配对一年生何首乌品质的影响
通过盆栽控水的方式,以何首乌扦插苗为材料,采用L9(3^4)正交试验设计,研究了不同氮、磷、钾肥水搭配对1年生何首乌品质的影响。结果表明:1年生何首乌水分和灰分未超过中华人民共和国药典2010版规定的10.0%、5.0%,二苯乙烯苷含量均达到中华人民共和国药典2010版规定的不少于1.0%,而结合蒽醌没有达到中华人民共和国药典2010版规定的不少于0.1%。综合分析,盆栽水肥最优搭配组合为:氮肥施用量0~2.32g,盆,P2O5施用量0~2.16g/盆,K2O施用量3.00g/盆,土壤持水量为80%。...

Summary: | 通过盆栽控水的方式,以何首乌扦插苗为材料,采用L9(3^4)正交试验设计,研究了不同氮、磷、钾肥水搭配对1年生何首乌品质的影响。结果表明:1年生何首乌水分和灰分未超过中华人民共和国药典2010版规定的10.0%、5.0%,二苯乙烯苷含量均达到中华人民共和国药典2010版规定的不少于1.0%,而结合蒽醌没有达到中华人民共和国药典2010版规定的不少于0.1%。综合分析,盆栽水肥最优搭配组合为:氮肥施用量0~2.32g,盆,P2O5施用量0~2.16g/盆,K2O施用量3.00g/盆,土壤持水量为80%。 |

The results indicated that, the moisture and ash contents of annual Polygonum muhiflorum did not exceed 10.0% and 5.0%, respectively, and the content of 2, 3, 5, 4'-tetrahydroxystilbene-2-O-β-D- glucopyranoside and combined anthraquinones were not less than 1.0% and 0.1%, separately. Although the former one met the requirements of the People's Republic of China Pharmacopoeia (2010 Edition), the latter one didn't. In a word, by comprehensive analysis, the combinations |
