摘要: |
為確定黃花倒水蓮的適宜采收期,該研究采用國標(biāo)等方法對1~5 年生黃花倒水蓮根系形態(tài)特征、生物量、藥用成分、營養(yǎng)成分和礦質(zhì)元素進(jìn)行了分析。結(jié)果表明:(1)根系形態(tài)(根幅、基徑及一級根徑)和根生物量在前2年增長緩慢,第2~3 年增長迅速,第3年后趨于平緩。(2)不同藥用成分含量在不同栽培年限間存在顯著差異,其中粗多糖在第1年含量最高,皂苷類化合物在第2年含量最高,黃酮類化合物在第4年含量最高。(3)礦質(zhì)元素含量受栽培年限影響較復(fù)雜,Ca、Mg、Mn、Cu 含量在第3年累積至最多,Fe含量逐年降低,Pb含量與Fe含量變化規(guī)律相反。(4)粗蛋白含量呈現(xiàn)先增加后降低的趨勢,總灰分含量與粗脂肪含量呈逐年降低趨勢。(5)黃花倒水蓮在第3年達(dá)到高產(chǎn)量,4~5 年生黃花倒水蓮根中大多品質(zhì)指標(biāo)均處于最低值,第3年為黃花倒水蓮較為理想的采收期。該研究闡明了黃花倒水蓮在不同栽培年限根系的產(chǎn)量指標(biāo)及品質(zhì)指標(biāo)積累動態(tài)變化規(guī)律,揭示了黃花倒水蓮的最佳采收期,為黃花倒水蓮高產(chǎn)優(yōu)質(zhì)栽培提供了技術(shù)指導(dǎo)。 |

Abstract: |
In order to find out the optimum harvest time of Polygala fallax, the study analyzed the root morphology, biomass, medicinal components, nutritional components and mineral elements of P. fallax roots during the 1-5 cultivating years by national standards and other methods. The results were as follows:(1)The morphology and biomass of P. fallax roots increased slowly during the first two cultivating years, and increased rapidly during the 2-3 cultivating years, however the parameters tended to be flat during the 3-5 cultivating years.(2)The contents of different medicinal ingredients varied significantly within the cultivating years, crude polysaccharides reached to the peak in the first year, total saponins reached to the peak in the second year, and total flavonoids reached to the peak in the fourth year.(3)The mineral elements showed various behavior among cultivating years, the contents of Ca, Mg, Mn and Cu accumulated to the maximum in the third year, the content of Fe decreased with increasing cultivating years, and the content of Pb increased with increasing cultivating years.(4)Crude protein content increased first and then decreased, and the same change trends were observed in the contents of total ash and crude fat, both of which decreased as cultivating years increasing.(5)P. fallax reached a high yield in the third cultivating year, and most of the quality indicators in the roots of 4-5 year at the lowest value, and the third year was the ideal harvest period for P. fallax, which provided technical guidance for high-yield and good quality of P. fallax. The results of the study elucidate the dynamics accumulation of P. fallax during different cultivating years and reveal the optimum harvest time of P. fallax. |
