Study Quality In Different Ages And Stems Of Ginseng

Ginseng (Panax ginseng C.A.Meyer) is famous herb medicine which are planted at large area in Jilin province, and it is mainly produced in Changbai Mountain in Jilin province area. Recently, the ginseng medicinal value gradually has been taken seriously, and ginseng industry develops fast, but due to the long production period, the production cost is very high, thus it limits the development of ginseng industry. Therefore, how to improve the output of ginseng is the big problem of cultivated. The photosynthesis area of much stem ginseng is larger, which can improve the photosynthetic efficiency, so it can improve the output of ginseng. In order to study the rule that different growth stages of ginseng saponins in different stem leaf number ginseng how to changed. Born three stems, two stems and single stem ginseng of three to four years old as the research object and take ginseng saponins as testing indexes to Compare the variation.Acquisition set different stem number and different growth stages of ginseng in Ji’an. Using Ultrasonic extraction method to extract ginseng saponin. The total content of ginsenosides was determined by using ultraviolet spectrophotometry and the content of Re,Rg1,Rf,Rd,Rc,Rb1,Rb2,Rb3, Rg2this9kinds of mono ginsenosides was measured by using HPLC, Then compare the variation. The photosynthesis area much stem ginseng is larger, which can improve the photosynthetic efficiency, so as it can improve the output of ginseng. The experimental results are as follows:1. ginseng saponins content increased with the growth years; In different birth period, born in three or four years, ginseng in the red fruits have the highest content of total ginseng saponins, Respectively4.46%,4.94%,4.97%,6.69%,5.00%.). Different stem several ginseng, double stem ginseng total ginsenosides higher than single stem ginseng and three stem the ginseng of total ginsenosides. There have different monomers in the root of ginsenosides in different period.Overall, At different growth stages,the monomer saponins have the highest content of Rbl in red fruits, Four years of double stem high of1.035mg/g; and wilt when Rd content of the lowest. Three years of single stem content lowest0.105mg/g.Different stem several ginseng, double stem ginseng monomer ginsenosides higher than single stem ginseng and three stem the ginseng of monomer ginsenosides. The ginseng sponins content have closely relation with growth period and the number of stem. So we suggest that ginseng should do double stem process in plant period.And Ginseng should be harvested in the last of red fruits.2. different ages and stems of ginseng large elements by Atomic absorption spectrometry, The experimental results show that, no matter total nitrogen, total phosphorus, or total potassium, from exhibition leaf stage to the flowering period they are showing a downward trend. Total nitrogen content of3years stems ginseng is and higher than four years stems one, total nitrogen content reached minimum during green fruiting period, content of total nitrogen reached highest in red fruits period; the flowering terms contains minimum total phosphorus; Total potassium content reached highest; For different reproduction stages of the stem and ginseng, content and form of nutrient absorption and utilization showed regular changes through main nutrient determination analysis.3. different ages and stems of ginseng trace elements by Atomic absorption spectrometry, The experimental results show that, In different growth stages of China railway, manganese, copper, zinc content of Fe relationship Fe> Mn> Zn> Cu. Different stem see count, trace element is also with age and increased, And3years> double stem single stem3years,4years> double stem4years three stem>4years single stem.
