As a common Chinese herb, dry ginger is the dried rhizome of Zingiber officinale Roscoe(Farm. Zingiberaceae ). It's useful for removing cold and stomach pain, diarrhea due to cold deficiency, cough, rheumatism and several other uses. It has the ability to lower blood cholesterol and aid in preventing internal blood clots. It is often taken to help combat colds, coughs, and the flu. The volatile oils of ginger are responsible for active medicinal properties as well as for its pungent odor and taste, commonly found in Asian or Indian cooking. It is recorded that planted genus in Qianwei and Muchuang in Sichuan have the higher quality and better curative effects.We dealt with a whole study on morphological,physical-chemical analysis, ontogeny, uptake and distribution of NPK by ginger plants,expecting these studies can give scientific basis for drug quality standard control and fertilizer of dry ginger.The systemic morphological study on the rhizome of ginger showed that is almost the same with other reports. Most of the oil cells in the rhizome are found around the endodermis. The distributive density of oil cells is different from Huangkou ginger to Baikou ginger.A HPLC method was developed for the quantitative analysis of pungent constituents in the ginger drugs from the different rources. The results show that the dry ginger coming from Muchuan Sichuan province has the highest content of 6-gingerol.The volatile oils of the fresh ginger and dry ginger were extracted by traditinal steam distillation methods and analyzed and identified by GC-MS. Over 60 compounds have been extracted from the dry ginger and 40 compounds were identified. The 30 kinds of compounds were identified from the fresh ginger.The major compounds of them were almost the same. The major constituents are a -zingiberene,citral, a -farnesene,etc.Based on the increase of leaves,branches of the rhizome, the cumulation of dry matter, the distribution of photosynthetic production, the change of substance metabolism and the displacement of growth centre, the growth of ginger was divided into fourstages.The last ten-day period of September, when CGRt is equal to CGRr, the crossing of CGRt and CGRr curves may be regarded as the evidence of the transfer from the leaves to the branches of the rhizome.The uptake of NPK by ginger plants changed with growth and development.In the whole life cycle, the uptake proportion of K was the highest,followed by N and P.
