Curcuma Standardized Planting Part Of The Sop

In order to matching with the GAP research of Rhizoma curcumae, this article summarized the herbalogy research, the species research, growth and development regularity, the cultivate technique, the chemistry composition and the pharmacology functions of Rhizoma curcumae in the foundation of extensive literature consulting, at the same time, carried out researches about the habitat investigation, the growth and development regularity and the cultivate technique of Rhizoma curcumae.In the main habitat of Rhizoma curcumae -Taoshan town, Mayu town, Xianjiang town, Bishan town, which belong to Ruian city, Wenchow, we found some problems in the process of Rhizoma curcumae's production through investigation, including the long span of seeding time and harvesting time, to be short of the gon-ginger's quality criteria, the significant difference of growth densities, the extensive management in the field, inappropriate aspersion of agricultural chemicals, chemical fertilizer and herbicide, the continuous cropping year in year out, the low availability of earth, the processing isn't standard enough, etc.This article tracking the growth and development regularity of Curcuma wenyujin first time, in the research with respect to Curcuma wenyujin's growth and development regularity of two production periods, according to its growth status and characteristics of each part in the process of growth, we divided Curcuma wenyujin's whole growth process into the seedling period, the root-stock growth period and dry matter accumulate period.During the seedling period, the organic center was its aerial parts, after entering the root-stock growth period, the organic center displaced to the underground parts gradually, arriving the dry matter accumulate period, then the organic center completely displaced to the underground medical use parts.During the whole growth process of Curcuma wenyujin, especially in the seedling period and the root-stock growth period, Curcuma wenyujin's plant demand large amount of nitrogen fertilizer and potash fertilizer, yet its phosphate fertilizer demanding is comparatively little. We suggest that while apply fertilizer to Curcuma wenyujin, the nitrogen fertilizer should be 12.0kg/acre (calculated on nitrogen element), the phosphate fertilizer should be 3.0kg/acre (calculated on phosphonium element), the potash fertilizer should be 16.0kg/acre (calculated on kalium element).We use the total amount of extractum as evaluation index, simultaneously , combine with the total amount of chemistry composition as well as another medical use part-root tuber's yield and exsiccation rate, carried out the comprehensive evaluation, preliminary determined the suitable harvesting time of Rhizoma curcumae. This article carried out comprehensive evaluation by means of following factors: Rhizoma curcumae's yield and volatile oils content, germacrone and curdione content, together with factors like the economic performance and maneuverability, so as to systematically investigated the cultivate factors of Rhizoma curcumae for the first time, such as seeding time, gon-ginger, fertilizer and simultaneously plant other field crops in adequate proportion, etc. On these grounds, preliminary screening the best cultivate scheme of Rhizoma curcumae.
