| The Chinese medicinal plant-Radix Scrophulariae,mainly distributes in Zhejiang,Anhui, Jiangsu,Fujian,Jiangxi,Hunan,Guizhou,Shanxi,Chongqing such as places.In recent years,along with the industrial production and modernized advancement of the traditional Chinese medicine, Radix Scrophulariae,as the dried root of Scrophularia ningpoensis Hemsl.,its demand increases day by day with its cultivation territory and the cultivated area.Following the growth,development dissimilarity of Radix Scrophulariae on different cultivation territory,its corresponding quality,effective component content and accumulation exist biggish difference.The research in this paper,we took the medicinal plant-Radix Serophulariae (Scrophularia ningpocnsis Hemsl.) as the object of study,used the cultivation experiment,selected the different experimental field soil,adopted the lama management of large field,carried on the synchronized monitor of its development under different soil condition,and executed the contrastive analysis of its growth,development,physiological characteristic,medication spot,effective component content,as well as the accumulation situation and so on,in order to provide more systematical theory basis and data support for AP cultivation and the quality rating of Radix Scrophulariae under the different soil condition.In this paper,the main content and purpose of the study are as follows:1.According to the geographical environment of experimental area and the cultivation history of Radix Scrophulariae,we selected nine experimental fields for the cultivation condition.The first choice of selection method was to adopt the cultivation staff and the local science and technology technical personnel carrying on the macroscopic preliminary designation;Once more,to sample the soil in different time and carry on the determination of its potential of hydrogen,the moisture content,the bulk specific gravity,mechanical pellet elements and nature,quality of material,organic matter,nitrogen,phosphorus,potassium as well as copper,zinc,iron,manganese such as elements, combining with its determination target,growth target,development situation in different time as well as target conditions of its major and trace elements,carrying on the classification and determination of the electoral district experimental field,we fixed on the type of cultivation experiment land finally.2.To sample and handle Radix Scrophulariae in each growth periods regularly,latter monitor the nitrogen,the phosphorus,the potassium such as major element of each growth spot, simultaneously exam copper,the zinc,the iron,the manganese and such as trace element in various soils,times and material spots,carry on the comparative analysis to the determination target,we have determined the best growth type for Radix Scrophulariae in various experimental fields and obtained the quite comprehensive knowledge and understanding of its growth and development.3.Through examining the root of Radix Scrophulariae in different soil in different times,we carried on the general quality detection and the appraisal to Radix Scrophulariae separately, including the moisture content,the ash,the extractives and HPLC content contrastive analysis of the effect ingredient.We carried on the comprehensive nature appraisal of its growth and development in different soil to the determination result,by this instructing cultivation and practice. In this paper,the main conclusion of the study is as follows:1.Through the sample determination of the southwest region mountain cultivation soil,we know that the southwest region Chongqing section,the Radix Scrophulariae cultivation soil type divides into three kinds,two great particle sizes,five big quality of material soil category,namely limestone,yellow soil,purple ochre three kinds;loam,heavy loam two kind of particle size types and emery powder nature,powder nature,powder sandy,granulated substance mucilage,sandy five idioplasms.This soil is meta-acid,the acidity(pH 4.55～5.29) in overall performance;The moisture content performance is the high elevation region watery(localization value 18.81%～22.32%);it displays the experimental field high curing degree in the soil bulk specific gravity(localization value 0.05～49.07 g·cm-3).The soil which includes many organic matters(1.76～3.02%) and good structure is suitable for the growth and cultivation of Radix Scrophularia.2.To monitor the sample of Radix Scrophulariae regularly,the synthesis regular examination of its own element as well as other chlorophyll content,the adult plant target,we took the superiority land parcel which favor the growth of Radix Scrophularia as representatives.We confirmed the effective calcium content,the soil maturation,pH to be highest,high nitrogen,potassium, magnesium,calcium,high moisture content,high organic archery target,the heavy loam emery powder nature limestone class soil which is suitable for the growth and cultivation of Radix Scrophulariae.On the contrary regarding,high manganese,low pH value,heavy loam powder nature class soil,although not too favoring the growth and cultivation of Radix Scrophulariae as a whole,but we may consider the new research and innovation to the soil being suitable for Radix Scrophulariae under the cultivation measure and the agronomy method. 3.To carry on the quality determination to the medicine root of Radix Scrophulariae in different soil and month,its result satisfied the quality and soil relevant variance analysis,and the fit and unfit quality sufficiency conformed to five broad heading soil difference attribute,namely:the first kind is a limestone class,heavy loam emery powder nature,high nitrogen,potassium,magnesium,calcium, high moisture content,high organic matter,high curing soil;Simultaneously it surpassed the powder sandy type,loam high phosphorus,low potassium,low calcium of the fourth kind;Next,it surpassed high manganese,low pH value and heavy loam of the second kind;Once more,it surpassed heavy soil granulated substance class,yellow soil high potassium,copper,low nitrogen,phosphorus, manganese content,the organic archery target of third-order;In finally it surpassed the loam sandy class,purple ochre high zinc,low calcium,low organic archery target of the fifth kind.It has manifested the quality suitability soil selectivity of Radix Scrophulariae,and conformed to original intention and the goal of the experiment.From this,it has provided the development selectivity,growth effectiveness,prepared medicine spot relevance for Radix Scrophulariae which constituted its cultivation growth pattern together.It also provided the mentality and the reference for the ecology and the quality research of Radix Scrophulariae. |
