ABSTRACT
OBJECTIVE： To provide reference for promoting large-scale， standardized and high-quality planting of Chinese medicinal materials. METHODS： Through the communication by phone with the agriculture bureau of each district and county， the contact with the relevant township government and the field visit investigation during Jun. 2013-Dec. 2018 by Lanzhou institute for food and drug control， variety， area， yield and output value， cultivation techniques and processing methods of Chinese medicinal materials in the planting area of Lanzhou were investigated and statistically analyzed. The advantages and problems were analyzed， and reasonable suggestions for planting Chinese medicinal materials were put forward. RESULTS & CONCLUSIONS： In 2018， artificial planting of Chinese medicinal materials in lanzhou has a certain scale， with 21 artificial planting varieties， a total planting area of about 510 000 mu， an annual output of 170 000 tons， an annual production value of over 1.7 billion yuan. Cultivation techniques mainly include seedling transplanting， mulching or direct seeding， while drying is the main processing method. Artificial planting of Chinese medicinal materials in Lanzhou has a certain scale and prominent characteristic varieties； authenticity is guaranteed， and the combination of Chinese medicinal materials planting and tourism drives economic development. However， there are still some problems， such as a certain distance from the development of industrialization， variety degradation， backward basic research， serious natural disasters. It is suggested to strengthen its propaganda and expand its advantages， at the same time， enhance government support， develop and construct planting bases of Chinese medicinal materials， strengthen the awareness of good agricultural practice （GAP）， strengthen scientific research strengeh， explore breeding techniques of fine varieties of Chinese medicinal materials， develop insurance of Chinese medicinal materials， and guarantee the development of planting industry so as to promote large-scale， standardized and high-quality planting of Chinese medicinal materials.

ABSTRACT
BACKGROUND:Posterior arch length deficiency is closely related to the formation and development of malocclusion. OBJECTIVE:To measure the posterior arch length in individual normal occlusions of adults in Lanzhou. METHODS:A total of 102 current col ege students with individual normal occlusions, with a mean age of (19.33±2.67) years (range 18-24 years), including 47 males and 55 females from Gansu Province, were chosen to take lateral cephalograms. Al research objects were divided into three groups according to mandibular plane angle:high angle group (Frankfort mandibular-plane angle>32°), low angle group (Frankfort mandibular-plane angleRESULTS AND CONCLUSION:Posterior arch length of maxil ary arch was slightly longer in male group than that in female group, and the difference was not significant (P>0.05). The posterior arch length of mandibular arch was slightly longer in male group than that in female group, but the difference was no significant (P>0.05). Comparison between groups revealed that the posterior arch length of low angle mandibular arch was significantly longer than that of high angle mandibular arch in male group, and the difference was significant (P<0.05). The results indicate that the gender wil not influence the development of posterior arch length. Different vertical facial types and different genders have different posterior arch length in individual normal occlusions of adults
