Background : Cynanchum wilfordi is a typical myocardial medicinal crop. Because it penetrates more than 1m, it requires a lot of labor and harvesting costs. In addition, we needed 4 - 5 times of weeding until July, and in the soil with poor drainage, root rot disease occurs and yield is greatly reduced. Therefore, this study was conducted to develop new cultivation technology that can minimize the effort cost and increase the yield. Methods and Results : As a test material, container standards were used plume tube of diameter 30 ㎝ × height 50 ㎝, 80 ㎝, 100 ㎝. The culture soil manufactured by mixing cokofit 60%, peatmoss 10%, pearlite 6%, vermiculite 10%, zeolite 5%, and charcoal 5%. The compost was made by mixing fowl droppings 45% and cattle manure 5%. The mixing ratio of the culture soil and the compost was 100 : 0, 90 : 10, 80 : 20, 70 : 30, respectively, and the mixture was filled in the container. Cynanchum wilfordi seedling sow raising seedlings during one month seeds become dormancy breaking. Culture soil and container of Cynanchum wilfordi was effective 87% increase (384 ㎏/10 a → 720) in quantity contrast conventional culture in height 50 ㎝ container + culture soil 100 : 0. 80 and 100 ㎝ containers were found to be unsuitable for production throughout the year because of thin thickness of subterranean part and low commercial yield due to the long time required for roots to reach the hardpan layer. The yields of compost mixture decreased from 0% (720 ㎏/10 a) > 10% (642) > 20% (560) > 30% (475) in 50 ㎝ containers. When the compost content was more than 20%, the yield decreased due to physiological damage during the early growth. Conclusion : The culture soil and container cultivate for harvesting ease of Cynanchum wilfordi was effective saving more than 15 times more than the harvest time contrast manpower harvest and the yield was increased by 87%. Also, container cultivation was effective the cost cutting of installation dismantlement and redres since no need to move the cultivation area.
Background : Cirsium japonicum seeds is the high price, less than 40% germination rate is low. There is a need for a method developed to increase seed germination rate increases consumption. Also, by measuring the harvest season each functional ingredients contents was performed to investigate the optimal timing harvest of ingredients that target. Methods and Results : Test materials were used Cirsium japonicum seeds harvested from late May until mid-June in medicinal testing ground. GA3(0, 25, 50, 100 ppm), Kinetin(0, 25, 50, 100 ppm) and KNO3(0, 25, 50, 100 ppm) of Growth regulator were treated, it examined the population grew more than 1 ㎜. Contents of functional components to harvest season analyzed by HPLC after pre-treatment harvested and drying the leaves and roots in late august until early November. Germination rate of the growth regulator treatment was higher by 52% from the full ripening brown seeds GA3 100 ppm, 56% in the Kinetin 50 ppm, KNO3 treatment in 52% germination in 25 mM. The white seed germination rate was low at less than 10% of all growth regulator treatment. Functional ingredient content of leaf according to harvest time were higher respectively Rutin is 8.61 ug/g in late october, apigenin is 59.6 ug/g in beginning november, quercetin is 8.61 ug/g in beginning september, kaemferol is 32.9 ug/g in late september. Very low content in roots, there was no significant difference. The main ingredient silymarin was highest 4.36 ㎎/g at the late september in case of leaf, and syringin was maintained at a high level from mid-september to early october. Conclusion : Seed germination is thought to be able to increase the germination through the growth regulator treatment and assort brown seed. Functional components according to the harvest time is determined to be able to improve effective component when processing harvest to select a high yield by the component for the purpose.
Background : Aralia cordata and Polygonum multiflorum GAP cultivation requires a stable drying and storage settings after harvesting. therefore, this experiment was performed in order to effectively manage the physical, chemical and biological hazards. Methods and Results : Test materials were used biennial Aralia cordata, Polygonum multiflorum harvested from the medicinal testing ground. The drying temperatures were treated with 40, 50, 6 0℃ and natural drying. Storage containers were stored in plastic boxes, styrofoam boxes and kraft paper containers, examined the color and quality changes for eight months. Aralia cordata and Polygonum multiflorum drying temperature is dry it took natural drying 720 hours, 40℃ hot air drying 180 hours, 50℃ hot air drying 168 hours and 60℃ hot air drying 108 hours. However, the difference chromaticity of the Lab value corresponding to the temperature does not appear, it was good to dry in a short time at 60℃. Aralia cordata and Polygonum multiflorum stored in a styrofoam box storage method but can be stored at room temperature for up to four months, began to decay caused by moisture content it continues to increase. In plastic box in case of Aralia cordata and kraft vessel in case of Polygonum multiflorum can be stored for eight months in room temperature without decay. Styrofoam boxes stored at 5℃ cold storage were higher water absorption such as room temperature, but decay did not occur. Plastic box and styrofoam box were a tendency such as room temperature. Conclusion : Aralia cordata and Polygonum multiflorum are thought that the color change is not large depending on the drying temperature the lower the water content. Styrofoam storage box, the air permeability is higher than plastic boxes and containers Kraft vessel, decay occurs expected increase.
