감초의 일반적인 재배양식은 실생묘 및 포복경으로 경영비 중 종묘가격의 비중이 매우 높고 생존율이 낮은 단점이 있다. 이러한 단점을 극복하기 위하여 생력화된 육묘방법 개선을 위하여 트레이 육묘를 활용한 육묘방식을 검토하고, 다양한 지대에서 감초를 확대 재배하고자 재배양식별 수량과 품질을 비교하고, 년생에 따른 종자채종 효율을 비교 검토하며, 표고별 및 친환경 유기물 시용에 따른 감초산 함량의 변이를 분석하고자 한다. 이러한 재배양식 간 수량 및 품질을 비교함으로써 고품질, 생력, 안정생산기술을 패키지화하여 신기술로써 농가에 보급한다.

Licorice(Glycyrrhiza spp.) demand most are dependent on imports. Licorice domestic demand for medicinal plants, as well as food additives, cigarette manufacturing as an additive in various forms and uses can be used. Is expected to continue to increase imports. National safety production based on the composition and the need to expand the supply of high quality materials needed food, medicines, etc. Regions of China and Mongolia, wild licorice taken banned the production and export was reduced. Licorice imported unstable eventually. Licorice imported into Uzbekistan, Pakistan turns than Glycyrrihiza uralensis the importation of European licorice(G glabla L. var) is increasing. The efficacy and safety of imported licorice increased and diversified use in securing a stable supply for domestic demand-based self-insufficient expansion is urgently needed. Eco-friendly cultivation and high-quality safety technology, it is necessary to establish the differentiation of imported and domestic.
Consumers want safe agricultural production and soil pollution prevention and eco-friendly method of cultivation is necessary to establish. Enhance good agricultural Practical(GAP) enforcement of organic cultivation techniques, pest control, cultivation and soil management, etc. complementary research is needed.
1. Quality comparison by altitude and cultivation methods
Cheorwon(200m), Jeongseon(400m) and Taebaek(700m) in the quality and quantity of comparative tests. Compare the yields and quality of the seedlings, a creeping shoot, and direct seeding. Seedlings and a creeping shoot is a common methods. But expensive price seedling and low survival is a big problem. In order to solve these problem, direct Seeding and plug seedling were investigated. As a result, the purchase cost savings and faster time to seedlings than seedlings were able to reduce operating costs as much as 25%. Plug seedling, it was confirmed that the effort and has a cost savings. Was three years cultivating licorice yields by comparing the results Cheorwon (200m)> Jeongseon(400m)> Taebaek(700m) in the order of yields. Yields seedlings(226kg/10a)> Direct Seeding (199kg/10a)> a creeping shoot(172kg/10a) were in this cultivation. Compare content of glycyrrhizin altitude and between cultivation methods was not observed significance. Not exceed pharmacopoeia regulations for all treatments glycyrrhizin acid content of 2.5%. Comprehensive direct seeding cultivation are considered as the most economical method of cultivation.
2 Seed production to increase efficiency in the technology development
Licorice seed is hard seed coat. The low germination rate due to hard seed coat, however, cause a problem of low seeding in field. Production of licorice seeds is very difficult. Also not have much success. Licorice is a perennial plant that grows in the dry desert climate. Over the June-July rainy season flowering, pod fungus, or by other causes will be lost. Licorice rain shelter facilities within the seed production should. And Pollen ability of licorice floral structure monoecious development of organs and fertility was not a big issue for the results. Pollen on agar plates could be observed that more than 50% germination. External environmental factors are considered difficult to licorice seed production. Flowering by treatment with calcium(CaCl2, CaNO3) and growth regulator agent(gibberelin), deletion and fertilization efficiency were evaluated. As a result, a difference in seed characteristics(grain weight, seed shape) was not observed. The palisade cell layer is closely related to moisture absorption. Therefore, waxing in the seed coat removed, the normal moisture absorption is possible. Grinding surface seeds to increase germination licorice was a physical injury to the abrasive-type rice milling machine. Increased germination rate and germination speed investigated the germination characteristics was confirmed. Seed production was most 4 years old plant 9.4k/10a harvest. Licorice seeds production facilities from 4 years old was the best out of rain shelter.
3 Development of eco-friendly organic farming techniques.
Consumers prefer eco-friendly organic cultivation of medicinal crops. Reduce the use of chemical fertilizers in order to prevent soil pollution from agriculture. Full-fermented compost and mixture oli cake, in order to replace chemical fertilizer trial compared the growth and yield of licorice. Favorable price and consumer eco-friendly organically grown medicinal crops cultivation. Licorice roots that use medicinal plants. Eco-friendly organic fertilizers such as mixture oli cakes and full-fermented compost, spread on the farm without chemical fertilizers than the quantity and quality differences in income sides is favorable. From the test results were yield compared between eco-friendly organic and chemical fertilizers, statistical significance was not observed. That can be applied directly to the farmers could be confirmed. The full-fermented compost was higher than glycyrrhizin acid mixture oli cakes and chemical fertilizers.
