Background : Acreage of rain-shelter plastic greenhouse to prevent anthrax is being gradually increased according to growing importance of safe Boxthorn production. But When Boxthorn is grown in the hot season in rain-shelter plastic greenhouse, Fertility decreases. The fertilization rate tends to be different according to cultivated variety and ventilation type of rain-shelter plastic greenhouse. Therefore it is necessary to identify cause and look for a solution. Methods and Results : In the experiment, ‘Cheongun’ cultivar was grown in the rain-shelter plastic greenhouses for the tests. Environment of rain-shelter plastic greenhouses, fertilization rate and density of flower visiting insect were investigated according to ventilation type. Pollen germination and pollen tube elongation on stigma were investigated according to temperature. In mid-July, the temperature on a clear day rose to 45℃ in rain-shelter plastic greenhouse of side vents. Pollen germination and pollen tube elongation on stigma were normal for 3 hours on 30, 35℃. Fertilization rate was somewhat reduced on 40℃ but Pollen germination and pollen tube elongation was good. On 45℃, fertilization rate was very poor and There was no pollen germination. Density of flower visiting insect in rain-shelter plastic greenhouse of roof and side vents was higher than that in rain-shelter plastic greenhouse of side vents. The fertilization rate on high temperature did not show any difference regardless of ventilation type. The rate of artificial cross-fertilization and airborne fertilization were high in rain-shelter plastic greenhouse of roof and side vents. It was necessary to improve airborne fertilization rate because airborne fertilization rate was significantly lower than artificial cross-fertilization regardless of ventilation type. Conclusion : When it was cultivated in rain-shelter plastic greenhouse, the reasons for the lowering of the fertilization rate were as follows. Density of flower visiting insect was low. Boxthorn, which was insect pollination crop, was needed sufficient flower visiting insect on flowering period. But it was insufficiency especially in rain-shelter plastic greenhouse of side vents. Another reason was decrease in pollen germination and pollen tube elongation. Pollen germination was suppressed in the high temperature.

Background : As the farmers who grow Chinese matrimony vine (Lycium chinense Miller) in rain-shelter greenhouses increase, it is necessary to develop a cultivar with self-compatibility and high quality. Methods and Results : The new boxthorn line, CBP06419-243 was selected from the cross between CBP03310-250(IT232705) and CBP05399-1 to breed the cultivar with self-compatibility and high quality. These lines used for crossing was tetradilpoid induced by the colchicine treatment on bud. Its preliminary yield test was performed from 2009 to 2011 and the selected line was named Cheongyang 18. Its regional yield trials were carried out in Cheongyang, Yesan and Jindo from 2012, 2014, 2015 and Cheongyang 18 was registered as the new variety, Whasu, in 2015. The specific characteristics were summarized as follows; Tree shape is semi-open type and the leaf is lanceolate. The flowers are distinctly larger. The fruit type is medium size, long oblong and yellowish red. The flowering was June 21 with medium flowering. Branching by pruning its sprout was generated less than the check variety, Cheongmeong. The infection rates on leaves to Eriophys macrodonis Keifer was as strong as 7.7 percent. Anthracnose on fruits in open field was slightly severe compared to the check variety, but the infection rates in rain shelter greenhouses was similar. The content of betaine and free sugar in dried-fruits were higher than that of the check. The dried-fruit yield was decreased about 13 percent in open field, but increased 18 percent in rain shelter greenhouses. Conclusion : This variety ‘Whasu’ was suitable for cultivation in plastic film greenhouses because of self-compatibility and high-yielding. It is not necessary the companion variety.

Background : To diversify and increase the demend of Boxthorn, it is breeding for medicinal herbs, food and fresh fruit. Therefore Ningxia with the high sugar content and Black Fruit Containing a lot of functional ingredients have been used for cross breeding. As a result, many new lines were developed. Therefore It was carried out to use as a data for new varieties through the characterization of good lines. Methods and Results : 12 varieties and lines were investigated. Diploid boxthorn were Chengmyeong (Lycium chinense Mill.), Ningxia (Lycium barbarum L.) and Black Fruit (Lycium ruthenicum Murray). Tetraploid boxthorn is Whasu. Breeding Lines were CB13593-8, CB13595-4, CB13592-9, CB13596-1, CB13597-37, CB14643-43, CB14622-2 and CB14626-4. The fruit of lines crossed with Black Fruit (Lycium ruthenicum Murray) were round. The various lines were breeded with black fruit, good fruiting and good soil adaptability. Leaves were small and thin in Compared with tetraploid Boxthorn, Whasu. Sugar content was very high in CB14643-43, CB13595-4, CB13597-37 and CB13593-8. So it’s good for fresh fruit. Conclusion : CB14643-43, CB13595-4, CB13597-37 and CB13593-8 lines were good for fresh fruit because of high sugar content of the fruit. CB14622-2 and CB13596-1 lines were good for food because of fruit color, seed weight and number of seeds. But these are required function component analysis.

Background : Liriope platyphylla Wang et. Tang belongs to the Liliaceae and herbal medicinal plants. It is usually grown as ground cover plants. But the farm is cultivated medicinal plants in order to harvest its tuberous root. The cultivated area is 95ha and the production is 588 ton(2014). Miryang and Cheongyang are the main producing areas. This experiment was carried out to select a cultivar that are well adapted in middle regions in Korea. Methods and Results : It were investigated the tuber characteristics in four cultivars of Liriope platyphylla Wang et. Tang. The ratios of roots and tubers a plant was ranged 18.6 - 21.6%. Maekmundong 1 have more in tubers per a plant but lower in the rate of marketable tubers and 100-tubers weight than other 3 cultivars. Cheongshim was heavier and larger in tuberous root than 3 other cultivars. The tuber’s distributions in less than 10 ㎝ soil depth at the surface was 48.6% in Cheongshim, 58.4% in Seungsu 50.6% in Maekmundong 1 and 58.1% in Cheongyang native’s line. So, Seungsu and Cheongyang native’s line are believed to be suitable for harvesting by machines. The tuber’s yield was highest in Seungsu and was 5% higher than Cheongyang native’s line. The spicatoside A extracted with 80% MeOH was analyzed by 0.01 – 1.83 ㎎/g and Maekmundong 1 have been contained much more than other cultivars. Conclusion : Considering the yield and medicinal ingredients, Maekmundong 1 have good quality than Cheongshim, Seungsu and Cheongyang natives’s lines in middle regions in Korea.

Background : Liriope platyphylla Wang et. Tang is a perennial plant and its tuberous root is used as herbal medicine. Liriope platyphylla is grown throughout a year from April to April of next year. Recently, the production was lowered because of severe drought/rainfall and injury by successive cropping. The ridge height affected the growth of shoots and roots as affected by drought or rainfall. It is necessary to establish the cultivation techniques for stable quantity per unit area and good tuber’s quality. This experiment was carried out to select a cultivar of good tuber quality and to determine the ridge height for high-yielding. Methods and Results : It were investigated the characteristics of roots and tubers depending on different ridge heights in four varieties of Liriope platyphylla Wang et. Tang. There was not significantly different in shoot growth by different ridge heights. The tubers distribution in less than 10cm soil depth at the surface was decreased about 6.6% in the 15cm ridge height compared to 5cm. So, the mean distributed position of tubers was deepened at higher ridge. The cultivars that tubers were mainly distributed in the 10cm depth from surface was Seoungsu and Cheongyang natives’s lines. The no. of tubers per a plant and the ratio of marketable tubers were increased about 13.2% and 20.1% in the 15cm ridge height compared to 5cm. Considering the tuber sizes and ratio of marketable tubers, Cheongshim and Maekmundong 1 has good quality than Seoungsu or Cheongyang natives’s lines. The tuber yield increased about 19.5% in the 15cm ridge height compared to the 5cm. So, high ridge was advantaged to increase the yield. Conclusion : From the above results, the quality and quantity of tubers of Liriope platyphylla Wang et. Tang was good in the higher ridge. We recommended Cheongshim cultivar because of the large tuber sizes and high ratio of marketable tubers.

Background : Liriope platyphylla Wang et. Tang is a species of Liliaceae and its tuber is used as medicinal herbs. This medicinal plant is mainly cultivated in Cheongyang and Buyeo of Chungcheongnam-Do and Miryang of Gyeongsangnam-Do. It is necessary to establish a cultivation techniques for stable production to solve the problems that are found on farms. These farm surveys were carried out to obtain the basic data on soil environment and cultivation conditions at main producing areas of Chungnam-Do in Liriope platyphylla Wang et. Tang. Methods and Results : The surveys were investigated from 37 farmers in Cheongyang and 32 farmers in Buyeo who cultivate Liriope platyphylla Wang et. Tang. There were slightly differences in the local characteristics between Cheongyang and Buyeo. The rate of successive cropping for more than 3 years were 19% at Cheongyang and 41% in Buyeo. The reason may be due to the a small-owned field. It has grown 28% at Cheongyang and 59% at Buyeo in paddy fields. The injury by successive cropping that farmers argued were the increasing pest/disease occurrence, degradation of tuber quality and yield reduction. Crops planted after the harvest of L. platyphylla were mostly Pepper or soybean in upland. It is necessary to reduce the injury of successive cropping. The results of 112 soil analysis data were classified by 8 soil series. There are many acidic soil, lack of organic matter, excess phosphate. However, it did not analyzed the influences on the growth and yield of the crop as affected by different soil conditions. Conclusion : From the above results, it is necessary to develop cultivation techniques on the reduction of injury of successive cropping, such as cropping system, seedling transplanting cultivation, cultivation methods for good agricultural practices(GAP) and soil improvement.

Background : Usually, planting and harvest time is around the middle of April. A labor shortage deu to her planting time as harvest time and some farmers were late planting culture. After planting until take rooting It will take more than one month when late planting growth is bad. Seedling cultivation, just taking rooting is agricultural growth promotion. Methods and Results : So did design the optimum nursery days and number of plants. Nursery days were 30 days and 45 days and number of plants 1, 3, 5 plants. Plant length was longer in less number of plants while Root length was longer in more number of plants of Temporary planting seedling, Leaf number was a big increase but number of plants was not a big shift. In post-havest survey, plant length was longer in 3 number of stem and root length was longer in one number of stem. 45 days and 3 number of stem seedling was the most good in number, weight and length of tuberous root. Yield of 45 days and 3 number of stem seedling was higher 7% than 1 number of stem seedling and higher 5% than 5 number of stem seedling. 45 days and 3 number of stem seedling was 1,789 thousand per 10a in income was the most. Conclusion : Result of this study, for rasing healthy seeding nursery days 45 days and number of plants 3 plant

Background : Acreage of rain-shelter plastic greenhouse to prevent anthrax is being gradually increased according to growing importance of safe Boxthorn production. But When Boxthorn is grown in the hot season in rain-shelter plastic greenhouse, quantity of Boxthorn decreases. therefore the research was carried out to investigate Fertilization mode. Methods and Results : Chungwoon was very strong self-incompatibility. Chengyangjaerae, Chengyang18 and CBP11542-206 was self-compatibility. Artificial fertilization rate was slightly higher in roof and side vents than in side vents of rain-shelter plastic greenhouse in hot season. Pollen sterility due to high temperature is not critical because artificial fertilization rate was high in side vents of rain-shelter plastic greenhouse in hot season. Airborne fertilization rate was significantly lower in all varieties. Open fertilization rate was higher in roof and side vents than in side vents of rain-shelter plastic greenhouse Conclusion : Roof and side vents was good in compared to side vents in rain-shelter plastic greenhouse of Boxthorn because of high Airborne and open fertilization rate. Self-compatibility varieties were better than self-incompatibility varieties in rain- shelter plastic greenhouse because of high open fertilization rate.

This study aims to present about current status of logistics in Mongolia. As a landlocked country have limited the role of a maritime transportation is a very poor country. However, Mongolia is a rich country in mineral resources in the world and became a center of increasing international trade. Therefore, Mongolia wants to develop logistics as other developed countries using a strategic location. Mongolia uses international port for transit China and Russia by railway. First, this paper focuses on discussing the current situation of logistics. Second it points out some issues currently facing by the governmental policy to promote. Finally, this paper presents some recommendations for developing logistics in Mongolia. The geographical remoteness of Mongolia which results in high cost of transport causes problems for trade relations with the rest of the world to grow.
