Abstract
This study was conducted to improve the continuous techniques for international competitiveness of ginseng industry to Korea-China FTA negotiation and conclusion, and provide the basic information for ginseng industry development of Korea. It was carried out the visiting of the northeastern three provinces (Jilin, Liaoling and Heilongjang) in China for 3-year from 2014 to 2016 and observed the farmers’ fields of ginseng cultivation with soil environmental status. The types of ginseng cultivation could be observed in small scales of 0.5∼3.0 ha, in middle scales of 4.0∼10.0 ha and in large scales of 30∼700 ha with the kinds of imhasam, Chinese ginseng, Korean ginseng and western ginseng. Also ginseng was cultivated in newly reclaimed land of forest in two types of direct seeding and transplanting of ginseng seedlings. The field beds of ginseng growing were covered with vinyl films in arch design of 100∼130 cm height and vinyl was painted in spraying with blue, green and yellow colours for shading. It was investigated in status of the physico-chemical properties of soils. The physical information on the field soils were silt loam, loam and sandy loam in soil textures, and some plain in low slope, some alluvial fan or local valley in forest of land topography. Soil pH ranged within 5.0∼5.2, soil EC was 0.93∼3.78 dS m -1 , organic matter was 37∼35 g kg -1 , nitrate nitrogen 63∼490 mg kg -1 , available P2O5 55∼163 mg kg-1, and in exchangeable cations, K was 0.30∼0.98, Ca was 6.5∼14.0, Mg was 1.1∼5.3 cmolc kg -1 in ranges. Farmers used the fertilizer for ginseng cultivation in 10∼11 t of compost, 200∼400 kg ha - 1 of complex fertilizer and 750 kg ha -1 of oil cakes. The northeastern three provinces of China can use the newly lands with large areas of ginseng cultivation in soil sickness by continuous cropping. and the soil basic fertility is batter than that of Korean in standard guide of ginseng cultivation soil.
