Effect of Nutritional Environment in Ginseng Field on the Plant Growth of Ginseng (Panax ginseng C. A. Meyer)

Abstract

This study aims to establish the directions for the optimal nutrient contents determined by soil and leaf analyses. The study is to be used as a source for basic information in investigating the effects of nutritional environment on ginseng growth at the fields of Ansung region in Gyeonggi province. The physical property of soil porosity is closely related to ginseng growth, with more than 50% of good growth in the field. The optimal range of chemical properties in soil was analyzed as 0.20-0.28% T-N, 500-900 mg/kg Av.P 2 O 5 , and 2.3-3.5 cmol + /kg Exch.Ca. The optimal range of inorganic nutrient contents in leaves was also analyzed. P value was less than 0.25%, and Mg was more than 0.22%. Other elements were not found clearly. The ratios of N/P, N/Mg, K/Mg, and Ca/P of leaves with good growth in the field showed 10<, 10-13, <14, 1<, respectively. In addition, the Ca:Mg:K ratio of the Exch.cation (cmol + /kg) may be useful as an indicator in the assessment of plant growth in ginseng.

Contribution of soil and crop parameters on sudangrass productivity based on farm survey

“…따라서 양분 손실을 최소화하면서 작물의 수량과 품질을 향상시키기 위해서는 수단그라스 재배지의 토 양 및 식물 영양 특성을 파악하고 두 특성 간에 미치는 영향에 대한 분석을 통해 생산성을 평가하고 적정 비료량을 설 정하는 것이 중요하다. 복숭아, 인삼, 딸기, 키위, 구지뽕나무 등의 작물은 토양화학성과 식물체 잎의 양분함량과의 관 계를 바탕으로 적정 비료 기준을 제시한 바 있다 (Seo et al, 2002;Jin et al, 2009;Choi et al, 2010;Kim et al, 2022;Song et al, 2022). 따라서, 본 연구에서는 수단그라스 재배농가의 수량에 따른 질소비료사용량, 토양화학성, 식물체 질소함량, 질소이용효율 등을 분석하여, 생산성에 대한 환경 또는 재배요인의 영향을 평가하고자 수행하였다.…”

Diversity of Fungal Endophytes in Various Tissues of Panax ginseng Meyer Cultivated in Korea

“…Ginseng saponins, also known as ginsenosides, have a specific chemical structure compared to the saponins of other plants and have different, extensive effects as antitumor, antidiabetic and antioxidant compounds and as cholesterol-reducing agents [2-5]. The growth of ginseng plants requires 4 to 6 years of cultivation under shaded conditions, and ginseng cultivation is affected by the soil environment due to the long cultivation period in the same soil [6]. One major problem is the complication of disease caused by different pathogenic fungi during the long cultivation period.…”
