Background : The insufficient soil moisture due to spring drought causes the germination rate of ginseng seeds to be remarkably lowered and the low seeding depth causes the roots not to be settled but remain in the surface soil containing moisture, resulting in the ill-shaped ginseng. Especially, in the case of paddy soil, the soil environment is often over-humidified or over-dried, resulting in high rate of occurrence of physiological disorders such as rough skin, yellow-colored root and red-colored root, etc. compared to the upland soil, requiring more care in managing the soil. Therefore, this study was conducted with the aim to investigate the effects of stamping treatment on the direct seeding cultivation in the paddy soil and to investigate the survival and growth characteristics according to the seeding method. Methods and Results : We investigated the effects of stamping on the emergency rate and growth by using rollers (15, 20, 25, 30 ㎏), and also investigated the growth characteristics according to the direct sowing methods (broadcast planting, motorized seeder, semi-automatic seeder, manual seeder, hoop-type seeder). In the emergency rate of 1-year-old ginseng group directly sowing and treated with trampling, the group treated with 25 ㎏ & 30 ㎏ showed the highest emergency rate & growth, and above-ground & underground parts growth of 1-year-old ginseng by sowing method, there was no significant difference between sowing methods, the emergency rate of motorized seeder and semi-automatic seeder was high. Conclusion : In the paddy soils, the 25 – 30 ㎏ stamping after direct seeding showed superior above-ground growth and emergency rate, and there was no significant difference in growth, but motorized seeder and semi-automatic seeder had a higher rate of emergency in 1-year-old ginseng.

토양의 답압이 맥류의 생육에 미치는 영향을 조사하여 다음과 같은 결과를 얻었다. 1. 토양의 답압에 의하여 초형은 포포형으로 되고 초장의 신장은 억제되며 분벽수가 증가하고 뿌리는 근수, 근경이 증대하며 심근성으로 되고 근중이 증가하였다. 2. 토양의 답압에 의하여 엽연소 함량이 높아지고 절단엽편의 수분감손량도 증가하였다. 3. 토양의 답압에 의하여 엽에서 생성하는 Ethylene 량이 증대하였다. 4. 토양의 답압에 의하여 하위절간의 생장이 억제되어 도복되기 어려운 생육형으로 되고 수량이 증대하였다. 이상의 결과로부터 맥류 답압의 효과는 맥류 그 자체에 대한 직접적인 효과와 토양을 답압하는 것에 의한 효과가 있음을 알 수 있으며, 또한 토양 답압의 효과는 엽에서 생성하는 Ethylene 량의 증대로 보아 토양 답압이 맥류 뿌리에 대하여 물리적 자극을 주고 있다는 가능성이 시사되었다.
