The Effect of the Photosynthetic Ability and the Nutritional Status on Dry matter Production and Yield Components of the Rice Plant at the Latter Half of the Growth Stage (수도 생육후기 광합성 능력과 영양환경이 건물생산과 수량구성요소에 미치는 영향)

  • Experiment were conducted to study the photosynthetic ability of several rice varieties and the influence of the drymatter production on the yield components of the rice plant, especially in ripening period. The photosynthetic ability at the ripening period, the varieties were classified into two groups as relatively high capacity and low capacity. With the earlier the transplanting date and the higher the N-content leaf blade, the greater the ratio of reserved assimilates befere heading time to the ear. This could be support the fact that the rate of full-ripened grains or grain yield of 'Tongil' variety may increased by the change of environment condition.condition.

  • This experiment was conducted to compare the change of growth and canopy photosynthesis between transplanting and direct seeding on paddy surface in rice. Total tiller number by the early vegetative growth stage was significantly higher in the direct seeding flooded paddy surface, while it was reversed from later vegetative growth stage in terms of tillering ability per unit period. But total panicle number was higher in direct seeding on paddy surface. Leaf area index, nitrogen content in leaf blade and canopy photosynthetic ability at later vegetative growth stage were lower in direct seeding on flooded paddy surface than transplanting. Biological yield at harvest stge, leaf area index and conopy photosynthetic activity at heading stage were gradually increasing according to nitrogen level increased both transplanting and direct seeding on paddy surface. Leaf area index, canopy photosynthetic activity, however, were lower in direct seeding on paddy surface than transplanting in the same nitrogen level. Nitrogen content per unit leaf area was high in transplanting.

  • This experiment was conducted to establish the intensive Grazing system through the improved pasture utilization of the Hanwoo beef cattle. Intensive grazing period, 2 to 3 days was compared to conventional rotation-grazing period, 5 to 6 days as control. The intensive grazing system which has 2 to 3 days of grazing period, increased forage DM yield(7.33t/ha) by 17% compared to control(6.28t/ha), and contributed to stabilization of the seasonal productivity through the increased DM yield after August. Plant height, feed intake and efficiency of grazing was increased in intensive rotation.

  • 정보통신기술의 비약적인 기술혁신은 인간의 생활에 큰 변화를 가져왔다. 사회전반에 걸친 정보화는 여가의 증대, 교육욕구의 충족, 주거생활의 개선, 생활정보의 확충 등을 통해 생활을 윤택하게 하고 복리증진에 기여하고 있다. 한편, 이러한 정보화는 건물의 지능화를 촉진하여 많은 인텔리전트 건물을 탄생시켰다. 건물의 지능화는 건물의 이용이나 유지관리의 편리성에 크게 기여하는 동시에 보다 효율적인 정보를 제공하므로 양자는 불가분의 관계에 있다. 지금까지는 생산성 향상을 목표로 하는 사무소 건물이 인텔리전트 건물의 대부분을 차지하였으나 이제는 개인정보 욕구의 상승 및 편리한 생활을 지향하는 가정자동화 등에 대한 요구가 높아지면서 주택의 지능화에 관심이 커지고 있는 추세이다.
