초록

본 연구는 한국잔디의 재배기간 동안 생육 및 무기성분 축적량을 조사하여 한국잔디의 재배전략을 수립하는데 기초자료로 활용하고자 수행하였다. 한국잔디의 경우 다른 작물과 달리 시비와 잔디깎기 등과 같은 관리에 따라 생장 및 무기양분 축적에 차이가 있었다. 잔디깎기로 인해 부위별로 무기양분이 손실되는 양에 비해 축적되는 양이 적었다. 무기양분 축적 차이는 있었으나 K, Ca, Mg은 N과 비슷한 양상을 보였으며, 무기양분의 축적 순서는 N > K > P > Ca > Mg 이었다. 이와 같은 한국잔디의 무기양분 축적 및 흡수특성은 재배의 기초로서 시비량의 결정이나 토양관리 면에서 각 무기양분에 대한 요구성과 서로 밀접한 관계가 있다. 한국잔디의 생육 및 밀도율 향상에 따른 생산량을 늘리기 위해서는 생육시기별 무기양분 축적 파악을 통해 생육시기에 맞추어서 효율적으로 양분을 공급하는 것이 바람직하므로 그에 따른 기초 연구가 필요할 것으로 판단되었다.

This research will be utilized as a base line data by researching on growth and the accumulation of inorganic nutrients during the cultivation period of zoysiagrass and also to establish a cultivation strategy of zoysiagrass. It involves the management such as fertilizer and mowing which ultimately led to the difference of growth and accumulation of inorganic nutrients. The accumulation of inorganic nutrients after mowing, the amount of accumulation was small when compared to the amount lost for the shoot, rhizome and root. Difference in the accumulation of inorganic nutrients, but as for K, Ca and Mg accumulation it shows similar aspects to N accumulation. The orders of inorganic nutrients in zoysiagrass were N > K > P > Ca > Mg. The characteristics of inorganic nutrients absorption of such zoysiagrass acts as the foundation of cultivation, and in the aspect of making decisions on the fertilization amount and soil management, it is closely related to the requirement on nutrients. In order to increase the productivity based on the zoysiagrass's growth and density rate improvement, accumulation of inorganic nutrients per growth period needs to be analyzed, and supplying nutrients in an efficient method suitable to the growth period is advisable, so such basic research was necessary.
