Abstract

In Korea, mowing the grass of a grave (Beolcho) is a very important event preceded by Chuseok (Korean thanks giving day) and Si-Hyang (annual ancestral feast). Because Beolcho usually takes place one or two weeks before Chuseok, the traffic accidents on roads are getting worse and safety accidents are getting more and more. Erroneous Beolcho methods can cause the soil to be exposed and cause the loss of soil or the low shoot density of graveyard grass or weed occurrence. Therefore, the dispersion of the Beolcho timing and the approprite method can be import issues. The present study assessed the effects of grass mowing timing and height before Chuseok on the growth of Zoysia japonica and Z. matrella. The mowing timing was evaluated at 1 week, 2 weeks, 3 weeks, and 4 weeks before Chuseok, and the mowing height differently according to the two type of grass. In Z. japonica, the faster mowing before Chuseok, the longer the plant height, and the coverage rate and shoot density were higher. In Z. matrella, the faster mowing, the longer the shoot length, but the coverage rate and shoot density did not show any difference or tendency. As compared to Z. japonica, the plant height of Z. matrella was kept short regardless of the time of mowing. In both grasses, the plant height was shortened when mowing was done at low cutting height, but the coverage rate and shoot density were decreased. In addition, it was shown that it is advantageous to maintain the shoot density of graveyard lawn by 40-50 mm or 30-40 mm cutting above the ground for Z. japonica or Z. matrella, respectively.

우리나라에서 벌초는 추석 성묘와 시향에 앞서 이루어지는 매우 중요한 행사이다. 벌초는 보통 추석 1-2주 전에 집중해서 이루어지기 때문에 전국적으로 도로의 교통체증이 심해지고 안전사고의 발생도 점점 많아지고 있다. 잘못된 벌초 방법은 흙이 드러나 토양 유실을 유발하거나 묘지 잔디의 밀도 저하와 잡초 발생의 원인이 되기도 한다. 다라서 벌초시기의 분산과 올바른 벌초 방법은 매우 중요한 문제일 수 있다. 본 연구에서 벌초 시기는 추석 1주전, 2주전, 3주전, 4주전 잔디 깍기 처리를 두었고, 벌초 방법에서는 잔디 깍는 높이를 달리하여 들잔디와 금잔디의 생육에 미치는 영향을 평가하였다. 들잔디에서 추석과 시향 시기를 기준으로 잔디 깍기 시기는 빠를수록 초장이 길었으나 피복률과 밀도는 높은 경향이었다. 금잔디에서 잔디 깍기 시기는 빠를수록 초장이 길었으나, 피복률과 밀도는 각각 차이가 없거나 일정한 경향을 보이지 않았다. 들잔디에 비해서 금잔디의 초장은 잔디 깍기 시기에 관계없이 짧게 유지되었으며 피복률과 밀도도 높게 유지되었다. 벌초는 들잔디와 금잔디 모두 짧게 할 수록 초장이 짧아졌고, 피복률과 밀도도 낮아졌다. 또한 벌초 시 들잔디와 금잔디는 각각 지상부의 40-50 mm or 30-40 mm 남겨둘수록 묘지 잔디의 밀도유지에 유리한 것으로 나타났다.
