초록

농촌인력 감소와 지구 이상기상 증가에 따라 콩 재배 시 생력적인 잡초방제 및 토양유실억제 기술이 요구된다. 콩과 동시에 파종한 활물피복용 보리의 잡초발생 및 경사지 토양유실의 억제 효과가 2013, 2014년 2년간 수원 시험포장에서 조사되었다. 활물피복 보리의 지상부 피복량은 파종 후 40일에 200~300 kg/10a, 파종후 60일에 100~200 kg/10a의 건물중을 얻을 수 있었으며 이에 따라 콩의 초기 생육상태에서 잡초발생이 현저히 줄어들었다. 잡초발생량에서 보리 활물피복은 토양처리제와 같은 억제효과를 나타내었다. 콩 식물체 초기생육량은 활물피복 보리와의 경합으로 인해 많이 감소하였는데 활물피복 보리가 하고 됨에 따라 콩의 후기생육은 많이 회복되어 수확기에서는 무피복구의 70~80%를 나타내었다. 콩 종실 수량은 2013년에 무피복구가 생육이 과번무하여 활물피복구보다 감소하였다. 그러나 2014년에 무피복구에서 적심 처리하였을 때 종실수량이 증가하였는데 보리활물피복구와 수량의 차이가 없었다. 따라서 활물피복 재배도 관행재배(무피복)와 비슷한 수량성을 확보하는 것이 가능하였다. 경사지의 토양유실 시험에서는 보리 활물피복에 의해 유거수량이 약 20~50%, 토양유실량이 약 70~90% 감소하여 토양유실 억제효과가 컸다. 2014년 비닐+보리활물피복도 토양유실억제 효과는 보리활물피복구와 같았다. 콩과 동시에 파종한 보리의 활물피복 이용은 종실수량의 큰 감소 없이 생력적으로 잡초를 관리할 수 있고 경사지의 토양을 보전하는 효과가 커서 앞으로 유망 시 되는 기술이라고 할 수 있다.

Reduction in the occurrence of weed and erosion of slope soil by living mulch barley simultaneously sown with soybean were investigated at the Upland Experimental Field in Suwon City in 2013 and 2014. The aboveground dry matter of 200-300, 100-200 kg/10a of living mulch barley was obtained at 40 and 60 after sowing, respectively. The occurrence of weeds was significantly reduced by barley living mulch. The early growth of soybean was reduced significantly because of the competition with barley living mulch, but the late growth of soybean after natural drying of barley living mulch was recovered considerably. The soybean grain yield with barley living mulch was similar to that of the normal soybean cultivation, showing no significant difference between no mulch and living mulch treatments. With respect to soil erosion on the slope soil, the amount of run-off water decreased by 20-50% and the amount of soil loss decreased by 70-90% by barley living mulch. The reduction in soil erosion by the use of plastic film + barley living mulch was similar to that of only barley living mulch. The barley living mulch in soybean production can be a promising cultivation technique as it reduces weed occurrence and soil erosion without grain yield reduction.
