초록

유기농 쌀 생산시 잡초방제에 효과적인 농산부산물의 이용체계를 찾고자 쌀겨, 볏짚+쌀겨, 보리짚+쌀겨를 비료원으로 시용하여 벼를 재배할 때의 잡초억제효과 및 쌀 수량의 변화를 검토한 결과는 다음과 같다. 쌀겨시비 초기에 유모에 발생하는 생장장해는 이앙 후 살포량이 증가된 120/180kg 10a-1에서 2～4일이 지속되었다. 쌀겨시비에 의해 용존산소 농도가 2mg L-1이하로 낮아졌으며, 이앙 후 21일 까지 유지되었다. 농산부산물 이용 체계별 잡초억제효과는 보릿짚+쌀겨에서 높았다. 쌀겨 분시 방법별 잡초억제효과는 이앙 후 살포량이 많았던 120/180kg 10a-1분시에서 높았다. 쌀겨 처리답의 잡초 억제 가능기간은 살포 후 30일 내외였다.

영어초록

This experiment was conducted to evaluate the restriction effect of rice growth and rice growth by agricultural by-products for fertilizer, rice bran, barley and rice straw in the machine transplanting rice paddy field. The inhibition of rice to the different volume of rice bran was at the plot which rice bran 120 and 180kg 10a-1 were treated at 3 days before transplanting and 1 day after transplanting, respectively, and it's symptom lasted for a few days. The concentration of dissolved oxygen by treatment of rice bran was less than 2mg L-1, these sign was continued by 21 days after transplanting. The weed inhibition by different application of agricultural by-products was most effective at plot treated systematically with rice bran and barley straws. The effect of weed inhibition by treatment methods of rice bran was the most effective at the plot which rice bran 120 and 180kg 10a-1 were treated at 3 days before transplanting and 1 day after transplanting, respectively. The period for weed inhibition by agricultural by-products was limited within 30 days after their treatment.
