Abstract

This study was conducted to find out the optimum cropping system for the stable production of forage crops in the newly reclaimed land located at Gwanghwal and Gyehwa region of Saemangum reclaimed tide land from October, 2009 to October, 2011. Whole crop barley (WCB), Rye, Italyan-ryegrass (IRG) as winter crops and Corn, Sorghum${\times}$sudangrass hybrid (SSH) as summer crops were cultivated. Soil chemical properties, nutrient uptake, feed value, growth and yield were examinated. The testing soil was showed saline alkali soil where the contents of organic matter, available phosphate and exchangeable calcium were very low, while exchangeable sodium and magnesium were higher. Changes of soil salinity during the growing season of forage crops were less than 0.2%, and the growth of forage crops was not affected by salt injury. Standing rates of winter crops were higher in the order of Rye, WCB, and IRG, while the dry matter yield of winter crops was higher in the order of IRG, Rye and WCB. The highest crude protein (CP) content was recorded in IRG, and total digestive nutrients (TDN) contents were increased in the order of WCB, IRG, and Rye. The TDN content was higher in corn, whereas other feed value was higher in SSH. The content of mineral nutrients on stem, leaf and grain in IRG, Corn were high. After experiment pH was lowed, contents of exchangeable magnesium, sodium and organic matter were decreased while contents of total nitrogen, available phosphate and exchangeable potassium, calcium were increased. Winer crops and summer crops after continually cultivating in cropping system, fresh matter yield increased, compared to WCB-Corn (74,740 kg $ha^{-1}$), IRG-SSH 10%, IRG-Corn 7%, Rye-SSH 6%, Rye-Corn and WCB-SSH 3%. Dry matter yield increased, compared to WCB-Corn (20,280 kg $ha^{-1}$), IRG-SSH 7%, Rye-SSH 6%, IRG-Corn/Rye-Corn/WCB-SSH 3%. The TDN yield increased, compared to WCB-Corn (13,830 kg $ha^{-1}$), IRG-SSH 2%, WCB-SSH and IRG-Corn 1%. Therefore, we suggest that the crop combination of IRG-SSH and WCB-SSH would be preferred for silage stable production.

본 연구는 새만금간척지 광활 및 계화지구 신간척지에서 조사료의 안정생산을 위한 적정 작부체계를 설정코자 2009년 10월부터 2011년 10월까지 수행하였다. 동계 사료작물로 청보리 (영양), 호밀 (곡우), 이탈리안 라이그라스 (passerel plus)와 하계 사료작물로 옥수수 (광평옥), 수수${\times}$수단그라스 (G7)를 재배하여 토양화학성, 양분흡수량, 사료가치, 생육 및 수량성을 검토하였다. 시험전 토양은 유기물, 유효인산 및 치환성칼슘 함량이 매우 적었고 치환성마그네슘 나트륨 함량이 많은 알칼리성 염류토양 이었다. 재배기간 동안 토양염농도 변화는 0.2%이하를 나타냈고 염피해는 없었다. 동계 사료작물 입모율은 호밀 > 청보리 > 이탈리안 라이그라스 순으로 양호하였고 생초 및 건물수량은 이탈리안 라이그라스 > 호밀 > 청보리 순으로 높았다. 조단백 함량은 이탈리안 라이그라스 > 청보리 > 호밀 순으로 총가소화영양 함량은 청보리 > 이탈리안 라이그라스 > 호 밀 순으로 많은 경향을 나타냈다. 하계 사료작물 조단백질 및 중성용매불용성섬유, 산성용매불용성섬유 함량은 수수${\times}$수단그라스에서 총가소화영양 함량은 옥수수에서 높았다. 동 하계 사료작물 경엽 및 곡실의 무기양분 함량은 이탈리안 라이 그라스와 옥수수에서 높았다. 시험 후 토양화학성은 pH가 낮아지고 총질소 및 유효인산, 치환성칼륨.칼슘 함량이 증가한 반면에 유기물, 치환성마그네슘 나트륨 함량이 감소되는 경향을 나타냈다. 동작물과 하작물을 연계한 수량성 ('10~'11)에서 생초수량은 청보리 - 옥수수 (74,740 kg $ha^{-1}$) 대비 IRG - 수수${\times}$수단그라스 10%, IRG - 옥수수 7%, 호밀 - 수수${\times}$수단그라스 6%, 호밀 - 옥수수 및 청보리 - 수수${\times}$수단그라스 3% 증수되었고 건물수량은 청보리 - 옥수수 (20,280 kg $ha^{-1}$) 대비 IRG - 수수${\times}$수단그라스 7%, 호밀 - 수수${\times}$수단그라스 6%, IRG - 옥수수 3%, 청보리 - 수수${\times}$수단그라스 3%, 호밀 - 옥수수 3% 증수되었으며 TDN수량은 청보리 - 옥수수 (13,830 kg $ha^{-1}$) 대비 IRG - 수수${\times}$수단그라스 2%, 청보리 - 수수${\times}$수단그라스 및 IRG - 옥수수 1% 증수되었다. 따라서 생초, 건물수량 및 TDN수량이 높은 "IRG - 수수${\times}$수단그라스" 및 "청보리 - 수수${\times}$수단그라스" 조합을 신간척지 토양특성 (사양토, 배수약간불량, 토양염농도 0.2% 이하)에 알맞은 사료작물 작부조합으로 판단되었다.
