- W773587789 abstract "본 시험은 논에서 가축분뇨를 활용하여 수수<TEX>${times}$</TEX>수단그라스 교잡종 재배시 생육특성, 수량 및 토양중의 질산태 질소의 변화를 구명하기 위하여 2003년부터 2005년까지 3년간 축산연구소(수원) 포장에서 시험을 실시하였으며 그 결과를 요약하면 다음과 같다. 수수<TEX>${times}$</TEX>수단그라스 교잡종의 생육특성 중 초기생육은 화학비료구 4.3에 비하여 가축분뇨를 시용한 경우 <TEX>$2.5{sim}3.8$</TEX>로 양호하였고 1차 예취후 재생은 화학비료구 3.0에 비하여 돈분액비, 발효돈분구는 각각 2.8로 양호한 반면 발효우분구는 4.1로 불량하였다. 가축분뇨별 시용수준 간에는 가축분뇨 100% +화학비료 25%> 가축분뇨 75%+화학비료 25%> 가축분뇨 100% 순으로 생육이 양호하였다. 건물수량은 화학비료에 비하여 돈분액비 23%, 발효돈분 18% 증수되었으나, 발효우분구는 12% 감소되었다. 또한 TDN 수량도 같은 경향으로 돈분액비 시용구에서 24%, 발효돈분 시용시에 18% 증가되었으며 발효우분의 경우는 12% 감소되었다. 사료가치는 가축분뇨를 시용함으로 조단백질 함량이 화학비료 시용구 5.9% 보다 다소 낮아지는 경향으로 돈분액비 5.6%, 발효돈분 5.4%, 발효우분 5.5%이었다. 가축분뇨의 시용방법 간에는 일정한 경향이 나타내지 않았다. RFV에 있어서도 화학비료구가 81로 가장 높았으며, 가축분뇨를 시용한 구에서는 다소 낮아지는 경향으로 돈분액비 77, 발효돈분 77, 발효우분 79 이었다. <TEX>$NO_{3^-}N$</TEX> 용탈량(2년 평균)은 평균 돈분액비구 <TEX>$37.0mg/{ell}$</TEX>, 발효 돈분구 <TEX>$32.9mg/{ell}$</TEX>으로 많았으며 발효우분구는 <TEX>$17mg/{ell}$</TEX>으로 적었다. 가축분뇨 시용수준 간에는 가축분뇨 100%+화학비료 25%>가축분뇨 75%+ 화학비료 25%>가축분뇨 100% 순이었으며 가축분뇨의 종류에 관계없이 시용 초기에 용탈량이 많았다. The experimental work was conducted to determine the growth characteristics, yield and feed value of sorghum-sudangrass hybrid and <TEX>$NO_{3^-}N$</TEX> leaching by application of various types of livestock manure (LM) at National Livestock Research Institute, Suwon, for 3years (2003-3005). The growth characteristics in chemical fertilizer (CF) was better than others in general. The growth characteristic of sorghum-sudangrass hybrid by the various type of LM was good in order of composted swine manure (CSM) > liquid swine manure (LSM) > composted cattle manure (CSM), whereas the growth characteristics by application level of LM was good in order of LM 100%+CF 25%>LM 75%+CF 25%>LM 100%. Dry matter(DM) yield in LSM and CSM increased by 23% and 18% respectively while DM yield in CCM decreased 24% as compared to CF. Moreover total digestible nutrients (TDN) in LSM and CSM increased by 24% and 18% respectively while TDN in CCM decreased 12% as compared to CF. Crude protein and relative feed value in LM decreased compared to those in CF. <TEX>$NO_{3^-}N$</TEX> leaching by application level of LM showed that there was an increase in order of LM 100%+ CF 25%>LM 75%+CF 25%>LM 100%. Also the high concentration of <TEX>$NO_{3^-}N$</TEX> occurred shortly after application of LM." @default.
