Study on the Quality of Whole Silage and Yield by Stage of Maturity of Rye Plant I. Change of composition and yield by stage of maturity of whole crop rye plant

호맥의 생육시기별 수량과 Whole crop silage의 품질에 관한 연구 I. 호맥의 생육시기별 수량 및 성분변화

This experiment was conducted to find out the change of composition and yield of whole crop rye plant by the maturity stage such as boot, heading, milky, dough and yellow ripe. The results of this experiment were as follows: The yield of whole plant was significantly (P<0.01) higher in the dough stage than in the other stages, and stalk yield of whole plant was significantly (P<0.01) higher in the dough stage than in the other stages, and stalk yield of whole plant was the highest in the part of whole plant, ear yield in the yellow ripe stage. Leaf and stalk yield in the ratio of part yield to whole plant yield remarkably decreased according to the passage from boot to yellow ripe stage, but ear yield increased. Dry matter yield increased with advancing maturity stage, and was the highest in the yellow ripe stage (P<0.01). Crude protein contents of whole plant and each parts gradually decreased, and crude fiber content increased with advancing maturity stage.

호맥(胡麥)의 생육시기별(生育時期別) 생초(生草) 및 건물소화율(乾物消化率)과 부위별(部位別) 생산량(生産量) 및 이들 시기별(時期別)로 일반성분(一般成分)과 생산량(生産量)을 비교(比較)하기 위하여 수잉기(穗孕期), 출수기(出穗期), 유숙기(乳熟期), 호숙기(糊熟期) 및 황숙기(黃熟期)의 5단계로 나누어 실시(實施)한 시험결과(試驗結果)를 요약(要約)하면 다음과 같다. 1. 생육시기별(生育時期別) 생초수량(生草收量)은 호숙기(糊熟期)가 가장 많았으며(P<0.01), 부위별(部位別)로는 줄기가 가장 많으나 이삭의 양(量)은 황숙기(黃熟期)가 가장 많았다(P<0.01). 2. 부위별(部位別) 비율(比率)은 생육(生育)이 진행(進行)됨에 따라 잎과 줄기는 전체(全體)에 대한 비율(比率)이 현저히 감소했으나, 이삭은 반대현상으로 증가(增加)하였다. 3. 건물량(乾物量)은 생육(生育)이 진행(進行)됨에 따라 증가(增加)하여 황숙기(黃熟期)에 생산량(生産量)이 가장 많았다(P<0.01). 4. 생육(生育)이 진행(進行)됨에 따라 잎, 줄기, 이삭 및 전체(全體)의 조단백질함량(粗蛋白質含量)은 점차로 감소하고 조섬유함량(粗纖維含量)은 반대(反對)로 증가(增加)하였다.
