摘要
本文对日本引入的９个冷地型鸭茅品种的营养动态进行了研究。其结果表明，９个鸭茅品种的粗蛋白质含量随生育期的进展逐渐下降，以抽穗期下降的速度为快；而粗纤维的含量变化恰好相反，随生育期的推移而逐渐增加，抽穗期的粗纤维含量明显增高；粗灰分的含量变化亦呈下降趋势，但下降幅度不大。
The nutrient trends of 9 cool-season orchardgrass cultivars which were from Japan were studied. The results showed that crude protein (CP) contents was the highest at jionting stage. CP contents was decreased with growth and development. Crude fibre (CF) contents was opposite to CP,CF contents was increased with the herbage matruity. Crude ash declined through the growing season. For nutrient variation of orchardgrass, there was a obvious turning point at heading stage.
