对一年生四倍体黑麦草品种特高进行了引进种植和物质积累动态研究。结果表明 ,该多花黑麦草品种具有很好的适应性 ,全生育期 2 34d ,鲜草产量高 ,品质好 ;随着生育期的推移 ,粗蛋白质的含量由高到低变化 ,干物质和粗纤维的含量由低到高变化 ,而干物率呈高—低—高走势 ,拔节初期干物率最低。 The annual tetraploid ryegrass varieties were introduced and planted dynamic accumulation of material dynamics. The results showed that the ryegrass cultivars had good adaptability. The whole growth period was 34 days. The yield of fresh grass was high and the quality was good. The content of crude protein changed from high to low during the growth period, Crude fiber content changes from low to high, while the dry matter rate was high - low - high trend, the lowest rate of dry matter early jointing.
