摘要
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。
Tetragold annual ryegrass was introduced and planted in Nanjing area. The growth adaptability and matter accumulation pattern were studied. The results were as follows: tetragold annual ryegrass adapted well to the south region. The yield of whole growth period were 234d. It characterized as high quality grass. With the development of growth period, content of crude protein of the grass decreased, contents of dry matter and crude fibber increased, but the ratio of dry matter changed from high to low to high again. The ratio of dry matter is lowest at the beginning of stem elongating.
