南方三种暖季型牧草品种的比较研究

对台湾甜象草、桂牧一号杂交象草、皇竹草进行了为期两年的比较试验研究。结果表明,三个牧草品种均能适应试验环境条件。甜象草、桂草、皇竹草的鲜草年产量分别为220.85t/hm2,163.18t/hm2,186.20t/hm2;粗蛋白含量分别为17.39%,19.02%,20.91%,粗脂肪含量分别为6.37%,5.39%,4.69%;粗纤维含量分别为33.49%,32.22%,33.58%。台湾甜象草较耐寒,越冬后恢复生长快,抗性较强,试验期间未发现病虫害,是一种高产优质的牧草,值得推广应用。

Study on Three Warm-season Forage Breeds in South China

The plant height, tiller number, yield of three warm season forage varieties in south China were studied for two years. The result shows that the three varieties are all accustomed to the environment of experiment condition.
The fresh forage annual yield of the three varieties were 220.85 t/hm2,163.18 t/hm2,186.20 t/hm2 respectively;the crude protein content were 17.39%，19.02% and 20.91%,the crude fat content were 6.37%,5.37% and 4.69%;and the crude fiber content were 33.49%,32.22%and 33.58%.The palatability trail shows that Pennisetum purpureum Schum ev．Taiwan is better than others, in the experiment period, the Pennisetum purpureum Schum ev．Taiwan has stronger cold resistance , grows faster after the winter and no plant diseases and insect pests were found, it is a high yield and high quality forage variety, so it is worth extension and application.
