摘要
以桂草1号王草、热研4号王草和杂交狼尾草3个狼尾草属牧草为材料,开展了2年品种比较试验,结果表明:桂草1号王草的平均鲜、干草产量分别为375.62、70.17 t/hm2,极显著高于热研4号王草和杂交狼尾草的产量;桂草1号王草的扦插成活率、宿根的越冬率分别为96.67%、100%,极显著高于另外2个参试品种;桂草1号王草的粗蛋白含量最高,茎叶比最小的是杂交狼尾草,因此,桂草1号王草可在闽北地区推广种植。
A two -year contrast test was carried out with three kinds of pennisetum, which were King Grass Guimu - 1, Pennisetum purpureum x P. typhoideum cv. Reyan No. 4, and P. americanum x P. purpureum. The results showed that the average wet weight and hay yield of King Grass Guimu - 1 was 375.62 t/hm2 and 70. 17 t/hm2, respectively. The yield of King Grass Guimu - 1 was very significantly (P〈0. 01) higher than that ofP. purpureum x P. typhoideum cv. Reyan No. 4 and P. americanum x P. purpureum. Cutting survival rate and overwintering rate of biennial root of King Grass Guimu - 1 was 96.67% and 100%, respectively. Both of them were extremely significantly (P 〈 0.01 ) higher than that of the other two varieties. King Grass Guimu - 1 had the highest content of crude protein (CP), and P. americanum x P. purpureum had the minimum stem -leaf ratio. Integrated analysis implied that King Grass Guimu - 1 could be popularized and planted in north of Fujian.
