南方优质象草品种比较试验初报

Primary report on the variety comparative test of high quality Pennisetum purpureum,cv in the southern part of China

2006年～2007年对红象草、桂牧1号杂交象草、矮象草、台湾甜象草、王草、华南象草等6个象草品种进行了比较试验.经过2年观察测定,结果表明,6个象草品种均能适应本试验区的环境条件,台湾甜象草鲜草产量最高达141345.68 kg/hm^2,其次是王草137 798.85 kg/hm^2,桂牧1号杂交象草125 322.6 kg/hm^2,红象草119 179.58kg/hm^2,分别比对照品种华南象草107 183.55 kg/hm^2提高了31.87%,28.56%,16.92%.11.19%;而矮象草叶量多、粗蛋白质含量高,适合饲喂兔、鱼、鹅等小型草食动物;台湾甜象草、红象草的再生性好、高产优质,营养价值与桂牧1号杂交象草相当,有望成为我国南方新的青饲料牧草品种,值得在生产上推广应用.

Six varieties of Pennisetum purpureum, cv were compared to each other from 2006 to 2007,which were Pennisetum purpureum schumab cv. Red, （Pennisetum purpureum, cv. Mott） × （P. americanum × P. purureum ）]cv. Guimu No. 1,Pennisetum purpureum, cv. Mott,Pennisetum purpureum Schum cv. Taiwan,Pennisetum purpureum Schum. cv. Huanan and Pennisetum purpureum × P. typhoideum cv. Reyan. No. 4. The results showed.all of them adapted to the environment of experiment area well. The fresh yield of Penniseturn purpureurn Schurn cv. Taiwan is the best, 141 345. 68 kg/hm^2 the next is Pennisetum purpureum X P. typhoideum cv,Reyan. No. 4,137 798.85 kg/hm^2, （Pennisetum purpureum. cv. Mott） × （P. americanum× P. purureum）]cv. Guimu No. 1,125 322. 6 kg/hm^2, Pennisetum purpureum schumab cv. Red, 119 179. 58 kg/hm^2, the yield of which were respectively higher 31. 87%, 28. 56%, 16. 92%, 11. 19% than that of the Pennisetum purpureum Schum. cv. Huanan, 107 183.55 kg/hm^2,whieh is the control forage. As to other aspects,the Pennisetum purpureurn, cv. Mott have more leaves and higher protein content, which make it suitable to feed small herbivorous,such as rabbits ,fish and goos＇es,and so on. The better production,high yield and high nutrient contents of Pennisetum purpureum Schum cv. Taiwan and Pennisetum purpureum schumab cv. Red are as excellent as that of （Pennisetum purpureum, cv. Mott） × （P. americanum × P. purureum）]cv. Guimu No. 1. Therefore,the Pennisetum purpureum Schum ev. Taiwan and Pennisetum purpureum schumab cv. Red have the potential to be a new kind of forage in the southern part of China,and which could be be applieated and expanded in the future.
