苏丹草原产非洲。在欧洲,北美洲及亚洲大陆的热带和亚热带地区也有种植。具有根系发达、分蘖及再生能力强、产量高、营养丰富的特点,在我国南方淡水养鱼地区得以广泛种植和应用。湖北是淡水养鱼大省,常年种植作鱼用饲料作物120万余667m2,其中种植面积最大的是苏丹草。然而影响苏丹草产量和品质最大的因素就是杂草。为了有效地铲除这一障碍因素,在苏丹草种植展开了研究,取得了丰硕成果。
Sudan grassland origin Africa. In Europe, North America and Asian continents are also planted in tropical and subtropical regions. With developed roots, tillers and regeneration ability, high yield, nutrient-rich features in southern freshwater fish farming areas to be widely planted and applied. Hubei is a major freshwater fish farming province, planting perennial fish crops for more than 1.2 million 667m2, of which the largest plantation area is Sudan grass. However, the most important factor affecting Sudan’s grass yield and quality is weeds. In order to eradicate this obstacle effectively, research has been carried out on the cultivation of sudangrass and great achievements have been made.
