甜高粱[Sorghum bicolor (L.)Moench]在我国有着悠久的栽培历史,但它却是新兴的糖料作物、能源作物和优良的饲料作物。中国科学院植物研究所北京植物园,于1974年从美国引进甜高粱品种“丽欧”和“洛马”的种子,1975年与河北省科委和河南省科委协作进行示范推广试验。由于甜高粱品种“丽欧”具有适应性强、抗旱、耐涝、耐盐碱、对土壤肥料的要求不高和粮糖双收等优点,因而得到迅速的发展。1978年,天津市工农联盟农牧场开始用甜高粱“丽欧”作为饲料作物栽培,获得了很高的经济效益,天津、北京、河南的试验表明,“丽欧”青贮饲料的产量比玉米高1—2倍,仅天津、北
Sweet sorghum [Sorghum bicolor (L.) Moench] has a long history of cultivation in our country, but it is an emerging sugar crop, energy crop and good forage crop. Institute of Botany, Chinese Academy of Sciences Beijing Botanical Garden, introduced from the United States in 1974 the sweet sorghum varieties “Laiou” and “Loma” seeds in 1975 with the Hebei Provincial Science and Technology Commission and Henan Provincial Science and Technology Commission collaboration demonstration demonstration. Sweet sorghum variety Liou has developed rapidly due to its advantages of adaptability, drought resistance, waterlogging resistance, salt tolerance, low requirement for soil and fertilizer, and double sugar content. In 1978, the farm and ranch of Tianjin Federation of Workers and Peasants started to cultivate the sweet sorghum “Laiou” as a feed crop and obtained high economic benefits. The tests in Tianjin, Beijing and Henan showed that the yield of “Liou” silage was lower than that of corn 1-2 times higher, only Tianjin, North
