巨丰谷为中国环科院近年从美国引入的一个新型饲草饲料兼用型品种,我场1988年引进试种获得成功。并广泛推广种植,取得了显著经济效益和社会效益,深受各地区农牧民欢迎。巨丰谷一般株高170—210厘米,叶淡绿色,每株生叶12—18片。分蘖力特强,株分蘗6—8株,每株一穗,穗直立顶端,长80—100厘米,直径2厘米,粒金黄色,特大,是普通谷粒的3—4倍,一般亩产籽实550—1100公斤,亩产饲草2万公斤。该谷营养丰富,据检测,含蛋白质11.2％、糖类68.8％、脂肪3.1％,纤维素8.7％,色氨酸3.1％等,另外体内还含有其它七种微量元素。巨丰谷生育期110天左右,速生、抗旱、抗逆性强,适应性广,全国各地区年积温在2600℃的地方均能种植。对土壤无选择,沙壤土、河坡、山地、平原均可种植,可与禾本科作物套种,也可与林果木间作。抗病性强、耐涝。秸秆可青贮、打浆、青刈饲喂牲 Jufeng Valley for the Chinese Academy of Central ASTRI in recent years from the United States introduced a new type of forage and feed varieties, my field in 1988 to introduce trial success. And extensively popularize the planting. It has achieved remarkable economic and social benefits and is deeply welcomed by farmers and herdsmen in all regions. Jufeng Valley generally 170-210 cm in height, leaves light green, leaves each leaf 12-18. Strong tillering ability, tillers 6-8 plants, each panicle, spike erect top, 80-100 cm long, 2 cm in diameter, golden yellow, extra large, 3-4 times the normal grain, the average per mu Seeds 550-1100 kg, 20,000 kilograms of forage grass per mu. The valley is rich in nutrients, according to the test, with 11.2% protein, 68.8% carbohydrates, fat 3.1%, cellulose 8.7%, tryptophan 3.1%, the other also contains other seven trace elements. Jufeng Valley growth period of about 110 days, fast-growing, drought-resistant, strong resistance, wide adaptability, all regions of the country in 2600 ℃ annual temperature can be planted. No choice of soil, sandy loam, river slopes, mountains, plains can be planted with intercropping gramineous crops, but also intercropping with fruit trees. Disease resistance, waterlogging. Stalks can be silage, beating, green-feeding feeding animals
