冬牧70黑麦草营养价值高,青绿多汁,适口性好。风干后,粗蛋白含量为15—19％,还含有大量的铜、锌、锰等微量元素和胡萝卜素、维生素A等。抗寒性强,播期可晚至下霜前,也获较好的收成,冬前分孽5—7个。喜肥水,抗病性强。较冬小麦耐寒、耐旱、耐瘠薄、分孽力强,抗病虫害力强。试种未见白粉病、叶锈病等。发育早、早春生长快,产量高。在唐山一带3月初返青,平均日增高2cm,4月底收割可达150cm左右。成熟期株高1.8m。在丰润试种,亩产种籽200kg,产鲜草2500—
Winter grazing 70 ryegrass high nutritional value, green and juicy, palatability good. After drying, the crude protein content of 15-19%, also contains a lot of trace elements such as copper, zinc, manganese and carotene, vitamin A and so on. Cold hardiness, sowing date can be late frost, but also get a better harvest, before the winter sub-sin 5-7 months. Hi fertilizer, disease resistance. Compared with winter wheat, it is hardy, drought-tolerant and barren-resistant, it has strong ability of detriment and pest resistance. No species of powdery mildew, leaf rust and so on. Early development, rapid growth in early spring, high yield. In early March, Tangshan area turned green, with an average daily increase of 2cm and a harvest of 150cm at the end of April. Mature height of 1.8m. In the rich run test, yield 200kg per mu, fresh produce 2500-
