高冰草是山东农科院从澳大利亚引进的优良牧草 ,表现出耐寒、耐旱、耐盐碱、产草量高、品质好、适应性强等优良特性 ,几年来在新疆推广了一定面积。但该草与豆科牧草、农作物混植试验还未见报道。 1993 - 1995年间我们进行了试验 ,结果表明 :高冰草与豆科牧草混播 ,产草量比高冰草单播提高 10 - 2 7% ,增产效果显著。特别是高冰草与红豆草混播试验 ,不浇水 ,依靠自然降水 (该地年降水量 2 5 0 - 3 5 0 mm) ,第三年收鲜草 10 .8T/ ha,适于建立高产人工草场、干旱区草地建植和山地草原改良利用。高冰草与春小麦适量混播 ,对小麦影响小 ,又可多收一茬草 ,这种生产方式对缓解四季草场不平衡、减轻草场负担有一定的意义
Gao Bing Cao is an excellent forage introduced from Australia by Shandong Academy of Agricultural Sciences and shows excellent features such as cold tolerance, drought tolerance, salt tolerance, high grass yield, good quality and strong adaptability. In recent years, it has promoted a certain area in Xinjiang. However, the grass and legumes, crop planting experiments have not been reported. From 1993 to 1995, we carried out the experiment. The results showed that the mixture of high-density grass and leguminous grass increased 10-277% higher than that of unicceed grass, and the yield increase was remarkable. In particular, the experiments of mixed sowing of Agropyron roxburghii and sainfoin grass were carried out without watering and relying on natural precipitation (annual precipitation of 2550-350 mm). In the third year, fresh grass of 10.8 T / ha was harvested and suitable for establishing high yield Artificial grassland, arid grassland and mountain grassland improvement and utilization. The suitable mixed cropping of wheatgrass and spring wheat has little effect on wheat and can take more than one crop of grass. This mode of production has some significance to relieve the imbalance of the pasture and relieve the burden on the grassland
