摘　　要：试验在营口市引种新型稗谷牧草,通过牧草种子检测试验、物候期观察研究牧草引种适应性。通过不同播种量(800、1 000、1 200、1 400 g/667 m^(2))小区试验测产评价牧草产量。结果显示,牧草种子发芽率达67.69%,生育期134~136 d。1组干草总产量达1.37 kg/m^(2),显著高于2组和4组(P<0.05);播种量800 g/667 m^(2)时产草量较高、茎叶比较低;灌溉组干草产量比不灌溉高0.21 kg/m^(2)。研究表明,新型稗谷牧草在营口地区种植适应性好,最适播种量为800 g/667 m^(2),灌溉能够明显提高产草量,新型稗谷牧草可以作为反刍动物优质牧草资源。The study was to introduce new barnyard millet herbage in Yingkou, and studied the adaptability of herbage introduction through seed testing and phenological observation. The forage yield was measured and evaluated in plots with different sowing rates(800, 1 000, 1 200, 1 400 g/667 m^(2)). The results showed that germination rate was 67.69%, and growth period was 134~136 d. Total hay yield of group 1 was 1.37 kg/m^(2), which was significantly higher than group 2 and group 4(P<0.05), 0.21 kg/m^(2)hay in irrigated groups was higher than no-irrigated. The experiment indicates that the new barnyard grass can be planted in Yingkou, the suitable seeding amount was 800 g/667 m^(2). New barnyard grass can be developed using as high quality roughage in ruminant production.
