摘要
在甘南碌曲海拔3500m草地区建立试验基地,通过对混播(燕麦+春箭豌豆)草地进行不同肥料、施肥量对比试验,结果表明:该地域适当施用羊粪肥和尿素对提高草地产草量效果非常显著(P<0 01),每公顷施羊粪肥15000kg、尿素150kg,可使人工草地产草量分别比对照提高166 7%和98 1%,生产中应大力推广。
Different fertilizer treatments were carried out to test their effects on mixed grassland (oat+ spring vetch) yield in Luqu, Gannan Autonomous Region, where the elevation is around 3 500 m above sea level The result of different kinds of fertilizer and different rate treatments shows that the fresh yield can be significantly increased 1667% and 981% than control by applying 15 000 kg /hm2 sheep manure and 150 kg/hm2 urea, respectively
