【摘要】 田间试验表明,燕麦新品种“保罗”在施氮量为90~135 kg/hm2的情况下,其植株鲜草和干草产量随着施氮量的增加而增加;干草中粗蛋白质、全磷、全钙、粗灰分含量随着施氮量的增加而提高,粗纤维含量则随着施氮量的增加而降低。施用氮肥不仅能增加燕麦植株营养体的产量,而且能改善干草的品质。在种植燕麦作为草食牲畜饲料时,为提高植株营养体产量和营养成分,应适当增施氮肥。更多还原

【Abstract】 Field experiment was conducted to investigate the effect of nitrogen application rate on fresh grass yield and quality of oat.The results showed that fresh and dry grass yield of oat "Baoluo" increased with the increment of N application rate from 112.5 to 135 kg/hm2.At the same time,content of crude protein,total phosphorus,total calcium and crude ash in dry grass were improved,but content of crude fibre was decreased.Application of nitrogen fertilizer could not only increase grass yield but also improve quality of dry grass of oat.Increasing N application rate appropriately was necessary to oat cultivation for forage of livestock.更多还原
