| 摘 要： | 通过贸易购买方式从美国引进优良牧草－多年生香豌豆，在黄土高原地区进行引种栽培试验。多年生香豌豆引种后的适应性很强，适生中心区为黄土高塬沟壑区、黄土丘陵沟壑区一副区、二副区、三副区和冲积平原区；一般适生区为黄土丘陵沟壑区四副区、五副区；适生边缘区为黄土丘陵沟壑区五副区。其生长迅速，产草量很高，产草量鲜重可达80t/hm^2，为紫花苜蓿的2倍以上；生态经济利用价值很高，粗蛋白含量为27．92％，粗脂肪为3．16％，适口性好；枝叶氮、磷、钾含量高，特别是通过其根瘤的固氮作用，可以很好地促进与其间作的林木快速生长；草层茂密，根系发达，水土保持作用很好；栽培技术简便易行，在饲料、园林以及水土保持等方面具有广阔的推广前景。 |

| Abstract: | Perennial pea ( Lathyrus latifolius ) has a good adaptability in the Loess Plateau after introduction from USA. The loess platform and gully region, subregion 1,2,3 of the hilly and gully region, and the alluvial plains are the most suitable center of its growth, then come the subregion 4 and 5 of the hilly and gully region. It grows rapidly and the grass yields get to 80t/hm 2 which are 2 times as highly as that of alfalfa. It has a high ecoeconomic values as its coarse protein is 27.92% and the coarse fat 3.16% which is very suitable for the livestock. Also it has a high contents of nitrogen, phosphorus, potassium in its braches and leaves, and can promote the growth of other mixed trees through its roles of nitrogen fixation. It preserves surface soil well through its thick grass layers and strong roots. It is easy to plant and cultivate the plant in the introduction areas. Perennial pea is a very good multipurpose introduction plant in the Loess Plateau, and has a wide and bright dissemination future in forage, gardening, and soil and water conservation aspects. |
