畜牧业要想持续稳定的发展,必须有雄厚的饲料基础。我国是一个人多地少,人均占有粮低的国家,这就限制了食粮动物的发展。然而我国54亿亩草场资源中有着丰富的野生饲料资源,开发这些资源有着广阔的前景和重要意义,胡枝子就是一种丰富的优质野生饲料资源,很值得开发利用。一、植物学特征胡枝子为豆科Leguminosae。胡枝子属Les-pedeza Michx.胡枝子Lespedeza bicolor Turcz.别名:荻、野花生等。落叶灌木,高0.5～2m。三出复叶,小叶狭卵形,倒卵形或椭圆形。总状花序腋生,成圆锥花序状。花冠紫色。荚果斜倒卵形,有子房柄及短尖。花期7—8月,果期9—10月。二、生态习性及资源分布胡枝子生长于山坡。不论林间、疏林、灌丛草场均有大面积生长。对气候及土壤的适应性很强,喜成片集居。分布我国东北、内蒙古、河北、山东、河 Animal husbandry in order to continue the steady development, there must be a solid feed basis. Our country is a country where there are fewer people and fewer people per capita, which limits the development of food animals. However, 54 million mu grassland resources in our country have abundant wild animal feed resources. The development of these resources has broad prospects and important significance. Lespedeza bicolor is a rich and high-quality wild feed resource, which is worth to develop and utilize. First, botanical characteristics Lespedeza Leguminosae. Lespedeza Michx. Lespedeza bicolor Turcz. Alias: Di, wild peanut and so on. Deciduous shrubs, high 0.5 ~ 2m. Three out of the compound leaves, lobular narrow ovate, obovate or oval. Racemes axillary, panicle-like. Corolla purple. Pod pitted obovate, with ovary and short tits. Flowering from July to August, the fruit period from September to October. Second, ecological habits and resource distribution Lespedeza grow in the hillside. Regardless of forest, sparse forest, shrub grassland have large area growth. Strong adaptability to climate and soil, hi into a film set. Distribution of northeast China, Inner Mongolia, Hebei, Shandong, river
