我国有较多的低湿地草地资源,这部分草地资源土壤湿润,潜在的肥力较高,一般产草量也较高,但是由于草地严重超载过牧,使这部分草地资源也向退化方向发展。主要表现在牲畜不食的喜湿性植物明显增多,并形成优势群丛,影响草地应发挥的效益。仅我县就有退化的低温草地24万多亩。因此,改良低湿草地对发展畜牧业具有重要意义。而富菜这种植物就是改良低湿草地的一种高产优质牧草。一、富菜的特征富菜(Oenanthe decumbecns(Thunb)K.-Pol.)为伞形花科多年生植物,在载培条件下,株高80～120cm,直立或匍匐,下部具匍枝;匍枝长可达数米,微带紫色,有分枝。叶互生,有柄;叶片三角状阔卵形,2回羽状复叶,裂片卵圆形至菱状披针形,边缘具大小不等的尖齿或钝齿。复伞形花序,花白色,较小;萼5裂,裂片短尖;花瓣5片,基部具短爪;雄蕊5,雌蕊2,子房下位,柱头2歧。双悬果椭圆形或近似圆锥形,萼齿与花柱宿存,果枝隆起,具木栓质。富菜适生于低湿地带,水淹2～3天不死。抗寒性强,在-39.5℃冻不死。在水肥条件好的开旷地上能出1.5～2m高多分枝的大株丛。此草返青早,生长迅速,
There are many lowland wetland resources in our country. The soil resources of this part of grassland are wet, the potential fertility is high, and the yield of grassland is generally high. However, due to serious overloading of grassland, grassland resources are also degraded. Mainly manifested in the livestock did not eat hygroscopic plants significantly increased, and the formation of dominant groups, affecting the grass should play a benefit. Only my county has degraded low temperature grass 240,000 mu. Therefore, improving low-wetland grassland is of great significance to the development of animal husbandry. Rich vegetables, this plant is to improve low-wetland grass a high yield and quality forage. First, the characteristics of rich vegetables Rich vegetables (Oenanthe decumbecns (Thunb) K.-Pol.) Umbelliferae perennials, in the culture conditions, plant height 80 ~ 120cm, upright or prostrate, the lower part of the sticks; creeping; Branch length of up to several meters, purple microstrip, branches. Leaves alternate, sessile; leaf blade triangular-ovate, 2-pinnately compound leaves, lobes ovoid to rhombic-lanceolate, margin with jagged teeth or blunt teeth. Compound umbel, white flowers, smaller; calyx 5-lobed, lobes short; petals 5, base shortly clawed; stamens 5, pistils 2, ovary inferior, stigma 2-branched. Double hanging fruit oval or nearly conical, calyx teeth and style persistent, fruit branch uplift, with cork quality. Rich vegetables suitable for living in low wetlands, flooded 2 to 3 days die. Cold hardiness, not die at -39.5 ℃. Good water and fertilizer conditions in the open area to 1.5 ~ 2m high multi-branched large plant Cong. This grass green early, rapid growth,
