红花岩黄芪是多年生豆科牧草,为岩黄芪属,在永昌半荒漠草场上可见,在西北都有所分布。抗寒性及抗旱性强,适于在棕钙土地带的盐碱草场上根生繁殖。根系非常发达,主根入土深2米左右,65%侧根分布在耕作层内。主根长,根茎入土深。春、夏、秋均可播种。播种当年生长发育缓慢,生活第二年可开花,生活条件适宜时可少量结籽。第三年生长更为强烈。生殖枝由茎基部上4—5节处叶腋产生,侧枝生无限头状花序。节间继续生长,节数增加,并出现新的头状花序。因此在开花的同时形成丰富的青饲料。花色艳丽,可供观赏。属蜜源植物。花期50—70天,种子成熟不尽一致,且落粒性强。分蘖性能较好,其分蘖秋季由距表土1—2厘米根茎发生,分蘖的同时在短主茎的叶腋里形成构成翌年草层的胚茎,这些胚茎到翌年开始生长。牧草适口性好,营养丰富,草质优良,叶产量高于茎,草种兼牧,是很有栽培发展前途的野生优良牧草。 Safflower rock Astragalus is a perennial legume forage, Astragalus, visible in Yongchang semi desert grassland, are distributed in the northwest. Cold hardiness and drought resistance, suitable for breeding in saline-alkali grassland in brown soil zone. Root system is very developed, the main root into the soil about 2 meters deep, 65% lateral root distribution within the tillage layer. Main root length, root deep into the soil. Spring, summer, autumn can be sown. Sowing the slow growth of the year, the second year of life can flowering, living conditions suitable for a small amount of seed. The third year of growth is even more intense. Reproductive branches from the base of the stem 4-5 at the leaf axils generated, lateral branches of infinite head-shaped inflorescence. Internodes continue to grow, the number of sections increases, and new flower heads appear. Therefore, the flowering at the same time the formation of rich green feed. Beautiful color, for viewing. Is a nectar plant. Flowering 50-70 days, seeds are not mature, and the droplet strong. The tillering performance is good, the tillering fall from 1-2 cm rhizome from topsoil, tillering at the same time in the leaf axils of the short main stem to form the embryo stem of the next year grass layer, these embryo stems to grow the following year. Forage palatability, nutrient-rich, excellent grass quality, leaf yield higher than the stems, grasses and husbandry, is a promising cultivation of good wild pasture.
