摘要
在“黑土滩”退化草地补种多年生禾本科牧草后，第２年禾草产量增加明显，第３年达到高峰（鲜草２０６．０ｇ／ｍ２），５年后禾草衰退严重，但草地水土条件得到了改善。嵩草的试种结果表明，其自然发芽率很低，株丛生长极为缓慢，４年的生长仍处于苗期，未形成生殖枝。禾草和嵩草的混合补种是恢复“黑土滩”退化草地植被的理想途径。
After resowing perennial grasses on“Black Soil Patch” ,the grass yield increasedobviouslv in 2nd year,and reached highest(fresh yield was 206.Og/m2)in 3rd year.After 5years,the grasses deteriorated seriously, but water and siol condition of“Black Soil Patch ”grass-land had been improved.The resuIts of seeding KobTeSza showed a low germination percentageand very slow growth.A fter 4 years'growth,Kobresia was still remain at vegetative stage Themlxed resowing of grasses and Kobresia was a ideal measures to reestablish vegetation on “BlackSoil Patch”.
