| Abstract: | Wild Stipa penicillata was cultivated and the growth characteristics were observed for 6 years in Dawu with altitude of 3756 m.The result showed that the cultivated S.penicillata reproduced mainly by clone in first year,and the overwinter rate were 98% in the next year with 136 days growth period.The overwinter rate was 98% in third year and the phonological phase was 4 to 10 days ahead compared to that in second year with 125 days growth period.There was a linear grow trend in growth period,the growth rate was the highest in jointing stage and heading stage.The fresh matter yield,dry matter yield and seed yield were 1 160 g/m2,516.2 g/m2 and 8.6 g/m2 respectively,and leaf-stem ratio was 1∶0.46.The coverage was 98% in the third late August,and the relevant yields were 1 160 g/m2,516.2 g/m2 and 8.6 g/m2 respectively.The seed yield in second year was 5 times than that in third year.S.penicillata was an ecotype grass with the characteristics of high stress resistance,early re-greening,more tillers,high productivity and easy to be cultivated and showed a good adaptability. |
