通过对已出苗皇草种根带老蔸和不带老蔸,每窝一、二、三苗及不同月份每窝二苗以及未出苗老蔸繁殖的成活率和分蘖数的研究,结果表明:不带老蔸种根成活率三苗最高为94.7% ,一苗最低为54.0% ,繁殖系数二苗最高为374.3% ,三苗分蘖最高为11.0;带老蔸种根的成活率一苗为97.3% ,二苗和三苗均为100% ,繁殖系数一苗最高为788.3% ,三苗分蘖最高为15.3。不同月份中的种根繁殖系数4～6 月较高,分别为374.3% ,396.6% 和494.7% ,其中6 月最高。出苗前的皇草种根繁殖,成活率稍低为75.0% ,分蘖数较多为9.2。
Through the study on the survival rate and tiller number of the seedlings of the old seedlings with and without the larvae of the seedlings of the old emperor Kushayera, one, two and three seedlings in each litter and two seedlings in each litter and no emergence in the old seedlings, the results showed that: The survival rate of three kinds of seedlings without the old seedlings was 94.7%, the lowest one was 54.0%, the highest seedling coefficient was 374.3% and the highest was 11.0. The survival rate of the old seedlings with one seedling was 97.3%, two seedlings and three seedlings were 100%, the maximum propagation coefficient of a seedling is 788.3%, three seedling tillers up to 15.3. The root propagation coefficients of different months were higher from April to June, with 374.3%, 396.6% and 494.7% respectively, the highest in June. Pre-emergence of the species of imperial grass breeding, a slightly lower survival rate of 75.0%, tillering number is 9.2.
