达乌里胡枝子在科尔沁沙地播种当年即能形成种子 ,第二年返青较早 ;成熟枝条长达80 .1cm ,每株分枝可达 8～ 11个 ,枝条基部可产生不定根 ;单株地上生物量 2 0 .73～ 4 2 .76 g ,枝叶比较高 ,可达 1∶ 1.2 2 ;第二年鲜、干草及种子产量分别为 156 0 7.81kg/hm2 、6 151.36kg/hm2 和4 2 6 .2 1kg/hm2 ,再生性较好 ,但早利用会使总产量降低 ;达乌里胡枝子根系发达 ,生长 50d入土深达30cm ,10 0d后深达 50cm ,生长 2年后达 10 0cm ,多年野生植株根系可达 140cm ,水平根也较发达。
Dalu Lespedeza in Horqin sandy land sowing that seeds can be formed, the second year back to green earlier; mature branches up to 80.1cm, each branch up to 8 to 11, branches can produce adventitious roots; single plant Above-ground biomass ranged from 20.73 to 42.276 g, with relatively high branches and leaves up to 1: 1.2 2. In the second year, fresh, hay and seed yields were 156 0 7.81 kg / hm 2 and 6 151.36 kg / hm 2, respectively 2 6 .2 1kg / hm2, better regeneration, but the early use will reduce the total output; root growth of dahuriensis branch developed 50d deep into the soil depth of 30cm, 10d after the depth of 50cm, after 2 years of growth up to 10 0cm, for many years the roots of wild plants up to 140cm, the level of roots are also more developed.
