羊草(Aneurolepidium chinensis)以无性繁殖为主,种子结实率低,天然羊草地亩产种子约8—10斤。据我们测定,1克羊草种子450—500粒,其中具胚和胚乳的饱满种子250—280粒,但是田间发芽率仅10—20％。因此生产上迫切需要提高羊草的发芽率,以减少单位面积的播种量,降低生产成本,使苗全、苗壮,增加饲草产量。
Leymus chinensis (Aneurolepidium chinensis) mainly asexual reproduction, seed setting rate is low, natural grasses yield about 8-10 kg per mu. According to our determination, 450-500 seeds of 1 gram of Leymus chinensis seed, including 250-280 full seeds with embryo and endosperm, but the germination rate in the field is only 10-20%. Therefore, the urgent need to improve the production of Leymus chinensis germination rate in order to reduce the sown area per unit area, reduce production costs, so that Miao, Miao Zhuang, increase forage production.
