本文研究了温度、水分、光照、贮存年限和土壤盐分对种子萌发的影响。确定了该草的最佳播种条件和播种方法。结果表明,在温度为2℃、土壤含水量为10％、Na_2SO_4含量的2％、NaCl和混合盐含量为1.5％的不良条件下也可以发芽,但发芽率很低,最适发芽条件是:温度为12～20℃,土下播种含水量为18％,地表播种含水量为28％,Na_2SO_4含量为0.5％～1％,NaCl和混合盐含量为0.2％。该草种子没有休眠期,种子寿命为三年,最适贮存年限为一年。
In this paper, the effects of temperature, moisture, light, shelf life and soil salinity on seed germination were studied. The best sowing conditions and sowing methods were determined. The results showed that under the adverse conditions of temperature 2 ℃, soil moisture 10%, Na 2 SO 4 2%, NaCl and mixed salt 1.5%, the germination rate was very low. The optimal germination conditions were as follows: The temperature was 12 ~ 20 ℃, the sowing moisture under soil was 18%, the surface sowing water content was 28%, Na_2SO_4 content was 0.5% ~ 1%, NaCl and mixed salt content was 0.2%. The grass seeds have no dormancy, seed life of three years, the optimum storage period of one year.
