| 摘 要： | 通过田间试验,研究了重度苏打盐碱荒地施用脱硫石膏、国产1号和国产2号3种盐碱地改良剂对紫花苜蓿出苗率和鲜草产量的影响。结果表明,与不施土壤改良剂(对照)相比,施用3种盐碱地改良剂的土壤(0～20 cm)pH值降低0.15～1.26,紫花苜蓿出苗率提高17.8%～30.5%,提高出苗率由大到小的顺序为脱硫石膏>国产2号>国产1号;鲜草总产量增加3 107.5～6 971.3 kg/hm2,促进鲜草产量增加由大到小的顺序为国产2号>国产1号>脱硫石膏。

| Abstract: | The experiment was conducted to investigate the effects of Desulfurized gypsum,Guochan 1,Guochan 2 conditioners on yield of alfalfa in the waste saline-alkali soil with heavy soda under field conditions.The results showed that,compared with the control,soil pH reduced 0.15～1.26,the emergence rate of alfalfa increased from 17.8% to 30.5% after application of three soil conditioners.The order of increasing emergence rate was Desulfurized gypsum > Guochan 2> Guochan 1.The total fresh biomass of alfalfa were increased by 3 107.5～6 971.3 kg/hm2,and the order of enhancing fresh biomass was Guochan 2 > Guochan 1 > Desulfurized gypsum. |
