| 摘 要： | 在土壤条件极为恶劣地区,即全盐量和pH值都超标的恶劣条件下,采用换土、增加有机肥的施用、在种植坑内投放土壤保水剂和高效盐碱土壤改良剂等新技术取得了显著的效果,可使丁香、青皮柳及樟子松等所有供试苗木的成活率都达到和超过铁道部造林标准;造林试验区的土壤全盐量降低0.729个百分点,pH值降低11.31%。

| Abstract: | In the vile condition of soil(total salinity and pH value all went beyond the standard),taking new techniques of adopting soil replacement,adding organic fertilizer application,putting water-holding agent and Alkali-saline soil amendment in pits,the significant effect was got.The survival rate of all experimental seedlings,such as lilac,Pinus sylvestris var.mongolica all reached and exceeded afforestation standard of railway department.Soil total salinity in afforestation test plot decreased by 0.729 percentages and the pH value decreased 11.31%. |
