| 摘 要： | 通过增施氮磷肥提高盐生植物生物量与盐分含量以实现盐分的高吸收累积对重盐渍化地区生态恢复意义重大.基于此,本研究在新疆南疆重盐化土壤上采用田间试验方法就不同氮磷施用水平对盐角草生长以及盐分吸收累积的影响进行了探讨.结果表明,施氮能显著提高盐角草的生物量、种子产量、各盐分离子累积量及全盐累积量,其中施225 kg/hm2氮...

| Abstract: | Research is driven by the hope of rapidly restoring saline land effectively through improving halophyte biomass and performance in saline areas.The effects of varying levels of N fertilization(0,75,150,and 225 kg/ha),and P fertilization(0 and 135 kg/ha) on growth and salt accumulation of Salicornia europaea was studied under field saline conditions in Xinjiang.The aerial biomass,root biomass,seed yield,and salt accumulation increased dramatically with increased N levels.The largest amount of salt absorbed a... |
