| 摘 要： | 在新疆南疆重盐化土壤上采用田间试验方法及完全随机区组设计,研究了不同氮肥施用水平(0、75、150和225 kg/hm2)对盐角草生长以及矿质灰分吸收累积的影响.结果表明,施用氮肥能显著提高盐角草的地上部各部分生物量、根系干重、种子产量及总灰分累积量,其中施用225 kg/hm2氮肥时,盐角草每年可从土壤中带走8 43...

| Abstract: | Research was carried out in the hope of restoring the saline land rapidly and effectively through improving halophytes'biomass and performance by applying nitrogen fertilizer in saline areas.Effects of various levels of nitrogen fertilization(0,75,150 and 225 kg/hm2) on growth,mineral ash absorption and accumulation of Salicornia europaea L.were studied through complete randomized block design under the saline field condition in Xinjiang.The results indicated that the aerial biomass,the root dry weight,the ... |
