| 中文摘要: |
| 为了研究垄沟种植对盐角草(Salicornia-Europaea L.)生长的影响,本研究采用田间试验比较了垄沟种植与常规种植两种模式下,盐角草生长及其矿质元素含量与累积量的差异。结果表明,垄沟种植模式能够增加盐角草地上部与地下部的生物量,提高盐角草的冠根比,尤其是垄上单株生物量约为垄下与常规种植的2倍。垄沟种植能够改变盐角草地上部的矿质元素含量,其中氮钾钠尤为显著。垄上植物地上部的全氮与全钠较常规种植无显著差异,但显著高于垄下;而垄下全钾显著高于垄上与常规。另外垄沟种植模式下,盐角草养分吸收与盐分累积量均高于常规模式。因此,在盐角草种植改良盐渍土方面,配合使用垄沟种植模式将更有利于盐渍土的改良与修复。 |
| 英文摘要: |
| In order to find out the effects of ridge and furrow planting on salt accumulation and growth of Salicornia-Europaea L.，field experiments were conducted to study the growth and contents and accumulative amounts of mineral el-ements of Salicornia Europaea L. under ridge and furrow and conventional flat planting methods. The results indicated that the biomass and shoot/ root ratio of Salicornia Europaea L. increased with ridge and furrow planting. Especially the biomass with ridge and furrow planting was nearly 2 times as that with conventional flat planting. The methods of ridge and furow planting could influence the content of mineral elements of Salicornia Europaea L.，especially that of N，K and Na. There was no significant diference in the content of N and Na of Salcornia Europaea L. between ridge and conventional flat planting， but this was sigmificantly higher than that with furow planting. The content of potassium of Salicornia Europaea L. with furow planting was higher than that with ridge and conventional flat planting. The accumu-lative amounts of mineral elements under ridge and furow planting were significantly higher than those under conventional flat planting. Thus the methods of ridge and furow planting could stimulate Salicornia Europaea L. growth and strength the effectiveness of soil amelioration. |
