根际根际rhizosphere根际中的氮素.主要是当季新加入的钱态氮肥料，呈现亏缺梯度;而全氮的差异不显著。不论是硫按、碳按和尿素，离根1毫米的上壤中亏缺率可达30%~70%，并随离根表面的距离呈指数曲线的变化。亏缺范围在10毫米以内梯度最大，表明这一范围是氮素供应的主要部位。旱作与水稻亏缺曲线上有所不同，NH4一N在根际的最大亏缺区处于离根1~2毫米之外，0~2毫米内存在相对累积区(图7)。近根的这种相对累积，经证明是由于根系向外溢泌的分泌物中含有的氮，以及根毛等脱落组织所产生的结果。而水稻的分泌物和脱落物均低于旱作，因而这种根周围相对累积现象不明显。离根面距离(nlnl)10 20 30 40才产.一NH;，2 50:NHZ，2 CO 10 2(J30︵欲)辞岌归之，霍即(a)水相离根面解卜离(.llnl-《b、玉米图7两种NH丁一N月巴料在作物根际土壤中的分布情况有效磷的亏缺仅限于离根1毫米左右，相当于根毛长度。在砂性土壤上亏缺范围可扩展到4毫米以内。磷亏缺的范围很窄的原因是与它在土壤中有效扩散系数很小有关，通常为10~’~1。”’厘米/(厘米，·秒)。显然，仅仅依靠土壤中有效磷径向扩散以供应根系吸收是难以满足需要的。而依靠新生根的伸展不断获取根附近新土区中的磷则是主要的途径。钾的梯度变化类似于按态氮，但亏缺范围比后者要小，通常在离根8~10毫米的范围内.代换性钾和迟效性钾(l摩尔/升HCI提取)有类似的亏缺趋势。但是，在土壤水分含量较高时有效钾在根际可出现相反的向根富集的现象。有效性锰、锌和硅通常也在根际出现亏缺。硼和钥在根际的含量变化取决于它们在t壤溶液中的浓度。浓度低时可出现亏缺，浓度高时则累积.根际亏缺梯度的存在有利于七壤养分向根扩散。但是，亏缺量过大时则影响根系的吸收。土壤溶液中N〔)了、S()军一、CaZ十、MgZ’等含量相对较大。因此，这些养分通常作为溶质随着植物蒸腾流的水势差向根迁移，即质流过程。通过这种过程流向根表面的量一般是供大于求，由此而出现顺浓度梯度，累积率可达10%~30%，但梯度存在的范围很窄.通常不超过5毫米。有机物根际土壤中有机碳含量比原上体明显增加。其来源主要是根系分泌物，这些物质在化学卜具有多样性.从简单的低分子量的有机酸、糖、氨基酸，到复杂的维生素和植物激素;还有大分子的多种碳水化合物、肤和蛋白质，以及根组织的脱落物等等。这些有机碳约占光合产物的30%左右。此外，微生物在根际的迭代更新，残体的生物量也大大超过原1:体，成为根际有机物质的上要组成成分。
