有机肥替代化肥和施用硝化抑制剂是提升肥料利用效率、消减施肥所致环境问题的重要途径.201.、2020年针对甘薯(Ipomoea batatas(L.)Lam.)小麦(Triticum aestivum L.)种植体系,设置不施肥(CK)、常规施用化肥(NPK)、单施有机肥(M)、减量施氮+有机肥(80%N+M)、减量施氮+有机肥+硝化抑制剂(80%N+M+NI)和减量施氮+硝化抑制剂(80%N+NI)6个处理,通过田间试验研究减量氮肥配施有机肥及硝化抑制剂对土壤pH值、甘薯产量及构成的影响.结果发现,与NPK处理相比:采用M、80%N+M、80%N+M+NI和80%N+NI 4种施肥处理方式2年,土壤pH值升高0.1.~0.34;所有有机肥施用处理(M、80%N+M、80%N+M+NI)下的甘薯产量均无显著变化(P>0.05);在2020年,80%N+M处理下的甘薯T/R值降低明显,80%N+M、80%N+M+NI处理平均薯块质量分别增加21.8%、1..7%;仅减量施氮配施硝化抑制剂处理下的甘薯产量及大薯(>250 g)比例显著降低(P<0.05).可见,在甘薯小麦种植体系下,减量氮肥下配施有机肥或者配施有机肥和硝化抑制剂,可显著减缓氮肥施用导致的土壤酸化进程,且有利于甘薯薯块膨大.

对于开阔大洋海山结壳的矿物组成和地球化学特征研究已经比较深入,但对边缘海海山铁锰结壳的研究却较少。以在南海东部管事海山上采集的两块铁锰结壳为研究材料,对其进行了X射线衍射、扫描电镜及电子探针微区的分析,结果显示结壳矿物以水羟锰矿为主,含有少量针铁矿,碎屑矿物主要是石英和长石。结壳的显微结构呈现条带状分布,有1.~1.μm长的空隙和0.5μm直径大小的孔洞。相对于大洋结壳,结壳的Mn含量较高,与马尼拉海沟附近火山喷发物质有关,但Cu、Co和Ni含量更低,可能与边缘海沉积速率高或有机络合物吸附有关。矿物组成及元素比值表明结壳主要是水成的,但未发生明显磷酸盐化作用。元素比值和相关性表明,Mn主要来源于南海扩张停止后火山喷发、玄武岩风化形成溶解Mn;Fe与Si元素均来自火山碎屑、生源物质和陆源物质,还受到管状蠕虫吸附的影响。南海管事海山结壳是在富氧环境中上升流作用下选择性吸附水体中溶解化学元素缓慢沉积而成。结壳中元素含量随时间变化趋势反映了南海的古环境变化。
