  • 简介:硅(Si)经由钙硅酸盐的申请被供应了到植物到土壤;然而,因为它的低溶解度,钙硅酸盐的高剂量被要求。Nanoparticles能减少Si剂量并且被用于播种沟。这研究调查了液体Si来源的效果,即,高度可溶的硅酸盐(115.2gL1Si和60.5gL1Na2O)并且nanosilica(<200nm),在Si上,由米饭的举起种,植物木质化,植物C:N:Pstoichiometry,植物生理学,和谷物在greanhousecondistions下面用Oxisol让步。处理包括了nanosilica和可溶的硅酸盐的申请到在0,605,1210,和2420g的Si剂量播种沟哈1。植物举起和处理效果被测量累积,生理的特征,和谷物米饭产出的C和木质素内容,Si,N,和P评估。在标志叶子的硅石身体和非结晶的硅石的免职用扫描电子显微镜学被分析。液体Si的申请在与控制的关系在米饭增加了Si累积47.3%(0g哈1Si),不管Si,来源使用了。Nanosilica申请增加了叶木质素内容112.7%什么时候与那相比在控制。硅中等影响了网C吸收(增加了1.83%)并且蒸发率(增加了48.3%);然而,Si影响了既不植物生长也不米饭的谷物产量。这些结果被关於生命或不能生活的应力的缺乏在实验期间在米饭植物解释。就我们的知识而言,在巴西农业,这在植物营养上作为Si化肥和它的效果是nanosilica的使用上的第一份报告。这研究提供米饭植物吸收并且积累nanoparticles的证据;然而,进一步的研究被要求在另外的植物种类调查nanoparticles的使用。

  • 简介:干燥播种是一个节省资源的米饭建立方法。与相等的收益,干燥播种充满的米饭(数据设置就绪)为传统的移植充满的米饭(TFR)被看作了代替。然而,在叶的差别和根老朽很少在谷物在数据设置就绪和TFR之间充满期间被识别。在这研究,根长度,根尖端数字和在成熟期间的米饭变化Huanghuazhan和Yangliangyou6的叶老朽在数据设置就绪和TFR之间被比较。结果证明在数据设置就绪的顶三叶子有相对更低的SPAD价值,更低的N内容和早熟的叶老朽的特征。另外,全部的根长度和数据设置就绪的全部的根尖端数字是比TFR的那些显著地低的。在结论,早熟、快的叶老朽在成熟期间与不适当的根长度和根尖端数字被联系,它可能从氮供应的缺乏导致数据设置就绪。改进叶氮地位并且推迟叶老朽在期间上的技术在数据设置就绪充满谷物应该在未来研究被开发。
