概括

堆肥,元素硫 (ES) 和硫纳米粒子 (SNP) 改善了盐土. 将堆肥与SNP相结合最有效地提高了土壤特性和玉米产量,提供了可持续的农业解决方案.

科学领域:

农业科学农业科学
土壤科学土壤科学
环境科学环境科学

背景情况:

土壤盐度是农业生产率的一个主要限制,特别是在干旱和半干旱地区.
高盐度对土壤特性和作物产量产生负面影响,需要有效的管理策略.

研究的目的:

评估堆肥,元素硫 (ES) 和硫纳米颗粒 (SNP) 的有效性,单独或组合,以改善不同盐度下土壤特性和玉米生产率.
测试综合修改 (堆肥+ES或堆肥+SNP) 与单一修改相比提供更优质的好处的假设.

主要方法:

在四个盐度水平 (3.68至12.18dS/m) 的实地研究.
堆肥,ES,SNP,堆肥+ES和堆肥+SNP的应用.
评估土壤属性 (SOM,SAR,pH,含量,透率,多孔性) 和玉米性能 (谷物产量,草产量,植物高度,长,叶绿素含量).

主要成果:

肥料单独增加了土壤有机物质 (SOM) 的1.33倍,并减少了33%的吸附比率 (SAR),在中等盐分的土壤中提高了40%的产量.
ES和SNP将土壤pH值降低了0.8-1.2单位,的可用性增加了25-30%.
堆肥-SNP组合显示出最显著的改善,在高度盐分的土壤中,透率提高了60%,毛孔性增加了15%,草产量增加了50%,植物高度,长和叶绿素含量显著增加.

结论:

用ES或SNP集成应用堆肥在改善土壤盐度压力方面非常有效.
堆肥-SNP组合为改善盐水环境中的土壤质量和玉米生产率提供了一个有希望的策略.
这些发现支持盐受影响地区的可持续农业实践.

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
