Abstract

Physiological structures, components and elements are critical for cultivating a healthy crop. The use of alternative products to promote plant growth and health is required for a growing demand. Leaf chlorophyll concentration, chloroplast ultrastructure as well as element concentration in the shoots and roots of maize treated with industrial by-products were investigated. These included flue gas powder, extruded poppy-heads, grinding sludge and sewage sludge compost. Plants treated with flue gas powder had severe reduction in shoot and root dry weight, chlorophyll content and chloroplast number as well as disintegration of the chloroplasts. Grinding sludge induced the highest root dry weight with the least reduction in shoot dry weight. In addition, the content of various photosynthesis pigments was the highest in the grinding sludge treatment. Furthermore, chloroplasts were intact and cells retained greater endoplasmic reticulum. Sewage sludge compost performed second best after grinding sludge. This study indicates that not all industrial waste materials can be recycled in agriculture due to their negative effects on plant physiology. Flue gas powder cannot be recommended for maize production under presented circumstance to improve production but grinding sludge holds potential. This study contributes to the potential solutions for the disposal of industrial by-products in the landfills.

四种工业副产物对玉米光合色素、干重和超微结构的影响。

摘要

生理结构、成分和元素对于培育健康作物至关重要。不断增长的需求需要使用替代产品来促进植物生长和健康。研究了用工业副产品处理的玉米的芽和根中的叶叶绿素浓度、叶绿体超微结构以及元素浓度。这些包括烟气粉末、挤压罂粟头、研磨污泥和污水污泥堆肥。用烟气粉末处理的植物的地上部和根干重、叶绿素含量和叶绿体数量以及叶绿体的分解严重减少。研磨污泥诱导的根干重最高，而地上部干重减少最少。此外，各种光合色素在研磨污泥处理中的含量最高。此外，叶绿体是完整的，细胞保留了更大的内质网。污水污泥堆肥的表现仅次于研磨污泥。这项研究表明，并非所有的工业废料都可以在农业中回收利用，因为它们对植物生理有负面影响。在目前的情况下，不建议将烟气粉用于玉米生产以提高产量，但研磨污泥具有潜力。这项研究有助于在垃圾填埋场处理工业副产品的潜在解决方案。在目前的情况下，不建议将烟气粉用于玉米生产以提高产量，但研磨污泥具有潜力。这项研究有助于在垃圾填埋场处理工业副产品的潜在解决方案。在目前的情况下，不建议将烟气粉用于玉米生产以提高产量，但研磨污泥具有潜力。这项研究有助于在垃圾填埋场处理工业副产品的潜在解决方案。
