科学领域:

农业科学农业科学
植物营养植物营养
食品科学食品科学食品科学

背景情况:

全球 (Zn),铁 (Fe) 和 (Se) 营养不良是一个重大的公共卫生问题.
基于肥料的生物强化提出了一项战略,旨在提高玉米等主食作物的营养质量.
了解不同应用方法和来源的有效性对于有效的生物强化至关重要.

研究的目的:

研究叶子处理对玉米粒中Zn,Fe,Se和N度的影响.
为了比较各种来源的有效性,包括纳米颗粒和常规盐,用于生物强化.
评估叶子应用对Zn和Fe的生物可用性及其与谷物产量的关系的影响.

主要方法:

实地实验在三个地点进行,使用了三种玉米品种.
叶子处理包括氧化纳米颗粒 (ZnO-NPs),Zn-Chitosan纳米颗粒 (Zn-CNPs),常规硫酸 (ZnSO4) 和营养尾酒 (Zn,Fe,Se),所有这些都用尿素涂抹.
分析了谷物营养度,植物酸水平和谷物产量.

主要成果:

在叶子上应用尾酒溶液有效地同时增加了Zn,Fe,Se和N的谷物度,而不会降低产量.
传统的ZnSO4在提高谷物Zn度方面比纳米粒子配方更有效.
谷物营养度的最大增加是在谷物产量最低的玉米品种中观察到的,而植物酸水平下降,提高了Zn和Fe的生物可用性.

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...

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
