概括
土壤修改 (SA) 降低小麦粒中的,提高有益矿物质,但可以减少必需矿物质. 特定的小麦品种显示出平衡安全,营养和受污染的土地上的产量.
科学领域:
- 农业科学 农业科学
- 环境科学 环境科学
- 食品科学 食品科学 食品科学
背景情况:
- 土壤修饰 (SA) 和低积累品种是使用Cd污染土地的策略.
- 关于SA对各种小麦品种的Cd缓解和营养质量影响的数据有限.
研究的目的:
- 评估SA对12种小麦品种的农学特征,Cd积累,转移和矿物营养的影响.
- 确定在Cd污染的酸性田地中平衡食品安全,营养质量和产量的小麦品种.
主要方法:
- 在酸性土壤中对12种小麦品种进行实地实验 (0.46 mg/kg Cd).
- 评估土壤DTPA Cd,小麦的农学特征,谷物Cd度和矿物元素度 (有益和必不可少).
主要成果:
- SA显著降低了土壤DTPA Cd (42.3%) 和谷物Cd (61.65%),但谷物产量略有下降 (平均值). 7.62%).这是一个很好的例子.
- 酸盐增加了有益的元素 (Mo,Se),但减少了小麦谷物和内中的必需矿物质 (Ca,Fe,Mn).
- 观察到基因型差异,鉴定出华迈33种,珍迈168种,苏迈188种和扬迈28种是有前途的品种.
结论:

02:35Key Elements for Plant Nutrition
18.7K
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...

02:11The Roles of Bacteria and Fungi in Plant Nutrition
35.3K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
