概括
尿素深部放置 (UDP) 和综合植物营养系统 (IPNS) 显著提高了大米产量和使用效率 (NUE). 在交替灌和干燥 (AWD) 灌下将UDP与家禽垃圾 (PL) 结合起来,显示出对作物生产率和土壤健康有希望的结果.
科学领域:
- 农业科学 农业科学
- 农业学是一种农业学.
- 土壤科学 土壤科学
背景情况:
- 使用有机和无机投入物优化肥料管理对于提高大米产量和土壤健康至关重要.
- 关于综合植物营养系统 (IPNS) 的研究有限,这些系统结合了尿素深部放置 (UDP) 或广播尿素 (PU) 与有机输入 (家禽垃圾 [PL],虫堆肥 [VC]) 在替代湿干 (AWD) 灌下.
研究的目的:
- 调查不同肥料处理 (控制,PU,UDP和IPNS) 和灌制度 (AWD,连续洪水 (CF)) 对大米产量和使用效率 (NUE) 的影响.
主要方法:
- 实地实验在干旱和潮湿季节进行了三年 (2018-2020年).
- 处理包括对照,广播尿素 (PU),尿素深部放置 (UDP) 和IPNS (PU + 虫 [VC],PU + 家禽垃圾 [PL],UDP + PL).
- 灌制度是交替湿和干 (AWD) 和连续洪水 (CF).
主要成果:
- 肥料处理和灌制度显著相互作用 (p < 0.05),影响干旱季节的米产量和气农业效率 (AEN).
- 与广播PU相比,UDP在两个季节都显著增加了大米产量,总干物质 (TDM) 和NUE.
- 与PL作为IPNS相结合的UDP显著提高了大米产量,TDM和NUE,而不是广播PU.
- 在AWD下,UDP单独的产量高于其他治疗方法;在CF下,UDP和UDP + PL的产量相似.
- 在干旱季节,AWD灌显著增加了大米产量,TDM和AEN,在雨季,产量和NUE与CF相比相当.
结论:
- 尿素深度放置 (UDP) 单独或与家禽垃圾 (PL) 集成为IPNS提供了一种可行的策略,以提高大米生产率.
- 这些方法有助于提高利用效率 (NUE) 和保持土壤肥力.
- 替代湿干 (AWD) 灌,特别是UDP灌,显示了优化水和营养管理在水种植的潜力.

Key Elements for Plant Nutrition
18.8K
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...

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.
