Carbon neutrality of the steel industry requires the development of high-strength steel. The mechanical properties of low-alloy steel can be considerably improved at a low cost by adding a small amount of titanium (Ti) element, namely Ti microalloying, wh
Alloys designed with the traditional trial and error method have encountered several problems, such as long trial cycles and high costs. The rapid development of big data and artificial intelligence provides a new path for the efficient development of met
Greenhouse gas (GHG) emissions related to human activities have significantly caused climate change since the Industrial Revolu-tion. China aims to achieve its carbon emission peak before 2030 and carbon neutrality before 2060. Accordingly, this paper rev
Failure of the zirconium alloy claddings due to iodine-induced stress corrosion cracking (I-SCC) will increase the risk of fission product leakage. The progress of I-SCC has been comprehensively investigated in a massive amount of published literature. Fo
本文简要介绍睢宁县2019年以来推进农作物病虫害绿色防控工作的主要做法与成效,建议建立健全财政补贴机制、发挥政府与市场的协同作用,积极打造绿色产业链、增强品牌效应,扩大绿色农产品销路,通过“政府扶持+市场拉动”,鼓励、引导生产者自觉采用绿色防控技术.

2021年,睢宁县玉米锈病偏重发生,发病面积达1.41万hm2,表现为发病急、发生程度重、发生面积大、品种间抗病性差异明显等特点,原因主要是种植密度大、气候条件不利、玉米品种抗病性差等.本文针对性提出了通过科学管理、选用抗病品种、发病初期及时喷药等防控策略.
由于受到种植制度不科学、连续多年在同一个地块种植玉米等因素的影响,玉米病虫害呈现加重流行的态势.本文结合实际工作,对玉米种植中常见病虫害的防治措施进行了探讨,希望对同行有所帮助.
