在对技术进行理论溯源与发展嬗变分析的基础上,研究技术的二律背反特性,提出技术具身与技术理性价值取向对职业教育带来多元影响、技术文化融入主流文化速度缓慢导致职业教育发展中的技术意识淡薄现象更严重、技术哲学的发展滞后使得技术研究面临诸多困难等理论观点。在经济社会全面数字化、智能化的当代背景下,发挥技术对职业教育的反向规约力,以技术内化的方式丰富和发展职业教育实践的新形态,真正发挥技术向善的正向作用,应该运用技术伦理来对职业教育中狭隘的技术向度和利益局限进行纠偏和矫正,不断加强对技术的理论研究与实践探索。

了解葡萄种植集聚区土壤肥力特征是有效制定土壤与精准施肥管理措施的重要前提。本研究选取苏北灌南县为研究对象,对55家设施葡萄园非施肥区和施肥区土壤主要肥力指标进行了测定,运用主成分分析与隶属度函数相结合的模糊综合评价法,对土壤肥力特征进行了综合分析与评价。结果表明,葡萄园施肥区土壤综合肥力整体处于较高水平,其中有机质和全氮的指标权重最大,分别为18.98%和18.02%,是影响葡萄园土壤肥力的关键因子。与非施肥区土壤相比,施肥区有14.55%和10.91%的土壤分别存在有机质和全氮含量降低现象。研究区土壤pH均呈碱性,是限制土壤肥力的主要因子。葡萄园本底有效磷含量普遍偏低,均值为19.51 mg·kg^(-1),而速效钾、交换性钙、交换性镁含量均处于较高水平,均值分别为364.55、12346.52 mg·kg^(-1)和816.66mg·kg^(-1)。施肥区土壤有效磷含量处于较高水平,均值为69.87 mg·kg^(-1),但仍有20.00%的土壤有效磷含量处于中等及以下水平。研究表明,苏北设施葡萄园应注重土壤酸碱度的调节及磷肥的适量补充,控制钾、钙、镁肥的投入,合理增施有机肥。
