NUS科学家创造了可生物降解的微针片,将生物肥料直接送入植物,促进生长,将化肥使用量削减15%或以上。 NUS scientists created biodegradable microneedle patches that deliver biofertilizer directly into plants, boosting growth and cutting fertilizer use by 15% or more.

NUS科学家开发了可生物降解的微针片,将生物肥料直接输送到植物组织中,促进Choy Sum和Kale等蔬菜的生长,同时将肥料的使用减少15%以上。 NUS scientists have developed biodegradable microneedle patches that deliver biofertiliser directly into plant tissues, enhancing growth in vegetables like Choy Sum and Kale while reducing fertilizer use by over 15%. 这些用聚乙烯醇制成的补丁,在接触后一分钟内溶解,将有益的微生物直接释放到叶或茎中。 The patches, made from polyvinyl alcohol, dissolve within a minute upon contact, releasing beneficial microbes directly into leaves or stems. 这种方法改善了微生物向根部的传播,绕过了竞争和pH值转移等土壤挑战。 This method improves microbial delivery to roots, bypassing soil challenges like competition and pH shifts. 温室测试表明,与基于土壤的应用相比,生物量、叶叶面积和高度都有所增加。 Greenhouse tests showed increased biomass, leaf area, and height compared to soil-based application. 该系统使用3D打印的应用程序进行均衡分配,使精确剂量和潜在的自动化成为可能。 The system uses a 3D-printed applicator for even distribution, enabling precise dosing and potential automation. 该技术为可持续城市和纵向耕作提供了很有希望的解决办法,减少了对环境的影响。 The technology offers a promising solution for sustainable urban and vertical farming with reduced environmental impact.
