Abstract
为筛选出适合立体水培生产的可降解环保型种植载体,本研究对不同种植载体的原料特性、机械特性及栽培效果进行了分析.结果表明,与花泥型、淀粉型种植载体相比,生物质炭型种植载体的机械性能较好,其中生物质炭1的跌落损失率＜3.5%、粘附性＜0.2 N·mm、回弹率＞75%、内聚性＞0.5 N·mm、硬度＞80 N.其水培特性符合种植标准,pH值为6.68,吸水率为330.52%,保水率为93.64%,经过6周降解后的降解率为9.23%.其在育苗过程中的发芽率为66.67%;植株的壮苗指数最高,为3.91,种植后的EC值为667.33 ppm.通过主成分分析可知,竹炭+竹纤维为原料的生物质炭型载体的综合性能最好,为环境友好型种植载体的研究和应用提供了科学依据和技术支持,具有重要的理论和实践价值.
In order to screen out biodegradable and environmentally friendly planting vectors suitable for three-dimensional hydroponic production,the different planting substrates were analyzed from the raw material characteristics,mechanical properties,and hydroponic cultivation.The results showed that compared with peat and starch-based planting substrates,the biomass charcoal-based planting substrate had better mechanical properties.Among them,the biomass charcoal 1 had a drop loss rate of less than 3.5%,adhesion of less than 0.2 N·mm,rebound rate greater than 75%,cohesion greater than 0.5 N·mm,and hardness greater than 80 N.Its hydroponic characteristics met planting standards,with a pH of 6.68,water absorption rate of 330.52%,water retention rate of 93.64%,and degradation rate of 9.23%after six weeks.During the seedling stage,the germination rate of the biomass charcoal 1 planting substrate was 66.67%,and the strong seedling index of the plants was the highest at 3.91.The EC value after planting was 667.33 ppm.Comprehensive analysis showed that the biomass charcoal substrate made from bamboo charcoal and bamboo fiber had the best comprehensive performance.This provides scientific evidence and technical support for the research and application of environmentally friendly planting substrates and has important theoretical and practical value.
