为了研究菊芋发酵秸秆作为栽培基质对韭菜生长和品质的影响，使用“雪晶特号”韭菜为试材，以基质土、蛭石、珍珠岩作为基础基质，复配0%、10%、20%、30%菊芋发酵秸秆，形成四种栽培基质处理(T1、T2、T3、T4),通过测定复配基质在0 d和100 d的理化性质以及韭菜100 d时的生长及品质指标的相关性分析，探究复配基质的不同配比对韭菜生长的影响。结果表明：菊芋秸秆的复配基质相比于常规复配基质可以提高韭菜的长势、品质及产量，其中，20%秸秆添加量处理pH在100 d时呈微酸性(6.76),且容重较大，持水孔隙和通气孔隙比值较优，叶身宽和假茎粗较大，维生素C含量显著大于其它处理，相关性分析结果表明产量与纤维素含量、维生素C含量、容重和孔隙度呈正相关，与pH、EC、气水比、可溶性蛋白和干物质含量呈负相关。综上，添加菊芋秸秆量为20%时，韭菜的品质较好且产量最高。
Abstract：This study investigated the effects of incorporating fermented Jerusalem artichoke straw as a cultivation substrate on the growth and quality of chives, specifically using the “Xuejing Tehao” variety. Four substrate treatments(T1, T2, T3, T4) were formulated by combining base substrates of soil, vermiculite, and perlite with 0%, 10%, 20%, and 30% fermented Jerusalem artichoke straw, respectively. The physicochemical properties of the substrates were evaluated at both the initial stage and after 100 days, alongside the growth and quality parameters of chives measured at the 100-day mark, to comprehensively assess the impact of varying substrate compositions on chive development.The results indicated that composite substrates containing Jerusalem artichoke straw significantly outperformed conventional substrates in promoting chive growth, quality, and yield. The treatment with 20% straw addition achieved the best results, featuring a slightly acidic pH(6.76) at 100 days, higher bulk density, an optimal balance of water-holding and aeration pores, broader leaves, thicker pseudostems, and significantly higher vitamin C content compared to other treatments. Correlation analysis revealed that yield was positively associated with cellulose content, vitamin C content, bulk density, and porosity, while negatively correlated with pH, EC, gas-to-water ratio, soluble protein, and dry matter content.In conclusion, incorporating 20% fermented Jerusalem artichoke straw into the substrate optimized chive growth conditions, enhanced quality, and achieved the highest yield, demonstrating its potential for practical agricultural applications.
