不同食用菌菌渣基质配比对莲藕叶片生长特性及莲藕产量的影响
Effects of Differential Spent Mushroom Substrate Formulation Ratios on Foliar Growth Dynamics and Rhizome Yield in Lotus Root
摘要
Abstract
To investigate the optimal substrate-soil mixing ratio for the growth and development of lotus root,this study used"E-Lian No.6"as the experimental material.Four treatments were established by mixing soil with spent mushroom substrate at different ratios(A:25%;B:50%;C:75%;D:0%,CK)to analyze their effects on leaf morphological traits,chlorophyll content,and yield-related characteristics of lotus root during the growth period.The results showed that Treatment A increased the chlorophyll content in lotus leaves,significantly promoted leaf growth,and enhanced the accumulation of soluble sugars,proteins,and other substances.Across the four growth stages of lotus root(sprouting,stem and leaf growth,tuber expansion,and harvesting),the soluble sugar content in leaves from Treatment A was 33.33%,8.33%,6.67%,and 37.5%higher than that in Treatment D(control),respectively.Additionally,the total lotus root weight in Treatment A was 37.50%higher than in Treatment D.In contrast,Treatment C exhibited lower levels of soluble sugars,proteins,and total lotus root weight compared to the control.In conclusion,the substrate-soil ratio in Treatment A was more suitable for the growth and development of"E-Lian No.6"lotus root.It indi-cates that an appropriate amount of spent mushroom substrate added to soil can promote healthy growth and quality formation in lotus roots.The results of this study provide a theoretical basis for soilless substrate cultivation of lotus roots.关键词
