摘要:

为构建环境友好型育苗基质体系,基于混料试验设计法,以鹿茸菇渣(Lyophyllum decastes residue,LDR)替代草炭,系统评估其不同配比复配基质对加工辣椒幼苗的生长调控效应。通过解析基质理化性质、幼苗生长指标、生物量积累和根系形态特征,发现LDR在养分含量、孔隙结构方面显著优于传统草炭。当复配比例为草炭:LDR:珍珠岩=6:3:1时,幼苗叶面积、壮苗指数、根系活力较对照(草炭:珍珠岩=8:2)处理分别提高17.32%、13.11%、7.58%;幼苗地上部鲜重、干重分别增加26.44%、14.47%;总根长、总根表面积分别增加了10.05%、12.76%。30%LDR替代草炭不仅可降低育苗成本,还可通过根冠协同作用促进辣椒幼苗生长。

Abstract:

To establish an environmentally friendly seedling substrate system, this study employed a mixture experimental design to systematically evaluate the growth-regulating effects of Lyophyllum decastes residue (LDR)-based composite substrates with varying ratios on processing pepper seedlings. By analyzing changes in substrate physicochemical properties, seedling growth metrics, biomass accumulation, and root morphology, LDR exhibited significantly superior nutrient content and pore structure compared to traditional peat. At the optimal ratio of peat: LDR: perlite=6:3:1, seedling leaf area, strong seedling index, and root activity increased by 17.32%, 13.11%, and 7.58%, respectively, compared with the control CK (peat: perlite=8:2). Fresh and dry weights of aboveground biomass rose by 26.44% and 14.47%, while total root length and root surface area expanded by 10.05% and 12.76%. Substituting 30% peat with LDR reduces costs while enhancing pepper seedling growth through root-shoot synergy.
