营养液浓度对复配锯末栽培青甘韭生长及品质的影响OA

To clarify the optimal nutrient solution concentration for sawdust-based substrate cultivation of Allium przewalskianum using commercial AB fertilizer as the nutrient source,six concentration treatments were set up,and the seedling cultivation experiment was carried out using the direct seeding method.Results demonstrated that compared with traditional cultivation(control),nutrient solution cultivation showed superior performance.The 5/3-fold standard concentration treatment achieved optimal leaf length and significantly increased tiller numbers,and the 2-fold standard concentration treatment showed inhibitory trends in leaf length,some stem diameter,and some quality indicators.
