营养液浓度对复配锯末栽培青甘韭生长及品质的影响
Effects of Nutrient Solution Concentration on Growth and Quality of Allium Przewalskianum Cultivated in Mixed Sawdust Substrate
为明确以锯末为主料配方基质栽培青甘韭时的营养液浓度,以市售AB肥为营养液原料,设6个浓度处理,采用青甘韭种子直播方式开展苗期栽培试验,结果表明:与对照相比,营养液栽培优于传统栽培模式。5/3标准浓度处理的叶长指标最佳,分蘖数显著提高,2倍标准浓度处理对叶长、部分茎粗和部分品质指标表现出抑制趋势。
To clarify the optimal nutrient solution concentration for sawdust-based substrate cultivation of Alliumprzewalskianum 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.
