As the scale of cultivation expands, challenges such as substrate shortages and rising production costs in mushroom cultivation have become increasingly prominent. Fruit tree pruning residue has the potential to serve as an alternative substrate, offering a sustainable solution. This study evaluates the feasibility of incorporating various types of fruit tree pruning residues into cultivation.
Different ratios of sawdust (QS), pruning (MPP), pruning (VVP), pruning (ADP), pruning (ZJP), and pruning (MAP) were tested as substrates. The effects on yield, amino acid profiles, and protein content of fruiting bodies were analyzed. The control substrate comprised 80% QS, and the experimental groups incorporated varying ratios of fruit tree residues.
Compared with the control, yields increased by 14.86% (QS-MPP), 8.1% (QS-VVP), 18.92% (QS-ZJP), and 22.97% (QS-MAP). The MAP group had 21.21% higher ash content, while the QS-MAP group exhibited the highest crude protein content (10.84% increase). The QS-MPP group showed the highest crude fiber content (1.72 g/100 g). Crude polysaccharide and fat contents in the ZJP group increased by 110.77% and 10.15%, respectively. Mineral content varied, with QS-MPP showing the highest calcium, potassium, manganese, and magnesium levels, and VVP exhibiting the highest iron and copper levels. Amino acid analysis revealed QS-MPP had the highest levels of threonine, valine, isoleucine, serine, cysteine, glycine, and histidine, while QS-VVP had the highest leucine, aspartate, glutamate, and arginine levels. The best formulation was determined as 40% QS, 40% MPP, 17% bran, 1% sucrose, 1% CaCO, and 1% gypsum.
These results highlight the potential of fruit tree pruning residues as a sustainable substrate for cultivation, ensuring high yields and enhanced nutritional quality. This approach can contribute to cost-effective and environmentally friendly mushroomproduction.
随着栽培规模的扩大，蘑菇栽培中诸如基质短缺和生产成本上升等挑战日益突出。果树修剪残枝有潜力作为替代基质，提供可持续的解决方案。本研究评估了将各种类型的果树修剪残枝纳入栽培的可行性。
测试了不同比例的锯末（QS）、[此处MPP、VVP、ADP、ZJP、MAP未明确具体果树种类，暂保留英文]修剪残枝作为基质。分析了对子实体产量、氨基酸谱和蛋白质含量的影响。对照基质由80%的QS组成，实验组加入了不同比例的果树残枝。
与对照相比，产量分别提高了14.86%（QS-MPP）、8.1%（QS-VVP）、18.92%（QS-ZJP）和22.97%（QS-MAP）。MAP组的灰分含量高21.21%，而QS-MAP组的粗蛋白含量最高（增加了10.84%）。QS-MPP组的粗纤维含量最高（1.72克/100克）。ZJP组的粗多糖和脂肪含量分别增加了110.77%和10.15%。矿物质含量各不相同，QS-MPP的钙、钾、锰和镁含量最高，VVP的铁和铜含量最高。氨基酸分析显示，QS-MPP的苏氨酸、缬氨酸、异亮氨酸、丝氨酸、半胱氨酸、甘氨酸和组氨酸含量最高，而QS-VVP的亮氨酸、天冬氨酸、谷氨酸和精氨酸含量最高。最佳配方确定为40%QS、40%MPP、17%麸皮、1%蔗糖、1%碳酸钙和1%石膏。
这些结果突出了果树修剪残枝作为蘑菇栽培可持续基质的潜力，可确保高产并提高营养品质。这种方法有助于实现经济高效且环境友好的蘑菇生产。
