Abstract Greenhouse experiments were conducted to evaluate the utilization of compost derived from grape fruit waste (GFW) as an ingredient in nursery substrates for germination and development of cucumber. A randomized complete block design was used with thirteen treatments (S1-S13) encompassing 100% composted GFW, 60% GFW + 40% poultry manure including hardwood sawdust, 80% GFW + 20% broad bean straw, 80% GFW + 20% poultry manure including wheat straw, 50% coco peat + 50% vermiculite (as a control) and different combination of GFW-based composts with either coco peat or vermiculite. The resulted illustrated that GFW mixed with broad bean straw and poultry manure regardless of its source improved the chemical properties of composted GFW. Composts of GFW were even richer in nutrients, i.e., N, P, K, organic matter, soluble cations and anions and C/N ratio than control (50% coco peat + 50% vermiculite) except pH and electrical conductivity (EC), which was lower. Concentration of Cu, Fe, Cd and Pb were significantly lower in GFW composts than control substrate; while total phenolic content was significantly the highest in single compost of GFW. Mixing GFW composts with either vermiculite or coco peat (at 1:1 ratio by volume) was optimal for seed germination and seedling growth parameters; those combined substrates showed the highest FGP, CGRI, survival rate, and growth parameters in most cases. The negative effects of singly GFW compost can be removed or improved by mixing it with coco peat or vermiculite, so seed germination, seedling growth and survival rate significantly enhanced with mixing GFW-compost with coco peat or vermiculite substrates at ratio of 1:1. These recycled wastes are low cost products that can be usefully used in horticultural nurseries on a commercial scale. Highlights Grape fruit waste compost had similar chemical properties to coco peat and vermiculite mixture Grape fruit waste compost had the highest total phenolic content Replacing coco peat or vermiculite by GFW compost enhanced seed germination of cucumber Mixing GFW compost with either coco peat or vermiculite improved seedling development of cucumber Replacing coco peat or vermiculite by GFW compost reduced the cost by 50%

葡萄果废料堆肥作为优质黄瓜 (Cucumis sativus L.) 幼苗生产的苗圃基质成分

摘要 进行温室试验以评估来自葡萄果实废弃物 (GFW) 的堆肥作为黄瓜发芽和发育苗圃基质成分的利用。使用随机完整区组设计和 13 个处理 (S1-S13)，包括 100% GFW 堆肥、60% GFW + 40% 家禽粪便（包括硬木锯末）、80% GFW + 20% 蚕豆秸秆、80% GFW + 20% 家禽粪便包括麦秆、50% 椰子泥炭 + 50% 蛭石（作为对照）以及基于 GFW 的堆肥与椰子泥炭或蛭石的不同组合。结果表明，无论来源如何，GFW 与蚕豆秸秆和家禽粪便混合都可以改善堆肥 GFW 的化学性质。GFW 的堆肥甚至含有更丰富的营养物质，即 N、P、K、有机质、除了 pH 值和电导率 (EC) 较低外，可溶性阳离子和阴离子以及 C/N 比都比对照（50% 椰子泥炭 + 50% 蛭石）高。GFW 堆肥中 Cu、Fe、Cd 和 Pb 的浓度显着低于对照基质；而GFW单一堆肥的总酚含量显着最高。将 GFW 堆肥与蛭石或椰子泥炭混合（体积比为 1:1）对于种子发芽和幼苗生长参数是最佳的；在大多数情况下，这些组合底物显示出最高的 FGP、CGRI、存活率和生长参数。单独使用 GFW 堆肥的负面影响可以通过将其与可可泥炭或蛭石混合来消除或改善，因此种子发芽，将 GFW-堆肥与椰子泥炭或蛭石基质以 1:1 的比例混合后，幼苗的生长和成活率显着提高。这些回收废物是低成本产品，可用于商业规模的园艺苗圃。亮点 葡萄果渣堆肥与椰子泥炭和蛭石混合物具有相似的化学特性 葡萄果渣堆肥具有最高的总酚含量 用 GFW 堆肥替代椰子泥炭或蛭石促进黄瓜种子发芽 将 GFW 堆肥与椰子泥炭或蛭石混合可改善幼苗发育用 GFW 堆肥代替椰子泥炭或蛭石使成本降低 50%
