The effect of biomass ash and clay on tomato plants () in greenhouse conditions from germination to production was studied. Biomass ash is a waste obtained from thermal treatment of guishe (a by-product of natural fiber), and clay is collected from local soils. Several trials were performed to assess the influence of the addition of clay and guishe-ash on seeds germination, seedling growth, and production yield. The decrease in the values of these variables was considered an indicator of toxicity. The obtained results showed that based clay/ash materials positively affect germination (average ∼90% and six materials allow obtaining 90%) and seedlings growth (an increase of ∼20% in height and more than 50% in fresh air corpuscular weight). However, applying these materials on the production stage induces minor positive effects on fruit diameter, locule number, pericarp thickness, and the number of seeds per fruit. Also, adverse effects (first harvest yield, number of fruits, fresh mass of ripe fruits, lycopene content) were observed. To valorize biomass ash, its combination with other materials such as clay could be an alternative to improve tomato production.
研究了生物质灰和粘土对温室条件下从发芽到生产的番茄植株的影响。生物质灰是热解桂石（天然纤维的副产品）获得的废物，粘土则从当地土壤中收集。进行了多次试验来评估添加粘土和桂石灰对种子发芽、幼苗生长和产量的影响。这些变量值的降低被认为是毒性的指标。结果表明，基于粘土/灰分材料可显著促进种子发芽（平均约为 90%，有 6 种材料可达到 90%）和幼苗生长（高度增加约 20%，鲜重增加超过 50%）。然而，在生产阶段应用这些材料对果实直径、心室数、果皮厚度和每果种子数的影响较小。此外，还观察到了不良影响（首次收获产量、果实数量、成熟果实的鲜重、番茄红素含量）。为了提高生物质灰的价值，将其与粘土等其他材料结合使用可能是提高番茄产量的一种替代方法。
