The co-application of biochar and wood vinegar has demonstrated the potential to enhance premium crop production. The present study reveals the effects of co-applying rice husk biochar and wood vinegar (both foliar and soil application) on soil properties and the growth of Chinese cabbage (Brassica chinensis L.) in a two-season pot experiment.
The soil pH, electrical conductivity and dissolved organic carbon contents in combination treatments of wood vinegar and biochar were increased more when wood vinegar was applied to soils rather than to leaves, and the parameters were observed to surpass those for chemical fertilizer treatments. The biomass of Chinese cabbage shoots was significantly increased by 60.8- and 27.3-fold in the combined treatments compared to the control when 1% wood vinegar was sprayed to the leaves (WF1) in 2022 and 2023, respectively. Higher contents of vitamin C, soluble protein and soluble sugar were also observed in the combined wood vinegar and biochar treatments compared to chemical fertilizer treatments and the control; for example, the vitamin C content of plant shoot in WF1 was 21.3 times that of the control. The yield and quality of plants were decreased across all treatments in 2023 compared to 2022 but the combination treatments still displayed superiority.
The co-application of wood vinegar and biochar enhances the growth and improve the quality of Chinese cabbage through improving the soil properties and plant photosynthesis. Moreover, the foliage application of wood vinegar is more preferable compared to soil application. © 2024 Society of Chemical Industry.
生物炭和木醋液的共同应用已被证明具有提高优质作物产量的潜力。本研究通过两季盆栽试验揭示了稻壳生物炭和木醋液（叶面和土壤施用）共同施用对土壤特性和白菜（Brassica chinensis L.）生长的影响。
与叶面施用相比，木醋液土壤施用时，土壤 pH 值、电导率和溶解有机碳含量的增加更为明显，且这些参数均超过化肥处理。与对照相比，2022 年和 2023 年分别叶面喷施 1%木醋液（WF1）时，白菜茎生物量分别增加了 60.8 倍和 27.3 倍。与化肥处理和对照相比，木醋液和生物炭共同处理的植株维生素 C、可溶性蛋白和可溶性糖含量也更高；例如，WF1 植株茎部的维生素 C 含量是对照的 21.3 倍。与 2022 年相比，2023 年所有处理的植物产量和品质均有所下降，但组合处理仍具有优势。
木醋液和生物炭的共同施用通过改善土壤特性和植物光合作用来促进白菜的生长和提高品质。此外，与土壤施用相比，木醋液叶面施用更为可取。 © 2024 化学工业协会。
