RESULTS: Low-dose BAR (≤ 25 t ha-1 for cotton; ≤ 50 t ha-1 for sugar beet) effectively increased biomass, plant height, leaf area index (LAI), water and fertility (N, P and K) productivities, and yield. Biochar application increased the salt absorption and sugar content in sugar beet, with the most notable increases being 116.45% and 20.35%, respectively. Conversely, BAR had no significant effect on cotton fiber quality. The GRA method was the most appropriate for assessing crop growth and quality. The most indicative parameters for reflecting cotton and sugarbeet growth and quality status were biomass and LAI. The 10 t ha-1 BAR consistently produced the highest scores and was the most economically viable option, as evaluated by DTOPSIS-EW.
CONCLUSIONS: The optimal biochar application strategy for improving cotton and sugar beet cultivation in Xinjiang, China, is 10 t ha-1 biochar applied continuously. © 2024 Society of Chemical Industry.
结果:低剂量BAR(棉花≤25tha-1;甜菜≤50tha-1)有效增加了生物量,植物高度,叶面积指数(LAI),水和肥力(N,P和K)生产率,和产量。生物炭的施用增加了甜菜中的盐吸收和糖含量,最显著的增长是116.45%和20.35%,分别。相反,BAR对棉纤维品质没有显著影响。GRA方法最适合评估作物生长和质量。反映棉花和甜菜生长和品质状况的最具指示性参数是生物量和LAI。10tha-1BAR始终产生最高分,是最经济可行的选择,由DTOPSIS-EW评估。
结论:优化新疆棉花和甜菜种植的生物炭应用策略,中国,连续施用10tha-1生物炭。©2024化学工业学会。
