ABSTRACT Greenhouse trials were conducted to evaluate the effect of several locally available carbon (C) sources on weed suppression using anaerobic soil disinfestation (ASD). Carbon sources included rice bran, sorghum-sudangrass, cowpea, buckwheat, paper mulch, brewer`s spent grain, waste coffee grounds, and peanut shells applied at 4 mg of C/g of soil. All trials were conducted in containers of 0.2-m height and 0.15-m diameter. The germination of common chickweed, redroot pigweed, white clover, and yellow nutsedge was reduced similarly with all C sources used for ASD. The addition of distiller’s yeast at 10 kg/ha to C sources at 4 mg of C/g of soil provided similar or better weed control than ASD treatments with C sources alone. ASD treatments in all trials reduced weed viability from 50% to 100% compared to the non-treated control. Redox potential in all ASD treatments during the 3-week treatment was lower (more anaerobic) than the non-treated control.

用于厌氧土壤消毒的各种碳源的杂草控制评估

摘要 进行温室试验以评估几种当地可用碳 (C) 源对使用厌氧土壤消毒 (ASD) 抑制杂草的影响。碳源包括米糠、高粱-苏丹草、豇豆、荞麦、纸覆盖物、啤酒糟、废咖啡渣和花生壳，每克土壤施用 4 毫克碳。所有试验均在 0.2 米高和 0.15 米直径的容器中进行。普通繁缕、红根杂草、白三叶草和黄坚果的萌发率与用于 ASD 的所有 C 源相似。将 10 kg/ha 的蒸馏酵母添加到 4 mg C/g 土壤的 C 源中，提供了与单独使用 C 源的 ASD 处理相似或更好的杂草控制。与未处理的对照相比，所有试验中的 ASD 处理都将杂草活力从 50% 降低到 100%。
