ABSTRACT A field experiment was conducted over two years to evaluate the effects of biochar (B) and poultry manure (PM) on soil properties, leaf nutrient concentrations and root yield of radish. The experiment consisted of 3 × 3 factorial combinations of B (0, 25 and 50 t ha−1) and PM (0, 2.5 and 5.0 t ha−1). Applications of B and PM on their own, and in combination, improved soil physical and chemical properties, leaf nutrient concentrations and yield components of radish. In the second year (2016), application of B on its own increased soil pH and concentrations of organic matter, N, P, K, Ca and Mg, as well as leaf nutrient concentrations and yield, but in the first year (2015) it only increased soil pH and organic matter. In both years, application of B influenced root length of the radish significantly. There was a significant interaction effect of biochar and poultry manure, which was attributed to the ability of the B to increase the efficiency of the utilization of the nutrients in the PM. The combination of 50 t ha−1 B and 5 t ha−1 PM resulted in the highest radish yield, with increases in root weight by 193%, 252% and 252% compared with B alone at 50 t ha−1, at 25 t ha−1 and no application of B or PM, respectively. Therefore, for a short season crop like radish the expected benefit of applying B on its own without PM may not be achieved within the first year.

生物炭和家禽粪便对土壤特性和萝卜 (Raphanus sativus L.) 产量的影响

摘要进行了两年多的田间试验,以评估生物炭 (B) 和家禽粪便 (PM) 对土壤特性、叶片养分浓度和萝卜根产量的影响。实验由 B(0、25 和 50 t ha-1)和 PM(0、2.5 和 5.0 t ha-1)的 3 × 3 因子组合组成。B 和 PM 的单独施用和组合施用改善了土壤理化性质、叶片养分浓度和萝卜的产量构成。在第二年(2016 年),单独施用 B 增加了土壤 pH 值和有机质、N、P、K、Ca 和 Mg 的浓度,以及叶片养分浓度和产量,但在第一年(2015 年)它只会增加土壤的 pH 值和有机质。在这两年中,B 的施用都显着影响了萝卜的根长。生物炭和家禽粪便之间存在显着的交互作用,这归因于 B 提高 PM 中养分利用效率的能力。50 t ha-1 B 和 5 t ha-1 PM 的组合导致萝卜产量最高,与单独 B 相比,在 50 t ha-1、25 时根重增加了 193%、252% 和 252% t ha−1 和不应用 B 或 PM,分别。因此,对于像萝卜这样的短季作物,在第一年内可能无法实现在没有 PM 的情况下单独施用 B 的预期收益。在 50 t ha-1、25 t ha-1 和不施用 B 或 PM 时,与单独使用 B 相比,分别为 252% 和 252%。因此,对于像萝卜这样的短季作物,在第一年内可能无法实现在没有 PM 的情况下单独施用 B 的预期收益。在 50 t ha-1、25 t ha-1 和不施用 B 或 PM 时,与单独使用 B 相比,分别为 252% 和 252%。因此,对于像萝卜这样的短季作物,在第一年内可能无法实现在没有 PM 的情况下单独施用 B 的预期收益。
