摘要: 为促进富磷型生物炭肥在西南紫色土区的合理利用,采用盆栽试验研究了不同配比富磷型猪粪基生物炭肥对紫色土理化性质以及樱桃萝卜产量和品质的影响。结果表明,添加富磷型猪粪基生物炭肥后土壤pH值以及有机质、全氮和全钾含量均显著提高,樱桃萝卜莲座期和肉质根膨大期速效磷含量分别提高21.72%~43.47%和0.22%~28.42%。富磷型猪粪基生物炭肥处理樱桃萝卜地上部和根部生物量分别增加17.20%~44.17%和20.63%~83.31%,樱桃萝卜的磷、总糖和维生素C含量均显著提高,且樱桃萝卜磷含量与土壤速效磷含量呈极显著相关;樱桃萝卜Pb和Cd含量分别降低6.12%~44.49%和4.19%~13.31%。施用富磷型猪粪基生物炭肥能够显著改善紫色土理化性质并提升樱桃萝卜产量和品质。

Abstract: In order to promote the rational application of phosphorus(P)-enriched biochar fertilizer in purple soil of southwest China, pot experiments were conducted to investigate the effects of P-enriched biochar fertilizer prepared from pig manure on the physicochemical properties of purple soil, as well as its influence on the yield and quality of cherry radish. The results show that after adding P-enriched biochar fertilizer prepared from pig manure, the soil pH value and organic matter, total N and total K contents in soil were significantly increased. The opplication of P-enriched biochar fertilizer also increased the contents of available P by 21.72%-43.47% and 0.22%-28.42% during the rosette stage and fleshy root swelling stage of cherry radish, respectively. The above-ground and root biomass of cherry radish treated with this P-enriched biochar fertilizer were lifted by 17.20%-44.17% and 20.63%-83.31%, respectively. The contents of P, total sugar and vitamin C in cherry radish were significantly increased, and the content of P in cherry radish had a significant correlation with the content of available P in soil (P<0.01), while the Pb and Cd contents of cherry radish decreased respectively by 6.12%-44.49% and 4.19%-13.31%. In conclusion, application of P-enriched biochar fertilizer prepared from pig manure can significantly improve the physicochemical properties of purple soil, and increase the yield and quality of cherry radish.
