猪粪炭基肥替代化肥对土壤肥力与水稻产量的影响

Effect of Pig Manure Biochar-Based Fertilizer Replacing Chemical Fertilizer on Soil Fertility and Rice Yield

畜禽废弃物可以制成生物炭来改良土壤,提高土壤肥力。本文通过开展田间试验,研究猪粪炭基肥部分替代化肥对土壤肥力和水稻产量的影响。试验结果表明,施用猪粪炭基肥部分替代化肥,可以有效增加土壤肥力,提高水稻产量。不同处理的效果存在差异,其中炭基肥80%替代化肥的处理效果最显著,相较于CK处理增产10.42%,全氮、速效磷、速效钾、有机质分别增长5.80%、15.45%、13.47%和5.78%。

Animal waste can be made into biochar to improve soil and enhance soil fertility.Through field experiments,this study investigates the effects of partially replacing chemical fertilizer with pig manure biochar-based fertilizer on soil fertility and rice yield.The experimental results indicate that using pig manure biochar-based fertilizer as a partial substitute for chemical fertilizer can effectively increase soil fertility and increase rice yield.There are differences in the effects of different treatments,among which the treatment of 80%biochar-based fertilizer replacing chemical fertilizer has the most significant effect,increasing yield by 10.42%compared to CK treatment,and increasing total nitrogen,available phosphorus,available potassium,and organic matter by 5.80%,15.45%,13.47%,and 5.78%,respectively.
