摘　　要：长期非粮化利用导致耕地土壤板结及土壤有机质含量下降、酸化、盐渍化、养分失衡和重金属污染等土壤质量退化,特别是苗木基地的耕作层剥离,引起耕作层变薄甚至消失,对土壤肥力的影响更甚。本试验通过不同生物质炭施用量及与商品有机肥配施,分析其对水稻产量和土壤肥力的影响,从而获得较佳的非粮化耕地的快速培肥技术模式。试验表明,相较于CK,各处理均提升了水稻土壤中的碱解氮、速效钾、有机质含量,且施用生物质炭同时添施12 t·hm^(-2)的商品有机肥对其改良作用更为显著。体现了生物质炭对稳定土壤pH值及养分固持上起一定作用,对水稻产量的提高具有积极作用。Long-term non-grain utilization leads to soil compaction,soil organic matter content reduction,acidification,salinization,nutrient imbalance and heavy metal pollution and other soil quality degradation,especially the soil layer stripping of seedling base,resulting in thinning or even disappearance of the soil layer,which has a greater impact on soil fertility.In this experiment,the effects of different biomass carbon application rates and combined with commercial organic fertilizer on rice yield and soil fertility were analyzed,so as to obtain a better rapid fertilizer technology model for non-grain cultivated land.The results showed that compared with CK,all treatments increased the contents of alkali-hydrolyzed nitrogen,available potassium and organic matter in rice soil,and the application of biochar combined with 12 t·hm^(-2) commercial organic fertilizer had a more significant effect on the improvement.It shows that biochar plays a certain role in stabilizing soil pH value and nutrient retention,and plays a positive role in improving rice yield.
