摘要: 本试验研究两种调理剂配合施用对设施土壤氮素转化与作物氮素吸收的影响,以腐植酸和生物炭作为供试材料,共设六个处理。结果表明,腐植酸和生物炭以不同配比配合施用的各处理中对甜高粱对于氮素吸收效果较好的是1/2腐植酸 + 生物炭处理,对于土壤氮素转化效果较好的是腐植酸 + 生物炭处理,这些处理对降低土壤氮素积累、促进土壤氮素转化有积极作用。
Abstract: This study investigated the effects of combined application of two conditioning agents on soil ni-trogen transformation and nitrogen uptake in crops. The test used humic acid and biochar as test materials, and a total of six treatments were set up. The results showed that the 1/2 humic acid + biochar treatment had better nitrogen absorption effect on sweet sorghum than on sweet sorghum with different ratios of humic acid and biochar in various treatments, and the humic acid + biochar treatment had better nitrogen conversion effect on soil, which had a positive effect on reducing the accumulation of soil nitrogen and promoting the conversion of soil nitrogen.
