摘要: 为明确茭白种植季沼液施用效应及安全消解容量,在田间研究沼液不同灌溉量对茭白营养生长、产量、品质及土壤肥力质量的影响。结果表明,沼液施用量420~1 260 t·hm-2处理,产量比空白对照和全化肥处理分别提高2645%~3370%和872%~1495%。以茭白常规施氮量3倍的沼液用量630 kg N·hm-2是当季茭白消解沼液的安全容量。

Abstract: A field experiment was conducted to determine effects of different biogas slurry irrigation amounts on yield and quality of Zizania caduciflora and soil fertility as well as safety digestion capacity of biogas slurry. The results showed that application of 420-1 260 t · hm-2 biogas slurry increased Zizania caduciflora yields by 2645%-3370% and 872%-1495%, respectively, as compared to the treatments of no fertilizer (CK) and chemical fertilizers. Under the premise of ensuring Zizania caduciflora production, food security, and soil environment safety, a safe capacity of biogas slurry disposal in Zizania caduciflora field per season was about 630 kg N·hm-2.
