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
In order to clarify the application effect of biogas slurry and the capacity of safe digestion, the effects of different irrigation volumes of biogas slurry on the growth, yield, quality and soil fertility were studied in the field. The results showed that the yield of biogas slurry was increased from 26.45% to 33.70% and 8.72% to 14.95%, respectively, compared with blank control and total chemical fertilizer treatment with the application rate of 420-1 260 t · hm -2. The amount of biogas slurry used for conventional nitrogen application was 3 times
