【摘要】 以茭白"浙茭3号"为试材,采用单因素试验的方法,设置8个施肥处理,研究了每667 m~2追施不同用量沼液对茭白生物学性状、经济性状、物候期和产量的影响,以期为茭白高效消纳沼液提供参考依据。结果表明:不同用量沼液处理间的生物学性状、产量、病害发生均无显著差异,沼液作为追肥量每667 m~2不宜超过5 t,化肥可以减量施用50%,在浙江丽水大棚早春栽培中,以每667 m~2用沼液5 t+碳铵25 kg+过磷酸钙12.5 kg为宜。更多还原

【Abstract】 The effects of different fertilizing dosages of biogas slurry(eight treatments)on biological and economic traits,phenophase and yield of Zizania latifolia ‘Zhejiao No.3’(named commonly as water bamboo)were studied by single factor test,in order to provide theoretical basis for the efficient elimination of biogas slurry by Zizania latifolia.The results showed that there was no significant difference in biological characteristics,yield and disease occurrence among different dosages of biogas slurry treatments.As used to be topdressing,the application amount of biogas slurry should not exceed 5 tper 667 m~2,and chemical fertilizer could be reduced by 50%.When cultivated in greenhouse in early spring in Lishui,Zhejiang Province,Zizania latifolia is optimally fertilized with 5 tbiogas slurry,25 kg ammonium carbonate and 12.5 kg of superphosphate per 667 m~2.更多还原
