【目的】为探明不同稻草还田方式与稻田养鸭耦合对水稻生物量、产量及土壤养分的影响。【方法】设置5种处理方式:“稻草炭化还田+养鸭”(CD),“稻草直接还田+养鸭”(ZD),“稻草粉碎还田+养鸭”(FD),“稻草不还田+养鸭”(BD)和“稻草不还田不养鸭”(BR)。通过测定水稻生物量、产量,土壤全氮、全磷、全钾、有机质、碱解氮含量及土壤pH值,研究稻草还田+稻田养鸭对土壤养分及水稻生物量和产量的影响。【结果】稻草炭化还田+稻田养鸭(CD)能显著降低水稻株高、提高水稻生物量,稻草还田+稻田养鸭主要通过增加水稻有效穗来提高水稻产量,短期内(1年)能使水稻增产10 %以上。稻草还田+稻田养鸭能显著增加土...

【Objective】The study aimed to find out the effects of different straw returning methods and rice-ducking on rice biomass,yield and soil nutrient.【Method】five kinds of treatment methods were set up: ‘straw charcoal returning to field+ raising duck’(CD),‘straw directly returning to field+ raising duck ’(ZD),‘straw smashing back to the field+ raising ducks’(FD),‘straw grass is not returned to the field+ raising ducks’(BD) and‘straw grass is not returning to the field without raising ducks’(BR). The effects of rice straw returning and...
