【目的】探讨不同有机肥部分替代基施化学氮肥对双季稻生长发育、氮素积累及产量的影响,为双季稻区选择适宜有机肥种类、提高水稻产量及土壤培肥提供理论依据与技术支撑。【方法】2016~2017年以早稻品种中早39和晚稻品种H优518为供试材料,在施氮(N)150 kg/ha、氮肥基肥∶蘖肥∶穗肥=5∶3∶2条件下,以100%化学氮肥处理为对照(CK),设4个有机肥+化学氮肥处理:T1,紫云英(早稻)/水稻秸秆(晚稻)+化肥;T2,生物炭+化肥;T3,厩肥+化肥; T4,菜籽饼肥+化肥。研究不同处理对双季稻生长发育、氮素积累及产量的影响。【结果】与CK相比,各有机肥处理早晚稻产量均有明显提高,T1~T4处理2016和2017年早稻产量分别较...

【Objective】The impacts of substitution of chemical nitrogen(N)fertilizer with different organic fertilizers on rice growth,N accumulation and yield of double cropping rice were studied to provide theoretical basis and technical support for improving soil fertility of double cropping rice fields.【Method】In 2016-2017,early rice variety Zhongzao 39 and late rice variety H You 518 were used as materials. Under the condition where nitrogen application rate was 150 kg/ha and the ratio of basic fertilizer∶tiller fertilizer∶granule fertilize was ...
