摘　　要：增施有机肥是提高土壤质量、保障水稻稳产增产的重要手段之一。本研究于2021年在沿江平原水稻田进行大田试验,明确不同用量(3 000~6 000 kg/hm^(2))炭基有机肥或生物有机肥对土壤养分及水稻产量的影响。结果表明:与常规施肥相比,生物有机肥处理土壤有效磷含量显著提高13.1%~24.4%;高用量生物有机肥处理碱解氮含量显著提高19.9%;中、高用量炭基有机肥处理土壤有效磷含量分别提高13.1%和18.6%;高用量炭基有机肥处理土壤速效钾含量提高12.5%。生物有机肥对水稻产量的提升效应优于炭基有机肥,与常规施肥相比,中、高用量生物有机肥处理分别使水稻产量显著增加16.1%和22.1%,高用量炭基有机肥处理水稻增产15.9%。Increasing the application of organic fertilizer is one of the important means to improve soil quality and ensure the stable yield and increase yield of rice. In 2021, a field experiment was conducted in the paddy field of the plain along the Yangtze River to determine the effects of different amounts of carbon based organic fertilizer or biological organic fertilizer(3 000-6 000 kg/hm^(2)) on soil nutrients and rice yield. The results showed that, compared with the conventional fertilization, the available phosphorus content in soil in biological organic fertilizer treatment significantly increased by 13.1%-24.4%, and the alkali hydrolyzable nitrogen content in high amount of biological organic fertilizer treatment significantly increased by 19.9%. The available phosphorus content in soil increased by 13.1% and 18.6%,respectively in the treatments of medium and high amount of carbon based organic fertilizer. The available potassium content of soil increased by 12.5% in the treatment of high amount of carbon based organic fertilizer. The effect of biological organic fertilizer on rice yield was better than that of carbon based organic fertilizer. Compared with the conventional fertilization, the rice yield significantly increased by 16.1% and 22.1% in the treatments of medium and high amount of biological organic fertilizer, and increased by 15.9% in the treatment of high amount of carbon based organic fertilizer.
