| 摘 要： | 以热带地区典型酸性水稻土为载体,通过设置不施肥处理（CK）、常规化肥（T）、有机无机复混肥（OF）、有机无机复混肥减施10%（10%OF）和有机无机复混肥减施20%（20%OF）等不同试验处理,研究化肥、有机无机复混肥和减量施用对海南省双季稻的产量、养分积累和肥料利用率的影响,评估有机无机复混肥及其减量施用对热带地区土壤化学性质的影响。研究结果表明,各施肥处理较CK均能显著提高水稻籽粒产量,OF处理较常规化肥能显著增加晚稻有效穗数,涨幅为29.79%。同时OF处理较常规化肥处理能显著提高早稻氮、磷累积量,增加幅度分别为19.31%和27.94%,20%OF处理能显著提高早稻氮、磷、钾肥农学效率;不同有机无机复混肥处理较常规化肥处理对土壤养分影响无显著性差异。

| Abstract: | In this paper, the typical acidic paddy soil in the tropics was used as the carrier to study the effects of chemical fertilizer, organic-inorganic compound fertilizer and reduced application on the yield, nutrient accumulation, fertilizer utilization rate of double-season rice and soil chemical properties in Hainan Province of the tropical regions through the application of no fertilization treatment (CK), conventional fertilizer (T), organic-inorganic compound fertilizer (OF), organic-inorganic compound fertilizer reduction 10% (10%OF) and organic-inorganic compound fertilizer reduction of 20% (20%OF). All fertilization treatment could significantly increase rice grain yield compared to CK. OF treatment could significantly increase the effective panicle number of late rice compared with conventional chemical fertilizer, with an increase of 29.79%. At the same time, OF treatment could significantly increase the accumulation of nitrogen and phosphorus in early rice compared with conventional chemical fertilizer treatment, with an increase of 19.31% and 27.94%, respectively. 20%OF treatment can significantly improve the agronomic efficiency of nitrogen, phosphorus and potassium fertilizers in early rice; Organic-inorganic compound fertilizer treatment had no significant difference in soil nutrients compared to conventional chemical fertilizers. |
