| 摘 要： | 采用常规施肥、减20%施肥和不施肥3种施肥水平,研究两种耕作方式(半旱式、平作)对水稻产量、品质、稻田土壤和水体中氮、磷质量分数的影响.结果表明:①半旱式耕作方式在3种施肥水平下水稻产量均比平作同等施肥水平高,半旱式耕作有利于水稻增产.②半旱式常规减20%施肥水平下,土壤中氮、磷质量分数明显升高,水体中氮、磷呈现降低的趋势,有效地降低了氮、磷流失的风险;半旱式耕作对减少氮、磷流失的效果较平作方式好.

| Abstract: | In a field experiment,conventional fertilization,reduced-rate fertilization(reducing fertilizer rate by 20%) and no fertilizer were combined with two tillage methods(ridging cropping and flat cropping) to form 6 treatments and the influences of fertilization on rice yield and quality and on the content of nitrogen and phosphorus in the paddy field were studied.Ridging cropping of paddy rice was shown to be conducive to rice production,giving higher yield than flatting cropping under all the three fertilizer... |
