摘要： 大田定位试验结果表明，有机无机肥配施可提高水稻根系活力，减缓旗叶叶绿素和蛋白质的降解，延缓水稻旗叶衰老，提高水稻分蘖成穗率、结实率、千粒重和水稻产量。此外，有机无机肥配施还可提高红壤性水稻土的土壤肥力，改善土壤物理性状，是红壤性水稻土培肥和增产的有效措施。

Abstract: Results of field experiment showed that combined application of organic manure and fertilizers increased root vigor，reduced the decline of chlorophyll and protein content and the senescence of flag leaf，increased ear/tillering ratio, percentage of full grains，weight of thousand grains and rice grain yield. In addition, combined application of organic manure and fertilizers had positive effects on improving soil fertility and physical characteristics. In a word，combined application of organic manure and fertilizers is a effective measure of improving soil fertility and rice grain yield.
