摘　　要：采用土柱载培试验方法研究了有机无机肥料配合施用对冬小麦根系和旗叶衰老的影响，结果表明，有机无机肥料配合施用，有效地降低了根系和旗叶的膜脂过氧化作用，提高了活性氧清除系统的超氧物歧化酶的活性；增强了根系活力，提高根系干重特别是40—100cm土层的根系干重；降低了旗叶光合速率的衰减率，延缓了根系和旗叶的衰老，提高了粒重、生物产量和经济系数，增加了籽粒产量。The effects of combined application of organic manure and fertilizers on senescences of root and flag leaf in winter wheat (Triticum aestivum L.) were studied through experiment with soil column culture. The results showed that the combined application of organic manure and fertilizers resulted in a decrease of lipid peroxidation and an increase of superoxide dismutase (SOD) activity in root and flag leaf after anthesis, increased the root vigour and dry root weight especially in 40-100cm soil layer, reduced the decline fate of photosynthetic rate of flag leaf, delayed the senescences of root and flag leaf, increased the grain weight biomass, economic index and grain yield.
