| 摘 要： | 为了研究在不同间套作模式下增施有机肥对中低产土壤肥力的影响,特进行了不同绿肥间套作方式对地力培肥的影响试验,结果表明,改良培肥区有机肥和无机肥施用比例为1∶1左右,玉米产量比常规施肥平均增产102.5kg/667m2,平均增产率为23.05%,其中马铃薯/绿肥/玉米分带种植模式增产幅度较小(51.2～66kg/667m2),而油菜/绿肥/玉米和小麦/绿肥/玉米种植,增产幅度在100kg/667m2以上.改良培肥区与常规施肥相比,有机质、全氮、碱解氮、速效磷、速效钾平均分别提高0.23%、0.033%、23.23mg/kg、1.5mg/kg和17.75mg/kg,土壤肥力指标都有所提高,同时玉米生长健壮,植株高大、粗壮,穗大、粒多,粒重,秃尖率低,产量高. |

| Abstract: | The results from the effects of different intercropping and interplant patterns of green manure on soil fertility showed that the maize yield in improved soil fertility areas under 1:1 application ratio between organic and inorganic fertilizer averagely increased by 23.05%(102.5 kg/667m2) compared with the conventional application pattern,The yields of the potato/green manure/maize pattern,rape/green manure/maize pattern and wheat/green manure/maize pattern increased by 51.2 to 66 kg/667m2,146.1 kg/667m2 an... |
