摘　　要：[目的]为了提高单位面积的综合收益以实现农业的高效生产。[方法]2006年以玉米间作绞股蓝套作平菇的净收益为研究对象,开展玉米密度（30000～90000株/hm^2）、绞股蓝密度（15000～75000株/hm^2）以及玉米施肥量（纯N 75～255 kg/hm^2）对净收益影响的试验研究。[结果]在这种种植模式中,玉米的种植密度对净收益有极显著的影响,绞股蓝密度有显著影响,而玉米纯N施肥量无显著影响。在玉米密度为75000株/hm^2、绞股蓝种植密度为45000株/hm^2、玉米纯N施肥量为210 kg/hm^2时,净收益最高,达到33285元/hm^2。[结论]玉米种植密度是影响净收益的主要因素,其次为绞股蓝种植密度,玉米施肥量则无显著影响。　[Objective] The aim of the study was to increase comprehensive income per unit area and realize high-efficiency production of agriculture.[Method] With the net income of intercropping Gynostemma and interplanting mushroom in maize field in 2006 as study object,the experimental study on the effects of maize density（30 000～90 000 plants/hm^2）,Gynostemma density（15 000～75 000 plants/hm^2） and fertilization dosage for maize（75～255 kg/hm^2 based on pure N） on net income was conducted.[Result] In this planting model,maize density had extremely significant influence,Gynostemma density had significant influence and fertilization dosage of pure N for maize had no significant influence on net income.When maize was planted at 75 000 plants/hm^2,Gynostemma was planted at 45 000 plants/hm^2,fertilization of pure N for maize was at 210 kg/hm^2,the net income was highest,being 33 285 yuan/hm^2.[Conclusion] Maize density was main factor that influenced net income,the next was Gynostemma density and fertilization dosage for maize had no significant influence.
