玉米·平菇及绞股蓝高效间套复种技术研究

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/hm2)、绞股蓝密度(15000~75000株/hm2)以及玉米施肥量(纯N 75~255 kg/hm2)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/hm2、绞股蓝种植密度为45000株/hm2、玉米纯N施肥量为210 kg/hm2时,净收益最高,达到33285元/hm2。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。

Study on the High-efficiency and Comprehensive Cultivation Technology of Intercropping Gynostemma and Interplanting Mushroom in Maize Field

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/hm2),Gynostemma density(15 000～75 000 plants/hm2) and fertilization dosage for maize(75～255 kg/hm2 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/hm2,Gynostemma was planted at 45 000 plants/hm2,fertilization of pure N for maize was at 210 kg/hm2,the net income was highest,being 33 285 yuan/hm2.Conclusion] Maize density was main factor that influenced net income,the next was Gynostemma density and fertilization dosage for maize had no significant influence.
