摘要
为探索适应种植业结构调整、提高花生种植效益的花生/玉米间作模式,开展以鲜食糯玉米2行间作不同垄数(1垄、2垄、3垄)花生的对比试验,分析不同间作模式对花生农艺性状、产量及经济效益的影响。结果表明:花生主茎高和第一对侧枝长随间作垄数的增加而降低,饱果数、单株果重、百果重、百仁重随花生间作垄数的增加而增加,2行玉米间作3垄(6行)花生产量与花生净作(对照)相当,显著高于间作1垄(2行)和2垄(4行)花生的处理。花生/玉米间作最适行比为2行玉米间作3垄(6行)花生,该模式可获得最大的经济产量。
In order to explore the peanut-maize intercropping mode to adapt to the planting structure adjustment and improve the benefit of peanut cultivation,a comparative experiment was conducted that two rows of fresh waxy corn intercropped with different ridges of peanuts to analyze the effect of different intercropping modes on agronomic traits,yield and economic benefit of Peanut.Results:Main stem height and first lateral branch length of peanut decreased with the increase of intercropping ridges.The number of full fruits,fruit weight per plant,100-fruit weight and 100-kernel weight increased with the increase of the number of peanut intercropping ridges.3-ridge intercropping peanut yield was almost equal to monoculture,which were significantly higher than 1-ridge(two rows)and 2-ridge(four rows)intercropping.So peanut-maize 3∶2 intercropping model was optimum and could achieve the maximum economic yield.
