分析甜玉米的高效栽培模式及效益。将迪甜6号当作试验材料,探究甜玉米和蔬菜(辣椒与马铃薯)间作、小麦复种甜玉米、1a2茬与1a1茬几种栽培模式的经济效益。甜玉米的栽培模式按照经济效益高低依次排列为1a2茬、甜玉米间作辣椒、甜玉米间作马铃薯、小麦复播甜玉米和1a1茬,获得收益分别为95246.29、68142.2、66508.65、56723.5和35882.06元/hm~2,而且不同模式间的两两比较均具有统计学意义(P<0.05);其中一年两茬模式的总效益比1a1茬高61364.23元/hm~2;小麦复种甜玉米的效益比小麦单种高出39086.5元/hm~2。甜玉米的几种不同的栽培模式获得的经济效益差异较大,农户要结合当地的具体情况合理选择间套种模式,使甜玉米的栽培效益提高。
Analysis of efficient cultivation mode and benefit of sweet corn. Using Di Tian 6 as a test material, the economic benefits of several cultivation modes of sweet corn and vegetable (pepper and potato), wheat multiple crop sweet corn, 1a2 crop and 1a1 crop were explored. The cultivation pattern of sweet corn was ranked as 1a2 stubble according to the economic benefits, with sweet corn intercropped with potatoes, sweet corn intercropped with potato, wheat with sweet corn and 1a1 stubble, the gains were 95246.29, 68142.2, 66508.65, 56723.5 and 35882.06 yuan / hm ~ 2, and the pairwise comparisons of different patterns were statistically significant (P <0.05). The total benefit of two cropping patterns in one year was 61364.23 yuan / hm ~ 2 higher than that of 1a1. The benefit of wheat multiple cropping sweet corn was lower than that of wheat Single higher than 39086.5 yuan / hm ~ 2. The economic benefits obtained by several different cultivation modes of sweet corn are quite different. Farmers should choose the intercropping mode reasonably according to the specific conditions of the local area so as to improve the cultivation efficiency of sweet corn.
