[目的]研究甜玉米5种种植模式间经济效益的差异。[方法]以迪甜6号为材料,研究了甜玉米一年一茬、一年两茬栽培、以及甜玉米与小麦、蔬菜(马铃薯、辣椒)间套复种的5种种植模式的种植效益。[结果]甜玉米一年两茬栽培、甜玉米与小麦、蔬菜(马铃薯、辣椒)间套复种的种植效益均高于甜玉米单作。一年两茬种植效益最高,两茬合计93 937.5元/hm2,抛去平均投资18 480元/hm2,纯收益增加41 610元。小麦复播甜玉米模式较小麦单播模式收益增加39 060元/hm2;抛去平均投资13 560元/hm2,纯收益增加25 500元。甜玉米间作马铃薯种植效益为71 460元/hm2;套播辣椒种植效益63 750元。[结论]甜玉米5种种植模式间经济效益存在极显著差异。农户可根据当地实际情况,选择最适宜的间套种模式,提高甜玉米种植效益。
[Objective] The research aimed to study the difference of economic benefits among five planting modes of sweet corn. [Method] With Di Tian 6 as material, planting efficiency of five planting modes of sweet corn, double cropping of one year and double cropping of sweet corn, wheat, vegetables (potato and pepper) was studied. [Result] The planting efficiency of sweet corn and double cropping of sweet corn and wheat and vegetables (potato and pepper) in one year was higher than that of single sweet corn. The highest yield was achieved in two crops a year, with a total of 93,937.5 yuan / hm2 for both crops and an average investment of 18,480 yuan / hm2, an increase of 41,610 yuan in net income. The yield of wheat replanting sweet corn increased by 39 060 yuan / hm2 compared with that of wheat unicast; while the average investment of 13 500 yuan / hm2 was dropped and the net income increased by 25 500 yuan. Sweet potato intercropping potato planting efficiency of 71 460 yuan / hm2; set sowing pepper planting benefits 63 750 yuan. [Conclusion] The economic benefits of five kinds of planting patterns of sweet corn had extremely significant difference. According to local conditions, farmers can choose the most suitable intercropping model to improve the profitability of sweet corn planting.
