摘要
[Objective] In order to research differences of economic benefits among 5planting patterns of sweet corn. [Method] Planting benefit of five kinds of planting patterns of Ditian6 were studied. They were one cropping of sweet corn per year,two cropping of sweet corn per year, multiple sowing of wheat and sweet corn, intercropping of sweet corn and vegetables（potatoes, peppers）. [Result] Planting benefit of two cropping of sweet corn in a year, multiple sowing of wheat and sweet,intercropping of sweet corn and vegetables（potatoes, peppers） were higher than that of sweet corn monoculture. The benefit of two cropping of sweet corn per year was the highest, which was 93 937.5 yuan/hm^2. The pure income increase was 41 610 yuan if the average investment of 18 480 yuan/hm^2 was eliminated. Compared with wheat monoculture, the benefit of multiple sowing of wheat and sweet increased39 060 yuan/hm^2. The pure income increase was 25 500 yuan if the average investment of 13 560 yuan/hm^2 was eliminated. The planting benefit of intercropping of sweet corn and potato was 71 460 yuan, and that of intercropping of sweet corn and pepper was 63 750 yuan. [Conclusion] There were extremely significant differences among the economic benefits of 5 planting patterns of sweet corn. According to local actual situation, farmers can choose the most suitable pattern to improve the planting efficiency of the sweet corn.
[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。
