玉米绿豆间作效应分析

Effects of Maize (Zea mays L.) Intercropping with Mungbean (Phaseolus radiatus)

[目的]研究绿豆(Phaseolus radiatus)/玉米(Zea mays L.)间作对玉米、绿豆产量和主要农艺性状的影响,筛选出适宜黑龙江省西部半干旱地区玉米与绿豆的间作模式。[方法]采用田间试验。绿豆/玉米间作比例分别为1∶2、2∶4、4∶2、4∶6、6∶4、2∶1,分别以玉米单作和绿豆单作为对照。[结果]与绿豆和玉米分别单作相比,绿豆/玉米间作模式具有较大的生产潜力,有明显的经济效益优势,当绿豆与玉米的间作比例为6∶4时复合群体的总经济效益最高;绿豆与玉米间作,边际效应使玉米的一些农艺性状得到改善,而绿豆的一些性状得到减弱,这是受到负边际效应影响的结果。[结论]黑龙江省西部半干旱地区,绿豆与玉米的间作比例以6∶4较适宜。

[ Objective ] The aim was to study the effects of mungbean - maize intcrcropping on their yield and agronomic characters, and to screen out the suitable mungbean - maize intercropping mode in semi - arid areas of western Heilongjiang Province. [ Method ] The pot test was used. And the mungbean - maize intercropping proportion was 1 ： 2, 2： 4, 4： 2, 4： 6, 6： 4, 2： 1, resp. , taking maize and mungbean single culture as control. [ Result] Compared with single culture, the intercropping had bigger production potential, increased the economic benefits, and the economic benefit of the treatment mungbean - maize intercropping proportion 6：4 was the highest ; In the mode of maize intercropping with mungbean, some agronomic characters of maize improved by magrginal utility, while some agronomic characters of mungdean weakened by anti - magrginal utility. [ Conclusion] The suitable intercropping proportion of mungbean - maize was 6：4 in semi - arid areas of western Hcilongjiang Province.
