为了筛选出适宜黑龙江省西部半干旱地区的玉米与绿豆的间作模式，通过田间试验，研究了绿豆、玉米间作对玉米产量、绿豆产量及其主要农艺性状的影响。结果表明：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和明显的经济效益优势，当绿豆与玉米的间作比例为2∶1时，其复合群体的总经济效益最高；绿豆与玉米间作模式的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。
為瞭篩選齣適宜黑龍江省西部半榦旱地區的玉米與綠豆的間作模式，通過田間試驗，研究瞭綠豆、玉米間作對玉米產量、綠豆產量及其主要農藝性狀的影響。結果錶明：與綠豆和玉米分彆單作相比，綠豆、玉米間作模式具有較大的生產潛力和明顯的經濟效益優勢，噹綠豆與玉米的間作比例為2∶1時，其複閤群體的總經濟效益最高；綠豆與玉米間作模式的邊際效應使玉米的一些農藝性狀得到改善，而綠豆的一些性狀得到減弱，這是受到負邊際效應影響的結果。

In order to screen out intercropping pattern of mung bean and maize ,which was suitable for west semi-arid region of Heilongjiang province ,the effects of intercropping for maize and mung bean on yield and ag-ronomic characters were investigated by field experiments .The results showed that compared with monocul-ture ,intercropping pattern had yield-increasing potential and economic benefit advantage ,the economic benefit was the highest when the intercropping ratio of mung bean and maize was 2∶1 .In the mode of intercropping for maize and mung bean ,some agronomic characters of maize were improved by marginal utility ,and some agro-nomic characters of mung dean were weaken by anti-marginal utility .
