摘  要：
通过田间试验,研究河西绿洲灌区玉米与绿肥间作模式对作物产量和经济效益的影响。结果表明,3行玉米间作2行针叶豌豆时的玉米生物产量和籽粒产量均为最高,分别高于对应的不间作绿肥处理0.2%和0.95%,但差异不显著。2行玉米间作3行毛苕子时的绿肥干草产量最高,2年的平均产量为3 901kg·hm-2,显著高于其它处理。2行玉米间作3行针叶豌豆时的绿肥豆类籽粒产量最高,2年的平均产量为2 225 kg·hm-2,同样显著高于其它处理。3行玉米间作3行针叶豌豆时的经济效益最高,为35 038元·hm-2,比2行玉米不间作绿肥处理每公顷增值7 848元,增收28.86%,比3行玉米不间作绿肥处理每公顷增值5 853元,增收20.05%。因此,在河西绿洲灌区进行玉米种植时,若以收获玉米籽粒为主,则适宜采用3行玉米间作2行针叶豌豆种植模式;若以经济效益为主,则适宜采用3行玉米间作3行针叶豌豆的种植模式。

摘  要：
Effects of different intercropping systems of corn and different varieties of green manure on crop yield and economic benefit were studied by the field experiment in Hexi oasis irrigation area. The results showed that corn biomass and grain yield were the highest under the planting system of three rows of corn intercropping two rows of needle leaf pea,the biomass and grain yield were respectively higher by 0. 2% and 0. 95% than that of no intercropping treatments,but their difference was not significant. The yield of green manure hay was the highest under the planting system of two rows of corn intercropping three rows of hairy vetch,the average yield of two years was 3 901 kg·hm- 2significantly higher than other treatments.The legumes grain yield of green manure was the highest under the planting system of two rows of corn intercropping three rows of needle leaf pea,the average yield of two years was 2 225 kg·hm- 2significantly higher than other treatments. The economic benefit was the highest under the planting system of three rows of corn intercropping three rows of needle leaf peat,reached 35 038 yuan·hm- 2,compared with the two rows and three rows of corn no intercropping green manure treatments,the economic increased 7 848 yuan·hm- 2and 5 853 yuan·hm- 2,the income increased by 28. 86% and 20. 05%,respectively. Thus,the highest corn grain could be harvested by the optimal planting system of three rows of corn intercropping two rows of needle leaf pea in Hexi oasis irrigation area; the best economic benefit could be obtained by the planting system of three rows of corn intercropping three rows of needle leaf pea in Hexi oasis irrigation area.
