在东北农牧区粮食安全、生态环境安全和畜牧业可持续发展面临严峻挑战的情况下，找出优势间作模式和制约其推广的制约因素至关重要。采用完全随机区组设计，设置5个处理，即玉米单作平行、玉米单作宽窄行、苜蓿单作、玉米间作宽窄行苜蓿和玉米间作宽窄行苜蓿。结果表明，玉米单作宽窄行交替栽培的透光率、产量和产值均优于平行栽培。间作条件下，玉米与苜蓿宽行间作是最优的间作方式，苜蓿与玉米生态位互补性强，有利于发挥间作优势，优化资源利用，提高产量和经济效益。说明苜蓿/玉米间作具有明显的优势，适合于东北农牧交错区。
Given the growing challenges to food and eco-environmental security as well as sustainable development of animal husbandry in the farming and pastoral areas of northeast China, it is crucial to identify advantageous intercropping modes and some constraints limiting its popularization. In order to assess the performance of various intercropping modes of maize and alfalfa, a field experiment was conducted in a completely randomized block design with five treatments: maize monoculture in even rows, maize monoculture in alternating wide and narrow rows, alfalfa monoculture, maize intercropped with one row of alfalfa in wide rows and maize intercropped with two rows of alfalfa in wide rows. Results demonstrate that maize monoculture in alternating wide and narrow rows performed best for light transmission, grain yield and output value, compared to in even rows. When intercropped, maize intercropped with one row of alfalfa in wide rows was identified as the optimal strategy and the largely complementary ecological niches of alfalfa and maize were shown to account for the intercropping advantages, optimizing resource utilization and improving yield and economic incomes. These findings suggest that alfalfa/maize intercropping has obvious advantages over monoculture and is applicable to the farming and pastoral areas of northeast China.
