摘要
为了客观地评价西北沿黄灌区不同作物间套作大豆的产出效果,进一步补充完善各栽培模式,应用土地当量比、产量当量、产值当量等不同量化指标对该区早熟马铃薯套作大豆、玉米间作大豆、小麦套作大豆、亚麻套作大豆及豌豆套作大豆的种植模式进行了分析,同时对5种模式的经济效益进行了评价。结果表明:与单作农田相比,早熟马铃薯套作大豆、玉米间作大豆、小麦套作大豆、亚麻套作大豆及豌豆套作大豆的种植模式土地利用效率分别提高了54%、34%、52%、52%、66%,单位面积产量分别为单作农田的1.39,1.28,1.48,1.55,1.64倍,单位面积产值分别为单作农田的1.43,1.31,1.54,1.53,1.69倍。从盈利看,依次为早熟马铃薯套作大豆、玉米套作大豆、豌豆套作大豆、小麦套作大豆及亚麻套作大豆模式,分别为20 033.48,11 786.85,11 312.02,9 941.03,9 748.05元·hm-2。
In order to quantitatively evaluate the benefits of different cropping patterns of soybean in Northwest irrigation districts along Yellow river, we adopted the concept of land equivalent ratio, yield equivalent and value of output equivalent, and analyzed the cropping patterns of early potato/soybean, wheat/soybean, corr＇/soybean, oil flax/soybean and pea/soybean. Compared with monocuhure, land use efficiency of five patterns raised by 54% , 34% , 52% , 52% and 66% , unit area yield increased by 39%, 28%, 48%, 55% and 64%, unit area output value enhanced by 43%, 31%, 54%, 53% and 69%, respectively. The benefits of five cropping patterns in descending order were early potato/soybean, corn//soybean, pea/soybean, wheat/soybean and oil flax/soybean, the profit was 20 033.48, 11 786.85, 11 312.02, 9 941.03 and 9 748.05 yuan· ha - 1 , respectively.
