采用天冬单作、玉米单作和天冬 -玉米套作 3种种植模式 ,考查了整个生产过程中其主要生产资料和劳动力的投入以及产值等关键指标。对不同种植模式的经济效益对比分析结果表明 ,天冬 -玉米套作比天冬单作增收 2 1 .8%,比玉米单作增收 5 6 4 .9%。天冬单作虽比玉米单作增收 4 4 6 .0 %,但天冬种植三年后才能收获药材 ,没有短期收益。因此 ,3种模式中天冬 -玉米套作的效果最佳。这一研究结果为种植业提供了一条“粮 -药间套”的有效增益模式。
Three kinds of planting modes, as - winter single cropping, single cropping of corn and asparagus - corn sheathing, were adopted to examine the key indicators such as the input of their main means of production, labor force and output value in the whole production process. The comparative analysis of the economic benefits of different planting modes showed that asparagus-maize casing increased the yield by 21.8% compared with that of asparagus, and increased the yield by 56.49% over that of corn alone. Asparagus single crop increased 44.60% compared with single corn, but asparagus can be harvested three years after planting, there is no short-term gains. Therefore, the three kinds of patterns astringent - corn cover the best effect. The result of this study provides an effective mode of profit for the crop plantation.
