摘要

本研究探讨了大平原南部特有的雨水灌溉种植系统在杂草竞争下的经济效益。种植系统包括小麦-沼泽地、小麦-大豆和小麦-高粱轮作。比较了不同杂草压力下各种植系统的净收益。无论采用哪种耕作方法和杂草压力水平如何，在较长规划期限内耕作的生产者都会选择双季稻。规划期较短的生产者会在杂草压力较大时采用小麦-耕地系统，而在杂草压力较小时采用双茬种植。

Economic Performance of Rainfed Wheat-Double Crop Systems under Weed Competition

This study examines the economic performance of rainfed cropping systems endemic to the Southern Great Plains under weed competition. Cropping systems include tilled and no-till wheat-fallow, wheat-soybean, and wheat-sorghum rotations. Net returns from systems are compared under different levels of weed pressure. Producers operating over longer planning horizons would choose to double-crop regardless of the tillage method used and weed pressure level. Producers operating under shorter planning horizons would implement wheat-fallow systems when weed pressure is high and double crop when weed pressure is low.
