中文摘要	为明确华北寒旱区主栽作物的茬口适应性机制与轮作效果,提出适宜区域种植的轮作组合,本研究于2015-2019年采用交叉式设计,对马铃薯、蚕豆、饲用玉米、莜麦、甜菜5种作物进行了以年际间为重复的轮作定位试验。结果表明,各茬口马铃薯、莜麦、甜菜产量分别是连作的1.30~1.68、1.28~1. 48、1.25~1.48倍,甜菜茬蚕豆产量较连作减产10.58%,莜麦茬、甜菜茬饲用玉米产量较连作减产9.10%~15.42%; 10种轮作组合的轮作土地当量比(LERr)值为1.09~1.68,与连作相比,均表现为有利效应,其中莜麦马铃薯、甜菜马铃薯、饲用玉米马铃薯、蚕豆马铃薯、莜麦甜菜的LERr值较高。蚕豆、饲用玉米作物耐连作;就产量而言,华北寒旱区适宜种植的轮作组合为莜麦马铃薯、甜菜马铃薯、饲用玉米马铃薯、蚕豆马铃薯和莜麦甜菜。
英文摘要	To understand mechanisms of crop adaptability to various previous crop croppings, evaluate crop performance on the croppings, and identify suitable crop combinations for rotation of major crops in the cold and arid region of Northern China. A five-year field experiment was conducted using five crops from 2015 to 2019, including potato (Solanum tuberosum), faba bean (Vicia faba), forage maize (Zea mays), oat (Avena sativa), and beet (Beta vulgarwas). Yields of potato, oat, and beet in rotation were 1.30-1.68, 1.28-1.48, and 1.25-1.48 times of those in continuous cropping of single crops, respectively. Yield of faba bean on beet cropping was 10.58% lower than that of continuous faba bean while yield of forage maize on oat or beet stubble was 9.10%-15.42% lower than that of continuous forage maize. The LERr of 10 crop combinations was 1.09-1.68, indicating positive effects of rotation. Combinations of oat potato, beet potato, forage maize potato and faba bean potato had higher LERr, indicating faba bean and forage maize might be more durable of continuous cropping. In terms of productivity, suitable crop combinations for rotation in the area were oat potato, beet potato, forage maize potato, faba bean potato and oat beet.
