摘要: 为探索大兴安岭西麓轮作休耕对土壤水分含量和作物产量的影响,2017年在特泥河试验站进行了小麦和油菜不同轮作休耕模式试验.试验表明:结果休耕模式下小麦和油菜不同生育时期农田土壤体积含水量和水分利用效率均大于连作,小麦的穗数和穗粒数以及油菜的单株有效角果数和每角粒数也呈现休耕〉轮作〉连作.休耕后翌年种植小麦和油菜,产量分别达到了4670.17 kg/hm2和3296.20 kg/hm2,显著高于对照连作小麦和油菜以及油菜—小麦和小麦—油菜轮作模式下的产量.

Abstract: In order to explore the effects of rotation and fallow on soil volumetric moisture content and crop yield in the West of the Great Khingan, the experiment on the different rotation model with wheat and rape was carried out in the Tenihe experiment station in 2017. The results showed thai the soil volumelric moisture and water use efficiency of comfield and rape field under rotation in fallow mode at difterent growth stages were much greater than that of continuous cropping, and the number of spike and number of kernels of wheat and effective pod number per plant and seed number per pod of rapeseed also showed fallow〉rotation〉continnous cropping. The yield of wheat and rape in the following year after fallow, and the yield reached 4 670.17 kg/hm^2 and 3 296.20 kg/hm^2, respectively, which was significantly higher than that of the control continuous cropping wheat and rape and rape-wheat and wheat-rape rotation patterns.
