本项研究系在当地现行农作制中利用带状种植冬小麦地的预留行间作不同冬性豆科牧草,通过比较评价为当地牧业发展增产饲料探索高效的草麦间作系统。结果表明:小麦间紫云英(70%)+饲用碗豆(30%)、小麦间白三叶草和小麦间长柔毛野碗百三个间作系统,在其小麦产量高于对照(带状单作小麦)3.09~12.89%的情况下,增产了词料,获得较高的饲料价值(DM1.05~1.22t/公顷,TDOM0.78~0.89t/公顷,CP0,29~0.36t/公顷,ME0.57~0.68×104MJ/公顷)。小麦间紫云英(70%)+饲用蚕豆(3%)处理在增产饲料的同时,对土壤也产生了较好的影响。这些间作系统提高了农田生态位的利用效率和单位面积土地的物质生产能力,在不影响粮食生产的情况下增产饲料,有利于促进养殖业的发展和农牧结合。
In this study, different winter leguminous forages were used for the intercropping of winter wheat growing in strip-growing areas in the current local cropping system. The high-efficiency wheat-wheat intercropping system was explored to increase feed production for the development of local animal husbandry. The results showed that the yield of wheat was higher than that of the control (strip shape). The yield of wheat was higher than that of the control (DM1.05 ~ 1.22 t / ha, TDOM0.78 ~ 0.89 t / ha, CP0, t0) were increased with the increase of 3.09 ~ 12.89% 29 ~ 0.36 t / ha, ME0.57 ~ 0.68 × 104 MJ / ha). The treatment of wheat with Astragalus membranaceus (70%) and fodder broad bean (3%) also had a good effect on the soil while increasing feed production. These intercropping systems improve the utilization efficiency of farmland niche and material production capacity per unit area of land, and increase feed production without affecting food production, which is conducive to promoting the development of aquaculture and the combination of agriculture and animal husbandry.
