Abstract: The experiment was carried out in the cornfield in the seventh(2018) and eighth (2019)year of geese cultivation,and the effects of the co-cultivation mode of breeding goose in cornfield on the dry aboveground weight,nutrient accumulation and yield of corn at different growth stages were studied,so as to lay a theoretical foundation for better popularization and application of this mode in cornfield.The results showed that the dry weight and total N,P,K accumulation of stems,leaves and grains of corn of the co-cultivation mode were significantly increased compared with conventional corn cultivation mode.Compared with conventional corn cultivation mode, the total N, P, K accumulation of grain of the co-cultivation mode increased by 34.77%—41.95%, 32.30%—46.66%, 34.69%—42.26% respectively.In 2018 and 2019,the corn yield of the co-cultivation mode increased by 19.15% and 22.32%,respectively.In conclusion,the co-cultivation mode of breeding goose in cornfield could promote the accumulation of dry matter and nutrient of aboveground part,and increase corn yield.

摘要： 在养鹅第7年（2018年）和第8年（2019年）的玉米田进行试验，探讨玉鹅种养模式对玉米各生育时期地上部干质量、养分积累量及产量的影响，为更好地推广应用玉鹅种养模式奠定理论基础。结果表明，与常规玉米种植模式相比，玉鹅种养模式下玉米植株茎、叶、籽粒干质量和全N、P、K积累量总体上均显著提高，其中籽粒全N、P、K积累量分别提高34.77%~41.95%、32.30%~46.66%、34.69%~42.26%，2018、2019年产量分别提高19.15%、22.32%。综上，玉鹅种养模式可促进玉米地上部干物质和养分积累，提高玉米产量。
