Abstract: In order to clarify the effects of different production modes on the growth of maize at seedling stage, the weed community status and maize status at seedling stage were investigated and analyzed by using the method of contrast with the production mode of breeding goose （RGC） in corn field. The results showed that the above ground biomass of weed communities was slightly lower than that of CK, and there was no significant difference between treatments. The leaf length, leaf width, leaf area, stem diameter, fresh weight and dry weight of maize of RGC treatment were higher than that of control （CK）, and there was no significant difference between the treatments, but plant height of the RGC treatment was significantly higher than the CK, and the chlorophyll content of the RGC was significantly lower than that of the CK, however, the maize yield of RGC was significantly lower than that of CK. After 4 years of long-term positioning tests, the treatment of RGC increased the species and biomass of the weed community, and improved the growth of the maize at the seedling stage in general, the final reduction of corn yield in autumn was due to later management factors.
