According to the plots experiment in recent years and the production practice of compact summer maize yield in Weifang City, we conclude 13 key points to increase the yield of compact summer maize in wheat field. Supporting cultivation techniques: increase the amount of organic fertilizer; enough moisture sowing enough to ensure that a seedling preservation; reasonable increase of strains, give full play to the superiority of the group to increase production; prevent seedling size, improve seedling field uniformity; early seedling stage, promoting Miao early seedling nurturing seedlings; re-bosial fertilization, lay the foundation for high yield; pest control pest, for maize to create a good reproductive environment; timely cultivation of loose soil and improve soil permeability; timely removal of male, to change the direction of nutrient distribution make up attack Grain fertilizer, and promote spike large grain weight; timely irrigation, to meet the physiological water; appropriate late harvest, increase photosynthetic accumulation and other supporting cultivation techniques, which significantly increased summer maize production
