[Abstract]
Through 1 000-mu(666.7 m2) square and 10 000-mu(666.7 m2) piece demonstration, high-yield po-tential research drives farm to achieve a comprehensive single-season maize yield of "1 ton per mu". The input and output of Qitai farm high-yield field were investigated in this study. The results showed that the average yield of the 1 000-mu square was 18 385.5 kg/ha in 2014, and the net profit reached 18 955.5 yuan/ha; the average yield of 81 000 mu was 16 230 kg/ha, and the net profit was 9 060 yuan/ha in 2016, which realized maize high-yield and high-efficiency coordination. The green production technology of close planting and high yield, and full mechaniza-tion with the core of cultivars suitable for high-density population planting and mechanical harvest, dripping for seedling emergence and high-quality group regulation, mechanical grain harvesting and full mechanization cultiva-tion techniques, and combined with fine land preparation, high-quality seeds and precise sowing technology, chemi-cal regulation, water and fertilizer integration technology, straw returning, grain drying and storage, and the largescale standardized production and management, whole-process cost accounting provides a model for modern maize production.
