Abstract:

The analysis of technology and benefit in maize field of large area high yield record of 71th farm in Xinjiang Production and Construction Crops shows: National maize 700hm 2 large-area high yield record with yield of 18 414.0 kg/hm 2 (1 227.6kg/mu) were created in 2014, and net profit reached 24 118.20 yuan/hm 2 (1 607.88 yuan/mu); yield reached 18 447.0kg/hm 2 (1 229.8kg/mu) in 2017, as well as net profit reached 16 659.75yuan/hm 2 (1 110.65 yuan/mu), which realized maize high-yield and high-efficiency cooperation promotion. Compared with traditional production, high yield maize combined full mechanization production technology with core of grain mechanical harvest, high yield cultivation techniques with core of high-density population planting, high-quality group regulation, and green production technology with focus of green prevention and control, straw returning, fertilizer reduction, maize green increase of yield and efficiency was achieved through the large-scale, standardized production and unified operations management, which setted up a succeeded case for modern maize production.

Key words: Maize, High yield record, High-density planting, Green production, Full mechanization, Cost accounting
