Abstract: Six households agricultural production systems were defined based on investigating and analyzing production situation of households in 3 geo-economic districts in transition zone of cropping and pasture(Chifeng, Inner Mongolia).Three production systems, e.g., pasture-pig system, cropping-cattle fattening system and agro-animal husbandry system,were selected through ecological assessment. The improved suggestion for the systems was provided according to existing problems of these systems.

Key words: shading, summer maize, grain development, endogenous hormones, kernel number per ear.
