Abstract:: The influence of different plant row spaces on spring maize yield and water use efficiency was investigated under the suitable for mechanical harvesting of different row spacing cropping patterns through the Loess Plateau Dryland in order to provide theoretical basis for the productivity of spring maize. XY335 with compact and high yield was selected as the test variety, suitable for mechanized harvesting 55 cm and 75 cm two plant row spacing were set up. By planting distance adjusting setting 6.0×10⁴ plant/hm², 7.5×10⁴ plant/hm², 9.0×10⁴ plant/hm², and 10.5×10⁴ plant/hm² four planting density, in a row positioning experiment in 2014 and 2015, the influence of the plant row spacing on spring maize growth and water use efficiency were examined. Results showed that compared with 55 cm row spacing, 75 cm row spacing in dry conditions can effectively delay leaf senescence, SPAD value, leaf area and leaf area index are still high in mature period, the green leaf gave support for the increase of photosynthetic product. Different plant row spacing cultivation modes have different WUE, spinning WUE_F increases with increase of density, WUE_F were high in two types of plant row spacing under the densities of 9.0×10⁴ plant/hm² and 10.5×10⁴ plant/hm² in 2014 and 2015; WUE_H were high in 55 cm row spacing under densities of 9.0×10⁴ plant/hm² and 10.5×10⁴ plant/hm² in 2014, WUE_H were high in 75 cm row spacing under the densites of 7.5×10⁴ plant/hm² and 10.5×10⁴ plant/hm², WUE_H were high in two kinds of plant row spacing under densities of 6.0×10⁴ plant/hm² and 10.5×10⁴ plant/hm² in 2015. Production water use efficiency irregularly changed in 55 cm row spacing, and increased with the increase of density in 75 cm row spacing. 55 cm and 75 cm row spacing can be used as the row spacing of spring maize under mechanical harvest in Dryland of the Loess Plateau, 75 cm row spacing with the planting density of 7.5×10⁴ plant/hm² can be used as a best compact set of planting pattern of spring maize in the test area in terms of soil moisture change, leaf area index, SPAD value, harvest index and yield and water use efficiency.
