Abstract
[Objective]In order to explore the effect of different groove ridge planting patterns on spring corn yield and water use efficiency on Jinzhong semi-arid areas.[Methods]On the premise of covering film on the ridge,Set the following planting patterns:A was ridge planting with ridge and furrow of equal size,B was furrow planting with ridge and furrow of equal size,C was ridge planting with the wide ridge and the narrow furrow,D was ridge planting with the narrow ridge and the wide furrow,CK was bare land which was not coated as the control group,researching for the impacts of different treatments on soil physical and chemical properties,water use efficiency.[Results]The results showed that:The influence of different sets on soil properties were different especially,C treatment of soil moisture content was 1.39 % higher than CK on average,soil porosity was 4 % higher than CK,storage moisture effect was best and organic growth was the largest,improving the effect was most pronounced on soil physical and chemical properties.Through the analysis of crop water consumption and production,Water use efficiency of different sets order was C >A>B>D>CK,C treatment of water use efficiency was 48.05% higher than CK,and the highest yield which was 47.79 % higher than CK.It was concluded that the optimal spring corn ridge and furrow planting pattern was C.[Conclusion]From spring maize yield and soil physical and chemical properties and water use efficiency into consideration,recommended in jinzhong area widely adopted ridge planting with the wide ridge and the narrow furrow,furrow width was 50 cm,ridge width was 70 cm,line spacing was 60cm,plant spacing was 30 cm.关键词
